Problem

Repeated /improve runs on Azure DevOps can turn one review into a growing collection of duplicate or near-duplicate threads. Developers may apply a suggestion, reject it, defer it to a backlog item, or explain why it is not appropriate, but a later run does not reliably retain that context. The same finding can then return as a new comment.

The discussion is also fragmented:

  • the suggestions summary can be posted again instead of updated
  • applied suggestions can remain active
  • replies to suggestion threads are not considered by later runs
  • developers cannot naturally mention the configured Azure DevOps identity to ask a follow-up question in the same thread
  • an unchanged incremental run can spend time generating suggestions even though there is nothing new to review

Expected behavior

From a developer's perspective, suggestion reviews should behave like one continuous conversation:

  • the first /improve run reviews the pull request and publishes one summary plus relevant inline suggestions
  • later runs do not repost an existing suggestion at the same location
  • the existing summary is updated in place
  • an exact applied suggestion is marked as fixed
  • replies such as "defer this" or "this is intentional" inform later suggestion runs
  • a question that mentions PR-Agent's Azure DevOps identity is answered in the same PR or line thread
  • /improve -i reviews only changes after the latest suggestions pass and exits without a model call when no commits are new

Implementation

This change keeps the behavior scoped to Azure DevOps:

  • extends persistent inline-comment fingerprints with the complete normalized finding, suggestion code, file, and line range
  • reads both marked and markerless existing suggestion roots while excluding replies from deduplication
  • keeps the suggestions summary persistent even when comment history is disabled
  • reconciles active suggestion threads against the current head and marks exact applied changes as fixed
  • supplies bounded suggestion-thread discussions to later suggestion runs as untrusted context
  • supports configured or discovered Azure DevOps identities for mentions and replies in the originating thread
  • preserves existing slash commands while adding mention-based questions
  • resets provider caches when the pull request or its threads change
  • degrades safely when discussion history or current file content cannot be read

Documentation covers Azure identity configuration, persistent suggestions, discussion context, and incremental /improve usage.

Validation

Live Azure DevOps Services test

Tested end-to-end against a live Azure DevOps Services pull request with 16 commits and 6 changed files, using the same configuration and model as production.

The final test sequence produced these results:

  1. A clean full /improve run created one summary thread and four inline suggestion threads.
  2. Replaying three exact published suggestion payloads created zero new threads.
  3. Publishing a summary update edited the existing summary thread and created zero new threads.
  4. Running /improve -i without new commits exited before the model request.
  5. The thread set remained unchanged after the incremental no-op.

Automated checks

  • 126 passed in the focused Azure suggestion, incremental, deduplication, question, and webhook suites
  • 2101 passed, 1 skipped, 1 xfailed in the complete unit suite
  • TOML validation, import ordering, and changed-line length checks pass
  • Python compilation and git diff --check pass

High-Level Assessment

The following are alternative approaches to this PR:

1. External DB/cache for suggestion state
  • ➕ Stronger durability if comments are edited/deleted
  • ➕ Richer state model (triage/decisions) without prompt-size constraints
  • ➖ Adds operational dependency and migrations
  • ➖ More setup complexity and failure modes than marker-based state
2. Use Azure thread metadata/properties instead of HTML markers
  • ➕ Keeps state attached to threads without embedding markers in comment text
  • ➕ Potentially less brittle than parsing comment bodies
  • ➖ May be limited by ADO API support/permissions
  • ➖ Still needs bootstrap path for existing markerless threads and PR-level fallback comments
3. Status-only dedup (active/fixed/wontFix) without fingerprinting
  • ➕ Simpler model and smaller prompt footprint
  • ➕ Aligns with native review workflow
  • ➖ Cannot reliably distinguish same suggestion content at different ranges
  • ➖ Cannot detect exact-applied matches without comparing suggestion code to file content

Recommendation: The chosen approach (marker-based fingerprints + bounded/untrusted discussion context + reconciliation against head content) fits Azure DevOps well: no external infrastructure, bootstraps markerless history, and degrades safely when thread history or file content can’t be read. Keep the context limits and untrusted-data framing (already implemented) to reduce prompt-injection and cost risk.

Action required

1. Failed update loses output 🐞 Bug ☼ Reliability
Description
In the new history-disabled persistent path, _cleanup_progress_comment deletes the progress
comment even when Azure failed to update the persistent summary, because
AzureDevopsProvider.edit_comment catches the API error and returns normally. A transient update
failure can therefore leave the run's generated suggestions unpublished while removing the only
visible progress/result comment.
Code

pr_agent/tools/pr_code_suggestions.py[R488-489]

Evidence
The new max_previous_comments <= 0 branch calls publish_persistent_comment and then always
invokes the cleanup helper. Azure delegates persistent publishing to the base implementation, whose
update success is inferred from edit_comment returning, but Azure's edit_comment suppresses
exceptions; cleanup then overwrites and removes the progress comment.

