What is punt-kit CLAUDE.md?

Project instructions for punt-kit and Claude Code, covering scratch files, quality checks, issue tracking, and the lifecycle of its Python package and plugin.

Use them while developing punt-kit to run the required checks, manage beads, store temporary files, and handle plugin configuration safely.

They explain the rules an agent must follow before commits and when changing project or plugin files.

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.

Model	Per session	Once invoked
Fable 5.1	$0.04798	$0.04798
Opus 5.5	$0.01919	$0.01919
Sonnet 5.5	$0.00960	$0.00960
Haiku 4.5	$0.00480	$0.00480

Security

Grade B, and why

punt-kit CLAUDE.md scanned grade B with 1 finding 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 4d 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.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Agent Instructions

This project follows Punt Labs standards.

Scratch Files

Use .tmp/ at the project root for scratch and temporary files — never /tmp. The TMPDIR environment variable is set via .envrc so that tempfile and subprocesses automatically use it. Contents are gitignored; only .gitkeep is tracked.

Quality Gates

Run before every commit. Zero violations, zero errors, all tests green.

make check

The Makefile is the source of truth for what check means (make help lists targets).

Beads: Dual Role

punt-kit .beads/ tracks both project-specific work (punt-kit tooling, standards doc updates) and org-wide cross-project work (CI rollouts, security enablement, multi-repo changes). See the parent CLAUDE.md for the full placement scheme.

Plugin Lifecycle

punt-kit is both a Python package (punt CLI) and a Claude Code plugin (punt@punt-labs on the marketplace). The plugin wraps the CLI with slash commands (/punt init, /punt audit, /punt reconcile, etc.).

Key rules

Never hand-edit plugin JSON config files (installed_plugins.json, enabledPlugins, cache dirs). Use claude plugin CLI commands or the /plugin slash command instead.
Plugin changes require a publish cycle: bump version in plugin.json → push → update marketplace catalog (punt-labs/claude-plugins) → user runs /plugin update.
Dev/prod isolation: the working tree uses name: "punt-dev" so developers see both punt:* (marketplace) and punt-dev:* (local) commands side by side. Launch with claude --plugin-dir plugin from the repo root.
Can't run claude inside a session — ask the user to run plugin CLI commands in a separate terminal when needed.

Repository layout

The plugin surface — everything a marketplace install is meant to use — lives under plugin/ (DES-025, DES-028):

Path	Contents
`plugin/.claude-plugin/plugin.json`	Manifest. No `mcpServers` — punt is a prompt-and-command surface over the `punt` binary from PyPI.
`plugin/commands/`	Slash commands (`name.md` + `name-dev.md` pairs).
`plugin/skills/`	The `auto` playbook-executor skill.
`plugin/playbooks/`	Playbook YAMLs the `auto` skill loads from `${CLAUDE_PLUGIN_ROOT}/playbooks/`.

Changes

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.

punt-kit CLAUDE.md is an instructions file published in the GitHub repository punt-labs/punt-kit (1 stars, last pushed yesterday), licensed MIT. It adds 4,798 tokens to every session, about $0.0192 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
