Rename *Content to *Message and add ToolOutput/ToolUseMessage types

[cboos]

Part of "Message Refactoring Phase 2" (see in dev-docs).

I'll continue later on this one, but thought it would be a good idea to share this first step already.

---

Complete naming refactoring (RENAME_CONTENT_TO_MESSAGE.md):

Phase 1: Rename Pydantic transcript models

• UserMessage → UserMessageModel
• AssistantMessage → AssistantMessageModel

Phase 2: Rename all MessageContent subclasses from *Content to *Message

• UserTextContent → UserTextMessage, AssistantTextContent → AssistantTextMessage
• ToolResultContentModel → ToolResultMessage, ThinkingContentModel → ThinkingMessage
• SlashCommandContent → SlashCommandMessage, etc.

Phase 3: Create ToolOutput/ToolUseMessage types

• Add ToolOutput union (ReadOutput, EditOutput, ToolResultContent)
• Add ToolUseMessage dataclass wrapping ToolInput with metadata
• Update ToolResultMessage to use output: ToolOutput field
• Fix Output classes to be plain dataclasses (data containers, not MessageContent)

Phase 4: Update CSS_CLASS_REGISTRY with new type names

Updated all formatters, renderer, parser, and tests for new naming.

📝 Walkthrough

Walkthrough

Renames Content/ContentModel types to Message variants, adds MessageMeta and TemplateMessage/RenderingContext, moves parsing to new factory modules, replaces many formatters with input/output-centric APIs, updates renderer/template flows and tests to use the new Message-based pipeline.

Changes

Cohort / File(s)	Summary
Models & core types claude_code_log/models.py	Renamed many Content/ContentModel → *Message types; added MessageMeta, MessageContent/ContentItem unions, ToolInput/ToolOutput unions, ToolUseMessage/ToolResultMessage, and adjusted fields (e.g., ToolResultMessage.output).
Factories & parsing claude_code_log/factories/*, claude_code_log/factories/*.py	New factory package (meta, transcript, user, assistant, tool, system). Adds create_transcript_entry, create_*_message, create_tool_input/output; centralizes parsing and detection logic previously in parser.py.
Renderer core & template plumbing claude_code_log/renderer.py, claude_code_log/html/renderer.py, claude_code_log/renderer_timings.py	Introduces TemplateMessage and RenderingContext, generate_template_messages/_render_messages flows, new pairing/dedup/sidechain cleanup, per-message formatter dispatch, and updated timing reporting (msg_id).
HTML formatters & utils claude_code_log/html/__init__.py, claude_code_log/html/*.py, claude_code_log/html/tool_formatters.py, claude_code_log/html/utils.py, claude_code_log/html/templates/*	Public exports and function signatures switched to Message types; many format_*_content renamed to input/output variants (e.g., format_bash_input/output, format_askuserquestion_input/output); templates now expect tuples (message, title, html, timestamp) and use is_session_header helper.
Tool parsing & factory logic claude_code_log/factories/tool_factory.py	New comprehensive tool parsing and mapping: TOOL_INPUT_MODELS, lenient parsers, TOOL_OUTPUT_PARSERS, create_tool_input, create_tool_use_message, create_tool_result_message, and parse_*_output helpers.
Transcript & meta factories claude_code_log/factories/transcript_factory.py, claude_code_log/factories/meta_factory.py	create_transcript_entry dispatcher, create_message_content/create_content_item, usage normalization, and create_meta to produce MessageMeta from raw transcript entries.
System / user / assistant factories claude_code_log/factories/system_factory.py, claude_code_log/factories/user_factory.py, claude_code_log/factories/assistant_factory.py	Detection helpers (is_system_message, is_bash_input/output, is_command_message) and create_*_message helpers (slash, bash, command output, assistant/thinking); token-usage formatting helper added.
Parser slimming claude_code_log/parser.py	Removed many parse_* public functions (parse_slash_command, parse_command_output, parse_bash_input/output, etc.), retaining minimal extract_text_content and parse_timestamp; parsing moved to factories.
Cache & converter claude_code_log/cache.py, claude_code_log/converter.py	Switched deserialization to factories: parse_transcript_entry → create_transcript_entry and updated imports/calls.
HTML templates & JS snapshots claude_code_log/html/templates/*, test/__snapshots__/*	Template shape changed to use (message, title, html, timestamp) tuples; ancestry class prefix standardized to d- (removed session-), session id attributes and client-side folding/navigation adjusted.
Tests test/*.py	Tests updated to use Message and MessageModel types, replaced parse_ calls with create_ factories, and renamed formatter usages to new input/output functions.
Docs dev-docs/*	Added/updated migration and refactor docs (RENAME_CONTENT_TO_MESSAGE.md, MESSAGE_REFACTORING2.md, TEMPLATE_MESSAGE_REFACTORING.md); removed obsolete plans (PLAN_PHASE12.md, REMOVE_ANTHROPIC_TYPES.md).

