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 | $0.00699 | $0.00699 |
| Opus 5.5 | $0.00280 | $0.00280 |
| Sonnet 5.5 | $0.00140 | $0.00140 |
| Haiku 4.5 | $0.00070 | $0.00070 |
Grade A, and why
market 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.
This is a copy
95% identical to market AGENTS.md — 2 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.
How it starts
The opening of the file, as written. The whole thing — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This repository is a public marketplace. Every contribution must be reusable, customer-neutral, and safe to index publicly.
Public information boundary
- Never put a tenant, customer, prospect, partner, or other confidential identity in tracked files, paths, filenames, Agent, Team or Skill IDs, frontmatter, descriptions, examples, fixtures, memories, generated artifacts, or screenshots.
- Apply the same rule to Git metadata and collaboration text: branch names, commit subjects and bodies, PR or issue titles and bodies, comments, and review replies.
- Describe reusable capabilities with domain-neutral roles and entities. Put customer-specific prompts, facts, mappings, examples, data, and deployment settings only in private AgentFS homes, private repositories, or private runtime configuration.
- Do not add a real confidential token to a denylist, test fixture, documentation, or example. A literal denylist in a public repository creates a second leak.
External dependency disclosure
- A Skill, Agent or Team that relies on separately licensed, purchased, hosted, or
deployed third-party software must disclose that dependency in its discovery
description,
compatibilityfield, localized marketplace text, and execution instructions. - Distinguish an included connector or adapter Tool from the external product it accesses. Never imply that registering a Tool bundles, licenses, installs, pays for, or operates the third-party product.
- State the operator prerequisites, applicable licensing or usage terms, separate costs when relevant, connection readiness checks, and safe degraded behavior. If the dependency is unavailable, stop before the external call and never fabricate a successful result.
Required pre-publication check
Before committing or opening/updating a PR:
- Obtain the sensitive tokens through a private channel and keep them outside the repository.
- Scan the complete working tree, including hidden files while excluding
.git. - Scan new path names, branch names, commit subjects and bodies, and the proposed PR/issue/review text.
- Review examples semantically: changing a proper noun is insufficient when an example still exposes a customer-specific organization shape or private fact.
- Run the repository validation and translation-freshness checks documented in
README.md.
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.
