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 | $0.01369 | $0.01369 |
| Opus 5.5 | $0.00548 | $0.00548 |
| Sonnet 5.5 | $0.00274 | $0.00274 |
| Haiku 4.5 | $0.00137 | $0.00137 |
Grade A, and why
shapeup-sdlc-plugin 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 27d 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 — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
@AGENTS.md
Above the rule: the shipped harness doc. Below: guidance for developing this repo.
What this repo is
A Claude Code plugin (shapeup-sdlc). AGENTS.md is a shipped product artifact —
bin/init.mjs splices its <!-- HARNESS_START -->…<!-- HARNESS_END --> block into
consumer projects. Editing it is a product change: speak in skills/commands/options,
never .mjs paths.
Commands
npm test— Tier-0 structural suite (tests/structural/); zero deps, no install step.claude plugin validate . --strict(and the same for./.claude-plugin/marketplace.json) — CI parity.claude --plugin-dir .— load the working copy without installing.npm run demo— regeneratesdocs/assets/demo-gate.svgby running the real gate hook; never hand-edit the SVG.npm run verify:cross-dir— the cheap release-candidate check below, as a script instead of a manual exercise: fireshooks/sandbox-guard.mjsfrom agit archivecopy at a different path, against a scratch consumer project, and confirms the decision lands. Run before a release that toucheshooks/orkernel/lib/paths.mjs.
Rules that prevent breakage
- Zero dependencies is load-bearing: executable code is plain Node ESM (
.mjs),node:builtins only, no network calls anywhere. - Hooks fail open, never closed, unless the bad state is positively proven
(
hooks/sandbox-guard.mjsis the reference implementation). - A version bump touches both
package.jsonand.claude-plugin/plugin.json; release CI fails on mismatch. - A new worker skill takes 3 steps:
SKILL.md→ declare fields inkernel/schemas/domain.schema.json→ teachharness compileandharness reduce ingest. Step 1 alone yields a skill the orchestrator can't dispatch. tools/is repo-only and never ships; what ships is thefilesallowlist inpackage.json.- Commit subjects:
type(scope): lowercase declarative. - A gate code, or a new custom notation symbol in the spirit of
✦ ✚ ★ ✧ ⚙ ⏸ ~(not an ordinary character like✅), introduced inAGENTS.mdneeds a matching row in its Gate Vocabulary & Symbol Legend section, in the same commit —harness-maintenance-auditchecks this both ways (an unglossed code/symbol, and a legend row nothing uses).
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.
