Execute Review Findings

Execute Review Findings

Systematically convert review findings into tracked tasks and execute them in priority waves with parallel agents where files don't overlap.

Core principle: Normalize findings → create self-contained beads tasks → analyze concurrency → execute in priority waves with parallel dispatch.

When to Use

• After /review-dispatch produces a ranked findings report
• After receiving multiple PR review comments
• When handed an ad-hoc review document (security audit, perf report, etc.)
• When a review produced 3+ findings that span multiple files

When NOT to Use

• Single finding — just fix it directly
• Findings are all in the same function — no parallelism benefit
• You haven't read the code yet — understand first, then act

Invocation

/execute-review-findings <source>

Source options:

• pr or pr:<number> — fetch PR comments via gh api
• review — use the most recent /review-dispatch output in conversation
• <file-path> — read a markdown review document from disk
• (no argument) — prompt user to paste or describe findings

Phase 1: Gather & Normalize

Parse findings from any source into a uniform list. Each normalized finding has:

Parsing rules by source:

• /review-dispatch output: Parse the ranked tables directly. Map importance 9-10 → CRITICAL, 7-8 → SHOULD FIX, 5-6 → CONSIDER, 1-4 → NIT.
• PR comments: Fetch via gh api repos/{owner}/{repo}/pulls/{number}/comments. Categorize each: bug claim → bug type, style suggestion → design/complexity, question → skip (reply only).
• Markdown document: Look for severity markers, tables, or heading-based grouping. Map to standard severities.

Severity Normalization

Reviewers use different severity vocabularies. Normalize all external labels to the four canonical levels before filtering:

When a finding lacks an explicit severity label, infer from type:

• Bug → default SHOULD FIX (unless clearly cosmetic)
• Safety / Security → default CRITICAL
• Performance → default SHOULD FIX
• Documentation / Design / Complexity → default CONSIDER

Present the normalized table to the user for confirmation before proceeding.

Severity Filter (Default: CRITICAL + SHOULD FIX + CONSIDER)

After normalization, discard NIT-severity findings by default. Only CRITICAL, SHOULD FIX, and CONSIDER proceed to Phase 2.

In reviewer terms: CRITICAL and HIGH are always addressed. MEDIUM is addressed (maps to CONSIDER). LOW, Minor, NIT, Trivial, Style, and INFO are skipped — these are cosmetic or informational and dilute agent focus.

Discarded findings are listed in the summary report (Phase 6) with status "Skipped (below threshold)".

Override: Use --include=nit to opt in to NIT-severity findings when the user explicitly wants them addressed.

Phase 2: Create Beads Tasks

Create one bd create per finding. Each task description must be fully self-contained — a fresh agent can work it without reading the original review.

Task Description Template (All Types)

## Finding: {summary}

**Severity**: {severity}
**File(s)**: {file}:{line}
**Type**: {type}
**Flagged by**: {specialists}

### Problem
{detail — full finding including current behavior and why it matters}

### Resolution Steps
{type-specific steps — see below}

### Acceptance Criteria
- [ ] {specific, verifiable conditions}
- [ ] All existing tests pass: `cargo test`
- [ ] Code compiles clean: `cargo fmt --all && cargo check && cargo clippy --all-targets --all-features -- -D warnings`

Type-Specific Resolution Steps

Bug (TDD mandatory + test-consolidate):

1. Analyze existing tests using /test-consolidate principles BEFORE writing any test:
   a. Read the test module for the affected file
   b. Identify existing test clusters that cover the same function/method
   c. Determine the right test form for the new test:
      - If existing tests for this function use rstest: ADD A NEW #[case] to the
        existing parameterized test rather than writing a standalone #[test]
      - If existing tests use proptest: check if the bug reveals a property violation
        — if so, tighten the property assertion rather than adding a separate test
      - If existing tests use table-driven: add the bug's input/expected to the table
      - If no existing tests or tests are standalone: write a new test, but prefer
        rstest #[case] format if 3+ similar tests already exist for the same function
   d. NEVER duplicate test structure that already exists — extend, don't clone
2. Write the failing test in the form determined by step 1
   - Test name: descriptive of the behavior, NOT the review
   - Place in the appropriate test module for the file
3. Run test, confirm it FAILS: `cargo test <test_name> -- --nocapture`
4. Fix the production code — minimal change to pass the test
5. Run full suite: `cargo test`
6. Verify clean: `cargo fmt --all && cargo check && cargo clippy --all-targets --all-features -- -D warnings`

Performance:

1. Establish baseline: run relevant benchmark or add one if none exists
   - Use `/bench-compare` if Criterion benchmarks cover this path
2. Implement the optimization
3. Re-benchmark and compare against baseline
4. Verify no regressions: `cargo test`
5. Verify clean: `cargo fmt --all && cargo check && cargo clippy --all-targets --all-features -- -D warnings`

Safety (unsafe code):

1. Write a test exercising the unsafe path with edge-case inputs
2. Fix the safety issue (bounds checks, invariant enforcement, etc.)
3. Add or update `// SAFETY:` comment documenting invariants
4. Run tests: `cargo test`
5. If Miri-compatible: `cargo +nightly miri test <test_name>`
6. Verify clean: `cargo fmt --all && cargo check && cargo clippy --all-targets --all-features -- -D warnings`

Documentation:

1. Read the code the docs describe — understand actual behavior
2. Write or update documentation to match reality
3. Check AGENTS.md consistency table — if touched file is listed, update corresponding docs
4. Verify doc tests compile: `cargo test --doc`
5. Verify clean: `cargo fmt --all && cargo check && cargo clippy --all-targets --all-features -- -D warnings`

Design / Complexity:

1. Read surrounding code to understand existing patterns
2. Refactor to address the finding while preserving behavior
3. Run full test suite to confirm no regressions: `cargo test`
4. Verify clean: `cargo fmt --all && cargo check && cargo clippy --all-targets --all-features -- -D warnings`

Priority Mapping for bd create

Example

bd create --title="Fix off-by-one in window boundary check" --type=bug --priority=1

Then update the description with the full self-contained template using bd update <id> --description="...".

