Why use it?
It keeps project work consistent by directing agents to the correct procedure for each task and documenting the repository's branch rules.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions .claude-plugin; mentions Claude Code.

This is 0x0w1/jig's own configuration. It tells Claude Code how to work on jig itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything jig configures →

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

jig CLAUDE.md 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 1mo 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.

Origin

This is a copy

94% identical to jig AGENTS.md — 47 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Claude Code Rules

Use these repo-scoped Claude Code skills:

  • Repository setup/sync: github-sync from .claude/skills/github-sync/SKILL.md.
  • Release: github-release from .claude/skills/github-release/SKILL.md.
  • Ordinary implementation tasks targeting develop: develop-task-flow from .claude/skills/develop-task-flow/SKILL.md.
  • Urgent fix for a released defect: hotfix-flow from .claude/skills/hotfix-flow/SKILL.md.
  • README writing/updating: readme from .claude/skills/readme/SKILL.md.
  • jig project installation and GitHub profile setup: jig-setup from .claude/skills/jig-setup/SKILL.md.
  • jig installation updates: jig-update from .claude/skills/jig-update/SKILL.md.
  • jig installation diagnostics: jig-doctor from .claude/skills/jig-doctor/SKILL.md.
  • Repository branch and file cleanup: repo-hygiene from .claude/skills/repo-hygiene/SKILL.md.
  • Procedure conformance audit of the history: conformance-audit from .claude/skills/conformance-audit/SKILL.md.
  • Version grading rubric: version-rubric from .claude/skills/version-rubric/SKILL.md.
  • Project type scan and rubric recommendation: rubric-scan from .claude/skills/rubric-scan/SKILL.md.

Repository Model

  • main and develop are protected against force pushes and deletion; direct pushes are allowed.
  • Work branches start from origin/develop: feature/<slug>, fix/<slug>, chore/<slug>.
  • A finished task is squash-merged into develop locally and pushed. There are no pull requests.
  • A release promotes develop to main with a fast-forward push (git push origin develop:main), then creates the vX.Y.Z tag and GitHub release from the CLI.
  • Release notes are written by the agent from the commits in the release range; there is no release-drafter and there are no release labels.

Terminology

  • jig product means the behavior and payload delivered to users: installed skills, installer/update behavior, generated dist/, plugin hooks, and state created in installed repositories.
  • jig source repository means this repository where the jig product is developed. Repo-local instructions, validation, project plans, and contributor tooling belong to this scope unless they are deliberately added to the product payload.
  • jig-managed project means an external repository where jig is installed and used. Its clone-local hooks, .jig/ files, Git config, and GitHub settings are managed-project state.
  • Avoid “this project” or “the current project” when the distinction affects implementation. Say jig product, jig source repository, or jig-managed project explicitly.

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.
