Fix Loop

Fix Loop

Autonomous review-fix cycle that iterates until all critical issues are resolved.

The value of this skill is that it separates finding problems from fixing them. The code-reviewer agent operates read-only with a disconfirmation mindset — it actively looks for flaws. The fixer agent then applies minimal, targeted changes. This separation prevents the common failure mode where a fixer rationalises away problems it finds in code it's about to change.

Input

One of:

• File path(s) to review
• Directory to scan
• No argument — automatically determines scope

Execution

Step 1: Determine Scope

Determine which files to review, in priority order:

1. If the user specified files/directories, use those
2. If there are uncommitted changes: git diff --name-only (unstaged) + git diff --name-only --staged (staged)
3. If there are recent commits: git diff --name-only HEAD~3
4. If none of the above apply, ask the user what to review

Step 2: Baseline Test Check

Run devtool test before making any changes. Record the result — this is needed later to distinguish pre-existing failures from regressions introduced by fixes.

Step 3: Review-Fix Loop

Set iteration = 1 and scope = <initial files>.

LOOP while iteration <= 5:

Five iterations is the cap because experience shows that if critical findings persist beyond 3-4 cycles, the remaining issues typically need human judgement rather than automated fixing. The cap prevents wasted cycles.

1. REVIEW (iteration N) — Announce: Review iteration N/5

   • Spawn the code-reviewer agent with scope as its input
   • Receive the findings report

2. TRIAGE — Extract only Critical findings from the report

   • If zero critical findings, break — the loop is done
   • List the critical findings for visibility
   • Only critical findings are actioned because warnings and suggestions are judgement calls best left to the author. Automating fixes for subjective issues risks introducing changes the user disagrees with.

3. FIX (iteration N) — Announce: Fix iteration N/5 — addressing N critical issue(s)

   • Spawn the fixer agent, passing it:
     • The list of critical findings (with file paths and line numbers)
     • The review context
   • Receive the fix report (fixed, unfixable, files modified, test status)

4. NARROW SCOPE — Set scope to the files listed in the fixer's "Files Modified" output

   • If the fixer modified files not in the original scope, include those too — fixes can introduce issues in new files
   • If no files were modified (all findings were unfixable), break to the final report

5. INCREMENT — iteration += 1

END LOOP

Step 4: Final Report

Announce: Fix loop complete

# Fix Loop Report

## Iterations: N/5

## Resolved (Critical)
- [file:line] [issue] — fixed in iteration N

## Remaining (Critical)
- [file:line] [issue] — reason not fixed

## Noted (Warning / Suggestion)
- [file:line] [issue] — from iteration N (not actioned)

## Test Status
[Compare against baseline from Step 2. Report regressions vs pre-existing failures.]

Step 5: Commit

Ask the user: Commit these changes?

If yes, invoke commit-commands:commit.