Poem

🐰 I hopped through files with nimble feet,

Content names bowed, and Messages meet,
Factories stitched each clever seam,
TemplateMessages chase the dream,
Logs now hum — a tidy, bright treat! 🥕

⚠️ Outside diff range comments (1)

dev-docs/messages.md (1)

867-867: Stale reference: Comment still uses old *Content names.

The reference mentions "SystemContent, HookSummaryContent" but should say "SystemMessage, HookSummaryMessage" to match the rename.

🔎 Proposed fix

-  - [system_formatters.py](../claude_code_log/html/system_formatters.py) - SystemContent, HookSummaryContent formatting
+  - [system_formatters.py](../claude_code_log/html/system_formatters.py) - SystemMessage, HookSummaryMessage formatting

🧹 Nitpick comments (1)

claude_code_log/html/tool_formatters.py (1)

742-795: Consider extracting common dispatcher logic.

The new format_tool_use_from_input function duplicates the dispatcher logic from format_tool_use_content (lines 702-740). Both functions have nearly identical type checks and formatter calls.

Consider extracting a shared helper function that both can delegate to, which would reduce maintenance burden and keep the dispatch logic DRY.

🔎 Example refactor approach

+def _dispatch_tool_formatter(parsed: "ToolInput", fallback_dict: Optional[dict[str, Any]] = None) -> str:
+    """Shared dispatcher for tool input formatting."""
+    if isinstance(parsed, TodoWriteInput):
+        return format_todowrite_content(parsed)
+    if isinstance(parsed, BashInput):
+        return format_bash_tool_content(parsed)
+    # ... other type checks ...
+    
+    # Fallback handling
+    if isinstance(parsed, dict):
+        return render_params_table(parsed)
+    if fallback_dict is not None:
+        return render_params_table(fallback_dict)
+    return f"<pre>{parsed}</pre>"
+
 def format_tool_use_content(tool_use: ToolUseContent) -> str:
-    parsed = tool_use.parsed_input
-    # Dispatch based on parsed type...
+    return _dispatch_tool_formatter(tool_use.parsed_input, tool_use.input)

 def format_tool_use_from_input(parsed_input: "ToolInput", tool_name: str, raw_input: Optional[dict[str, Any]] = None) -> str:
-    # Dispatch based on parsed type...
+    return _dispatch_tool_formatter(parsed_input, raw_input)

69-78: SystemMessage correctly defined.

Renamed from SystemContent with appropriate docstring. The structure (level, text fields) is preserved.

---

152-179: ToolResultMessage and ToolUseMessage correctly structured.

ToolResultMessage uses the output: ToolOutput field with a forward reference, and ToolUseMessage provides a clean wrapper with typed input, tool metadata, and raw input fallback. This aligns with the Phase 3 refactoring goals.

---

385-399: ReadOutput correctly structured as a plain dataclass.

Per Phase 3 of the refactoring, output types are now data containers (not MessageContent subclasses), stored within ToolResultMessage.output.

---

498-506: ToolOutput union correctly defined.

The union includes specialized output types (ReadOutput, EditOutput) with ToolResultContent as the generic fallback. The comment correctly notes that more specialized outputs will be added as they're implemented.

---

771-789: UserMessageModel and AssistantMessageModel correctly renamed.

The rename from UserMessage/AssistantMessage to UserMessageModel/AssistantMessageModel clarifies these are Pydantic models for JSONL parsing, distinct from the dataclass MessageContent types used for rendering.

---

815-824: Transcript entries correctly updated.

UserTranscriptEntry.message and AssistantTranscriptEntry.message now reference UserMessageModel and AssistantMessageModel respectively, maintaining consistency with the renamed Pydantic models.

dev-docs/TEMPLATE_MESSAGE_CHILDREN.md (1)

51-77: Add language specifiers to fenced code blocks.

The code blocks showing tree structures (lines 51-58, 61-66, 72-77) lack language specifiers. While these are ASCII art diagrams rather than code, adding a language hint (e.g., text or plaintext) improves accessibility and silences linter warnings.

Proposed fix

 Initial tree structure (before cleanup):
-```
+```text
 tool_use (Task)      ← 0 children (pair reordering moves tool_result here)
 ...

Apply similar changes to the other two blocks at lines 61 and 72.

claude_code_log/cache.py (1)

175-178: Consider moving the import to module level.

The create_transcript_entry import appears twice in different function scopes (lines 175 and 260). While this works correctly, it would be cleaner and more maintainable to import it once at the module level alongside other imports.

🔎 Suggested refactor

Move the import to the top of the file near line 25:

 from .parser import parse_timestamp
+from .factories import create_transcript_entry
 from .models import TranscriptEntry

Then remove the local imports at lines 175 and 260.

Also applies to: 260-263

claude_code_log/factories/meta_factory.py (1)

10-33: Clean factory implementation with a minor simplification opportunity.

The create_meta function correctly maps transcript entry fields to MessageMeta. One small nitpick:

Line 29 uses getattr(transcript, "isMeta", False) or False, but the or False is redundant since getattr already returns False as the default value.