Phase 3: Concurrency Analysis

Determine which tasks can run in parallel vs. must run sequentially.

Step 1: Build File-Touch Map

For each task, list every file it will read or write:

Step 2: Identify Conflicts

Two tasks conflict if they write to the same file. Read-read and read-write of different files are fine.

Step 3: Form Parallel Groups

Within each severity wave, group non-conflicting tasks:

Wave 1 (CRITICAL):
  Group A (parallel): F1, F4  — no file overlap
  Group B (sequential after A): F3  — conflicts with F1 on core.rs

Wave 2 (SHOULD FIX):
  Group C (parallel): F5, F6, F7  — no file overlap

Step 4: Register Dependencies

bd dep add <F3-id> <F1-id>   # F3 depends on F1 (same file)

Phase 4: Execute in Priority Waves

Execute findings wave by wave: CRITICAL → SHOULD FIX → CONSIDER. NIT and INFO findings are skipped by default (see Phase 1 severity filter).

Within Each Wave

1. Dispatch parallel agents for each non-conflicting group using the Task tool with subagent_type=general-purpose. Each agent gets the full self-contained task description from Phase 2.

2. Agent prompt structure:

   You are fixing a code review finding. Follow the resolution steps exactly.
   
   {full task description from Phase 2}
   
   IMPORTANT:
   - Follow the resolution steps in order
   - For bugs: BEFORE writing any test, read the existing test module and apply
     /test-consolidate principles:
     * If the function already has rstest parameterized tests, add a #[case] — do NOT
       create a new standalone test function
     * If the function has proptest coverage, tighten the property or add a targeted
       prop_assert — do NOT duplicate with a unit test
     * If similar tests exist as a table-driven loop, add your case to the table
     * Only create a new standalone #[test] when no consolidation opportunity exists
     * NEVER create a test that duplicates coverage already provided by existing tests
   - For bugs: write the failing test BEFORE fixing code
   - Run all verification commands listed in acceptance criteria
   - Report back: what you changed, test results, any issues encountered
   

3. Collect results from all agents in the group.

4. Sequential groups: After a parallel group completes, dispatch the next group that depended on it.

5. Close completed tasks: bd close <id> for each successfully resolved finding.

Quality Gate Between Waves

Before moving to the next wave, run:

cargo fmt --all && cargo check && cargo clippy --all-targets --all-features -- -D warnings
cargo test

If anything fails, fix it before proceeding. Do not let failures from Wave 1 propagate into Wave 2.

Handling --plan-only Mode

If invoked with --plan-only, stop after Phase 3. Present the task list, dependency graph, and execution plan without dispatching agents. The user can then:

• Reorder or remove tasks
• Adjust groupings
• Execute manually or re-invoke without --plan-only

Phase 5: Doc Verification

After all waves pass the quality gate, dispatch a separate /doc-verify agent on every source file modified during execution. This catches documentation drift introduced by the fixes.

Step 1: Collect Modified Files

Gather the list of all .rs files that were modified across all waves. Use git diff --name-only (unstaged) to identify them. Filter to .rs files only — skip test-only files and Cargo.toml.

Step 2: Dispatch Doc-Verify Agent

Launch a fresh Task agent with subagent_type="general-purpose". The agent prompt must:

1. Read every modified source file in full
2. Read adjacent module files for cross-reference context
3. Follow the /doc-verify Phase 2 verification protocol:
   • Extract all testable claims from doc comments
   • Verify each claim against the actual (now-modified) code
   • Classify findings as BLOCK / WARN / INFO
4. Produce the standard doc-verify report

You are a documentation verifier. You have zero prior context about why these files
were changed — verify only what the documentation says against what the code does.

Files to verify:
{list of modified .rs files}

Follow the /doc-verify Phase 2 protocol exactly:
- Step A: Extract all testable claims from doc comments
- Step B: Verify code-level claims against actual implementation
- Step C: Identify external claims
- Step D: Verify external claims (skip with --code-only if time-constrained)
- Step E: Produce findings report

Output the standard doc-verify report format with BLOCK/WARN/INFO findings.

Step 3: Handle Findings

• No BLOCKs: Proceed to summary report.
• BLOCKs found: Present findings to the user. Doc BLOCKs indicate the fixes introduced documentation inaccuracies (e.g., a doc comment now describes old behavior). These should be fixed before considering the review execution complete.
  • If the BLOCK is a trivial doc update (stale count, renamed parameter), fix it inline.
  • If the BLOCK requires judgment (rewriting a behavioral description), flag it for the user.

When to Skip

• If --skip-doc-verify flag is set, skip this phase entirely.
• If no modified files contain doc comments (verified via quick Grep for doc-comment prefixes), skip with a note in the summary.

Phase 6: Summary Report

After all waves complete, present:
