Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00043 | $0.01200 |
| Opus 5.5 | $0.00017 | $0.00480 |
| Sonnet 5.5 | $0.00009 | $0.00240 |
| Haiku 4.5 | $0.00004 | $0.00120 |
Grade A, and why
harness-setup scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 139 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Harness Setup
Analyze your project and generate a production-ready Claude Code harness. Works for any stack — reads your actual code instead of filling templates.
When to Use
- Project missing a CLAUDE.md, or existing one is generic/outdated
- Need settings.json with balanced permission rules
- Want validate-command.py + protect-files.py safety hooks
Step 0: Check for Existing CLAUDE.md
If CLAUDE.md exists and has content:
Ask: "Found existing CLAUDE.md. Overwrite with new harness, or skip?"
- Skip → stop
- Overwrite → continue
Step 1: Deep Project Scan (parallel reads)
Read references/analysis-guide.md for extraction instructions. Then run all reads simultaneously.
Read whichever of these exist:
- Root config files:
package.json,pom.xml,pyproject.toml,go.mod,Cargo.toml,composer.json,Gemfile,build.gradle Makefile(if exists).env.example(if exists)- Directory structure: glob
**to depth 2 - One representative source file (entry point or a typical service/controller)
- One test file (look in
tests/,test/,spec/,src/test/,__tests__/)
After reading, extract answers to:
| Question | Source |
|---|---|
| Stack | Config files + deps (see analysis-guide.md §Stack Identification) |
| Run/build/test/lint commands | scripts in package.json, Makefile targets, pom.xml goals |
| Directory structure | Glob result — top 3–5 meaningful dirs |
| ORM/database | Deps + schema file location |
| Env vars needed | .env.example or grep process.env./os.getenv( in source |
| Test framework + location | Test file imports + directory name |
| Package manager | Lockfile presence: bun.lockb→bun, pnpm-lock.yaml→pnpm, yarn.lock→yarn, else npm |
| Port | Dev script, application.properties:server.port, or stack default |

What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

harness-setup is a skill published in the GitHub repository ShipWithAI/shipwithai-plugins (9 stars, last pushed 2mo ago), licensed MIT. It adds 43 tokens to every session and 1,200 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
