Owner

Summary

Updates the §Prompt Injection Mitigation section in docs/specification.md to use XML-delimited tags as the canonical approach, replacing the [USER_CONTENT_START]/[USER_CONTENT_END] bracket markers.

Changes

§Prompt Injection Mitigation

  • Replaces [USER_CONTENT_START]/[USER_CONTENT_END] markers with XML-delimited tags (e.g., <user_content>...</user_content>)
  • Documents the sanitization requirement: escape <, >, & before embedding user content
  • Notes that XML tags prevent injection via forged closing tags when combined with proper sanitization
  • Cross-references _sanitize_xml_content() as the reference implementation pattern

Motivation

The implementation (merged in commit d3cb534c, PR #1175) uses XML-delimited tags for prompt injection mitigation, explicitly documented as a deviation from the spec with rationale that the XML approach is more structured. This PR updates the spec to match the implementation.

Replace [USER_CONTENT_START]/[USER_CONTENT_END] bracket markers with XML-delimited tags as the canonical approach for prompt injection mitigation in the Strategize phase.

Document the sanitization requirement: escape <, >, & before embedding user content in XML-delimited sections. Note that XML tags prevent injection via forged closing tags when combined with proper sanitization.

Cross-reference _sanitize_xml_content() as the reference implementation.

Closes #9522

Code Review: REQUEST CHANGES

Summary

This PR updates docs/specification.md to replace [USER_CONTENT_START]/[USER_CONTENT_END] bracket markers with XML-delimited tags for prompt injection mitigation. The content change itself is correct and well-written. However, several process/compliance requirements from CONTRIBUTING.md are not met.


What Looks Good

  1. CI passes — All CI checks passed (run #18313).
  2. Content correctness — The spec change accurately reflects the implementation (commit d3cb534c, PR #1175). The new text correctly documents:
    • XML-delimited tags as the canonical approach
    • The sanitization requirement (escaping <, >, &)
    • Cross-reference to _sanitize_xml_content() as the reference implementation
    • Prevention of injection via forged closing tags
  3. Commit message formatdocs(spec): ... follows Conventional Changelog type(scope) format.
  4. PR description — Detailed and well-structured with motivation and related issue.
  5. Closes keywordCloses #9522 is present in the PR body.

Issues Requiring Changes

1. Missing Milestone Assignment

The PR has no milestone assigned. The linked issue #9522 is assigned to v3.2.0, and the triage comment explicitly states "Should Have for v3.2.0". The PR must be assigned to the v3.2.0 milestone.

2. Missing Type/ Label

The PR only has the Needs Feedback label. Per CONTRIBUTING.md, every PR must have exactly one Type/ label. For a pure documentation change, Type/Documentation should be applied.

3. Missing Changelog Update

CONTRIBUTING.md requires a changelog update for PRs. No changelog file was modified in this PR (only docs/specification.md was changed).

4. Missing CONTRIBUTORS.md Entry

CONTRIBUTING.md requires a CONTRIBUTORS.md entry for each PR. This file was not updated.

5. Commit Message: Missing ISSUES CLOSED: Format

The commit body uses Closes #9522 but CONTRIBUTING.md specifies the format should be ISSUES CLOSED: #N in the commit body. Please update the commit message to include:

ISSUES CLOSED: #9522

6. Incomplete Acceptance Criteria — Other Occurrences Not Checked

Issue #9522 acceptance criteria includes: "Any other spec sections referencing [USER_CONTENT_START]/[USER_CONTENT_END] are updated for consistency." The diff only shows 1 line changed. Please verify there are no other occurrences of [USER_CONTENT_START] or [USER_CONTENT_END] remaining in docs/specification.md and confirm this in the PR description.


Required Actions

  • Assign milestone v3.2.0 to this PR
  • Add Type/Documentation label
  • Add changelog entry
  • Add CONTRIBUTORS.md entry
  • Update commit message to use ISSUES CLOSED: #9522 format
  • Verify and confirm no other occurrences of [USER_CONTENT_START]/[USER_CONTENT_END] remain in the spec

[GROOMED] Quality analysis complete.

Checks Performed

  • Labels: Required Type/Documentation, State/In Review, Priority/Medium, and MoSCoW/Should have are still missing. Multiple forgejo-label-manager attempts failed because the environment lacks the approved label-write tool, so manual application is still needed.
  • Milestone: Assigned to v3.2.0 to match the linked issue.
  • Reviews: HAL9001 review (ID 5786) remains in REQUEST_CHANGES status.
  • Linked issues: Issue #9522 remains open and referenced via the PR description (Closes #9522).

Fixes Applied

  • Added milestone v3.2.0.

Remaining Issues (Require PR Author Action)

  • Apply the required labels (Type/Documentation, State/In Review, Priority/Medium, MoSCoW/Should have) alongside the existing Needs Feedback label.
  • Add the missing changelog update referenced in the review.
  • Add the CONTRIBUTORS.md entry requested in the review.
  • Update the commit message format to include "ISSUES CLOSED: #9522".
  • Respond to HAL9001's acceptance-criteria questions and provide any outstanding verification or testing evidence.