🔎 Minor simplification

-        is_meta=getattr(transcript, "isMeta", False) or False,
+        is_meta=getattr(transcript, "isMeta", False),

claude_code_log/factories/assistant_factory.py (1)

27-44: Token usage may display None when token counts are absent.

If usage.input_tokens or usage.output_tokens is None, the formatted string will show "Input: None | Output: None". Consider adding a guard or displaying "N/A".

     """Format token usage information as a display string.
 
     Args:

117-143: Consider logging or warning on fallback to TextContent.

When create_content_item falls back to TextContent for unknown/disallowed types or exceptions, this silently converts potentially malformed data. For debugging purposes, consider logging a warning when fallback occurs.

🔎 Proposed enhancement

+import logging
+
+logger = logging.getLogger(__name__)

     item_data: dict[str, Any],
     type_filter: Sequence[str] | None = None,

         content_type = item_data.get("type", "")

         if type_filter is None or content_type in type_filter:
             model_class = CONTENT_ITEM_CREATORS.get(content_type)
             if model_class is not None:
                 return cast(ContentItem, model_class.model_validate(item_data))

         # Fallback to text content for unknown/disallowed types

`449-480`: **The `_looks_like_bash_output` heuristic may have false positives.**

The function returns `True` for any content containing Unix-style paths (line 472), which could match file paths in non-Bash output (e.g., Read tool output mentioning file paths). However, this is used for `has_ansi` flag setting which is cosmetic, so false positives have minimal impact.


Consider renaming to `_has_terminal_like_content` to better reflect that it detects terminal/command-line patterns rather than strictly identifying Bash output, or tighten the path pattern to require command-like context.

`1300-1306`: **Consider reusing the original message's metadata for dedup notices.**

The `DedupNoticeMessage` is created with `MessageMeta.empty()`, which has empty `session_id`, `timestamp`, and `uuid`. While this works because the message remains in its tree position, reusing the original child's metadata would be more robust for any future code that accesses these fields.

⚠️ Potential issue | 🟡 Minor

getattr fallback won't apply when level is explicitly None.

getattr(transcript, "level", "info") only uses the default "info" if transcript.level is absent as an attribute, not when it's None. Per SystemTranscriptEntry, level: Optional[str] = None, so accessing it when unset yields None, not "info".

🔎 Proposed fix

     # Create structured system content
     meta = create_meta(transcript)
-    level = getattr(transcript, "level", "info")
+    level = transcript.level or "info"
     return SystemMessage(level=level, text=transcript.content, meta=meta)

🤖 Prompt for AI Agents

In claude_code_log/factories/system_factory.py around lines 84 to 87, the
current getattr call only falls back when the attribute is missing but not when
transcript.level is explicitly None; change the logic to treat None as absent by
first retrieving the attribute (e.g. level = getattr(transcript, "level", None))
and then setting level = "info" if level is None (or use a coalescing
expression) before returning SystemMessage so the default "info" applies when
level is None.

Verify duck-typed image content handling.

Lines 463-465 handle duck-typed image content by checking for source attribute and type == "image", then call item.model_dump() without verifying the method exists. This assumes duck-typed objects are Pydantic models or compatible. If a duck-typed image object lacks model_dump(), it will raise an AttributeError at runtime. Consider adding a defensive check or error handling, or document the required interface for duck-typed image content.

⚠️ Potential issue | 🟡 Minor

Preview may display raw ANSI escape codes when has_ansi is true.

When output.has_ansi is true, the full content correctly uses convert_ansi_to_html(), but the preview at line 352 uses escape_html(content[:200]). This means ANSI escape sequences will appear as literal text (e.g., [32m) in the preview, which looks ugly.

🔎 Suggested fix

     # For longer content, use collapsible details
-    preview_html = escape_html(content[:200]) + "..."
+    if output.has_ansi:
+        preview_html = convert_ansi_to_html(content[:200]) + "..."
+    else:
+        preview_html = escape_html(content[:200]) + "..."

🤖 Prompt for AI Agents

In claude_code_log/html/tool_formatters.py around lines 348-352, the preview
HTML is built with escape_html(content[:200]) which leaves ANSI escape sequences
visible when output.has_ansi is true; change the preview branch so that when
output.has_ansi is true you run the ANSI-to-HTML conversion on the preview slice
(i.e., convert_ansi_to_html(content[:200])) and use that result plus "..." for
the preview, otherwise keep using escape_html for non-ANSI content; ensure you
only convert the preview slice (not the whole content) to avoid expensive work
and to keep the preview consistent with the full converted output.

⚠️ Potential issue | 🟡 Minor

Documentation shows incomplete ToolOutput union.

The ToolOutput union documented at lines 398-403 only lists ReadOutput, EditOutput, and ToolResultContent. However, per models.py (lines 1042-1052), the full union includes WriteOutput, BashOutput, TaskOutput, AskUserQuestionOutput, and ExitPlanModeOutput.

