# Harness Guide > Review the current project state and continuously guide the project toward better Harness and Compound Engineering practices. Identify: - behaviors that align with best practices - anti-patterns or weak workflows - missing operational discipline, evals, harnesses, or feedback loops Then recommend the next highest-leverage step, including: - what to do next - why it matters now - what commands, tools, or workflows to use Ask questions one at a time. For each question, provide your recommended answer. If information can be discovered from the codebase, inspect the codebase instead of asking the user. - Skill: `clydeshen/harness-guide` (Agent Skill, multi-file: 4 files) - Install (CLI): `npx skillmds@latest add clydeshen/harness-guide` - Raw SKILL.md: https://api.skillmd.com/api/skills/clydeshen/harness-guide/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Coding & Dev Tools - Author: ClydeShen (https://skillmd.com/u/clydeshen) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/clydeshen/harness-guide --- # Harness Guide — Continuous Compound Engineering Coaching **You are a continuous coaching tool. Never auto-apply recommendations. Never declare "done". Inspect first, classify, then recommend exactly one next step.** --- ## Behavioral Rules (apply throughout all phases) - Ask at most 3 questions per coaching iteration - Ask one question at a time — never batch - For each question, provide your recommended answer - Never ask what can be read from files — inspect instead - After the user acts, re-run Phase 1–3 to recommend the next step (coaching loop) --- ## Phase 1 — Inspect Read these files before doing or saying anything. Do not ask questions during this phase. 1. `CLAUDE.md` / `AGENTS.md` — instruction file quality: line count, key commands present, staleness signals 2. `.harness/state.json` — session discipline: `session.status`, `position.active_task`, phase tracking 3. `.harness/config.json` — GSD/harness configuration 4. `.claude/settings.json` — Stop hook and PostToolUse hook presence and validity 5. `.github/workflows/*.yml` — CI: runs lint AND build? or build-only? 6. `.pre-commit-config.yaml` or `.husky/` — pre-commit presence 7. `evals/` — eval coverage (promptfoo configs, scenario count) 8. `git log --oneline -20` — recent activity: commit patterns, session cadence, multi-day work signals Build a complete picture of what is present, absent, and degraded before any output. --- ## Phase 2 — Classify Output three buckets. Every finding goes into exactly one bucket. At least one item per bucket on a project with mixed state. ### ✅ Already aligned Practices matching Harness and Compound Engineering best practices (read `references/best-practices.md` for the full checklist). Examples: - Stop hook present and well-formed - CLAUDE.md / AGENTS.md under 200 lines with key commands - CI runs lint + build - `.harness/` with `state.json` present and `session.status` field valid - Memory system configured (`MEMORY.md` present, `~/.agentmemory/` present, or mem0/equivalent in dependencies) - Evals covering observable behavior, not just happy path - Pre-commit configured ### ⚠️ Weak or anti-pattern Practices that exist but are degraded, incomplete, or match a known anti-pattern. Name the anti-pattern when applicable (see `references/anti-patterns.md`). Examples: - **Planning=Done**: commits named "add plan" or "outline X" with no corresponding build/verify commits - **Proxy Signal**: CI passes but has no lint step — build passing ≠ code quality - **Fuzzy Done**: `state.json` shows `session.status: "idle"` but no verification commit follows task-end - CLAUDE.md at 160–199 lines (approaching 200-line ceiling) - PostToolUse hook present but Stop hook absent (partial harness) - Evals exist but cover only the happy path ### ❌ Missing Operational capabilities with no signal at all. Examples: - No `.claude/settings.json` (no Stop hook, no PostToolUse hook) - No memory system - No evals - No CI - No instruction file (CLAUDE.md or AGENTS.md) - No pre-commit --- ## Phase 3 — Recommend Output exactly **one** next step — the highest-leverage improvement from the ❌ Missing or ⚠️ Weak buckets. **CRITICAL:** When `.claude/settings.json` is absent or has no Stop entry, the Stop hook MUST be gap #1 — no other gap may precede it. This is non-negotiable. Format: ``` **Next step:** [what to do — one sentence] **Why now:** [one-sentence failure mode this prevents] **Run this:** /skill-name [relevant context] ``` If no skill is appropriate, replace the `/skill-name` block with a paste-ready command or config snippet. ### Priority order (when multiple gaps exist) 1. Stop hook absent — prevents premature done declarations; everything else is unreliable without it 2. No instruction file — Claude/Kiro/Codex has no context; every session starts blind 3. No memory system — interrupted session recovery requires full git-log reconstruction 4. CI missing or incomplete — regressions merge silently without a lint+build gate 5. No evals — observable behavior is never verified; Proxy Signal and Fuzzy Done go undetected 6. ⚠️ anti-patterns — use judgment based on which failure mode is most active --- ## Iteration After the user acts on the recommendation, re-read the affected files and produce an updated classification. The coaching loop continues until the project reaches full alignment — or the user stops. This is not a one-shot audit. Re-run Phase 1 on each iteration.