2. Fallback overwrites persistent summary ✓ Resolved 🐞 Bug ≡ Correctness
Description
_publish_fallback_suggestions prefixes PR-level fallback comments with the same `## PR Code
Suggestions ✨` header used to identify the persistent summary, and in dual-publishing mode those
fallbacks are posted after the real summary so subsequent persistent updates can mistakenly edit the
newer fallback thread and leave the actual summary stale. Additionally, the Azure history-disabled
persistence branch only routes the normal suggestions result through publish_persistent_comment,
while the no-suggestions path still edits the progress thread or posts a new comment, resulting in a
second ## PR Code Suggestions ✨ thread and an unchanged prior summary on reruns with no
suggestions.
Code

Relevance

●●● Strong

Recent persistent-comment precedents favor updating the stable summary and isolating
fallback/cleanup paths to prevent duplicate threads.

PR-#2404

ⓘ Recommendations generated based on similar findings in past PRs

Evidence
The fallback publisher now applies _SUGGESTIONS_HEADER to both aggregated and individual fallback
comments, and the normal table summary uses that same header as its initial_header, which the base
persistent updater relies on to find and edit the first matching issue comment; because Azure
returns comments newest-first and dual publishing posts inline/fallback suggestions after publishing
the table summary, the newest fallback comment can become the first match and be edited instead of
the real summary. Separately, the Azure special-case persistence keeps the summary up-to-date only
when going through publish_persistent_comment_with_history, but the no-suggestions branch calls
edit_comment(progress_response, ...) or publish_comment(...) directly while still emitting the
same summary header, meaning it won’t locate/update the prior persistent summary and will instead
create or reuse a separate header-matching thread.

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
Azure PR code-suggestions publishing can create multiple comments that share the same identifying header (`## PR Code Suggestions ✨`), causing persistent updates to target the wrong thread (often a newer fallback or no-suggestions/progress comment) and leaving the real summary stale—especially in dual-publishing mode and in Azure history-disabled persistence.

## Issue Context
- Fallback comments need to remain discoverable for deduplication and incremental anchoring, but they must not satisfy the persistent-summary header match used by the persistent updater.
- Azure’s history-disabled branch currently applies persistent-comment updating only for the normal suggestions result; reruns that produce no suggestions bypass that path and instead edit the progress comment or publish a new comment, even though they use the same header.
- Progress cleanup should remain best-effort, but terminal outcomes (including no-suggestions) should consistently update the persistent summary thread rather than creating competing header-matching threads.

7. Fallback duplicates bypass batch dedup ✓ Resolved 🐞 Bug ≡ Correctness
Description
When an inline suggestion’s end offset cannot be resolved, the code queues it as a PR-level fallback
and continues before adding its markers/fingerprints to local_fingerprints. As a result,
identical unresolved-range suggestions in the same batch are all appended to fallback_suggestions
and emitted together as duplicate fallback sections, and any post-publication handling cannot
retroactively prevent those duplicates.
Code

pr_agent/git_providers/azuredevops_provider.py[R274-278]

+            if store is not None and not has_marker(body):

Azure dedup bugs are routinely accepted, but this branch already registers fallback fingerprints in
the shown diff.

PR-#2424
PR-#2381

ⓘ Recommendations generated based on similar findings in past PRs

Evidence
The fingerprint checks rely on local_fingerprints to deduplicate within a single run before
queuing/publishing suggestions, and the normal inline path adds body/code fingerprints into that
set. In the unresolved-range branch, the code appends the original suggestion to the fallback list
and exits early via continue, so it never reaches the later marker/local-fingerprint registration
block; consequently, two otherwise identical unresolved-range suggestions in the same model run both
survive the pre-queue dedup and end up in the accumulated fallback list. The fallback publisher then
publishes the entire queued list in one PR-level comment/section, meaning duplicates are already
published before any later store/update or add_body-style post-publication step can act, matching
the established pattern that local fingerprints must handle within-batch dedup while persistent
updates occur only after successful publication.

Unresolved-range (cannot resolve inline end offset) fallback suggestions are currently queued without going through the local marker/fingerprint registration, so identical suggestions in the same batch are not deduplicated and are published as duplicate PR-level fallback sections.

## Issue Context
- The unresolved-range branch appends the suggestion to the fallback queue and `continue`s before the marker/local-fingerprint block executes.
- The unmatched-file fallback path already marks its fallback body and records local fingerprints before appending, which avoids within-batch duplicates.
- Cross-run/persistent store updates should remain post-publication, but within-batch dedup must be enforced via `local_fingerprints` before publishing the aggregated fallback batch; post-publication calls cannot remove duplicates already emitted and don’t add keys for unmarked bodies.

8. Developer becomes agent alias ✓ Resolved 🐞 Bug ≡ Correctness
Description
Agent identity discovery classifies any comment beginning with a review/suggestion header—including
the generic **Suggestion:** prefix—as agent-authored, so a developer posting matching text has
their identity added to PR-Agent's mention aliases. Later mentions of that developer can therefore
trigger PR-Agent unexpectedly and consume a model call under the wrong identity.
Code

pr_agent/git_providers/azuredevops_provider.py[R1070-1071]

+        prefixes = tuple(prefix for group in cls._INCREMENTAL_ANCHOR_PREFIXES.values() for prefix in group)
+        return content.lstrip().startswith(prefixes)
Relevance

●● Moderate

The identity-discovery risk is plausible and intent-aligned, but no close historical precedent
confirms this specific alias false-positive.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence
Every author whose comment satisfies _is_agent_comment contributes ID, display name, and unique
name as aliases. _is_agent_comment accepts all incremental anchor prefixes, and the suggestions
group explicitly contains the generic **Suggestion:** text; the webhook then accepts a mention
whenever its identity matches any discovered alias.