🔎 Suggested fix

 # ToolOutput is a union type for tool results
 ToolOutput = Union[
     ReadOutput,

In dev-docs/messages.md around lines 386 to 404, the documented ToolOutput union
is incomplete; update the union to match models.py (lines 1042-1052) by adding
WriteOutput, BashOutput, TaskOutput, AskUserQuestionOutput, and
ExitPlanModeOutput to the listed types (so the union becomes ReadOutput,
EditOutput, WriteOutput, BashOutput, TaskOutput, AskUserQuestionOutput,
ExitPlanModeOutput, and ToolResultContent), and adjust any surrounding prose to
reflect the full set of possible tool outputs.

claude_code_log/html/renderer.py (1)

1-510: Add DedupNoticeMessage to CSS_CLASS_REGISTRY in claude_code_log/html/utils.py.

DedupNoticeMessage is missing from the CSS_CLASS_REGISTRY, causing it to fall back to msg.type ("dedup_notice") which is not recognized in timeline.html. This breaks feature parity between the main transcript view and timeline component. Add the entry:

DedupNoticeMessage: ["system", "dedup-notice"],

Update timeline.html messageTypeGroups to include:

'dedup-notice': { id: 'dedup-notice', content: '🔄 Dedup Notice', style: 'background-color: #ffeee1;' },

And add 'dedup-notice' to the classList check in buildTimelineData() around line 72.

claude_code_log/renderer.py (2)

618-653: Guard aggregation against UsageInfo fields that may be None

UsageInfo declares all token fields as Optional[int], but _collect_session_info (around line 1711) sums input_tokens and output_tokens without checking for None:

usage = assistant_message.usage
sessions[session_id]["total_input_tokens"] += usage.input_tokens
sessions[session_id]["total_output_tokens"] += usage.output_tokens

This is inconsistent with the cache token fields (lines 1714–1717), which already have if guards. If older or partial logs omit these fields, you'll hit TypeError: unsupported operand type(s) for +=: 'int' and 'NoneType'. Coerce None to 0 to match the pattern used for cache tokens:

usage = assistant_message.usage
- sessions[session_id]["total_input_tokens"] += usage.input_tokens
- sessions[session_id]["total_output_tokens"] += usage.output_tokens
+ sessions[session_id]["total_input_tokens"] += usage.input_tokens or 0
+ sessions[session_id]["total_output_tokens"] += usage.output_tokens or 0

518-577: Avoid log_timing lambdas that reference locals assigned in the with body

In generate_template_messages, you use lambdas that capture ctx and session_nav inside the with body. If _render_messages or prepare_session_navigation raises an exception before the assignment completes, log_timing's finally block will evaluate the lambda, but the local will be unbound, raising UnboundLocalError and masking the real exception.

with log_timing(lambda: f"Render messages ({len(ctx.messages)} messages)", t_start):
    ctx = _render_messages(...)  # If this raises, ctx is unbound when lambda is evaluated

Use static phase names for these blocks:

- with log_timing(lambda: f"Render messages ({len(ctx.messages)} messages)", t_start):
+ with log_timing("Render messages", t_start):
      ctx = _render_messages(filtered_messages, sessions, show_tokens_for_message)

- with log_timing(
-     lambda: f"Session navigation building ({len(session_nav)} sessions)", t_start
- ):
+ with log_timing("Session navigation building", t_start):
      session_nav = prepare_session_navigation(sessions, session_order, ctx)

Or initialize the locals before the context manager if the message counts are important for debugging.

🧹 Nitpick comments (6)

claude_code_log/html/renderer.py (1)

233-234: Parameter name shadows built-in.

The parameter name input shadows Python's built-in input() function. While this doesn't cause runtime issues in this context, it's a code smell that can reduce readability.

🔎 Suggested fix

-    def format_ToolUseContent(self, input: ToolUseContent) -> str:
-        return render_params_table(input.input)
+    def format_ToolUseContent(self, content: ToolUseContent) -> str:
+        return render_params_table(content.input)

claude_code_log/models.py (1)

55-151: Message / Tool model refactor looks coherent and type-safe

The split between Pydantic JSONL models (e.g. TextContent, ToolUseContent, ToolResultContent, UsageInfo, transcript entries) and dataclass-based render/tool models (MessageMeta, MessageContent subclasses, ReadOutput/EditOutput/TaskOutput, ToolOutput) is clean and matches the documented architecture. Field types and unions line up with how factories and the renderer consume them, and forward references are used safely.

One minor follow-up you might want later: for AskUserQuestionItem.options and AskUserQuestionInput.questions you’re using =[] defaults on BaseModel fields; switching to Field(default_factory=list) would be more idiomatic and quieten strict type/lint tools, but it isn’t functionally blocking.

claude_code_log/renderer_timings.py (1)

24-30: Align terminology: these timings now carry message_id, not UUID

timing_stat now records (duration, msg_id) from _current_msg_id, but the report_timing_statistics docstrings still describe the last element as uuid. Consider renaming those doc params/comments to message_id (or clarifying “id/uuid”) to avoid confusion when reading or consuming the stats.

