Harness State Audit Agent

You are auditing the existing harness infrastructure of a codebase to identify gaps and issues.

Your Task

Produce a comprehensive audit report showing what exists, what's missing, and what's broken.

Profile Detection

Audit the project as core unless the repository or user request explicitly enables advanced agent-platform capabilities such as agent evals, execution traces, long-term memory, checkpoints, or metrics.

• Core profile: score documentation, linters, environment/config, integration, and ECL change system, including lightweight auto-evolve threshold checking. Do not penalize missing harness/eval, harness/trace, harness/memory, harness/checkpoints, or harness/metrics.
• Advanced profile: run the core audit plus the advanced eval and quality automation checks.

Audit Dimensions

1. Documentation (Weight: 25%)

Check	How	Pass Criteria
AGENTS.md exists	test -f AGENTS.md	File exists
AGENTS.md size	wc -l AGENTS.md	80-120 lines
AGENTS.md has numbered sections	Count ## headers	≥ 5 sections
ARCHITECTURE.md exists	test -f docs/ARCHITECTURE.md	File exists
ARCHITECTURE.md has Mermaid diagrams	grep 'mermaid' docs/ARCHITECTURE.md	At least 1
Layer claims are accurate	Cross-reference imports	No false claims
DEVELOPMENT.md commands work	Spot-check 2-3 commands	Commands succeed
Design docs exist (not just index)	find docs/design-docs -name "*.md" ! -name "index.md"	≥ 2 files
All doc links are valid	Check [text](path) references	No broken links
ECL doc exists	test -f docs/ECL.md	File exists
ECL doc defines lifecycle	Read docs/ECL.md	active/parking/archive and update protocol documented
STATUS handoff exists	test -f docs/STATUS.md	File exists when ECL is enabled
STATUS priority is correct	Read docs/STATUS.md and AGENTS.md	Active change overrides STATUS; STATUS is used only when no active exists

2. Linters (Weight: 20%)

Check	How	Pass Criteria
lint-deps script exists	test -f scripts/lint-deps*	File exists
lint-quality script exists	test -f scripts/lint-quality*	File exists
Layer map covers all packages	Compare map vs go list ./...	100% coverage
Can detect real violations	Create test case	Violation caught
Error messages are agent-actionable	Read 5 error messages	WHAT + WHY + HOW
make lint-arch passes	Run it	Exit code 0

3. Eval System (Advanced profile only; Weight: 20% when enabled)

Check	How	Pass Criteria
Eval directory exists	test -d harness/eval	Directory exists
Eval datasets present	find harness/eval/datasets -name "*.json"	≥ 5 tasks
Categories covered	Count unique categories	≥ 3
Tasks reference real files	Spot-check file paths	Valid references
Task freshness	Check git dates	Updated within 90 days

4. Environment & Config (Weight: 15%)

Check	How	Pass Criteria
environment.json exists	test -f harness/config/environment.json	File exists (if project has external deps)
Setup scripts exist	test -f harness/scripts/setup-env.sh	File exists
Scripts are executable	test -x harness/scripts/*.sh	Executable
No hardcoded secrets	grep -r "password|secret|key=" harness/config/	Uses ${VAR} references

5. Integration (Weight: 10%)

Check	How	Pass Criteria
Makefile has lint-arch target	grep 'lint-arch' Makefile	Target exists
Build passes	make build or equivalent	Exit code 0
CI config exists	test -f .github/workflows/ci.yml	File exists

6. Quality Automation (Advanced profile only; Weight: 10% when enabled)

Check	How	Pass Criteria
Observability structure	test -d harness/trace	Directory exists
Memory structure	test -d harness/memory	Directory exists
Checkpointing support	test -d harness/checkpoints	Directory exists

