+The OpenSpec workflow for content-only changes (no Go code, no tests) follows a streamlined path: propose creates all artifacts, spec review validates the design, implementation is direct file edits, and code review confirms tag placement and JSON validity. The key gotcha is that review markers (`<!-- spec-review: passed -->` and `<!-- code-review: passed -->`) must be written to tasks.md immediately after reviews pass -- if the session ends before markers are written, the unleash pipeline cannot detect completion on resume and must re-run reviews. Always write filesystem markers before proceeding to the next step.

+
+When implementing protect-tags-slash-commands (issue #74), the change was purely additive markup -- only `<protect>` and `</protect>` tags added to 5 embedded markdown files plus a single `"protectTags": true` line in opencode.json. No Go code, no tests, no MCP protocol changes. The key design decision was section-level granularity (one protect block per logical section, not per line), with a clear taxonomy: protect guardrails/MUST rules, workflows with numbered steps, and session procedures; leave explanatory/advisory content (examples, interpretations, usage patterns) unprotected so DCP can still compress them. The 5 reviewers in spec review and 3 in code review all returned APPROVE with zero blocking findings. The recurring review feedback was that the exact JSON path for `protectTags` in opencode.json should be documented with a concrete snippet -- this was addressed at implementation time by placing it at the top level after `$schema`. For content-only changes like this, the verification tasks (tag count grep, JSON validation, make build, git diff --stat for constitution alignment) are lightweight and effective.

+## Context
+
+Five slash command files in `internal/agentkit/content/commands/` deliver
+workflow instructions to agents as user messages. DCP can compress these
+during long sessions, losing critical steps. The proposal identifies
+adding `<protect>` tags as the mechanism to prevent this, complementing
+prior structural hardening work.
+
+The proposal's constitution alignment confirms this change is PASS on
+Autonomous Collaboration (strengthens agent instruction delivery),
+Composability First (tags are inert without DCP), and Testability (no
+external services needed). Observable Quality is N/A (no tool output
+changes).
+
+## Goals / Non-Goals
+
+### Goals
+- Wrap safety-critical content (invariants, review gates, ordered
+  workflows, exit conditions) in `<protect>` tags across all five
+  command files.
+- Enable `protectTags: true` in `opencode.json` so the DCP engine
+  recognizes the tags.
+- Keep unprotected content available for DCP compression to maintain
+  context budget efficiency.
+
+### Non-Goals
+- Restructuring command file content (already done in prior DCP
+  hardening changes).
+- Adding `<protect>` tags to skill files (skills are delivered as
+  `tool_use` pairs and protected by `protectedTools`).
+- Modifying replicator Go source code or MCP tool behavior.
+- Adding tests for tag presence (the tags are consumed by OpenCode's DCP
+  engine, not by replicator).
+
+## Decisions
+
+### D1: What to protect vs. leave unprotected
+
+**Decision**: Protect content whose loss causes behavioral failure.
+Leave explanatory/contextual content unprotected.
+
+**Protected categories** (from issue #74):
+1. **Guardrails / safety rules** -- invariant sections, MUST/NEVER
+   constraints, review gate requirements.
+2. **Execution checklists / step definitions** -- numbered workflow
+   steps, tool call sequences.
+3. **Exit conditions / resume instructions** -- session end procedures,
+   handoff note structure.
+
+**Unprotected categories**:
+- Section headings (redundant with protected content).
+- Descriptive text explaining *why* a step exists (the step itself is
+  protected).
+- Examples and code blocks that illustrate usage patterns (agents can
+  reconstruct these from tool schemas).
+- "Interpreting Results" guidance in forge-status.md (advisory, not
+  behavioral).
+
+**Rationale**: Over-protecting defeats the purpose of DCP compression.
+The goal is surgical protection of content that, if lost, causes agents
+to skip steps, violate ordering, or bypass gates.
+
+### D2: Protect tag granularity
+
+**Decision**: Use one `<protect>` block per logical section, not per
+line.
+
+For example, in forge.md:
+- One `<protect>` block wrapping the entire Critical Invariants section.
+- One `<protect>` block wrapping the entire Workflow section (steps 1-8).
+- One `<protect>` block wrapping the Rules section.
+
+**Rationale**: Per-line tagging adds noise and makes files harder to
+maintain. Section-level tagging aligns with how DCP processes content
+(it compresses by sections, not by lines). A single block per logical
+unit keeps the markup clean.
+
+### D3: File-by-file protect coverage
+
+| File | Protected sections | Unprotected sections |
+|------|-------------------|---------------------|
+| forge.md | Critical Invariants, Workflow (1-8), Rules | Title, description, `$ARGUMENTS` placeholder |
+| handoff.md | Workflow (steps 0-5 with ordering constraint and handoff note structure) | Title, description |
+| inbox.md | Workflow (3 steps) | Title, description, Filtering, Sending |
+| forge-status.md | Workflow (3 steps) | Title, description, Interpreting Results, Quick Health Check |
+| org.md | Common Actions, Sessions | Title, description, Usage, Epics |
+
+### D4: DCP configuration
+
+**Decision**: Add `"protectTags": true` to the top level of
+`opencode.json`.
+
+**Rationale**: This is the toggle that tells OpenCode's DCP engine to
+recognize `<protect>` tags. Without it, the tags are ignored. The
+setting belongs in the project config so it applies to all agents using
+this repository.
+
+## Risks / Trade-offs
+
+### R1: Over-protection reduces DCP effectiveness
+
+If too much content is protected, DCP cannot compress enough and the
+conversation may hit context limits sooner. **Mitigation**: The design
+limits protection to behavioral content only -- roughly 60-70% of
+forge.md and handoff.md, 30-40% of the smaller files.
+
+### R2: Tag maintenance burden
+
+Future edits to command files must maintain `<protect>` tag placement.
+**Mitigation**: The tag pattern is simple (`<protect>` / `</protect>`)
+and the files are small (24-52 lines each). The tags are visually
+obvious during editing.
+
+### R3: Tags visible in non-DCP contexts
+
+Agents reading command files outside OpenCode's DCP engine will see the
+`<protect>` tags as literal text. **Mitigation**: The tags are inert
+HTML-style markup. They do not interfere with markdown rendering or
+agent comprehension. This aligns with the Composability First principle.