Also applies to: 107-116, 120-123

test/test_template_data.py (1)

389-437: Consider isolating _message_counter per test to avoid hidden coupling

TestTemplateMessageTree._message_counter is a class‑level counter that only increments; today it’s only used in one test, but if future tests rely on specific message_index values, they could become order‑dependent. Resetting this counter in a fixture or inside _create_message when msg_id is provided would make the helper safer for reuse.

dev-docs/MESSAGE_REFACTORING2.md (1)

29-40: Add language to fenced code blocks to satisfy markdownlint

The factory layout and function‑signature snippets are in fenced blocks without a language spec. To address markdownlint’s MD040, tag them, e.g.:

```text
factories/
├── __init__.py
...

def create_user_message(meta: MessageMeta, content_list: list[ContentItem], ...) -> ...

This keeps the docs as‑is but quiets the linter.

`974-1058`: **Minor: reuse top‑level `datetime` import in `_reorder_paired_messages`**

`_reorder_paired_messages` does a local `from datetime import datetime` even though `datetime` is already imported at the top of the module. This is harmless but redundant; you can drop the inner import and use the module‑level one.

Learning: In the claude-code-log fold UI (claude_code_log/templates/transcript.html), the fold button tooltips describe the ACTION on click, not the current state. Button 1 (fold-one) when showing ▼ will "Fold (all levels)" because hiding immediate children transitively hides all descendants. Button 2 (fold-all) when showing ▼▼ will "Fold (to 1st level)" because it keeps immediate children visible while hiding deeper descendants.

`5644-5645`: **Snapshot changes are consistent with the unified `d-` ancestry format.**

The JavaScript filtering logic in `handleFoldOne`, `handleFoldAll`, and `setInitialFoldState` now correctly uses `classList.filter(cls => cls.startsWith('d-'))` to identify ancestor relationships. This aligns with the broader refactor that standardizes on the `d-` prefix for ancestry classes and separates `data-session-id` as a distinct attribute on session headers.

The changes are mechanical and consistent across all snapshot test cases.

`1-111`: **Imports are well-organized and comprehensive.**

The imports correctly reflect the Message-centric refactoring with proper organization of system, user, assistant, and tool-related types. The addition of timing utilities and tool formatters aligns with the enhanced rendering pipeline.

---

`264-313`: **Tool title methods follow consistent dispatch pattern.**

The title generation methods use `cast()` extensively for type narrowing. This is acceptable given the dispatcher pattern in the base `Renderer` class ensures type safety before calling these methods. The conditional logic in `title_TaskInput` appropriately handles multiple optional fields (description, subagent_type).

---

`315-364`: **Timing integration properly implemented.**

The `_flatten_preorder` method correctly integrates timing instrumentation for Markdown and Pygments operations. The return type documentation is clear, and the safe handling of optional `msg.meta` prevents potential AttributeErrors.

---

`366-412`: **Generate method correctly integrates timing and new helpers.**

The method properly unpacks and reports operation timings, and correctly uses the new `is_session_header` helper in the template rendering context. The timing instrumentation via context managers is appropriate and non-invasive.

`136-166`: **Session lookup via `data-session-id` is correct and future‑proof**

Switching `findSessionForMessage` to read `prev.dataset.sessionId` matches the new session header markup (`data-session-id='{{ message.session_id }}'`) and avoids brittle id parsing. This should remain stable even if id formats change.

<summary>claude_code_log/html/templates/components/session_nav.html (1)</summary><blockquote>

`14-35`: **Anchor now correctly targets message‑index based IDs**

Using `#msg-d-{{ session.message_index }}` lines up with `id="msg-{{ message.message_id }}"` where `message_id` is `d-{index}`. As long as `prepare_session_navigation` always sets `message_index` for sessions that appear here (which it does via `ctx.session_first_message`), navigation will reliably scroll to the right header. Worth keeping in mind if any future caller constructs `session_nav` without a corresponding header.

<summary>claude_code_log/html/templates/transcript.html (1)</summary><blockquote>

`72-141`: **Template / JS updates correctly track `TemplateMessage` + `d-*` ancestry**

The transcript template and associated JS now consistently treat `TemplateMessage` as the source of truth:

- Header loop unpacks `(message, message_title, html_content, formatted_timestamp)` and uses `is_session_header(message)`; this matches the new `_flatten_preorder` contract from the renderer.
- Session headers and regular messages use `id='msg-{{ message.message_id }}'` and ancestor classes `d-{{ ancestor_index }}`, which align with `TemplateMessage.message_id`/`ancestry`.
- Fold handlers (`handleFoldOne`, `handleFoldAll`, `setInitialFoldState`) correctly interpret ancestry solely via `cls.startsWith('d-')`, and treat `targetId` as the `d-*` class, so immediate‑child vs descendant logic remains O(n) and accurate.
- Filters and counts still key off semantic CSS classes (`user`, `assistant`, `thinking`, `tool_use`, `tool_result`, `sidechain`) attached via `css_class_from_message(message)` and work with the new message types.

Overall this wiring looks consistent with the new rendering model; I don’t see hierarchy or filter regressions from the template side.

`9-22`: **Tests exercise the new title dispatch correctly**

The updated tests for `TemplateMessage` creation and `Renderer.title_content` use `MessageMeta` plus `UserTextMessage` / `AssistantTextMessage` / `SessionHeaderMessage` in the same way the production code does (meta on content, `TemplateMessage(content)` wrapper). Assertions against `"User"`, `"Assistant"`, and `"Session Header"` match the current `Renderer` title methods and fallback behavior.

This gives good coverage of the new dispatch surface and should catch regressions in title logic.

538-568: Avoid capturing ctx/session_nav in log_timing lambdas before assignment

Both log_timing calls:

• lambda: f"Render messages ({len(ctx.messages)} messages)" and
• lambda: f"Session navigation building ({len(session_nav)} sessions)"

reference locals that are only assigned inside the with block. If _render_messages or prepare_session_navigation raises, the log_timing context’s finally will still call the lambda, causing an UnboundLocalError and masking the original exception.

Switch these to static phase names (or compute the counts after the call) to keep timing helpful without breaking error reporting.

Suggested simplification for safer timing

-    with log_timing(lambda: f"Render messages ({len(ctx.messages)} messages)", t_start):
-        ctx = _render_messages(filtered_messages, sessions, show_tokens_for_message)
+    with log_timing("Render messages", t_start):

1274-1315: TaskOutput-aware task result extraction fixes earlier dedup gap

_extract_task_result_text now prefers TaskOutput.result when ToolResultMessage.output is a parsed TaskOutput, and falls back to ToolResultContent string or structured list content with _normalize_for_dedup. This resolves the previous issue where TaskOutput-based results weren’t considered for deduplication.

---

1318-1405: DedupNoticeMessage now preserves sidechain meta and original assistant message

_cleanup_sidechain_duplicates correctly:

• Removes the first sidechain UserTextMessage while adopting its children, and
• Replaces the last matching sidechain AssistantTextMessage with a DedupNoticeMessage built from child_content.meta, keeping sidechain/session flags and storing the original AssistantTextMessage in original.

This matches the refactor’s “content.meta as source of truth” goal and addresses prior feedback about using MessageMeta.empty().

🧹 Nitpick comments (2)

claude_code_log/factories/tool_factory.py (1)

84-96: Consider more specific exception handling.

The bare except Exception: pass blocks (also at lines 135-136, 178-179, 188-189) silently swallow all exceptions. While this is appropriate for lenient parsing, consider catching specific exceptions (e.g., ValidationError, KeyError, TypeError) to avoid masking unexpected errors during development.

🔎 Example: More specific exception handling

-            except Exception:
-                pass
+            except (ValidationError, KeyError, TypeError, ValueError):
+                # Skip invalid items in lenient mode
+                pass

1645-1652: Guard against None token fields in UsageInfo when aggregating

UsageInfo.input_tokens / output_tokens are declared as Optional[int], but _collect_session_info adds them directly:

sessions[session_id]["total_input_tokens"] += usage.input_tokens
sessions[session_id]["total_output_tokens"] += usage.output_tokens

If any parsed usage omits these fields (they stay None), this will raise TypeError. Safer to treat missing values as 0 before summing.

Possible defensive aggregation change

-                usage = assistant_message.usage
-                sessions[session_id]["total_input_tokens"] += usage.input_tokens
-                sessions[session_id]["total_output_tokens"] += usage.output_tokens
+                usage = assistant_message.usage
+                input_tokens = usage.input_tokens or 0
+                output_tokens = usage.output_tokens or 0
+                sessions[session_id]["total_input_tokens"] += input_tokens
+                sessions[session_id]["total_output_tokens"] += output_tokens

This keeps behavior identical when tokens are present while avoiding crashes on partial usage objects.

🔇 Additional comments (24)

claude_code_log/factories/tool_factory.py (5)

1-54: LGTM!

Module docstring is clear and imports are well-organized. The factory pattern for tool input/output processing is a good architectural choice.

---

225-251: LGTM!

The fallback strategy (strict validation → lenient parsing → None) is well-designed. The use of cast() is appropriate given the constrained registry types.

---

343-617: LGTM!

The output parsing functions are well-structured with appropriate fallbacks. The use of walrus operators and early returns makes the code clean and readable. The heuristics in _looks_like_bash_output are reasonable for determining terminal output formatting.

---

620-662: LGTM!

The type alias and registry pattern provide clean extensibility. The chained walrus operators with short-circuit evaluation are elegantly used to attempt parsing and fall back gracefully to raw ToolResultContent.

---

665-769: LGTM!

The tool item processing functions provide a clean pipeline from raw content to typed messages. The context dict population is well-documented, and the separation between tool use and tool result processing is clear. Error state propagation through is_error ensures proper handling downstream.

24-33: Timing stats now correctly key off message IDs and align with new callers

