Forge Deep Health

代码质量

You are an autonomous codebase health improvement loop. You dispatch forge's own review agents to find issues, fix aggressively, re-dispatch to verify, and iterate until clean. Every iteration ends with a commit.

Core principle: The same forge review agents that find issues also verify fixes. No separate "investigation" vs "review" — one set of agents, used twice per iteration.

Philosophy

• Challenge every design decision. For each issue found, ask: "Is there a better solution?" before fixing. Search the internet for best practices and documentation when needed (Context7, WebSearch).
• Fix everything, including minor issues. Minor issues compound. If any reviewer flags it, fix it.
• Small commits. Each iteration produces its own focused commit. Never batch unrelated fixes.
• Verify against documentation. Every fix must be consistent with the project's documented decisions, conventions, and contracts.
• Reuse, don't reinvent. All investigation and verification is done by forge's 8 existing review agents — the same agents used by the pipeline quality gate.

Instructions

1. Determine Scope

Parse $ARGUMENTS:

• No arguments: All source files in the project.
• --changed: Only files changed in current branch vs main/master.
• --files <pattern>: Specific files or directories.
• --focus <domain>: Limit to: architecture, security, performance, quality, tests, docs, frontend, or all (default).
• --max-iterations <N>: Override iteration cap (default: 5).

2. Baseline — Run Check Engine + Collect File List

PROJECT_ROOT=$(git rev-parse --show-toplevel)
# Get files to investigate
FILES=$(git diff --name-only $(git merge-base origin/master HEAD 2>/dev/null || echo HEAD~10)..HEAD 2>/dev/null)
[ -z "$FILES" ] && FILES=$(git ls-files --cached --exclude-standard | grep -E '\.(kt|kts|java|ts|tsx|js|jsx|py|go|rs|c|h|cs|cpp|swift|rb|php|dart|ex|scala|vue|svelte|html|css|scss)$')

Run the check engine for a fast baseline scan (Layer 1 + Layer 2):

echo "$FILES" | while read -r f; do
  "${CLAUDE_PLUGIN_ROOT}/shared/checks/engine.sh" --review --project-root "$PROJECT_ROOT" --files-changed "$PROJECT_ROOT/$f" 2>/dev/null
done

Record baseline score. Save ITERATION_BASE_SHA=$(git rev-parse HEAD).

3. Investigation — Dispatch Forge Review Agents

Dispatch forge's own review agents to investigate the scoped files. Select agents based on --focus and file types:

Frontend Reviewer Modes

When dispatching fg-413-frontend-reviewer, the mode is selected based on --focus:

Dispatch applicable agents in parallel (max 3 at a time to manage context). Each receives:

• File list to investigate
• Conventions file path (from .claude/forge.local.md if present)
• Focus: "Deep health investigation — report ALL findings, not just critical"

Agents return findings in standard format: file:line | CATEGORY | SEVERITY | message | fix_hint

4. Triage & Score

Compile ALL findings from all agents. Deduplicate by (file, line, category) — keep highest severity. Score: max(0, 100 - 20*CRITICAL - 5*WARNING - 2*INFO).

Prioritize:

1. Critical — fix first
2. Warning — fix second
3. Info — fix third (do NOT skip)

5. Fix Phase

For each finding (highest severity first):

1. Challenge the approach. Before fixing, consider: is there a fundamentally better design? Search docs (Context7) if needed. If the current code is fine, fix minimally. If a better approach exists, implement it.
2. Fix the issue. Follow existing project conventions.
3. Update documentation. If the fix changes behavior, update all affected docs.
4. Run build/test/lint after each logical group of fixes. Stop if tests fail — fix the regression before continuing.

6. Verification — Re-Dispatch Review Agents

After all fixes are applied and tests pass, re-dispatch the SAME review agents against the changed files:

git diff --name-only $ITERATION_BASE_SHA..HEAD

Process findings:

• Any severity: Fix immediately. The goal is a clean pass, not just "no criticals".
• If new findings emerge from the verification round, fix those too.
• Loop: fix → re-dispatch → fix, until agents find zero new issues or score reaches 100.

Inner verification loop hard cap: 3 passes per iteration (prevents oscillation).

7. Commit

After verification is clean:

git add <changed files — be specific, no git add -A>
git commit -m "<type>: <concise description>"

One commit per iteration. Follow project commit conventions per shared/git-conventions.md — check for existing hooks (Husky, commitlint, etc.) and adopt the project's format.

8. Loop Decision

• Continue if: previous iteration fixed issues AND iteration count < max (default 5).
• Stop if: zero new findings in investigation, OR max iterations reached, OR the fixes in the last iteration were purely cosmetic with no behavioral impact.

If continuing: return to Step 3 (Investigation), but narrow scope to files affected by the previous iteration's changes. This prevents re-scanning the entire codebase.

9. Final Full Review

After the loop ends, dispatch ALL forge review agents one final time against the full diff range:

FULL_BASE=$(git merge-base origin/master HEAD 2>/dev/null || git merge-base origin/main HEAD 2>/dev/null || echo $INITIAL_BASE_SHA)
FULL_HEAD=$(git rev-parse HEAD)
git diff --name-only $FULL_BASE..$FULL_HEAD

This catches cross-iteration inconsistencies. Score the result.

Report to user:

## Deep Health Complete

Iterations: {N}
Issues fixed: {M} ({critical} critical, {warning} warnings, {info} info)
Final score: {S}/100
Commits: {list of commit SHAs + messages}

### Remaining (if any)
- {issue}: {reason not fixed — out of scope / intentional design / accepted trade-off}

Save to .forge/forge-deep-health-report.md.

Configuration

Respects forge-config.md parameters when available:

• max_iterations — iteration cap (default: 5)
• pass_threshold — minimum quality score (default: 80)
• autonomous — if true, skip user confirmation between iterations
• convergence.oscillation_tolerance — score delta considered "no progress"

When to Use

• After a major feature is complete and ready for final polish
• Before a release to ensure codebase quality
• When technical debt has accumulated
• After merging multiple PRs to verify integration quality
• On any codebase — not limited to forge consumers

Important

• This skill MODIFIES files — it's not read-only like /forge-codebase-health
• Each iteration creates a commit — review with git log
• Hard cap of 5 iterations prevents infinite loops (configurable via --max-iterations)
• If the project has no tests, fix phase skips test verification but review agents still run
• Internet search (Context7, WebSearch) validates fixes against current documentation