+## Why
+
+OpenCode's Dynamic Context Protocol (DCP) compresses user-message content
+during long conversations to stay within context limits. Slash command
+files (`internal/agentkit/content/commands/*.md`) are delivered as user
+messages, making them eligible for compression. When DCP compresses these
+files, critical instructions -- execution order, safety invariants,
+mandatory review gates -- can be lost or summarized, causing agents to
+skip steps or violate workflow constraints.
+
+DCP supports `<protect>` tags that mark content as compression-resistant.
+Content inside `<protect>` blocks is preserved verbatim during
+compression. This change adds `<protect>` tags to the five slash command
+files, targeting the content whose loss would cause behavioral failures.
+
+Prior work (forge-dcp-hardening, harden-forge-skill-compression,
+harden-skill-compression) restructured content for better DCP survival
+through positioning and constraint language. This change uses `<protect>`
+tags -- a complementary mechanism that explicitly marks content as
+non-compressible.
+
+Resolves: unbound-force/replicator#74
+
+## What Changes
+
+Add `<protect>` tags to five slash command files in
+`internal/agentkit/content/commands/`:
+
+1. **forge.md** -- Protect the Critical Invariants section (review gate
+   rules) and the ordered Workflow steps (1-8). The Rules section
+   reiterates invariants and should also be protected.
+2. **handoff.md** -- Protect the sequential workflow steps (0-5) and the
+   ordering constraint ("Steps MUST execute in this exact order").
+3. **inbox.md** -- Protect the 3-step Workflow section.
+4. **forge-status.md** -- Protect the 3-step Workflow section.
+5. **org.md** -- Protect the Common Actions tool reference and the
+   Sessions section (session start/end is critical for handoff
+   continuity).
+
+Additionally, enable `protectTags: true` in the DCP configuration
+(`opencode.json`) so that the tags are recognized by the compression
+engine.
+
+## Capabilities
+
+### New Capabilities
+- `dcp-protect-tags`: Slash command guardrails, workflows, and safety
+  rules survive DCP compression intact via `<protect>` tag markup.
+
+### Modified Capabilities
+- `forge-command`: Critical invariants and workflow steps are now
+  compression-resistant.
+- `handoff-command`: Sequential workflow steps are now
+  compression-resistant.
+- `inbox-command`: Workflow steps are now compression-resistant.
+- `forge-status-command`: Workflow steps are now compression-resistant.
+- `org-command`: Tool reference and session instructions are now
+  compression-resistant.
+
+### Removed Capabilities
+- None.
+
+## Impact
+
+- **Files modified**: 5 command markdown files under
+  `internal/agentkit/content/commands/`, plus `opencode.json` for DCP
+  config.
+- **No Go code changes**: The `<protect>` tags are consumed by
+  OpenCode's DCP engine, not by replicator's Go code. The agentkit
+  embeds these files as-is.
+- **No test changes**: The embedded content is delivered verbatim. Tags
+  do not affect tool registration or MCP protocol behavior.
+- **Risk**: Low. `<protect>` tags are inert markup when DCP is not
+  active or when `protectTags` is disabled. The tags have no effect on
+  agents that read the content directly.
+
+## Constitution Alignment
+
+Assessed against the Unbound Force org constitution.
+
+### I. Autonomous Collaboration
+
+**Assessment**: PASS
+
+This change strengthens autonomous collaboration by ensuring that
+workflow instructions agents rely on survive context compression. Agents
+following slash command workflows (forge coordination, handoff sequences)
+will receive the complete instructions regardless of conversation length.
+No runtime coupling is introduced.
+
+### II. Composability First
+
+**Assessment**: PASS
+
+The `<protect>` tags are inert when DCP is not active. The replicator
+binary remains independently installable and usable without OpenCode's
+DCP engine. The tags degrade gracefully -- they appear as no-op markup
+in non-DCP contexts.
+
+### III. Observable Quality
+
+**Assessment**: N/A
+
+This change modifies embedded markdown content, not tool outputs or
+machine-parseable artifacts. No observable output formats are affected.
+
+### IV. Testability
+
+**Assessment**: PASS
+
+The change is purely additive markup in embedded files. No test isolation
+requirements are affected. The embedded files can be verified by
+inspecting their content directly. No external services are required.