Using _current_msg_id in timing_stat and treating timings as (duration, msg_id) tuples matches the new _flatten_preorder integration and keeps report_timing_statistics coherent. The guarded if message_timings: branch also avoids noisy output when only operation timings are present. No issues from a correctness or API‑shape standpoint.

25-45: CSS class registry correctly migrated to Message-based types

The registry now keys off MessageContent subclasses (SystemMessage, UserTextMessage, ToolUseMessage, etc.) with appropriate base classes and dynamic modifiers (system level, tool_result error). This aligns with the new Message model hierarchy and keeps _get_css_classes_from_content simple and extensible.

is_session_header using SessionHeaderMessage content and the updated get_message_emoji checks for CommandOutputMessage / ToolResultMessage.is_error give a clean separation between structural type (via msg.content) and visual type (msg.type). This matches the new TemplateMessage API and should keep templates straightforward.

Also applies to: 139-149, 151-187

48-152: JSONL content and transcript models are coherently structured

The new TextContent/ImageContent/ToolUseContent/ToolResultContent/ThinkingContent models and the TranscriptEntry union give a clear, typed view of the JSONL input. The separation between low‑level content (Pydantic) and higher‑level MessageContent dataclasses looks sound and should work well with the new renderer pipeline.

---

699-723: ToolResultMessage + ToolOutput union design works well with parsed TaskOutput

ToolResultMessage.output using the ToolOutput union (specialized ReadOutput/EditOutput/TaskOutput, etc., plus ToolResultContent as a generic fallback) is a good fit for the renderer. The has_markdown property delegating to isinstance(self.output, TaskOutput) lines up with the new TaskOutput dataclass and the test_task_output_structured_content_markdown expectations.

Also applies to: 921-969, 985-994, 1057-1069

870-885: The review comment is incorrect; the code works as designed in Python 3.10+

In Python 3.9+ (via PEP 585), list[T] and other builtin generic types became callable and work correctly with list[T](). The project targets Python 3.10+, so list[AskUserQuestionOption]() and list[AskUserQuestionItem]() execute successfully and return empty lists without raising TypeError. The existing models instantiate correctly, including when using the default_factory to create empty lists, as demonstrated by the passing test test_format_askuserquestion_empty_input.

The proposed fix to use Field(default_factory=list) is a style preference rather than a necessary correction, and both approaches are valid in Pydantic 2.x.

Likely an incorrect or invalid review comment.

test/test_sidechain_agents.py (2)

200-253: Explore-agent sidechain regression coverage looks solid

The test_explore_agent_no_user_prompt scenario (sidechain starting with assistant messages only) matches the documented Explore pattern and ensures _reorder_sidechain_template_messages / _cleanup_sidechain_duplicates don’t assume a leading sidechain user prompt. This should prevent regressions when handling non‑Plan agents.

---

293-379: Good end‑to‑end coverage for structured TaskOutput markdown rendering

test_task_output_structured_content_markdown exercises the full path from JSONL tool_result with structured content → TaskOutput parsing → ToolResultMessage.has_markdown → HTML output with task-result class and rendered <h2>/<h3>/<code> elements. This directly validates the new ToolOutput plumbing and the TaskOutput‑aware markdown detection.

test/test_template_data.py (2)

10-22: TemplateMessage + Renderer title tests align with new API

Creating TemplateMessage via UserTextMessage/AssistantTextMessage/SessionHeaderMessage and asserting Renderer.title_content(...) gives "User", "Assistant", and "Session Header" verifies the new type‑based title dispatch. Using MessageMeta/MessageMeta.empty() keeps tests in sync with the source‑of‑truth metadata model.

Also applies to: 28-64

---

388-441: Tree helper _create_message is consistent with Message types

The updated _create_message helper now constructs UserTextMessage / AssistantTextMessage / ToolUseMessage / SessionHeaderMessage with MessageMeta, and explicitly sets message_index to keep tree tests deterministic. This matches how RenderingContext.register behaves in production and keeps ancestry/children tests realistic.

claude_code_log/renderer.py (4)

75-111: RenderingContext and TemplateMessage provide a clean render-time abstraction

The new RenderingContext registry plus TemplateMessage wrapper (with derived type, message_id, ancestry, pairing, and token/sidechain helpers) is well-structured and matches how HTML rendering and CSS classes are computed. This should make further per‑Message-type formatting and tree manipulation much easier to reason about.

Also applies to: 129-288

---

620-655: Session summary extraction continues to match leafUuid → session mapping

prepare_session_summaries still prioritizes assistant messages when building the leafUuid → sessionId map, with a backup map for non‑assistant messages. That aligns with how summaries are generated and ensures session_summaries remains stable even after the Message-based refactor.

---

1472-1545: Sidechain reordering still honors agentId-on-tool_result invariant

_reorder_sidechain_template_messages groups sidechain messages by agent_id and only inserts them after main messages where message.type == MessageType.TOOL_RESULT and agent_id matches, with a used_agents guard. This stays compatible with the documented behavior that agentId is only set on Task tool_result messages, not on tool_use, and matches the sidechain insertion semantics described in earlier learnings.

