/dld-audit-auto — Autonomous Audit & Fix

You are running an autonomous audit of the decision-code relationship. Unlike the interactive /dld-audit, you detect issues and fix them without asking for human input. Your output is a branch with fixes and a PR for review.

This skill is designed for unattended execution — scheduled runs, CI pipelines, or autonomous agent sessions. Do not ask questions or wait for user input.

Script Paths

Shared scripts:

../dld-common/scripts/common.sh
../dld-common/scripts/regenerate-index.sh
../dld-common/scripts/update-status.sh

Skill-specific scripts:

../dld-audit/scripts/find-annotations.sh
../dld-audit/scripts/find-missing-amends.sh
../dld-audit/scripts/update-audit-state.sh

Prerequisites

1. Check that dld.config.yaml exists at the repo root. If not, exit with a clear error message.
2. Verify the working tree is clean (git status --porcelain should be empty). If not, exit — do not mix audit fixes with uncommitted work.

Step 1: Create audit branch

git checkout -b dld/audit-$(date +%Y%m%d-%H%M%S)

Step 2: Run the full audit

Perform all the same checks as /dld-audit:

a) Collect annotations and decision records

bash ../dld-audit/scripts/find-annotations.sh

Read all DL-*.md files in the records subdirectory (decisions/records/). Note each decision's ID, status, and code references.

b) Detect issues

Check for all drift categories:

1. Orphaned annotations — annotations referencing non-existent decision IDs
2. Annotations referencing non-accepted decisions — code tied to deprecated or superseded decisions
3. Stale references in decisions — frontmatter references to files that no longer exist
4. Unreferenced code changes — annotated files modified since last audit (if previous audit state exists)
5. Decisions without annotations — accepted decisions with code references but no corresponding annotations in code
6. Missing amendment relationships — decisions whose body references modifying part of a previous decision but have an empty amends field

For check (4), if decisions/.dld-state.yaml exists with an audit.commit_hash, first verify reachability:

git cat-file -t <commit_hash> 2>/dev/null

If unreachable (e.g., after rebase or shallow clone), skip check (4) and note it in the PR description. If reachable, use git diff --name-only <commit_hash>..HEAD to find changed files and cross-reference with annotated files.

Step 3: Fix issues

Apply fixes for each issue category. Use judgment on what can be safely fixed automatically vs. what should only be flagged in the PR description.

Hard rule: never edit the body of an accepted decision

The narrative body of an accepted decision (Context, Decision, Rationale, Consequences, and any other prose sections) is immutable. An audit must never rewrite, refine, "clean up", or otherwise modify it.

The only changes an audit may make to an accepted decision are housekeeping updates to specific frontmatter fields — references, amends, superseded_by, and similar relational metadata — plus adding or fixing @decision annotations in code.

If drift suggests the substance of an accepted decision is no longer accurate, or that code has evolved beyond what the decision describes, do not modify the original record. Instead, create a new decision (status accepted, since the code already exists) that captures the new rationale and uses supersedes or amends to link back to the prior one. The original stays as-is to preserve the historical record of why things were done that way at the time.

Auto-fixable (apply these directly):

Orphaned annotations — If the annotation has an obvious typo (e.g., DL-01 where DL-001 exists), fix it. If the referenced ID is completely unknown, remove the annotation and note the removal in the commit message.

Stale references in decisions — Remove file paths from the decision's references field that no longer exist. If the file was renamed/moved (detectable via git log --follow --diff-filter=R), update the path instead of removing.

Annotations referencing superseded decisions — Update the annotation to reference the superseding decision (read the supersedes field of the newer decision to find the chain). For deprecated decisions, remove the annotation.

Annotations referencing amended decisions — Do not rewrite or remove these annotations. The original decision is still active. Instead, note the amendment relationship in the PR description so reviewers can verify the code aligns with the amendment.

Missing amendment relationships — Run bash ../dld-audit/scripts/find-missing-amends.sh to get candidates. The script only emits candidates whose source decision changed since the last audit, so re-runs stay focused on new work. For each candidate, read the source decision's body and determine if it describes a partial modification. If so, add the referenced ID to the amends field. Flag prominently in the PR for review, since this is an inferred relationship.

Decisions without annotations — If an accepted decision has code references but no annotations, and the referenced files exist, add the missing @decision(DL-NNN) annotations to the referenced code locations.

Best-effort fixes (apply, but flag prominently for review):

Unreferenced code changes — Annotated files that were modified since the last audit without a corresponding decision update. These represent changes made outside the DLD process. Try to resolve them:

1. Check commit messages — Read the commits that modified the file (git log --oneline <last_audit_hash>..HEAD -- <file>). Look for context about what changed and why.
2. Look up referenced tickets — If commit messages reference a ticket (e.g., Jira, Linear, GitHub issue), try to look it up using available tools (MCP servers, gh CLI, etc.) to gather additional context about the change.
3. Assess the impact — Read the current code and the associated decision(s). Determine whether:
   • The existing decision is still accurate (the change was compatible — no action needed)
   • The change introduced new or different behavior/rationale that is not fully captured by the existing decision (a new decision is needed)
4. Create a new decision when needed — Per the hard rule above, never edit the body of the existing accepted decision to absorb the new behavior. Instead, create a new decision using the standard scripts, mark it accepted (the code already exists), and link it to the prior decision via supersedes or amends as appropriate. Add @decision annotations to the new/changed code pointing at the new decision.

Important: These best-effort fixes are inferred, not authoritative. In the PR description, clearly mark each one under a "Inferred Decisions — Review Required" section. Explain what changed, what context was found (commit messages, tickets), and what new decision was created. Reviewers should prioritize checking these for accuracy.

Step 4: Regenerate INDEX.md

If any decision records were modified:

bash ../dld-common/scripts/regenerate-index.sh

Step 5: Update audit state

bash ../dld-audit/scripts/update-audit-state.sh

Step 6: Commit, push, and open PR

If there are changes (fixes were applied or audit state was updated):

git add -A

Commit with a descriptive message summarizing the fixes:

git commit -m "fix: resolve DLD audit drift

- [list each fix applied]
- Audit state updated"

Push and open a PR:

git push -u origin HEAD

Create a PR with the following structure:

## DLD Audit — Automated Drift Fixes

**Audit date:** YYYY-MM-DD
**Issues found:** N
**Auto-fixed:** M
**Needs review:** K

### Fixes Applied

- [Description of each fix, grouped by category]

### Inferred Decisions — Review Required

These decisions were created or updated based on code changes made outside the DLD process. The rationale was inferred from commit messages and available ticket context. **Please verify accuracy.**

- **DL-NNN: [Title]** (new/updated) — [What changed in the code, what context was found, what was inferred]

### Audit Summary

| Check | Result |
|-------|--------|
| Orphaned annotations | N found, M fixed |
| Stale references | N found, M fixed |
| Superseded/deprecated refs | N found, M fixed |
| Missing annotations | N found, M added |
| Modified annotated files | N flagged for review |

If no issues were found (only audit state updated), still commit and push the state update but do not open a PR. Instead, exit with a message:

Audit complete. No drift detected. Audit state updated.
