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 | $0.03065 | $0.03065 |
| Opus 5.5 | $0.01226 | $0.01226 |
| Sonnet 5.5 | $0.00613 | $0.00613 |
| Haiku 4.5 | $0.00307 | $0.00307 |
Grade A, and why
punt-kit AGENTS.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 14d 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.

Agent Instructions
This is punt-kit — the standards, design patterns, and scaffolding repo for Punt Labs. When working in any Punt Labs project, consult these standards and patterns.
Beads
This project uses bd (beads) for issue tracking. Run bd onboard to get started.

Standards
Each standard lives in its own document under standards/.
| Standard | What it covers |
|---|---|
| Distribution | Install paths (marketplace, PyPI, .mcpb), dependency pinning, installation scope, init vs install, uninstall requirements |
| CLI | CLI + plugin duality, required subcommands (install, doctor, version, serve), --json flag, shell completion |
| Tool Enable/Disable | User-owned CLAUDE.md, the bare @-import line, the zoned .punt-labs/<tool>/ subtree (vendored zone tool-owned), the enabled marker, enable/disable verbs, audit checks, sentinel migration |
| Plugins | plugin.json, MCP server declaration, extension points, required hooks (SessionStart + PostToolUse), tool naming, gitignore checklist |
| Hooks | Claude Code state machine, three-layer dispatch, shell gates, Python handlers, decision-block and workflow-gate patterns, startup performance, audit checklist |
| Permissions | Allow/prompt/deny tiers, settings.json vs settings.local.json, required allow and deny rules, plugin-distributed permissions |
| Filesystem | ~/.punt-labs/<tool>/ home layout, reserved subdirectories, per-project activation marker, migration from legacy dot-directories |
| Repo-Local State Directory | <repo>/.punt-labs/<tool>/ tool roots plus the machine-local .punt-labs/local/ zone, committed except local-convention paths (local/, *.local, *.local.*), live state never tracked (the seal pattern, chunk-based), the canonical gitignore block, subtree zones (vendored/config/local/marker) |
| Integration | Peer-tool discovery tiers L0–L5, presence markers, graceful degradation, integration matrix, bundled integrations |
| Logging | Centralized dictConfig, log locations, atomic append, file permissions, content escaping |
| Naming | Repo names, PyPI names, CLI names, slash commands, versioning (semver) |
| GitHub | Branch protection, CI/CD workflows, review bots (Qodo, Bugbot), required status checks, repo settings |
| Workflow | Issue tracking, workflow tiers, branch discipline, commits, quality gates, code review, session close protocol, design decision logs, cross-project integration |
| PR and Review | Local-first review: the PR as merge gate, review agents, remote reviewers as second opinion |
| Git | Git mechanics: branch check before commit, no-rewrite of pushed branches, conflict resolution, post-merge cleanup ordering, worktree lifecycle, submodules, mission trailers, stop-and-ask |
| Release Process | The /punt:auto release playbook, deterministic phases 1–11, cross-repo propagation |
| Release Requirements | End-state artifacts a release must satisfy in the originating repo and siblings |
| README | Required README structure, install trust tiers, tone and positioning |
| Makefile | Required Makefile targets; make check as the quality-gate entry point |
| Shell | POSIX sh vs bash, strict mode, shellcheck, install-script rules |
| Agent Engineering | Operating defaults for AI coding agents: judgment, scope, verification |
| Architecture | The engine-and-clients model: one engine, thin library/CLI/MCP/REST client surfaces |
| OO | The object-oriented stance shared by Python, Swift, and Pharo |
| Python | uv, ruff, mypy, pyright, pytest, typer + rich, FastMCP, the OO ratchet, release workflow |
| Go | Idiomatic Go: modules, small interfaces, explicit errors, go vet + staticcheck |
| C | Idiomatic C: memory ownership, -Werror, sanitizers |
| Swift | Idiomatic + protocol-oriented Swift; swiftformat, swiftlint, XcodeGen, XCTest |
| Pharo | Pharo/Smalltalk, image-based development, in-image linting |
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 AGENTS.md is an instructions file published in the GitHub repository punt-labs/punt-kit (1 stars, last pushed yesterday), licensed MIT. It adds 3,065 tokens to every session, about $0.0123 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.