---

1548-1614: Message filtering remains compatible with new content models

_filter_messages continues to:

• Drop SummaryTranscriptEntry and non‑remove QueueOperationTranscriptEntry,
• Keep SystemTranscriptEntry for special handling in _render_messages,
• Skip messages with neither text nor tool/thinking items, and
• Apply should_skip_message.

The additional note about sidechain user prompts now being cleaned up in _cleanup_sidechain_duplicates correctly reflects the new tree‑level dedup behavior.

claude_code_log/html/renderer.py (5)

4-45: HTML renderer import surface and formatter wiring match Message-based API

The imports and use of format_* helpers for system/user/assistant/tool content (including tool input/output types) are consistent with the new MessageContent + ToolInput/ToolOutput model. HtmlRenderer delegates to the right formatter for each Message or tool type and keeps all HTML-specific concerns in the html package.

Also applies to: 53-60, 76-100, 101-107

---

145-201: Per-type format_ and tool input/output formatters are correctly dispatched*

HtmlRenderer implements format_{ClassName} for each key content type and for each ToolInput/ToolOutput class, matching Renderer._dispatch_format’s lookup strategy. ToolUseContent falls back to a params table, and raw ToolResultContent uses the dedicated raw formatter. This keeps HTML concerns localized and makes it easy to extend support for new tool types.

Also applies to: 206-263

---

268-314: Tool title helpers are safely escaped and align with task/exitplan UX

The _tool_title helper and title_*Input methods (especially title_TaskInput and title_BashInput) correctly:

• Read the ToolUseMessage’s input,
• Use escape_html for tool names, descriptions, and subagent types, and
• Add appropriate icons and spans.

This both improves UX (clearer titles) and keeps attribute text safe from injection.

---

315-365: Pre-order flattening integrates timing stats with message rendering

_flatten_preorder now:

• Sets _current_msg_id per TemplateMessage,
• Uses format_timestamp on msg.meta.timestamp,
• Accumulates a flat (message, title, html, formatted_timestamp) list, and
• Seeds _markdown_timings / _pygments_timings via set_timing_var.

The returned operation_timings structure matches report_timing_statistics’s expectations, and DEBUG_TIMING stays opt‑in.

---

366-413: Top-level HTML generation correctly composes template messages and timing

HtmlRenderer.generate:

• Delegates to generate_template_messages for format‑neutral TemplateMessages + session nav,
• Flattens via _flatten_preorder,
• Calls report_timing_statistics with just operation timings when DEBUG_TIMING is on, and
• Renders transcript.html with css_class_from_message, get_message_emoji, and is_session_header.

This fits the new renderer architecture and keeps HTML concerns in one place.

⚠️ Potential issue | 🟠 Major

Add type guard for structured content items.

If the content list contains non-dict items, item.get("type") will raise an AttributeError. Add a type check to handle malformed structured content defensively.

🔎 Proposed defensive fix

 text_parts: list[str] = []
 for item in content:
-    if item.get("type") == "text":
-        text_parts.append(str(item.get("text", "")))
+    if isinstance(item, dict) and item.get("type") == "text":
+        text_parts.append(str(item.get("text", "")))
 return "\n".join(text_parts)

In claude_code_log/factories/tool_factory.py around lines 320 to 340, the loop
assumes each structured content item is a dict and calls item.get("type"), which
will raise AttributeError for non-dict items; update the loop to defensively
check that item is an instance of dict (or Mapping) before accessing .get, skip
or safely coerce non-dict items (e.g., ignore them or convert to string) and
only append text when the type is "text" to avoid exceptions from malformed

Hello @daaain (happy Xmas, btw!), I'm done with this refactoring. Let me explain the context a little bit: after all the "vibe coded changes" I did for restructuring the messages and enhancing the presentation, I felt like I left the code in a sorry state, to the point it was really hard to follow what was happening. Besides, I was motivated to create alternative renderings (Markdown, a la #43) but that would benefit from the various higher level changes I brought (deduplication, pairing, hierarchy). Hence, the attempt to streamline things, clean-up the code, make the creation of alternative renderers easily possible. It's nowhere near perfect, but I think we're back to something manageable, both for us and Claude.

Now, I'll do elsewhere some more clean-ups for glitches that I noticed while working on this (#70), and most importantly, add --format md/markdown support, to verify it's indeed possible to do so easily now (#71).

Hey @cboos, belated merry Christmas to you too 😸

Thanks a lot for this work! In general, I'm not too fussed if some parts of the codebase temporary slide in quality, this is also a really interesting experiment to see how can an open source library be sustainably maintained if coding agents are added to the mix.

I think the important thing is to add tests whenever you notice any behavioural / functional regression, because as long as the test suite is reasonably thorough, we can much easier refactor even big parts of the codebase.

I won't have time to review the PR in detail, but happy for you to merge when you feel like it's ready and can do a release and rebase my SQLite cache branch in a few days once I'm back from visiting family.