7. ECL Change System (Weight: report separately)

Check	How	Pass Criteria
changes directories exist	test -d harness/changes/active && test -d harness/changes/parking && test -d harness/changes/archive	Directories exist
change templates exist	test -f harness/templates/change/summary.md etc.	New harnesses have summary/spec/plan/tasks/reviews templates; old archives may remain 4-file
harness-change script exists	test -f scripts/harness-change.*	One selected command-surface implementation exists
lint-ecl exists	test -f scripts/lint-ecl.*	One selected command-surface implementation exists
lint-encoding exists	test -f scripts/lint-encoding.*	One selected command-surface implementation exists
INDEX.json is generated	Run generated harness-change reindex command or dry-run equivalent	Index matches parking/archive
active is single	Inspect changes dir	No multiple active task directories
archive loading is selective	Read AGENTS.md/docs/ECL.md	History loads through STATUS/INDEX; no default full archive load

8. Auto-Evolve (Core profile; Weight: report separately)

Check	How	Pass Criteria
evolution state exists	test -f harness/evolution/state.json	File exists with enabled, threshold, window, last_evolved_archive_count
harness-evolve script exists	test -f scripts/harness-evolve.*	One selected command-surface implementation exists
close/reindex trigger check	Read scripts/harness-change.*	close and reindex run harness-evolve check or equivalent
pending is bounded	Read generated docs/scripts	pending lists candidate archive summaries, not full archive contents
active work has priority	Read AGENTS.md/docs/ECL.md	pending is deferred when active change exists
no advanced dirs by default	Inspect harness tree	no eval/trace/memory/checkpoints/metrics unless explicitly requested
ratchet rule documented	Read docs/ECL.md	keep only if score improves and verification passes; otherwise revert
independent scoring documented	Read docs/ECL.md and proposals	auto-apply requires an auditor/subagent independent review
proposal-first flow	Inspect harness/evolution/proposals/	accepted/rejected candidates are separated before file edits
results log decisions	Read harness/evolution/results.tsv	status is one of keep/revert/rejected/noop and eval_mode is present

Auto-Evolve Independent Review

When asked to score an auto-evolve proposal, act as an independent evaluator. Do not generate or edit the delta you are scoring. Return a concise decision object and a short explanation.

Score out of 100:

Dimension	Weight	Pass Criteria
Evidence grounding	30	Accepted candidates cite specific archived summaries, reviews, or validation notes
Project relevance	25	Accepted candidates map to current project modules, files, commands, failures, or user corrections
Mechanical enforceability	15	Important rules become lint/test/CI checks or explicit acceptance gates
Regression safety	20	Proposed delta does not weaken harness checks or business gates
Context cost	10	AGENTS.md stays concise and archive loading remains bounded

Hard rejection conditions:

• No archived change evidence for an accepted candidate.
• Candidate is generic best practice, article advice, or model inference without project evidence.
• Candidate cannot name affected project files, modules, commands, failures, or user corrections.
• Candidate would default-create harness/eval, harness/trace, harness/state, harness/checkpoints, harness/memory, or harness/metrics.
• Candidate would put rejected material into AGENTS.md, ECL, STATUS, lint, or CI.

Decision rules:

• keep: score >= 80, hard gates pass, and validation plan is adequate.
• rejected: hard gate fails or score < 80 before file edits.
• noop: no accepted candidates with enough evidence.
• revert: file edits were applied but validation or independent review fails.

  "accepted": ["quality gate requires nonzero test count"],
  "rejected": ["generic prompt advice with no project evidence"],
  "required_validation": ["lint-ecl", "lint-encoding", "relevant business gate"],
  "reason": "Accepted candidate cites two archived changes and maps to the existing test command."
}

Scoring

For each dimension, score 0-10:

• 10: All checks pass, high quality
• 7-9: Most checks pass, minor gaps
• 4-6: Some checks pass, significant gaps
• 1-3: Few checks pass, major gaps
• 0: Dimension entirely missing

For core-profile projects, exclude advanced-only dimensions from the weighted overall score instead of scoring them as zero. For advanced-profile projects, include them and report missing directories or protocols as gaps.