9. Question arg injection ✓ Resolved 🐞 Bug ⛨ Security
Description
In Azure DevOps mention-triggered /ask_line commands, the user-supplied question is appended
unquoted, so any tokens like "--foo=bar" inside the question can be interpreted by PR-Agent as
settings overrides (and removed from the actual question), unintentionally mutating runtime config
for that request and altering behavior.
Code

pr_agent/servers/azuredevops_server_webhook.py[R151-154]

+    encoded_path = quote(path, safe="")
+    return (f"/ask_line --line_start={start_line} --line_end={end_line} --side={side} "

+            f"--origin_comment_id={comment_id} {question}").rstrip()

●● Moderate

Security concern is plausible, but searches found no closely matching accepted or rejected
command-injection precedent.

PR-#2703

ⓘ Recommendations generated based on similar findings in past PRs

Evidence
The webhook constructs a /ask_line command by concatenating the raw question text into the
command string. PR-Agent later tokenizes command strings with shlex and applies
update_settings_from_args, which treats any token starting with -- and containing = as a
configuration override. Therefore, --key=value appearing in the question can be consumed as a
setting update instead of remaining in the question.

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
Azure DevOps mention-based questions are converted into a synthetic `/ask_line ... {question}` command. The `{question}` portion is appended without shell-quoting, but `PRAgent` tokenizes commands with `shlex` and then applies `update_settings_from_args` to any `--key=value` tokens.

This means a normal natural-language question that includes `--something=...` (or a malicious one) can:
- be treated as a config override for the current request, and
- be removed from the question passed to the tool.

## Issue Context
This affects the new mention-based question flow (Azure webhook → `/ask_line`). The risk is both correctness (question content mangling) and security (unintended config mutation on untrusted input).

## Fix Focus Areas
- pr_agent/servers/azuredevops_server_webhook.py[151-154]

## Implementation sketch
- When building the `/ask_line` command, wrap `question` with `shlex.quote(question)` (import `shlex`) so it is passed as a single argument token.
- Ensure existing behavior (file_name encoding, origin_comment_id, etc.) remains unchanged.
- Add/extend a unit test to cover a mention question containing `--some_key=1` and assert it remains part of the question text and does not become a settings override.

Compliance ID 2694656 requires isort-style grouping and ordering of imports; however, the modified
import lists are not sorted by imported names. In pr_agent/tools/pr_code_suggestions.py, the
imported names are out of order (e.g., get_* functions appear after provider classes), and in
pr_agent/tools/pr_questions.py the ordering similarly violates isort expectations (e.g.,
get_git_provider should precede GitLabProvider under isort-style sorting), demonstrating
non-compliance with the required ordering rules.

The question argument finding is addressed in f879847. The remaining import-order finding is not applicable: both cited files already match the repository’s configured isort output, and isort --check-only passes for both.

The new boolean is consumed on one path only. max_history_len defaults to 4, so most runs take the history branch, where the return is dropped at line 459 and the progress note is removed regardless. Not a regression, main does the same, but git_provider.py:392 is its only consumer.

Worth saying in the description which of these need the opt-in. Threaded /ask and line-question history are on by default for every Azure user, and main gates the latter on isinstance(self.git_provider, GithubProvider), so Azure gains something new. The reconcile pass is inert without config.persistent_inline_comments, since it only sees threads carrying the marker line 195 writes.

Hard conflict with #2722, which adds raise here. Worth agreeing which way before either merges.

I traced the overlap from #2722 and narrowed its scope so we should be able to keep both behaviors.

#2722 no longer changes AzureDevopsProvider.edit_comment() or the Azure /improve path. It only keeps the shared persistent-comment failure contract: an explicit False edit result is treated as a failed update, and fallback_on_error=False prevents lifecycle updates from creating duplicate persistent comments.

So #2724 can keep ownership of the Azure True/False contract and its /improve handling.

If #2722 lands first, when rebasing #2724 onto the updated main, the Azure-specific changes can stay as-is; the only overlapping shared-publisher hunk should be dropped in favor of the version already in main.

Thanks for the work on this one, and two things before it can move.

It no longer merges: pr_agent/tools/pr_questions.py conflicts with main at eb5b0abf, and GitHub has the branch as dirty.

And the overlap with #2722 is not resolved, despite the note above. #2722's head still adds raise to AzureDevopsProvider.edit_comment() where this PR returns False, so the two still collide on azuredevops_provider.py and git_provider.py. I have said the same on #2722. The cleanest order is this one landing first, since your True/False contract is what makes #2722's guard work at all, after which #2722 drops its Azure change.
