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 | $0.00667 | $0.00667 |
| Opus 5.5 | $0.00267 | $0.00267 |
| Sonnet 5.5 | $0.00133 | $0.00133 |
| Haiku 4.5 | $0.00067 | $0.00067 |
Grade A, and why
grace-marketplace 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.
How it starts
The opening of the file, as written. The whole thing — 56 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Repository Context
This repository is the GRACE marketplace package, not an end-user application.
GRACE means Graph-RAG Anchored Code Engineering: a contract-first AI engineering methodology built around semantic markup, XML planning artifacts, knowledge-graph navigation, and verification/log-driven execution.
What This Repo Contains
skills/grace/*contains the canonical skill sources.plugins/grace/skills/grace/*contains the packaged mirror used for Claude marketplace/plugin distribution..claude-plugin/marketplace.jsondefines the marketplace entry.plugins/grace/.claude-plugin/plugin.jsondefines the packaged plugin manifest.openpackage.ymldefines OpenPackage metadata.README.mdis the user-facing overview and install guide.package.json,src/grace.ts, andsrc/grace-lint.tsdefine the published Bun-powered CLI package@osovv/grace-cliand thegrace lintcommand.scripts/validate-marketplace.tsvalidates packaging, path safety, version sync, and packaged-vs-canonical drift.
Core Purpose
The repository packages and distributes GRACE skills so coding agents can:
- initialize GRACE project artifacts
- plan module architecture and contracts
- design verification and log evidence
- execute plans sequentially or in parallel-safe waves
- inspect project health, refresh drift, review integrity, explain GRACE, and answer project questions
This repo is mainly about methodology content, skill instructions, and marketplace packaging.
Important Working Rules
- Treat
skills/grace/*as the main source of truth unless a task is explicitly about packaged output. - Keep
plugins/grace/skills/grace/*synchronized with the canonicalskills/grace/*copies when published skills change. - Keep versions synchronized across
README.md,openpackage.yml,.claude-plugin/marketplace.json, andplugins/grace/.claude-plugin/plugin.json. - Validate repo integrity with
bun run ./scripts/validate-marketplace.tsafter packaging or metadata changes. - For CLI changes, run
bun run validate:cliand exercisegrace lintagainst a complete temporary or fixture GRACE 4 project. This packaging repository does not yet contain its own.gracestate, sobun run grace lint --path .is expected to reportproject.missing-graceuntil a separate self-migration is approved. - Do not assume every directory under
skills/grace/is published; the actual shipped set is declared in.claude-plugin/marketplace.json.
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.
