Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00213 | $0.00213 |
| Opus 5 | $0.00106 | $0.00106 |
| Sonnet 5 | $0.00043 | $0.00043 |
| Haiku 4.5 | $0.00021 | $0.00021 |
Grade A, and why
blueprint 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 6d 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.
What it actually says
Claude Code
@AGENTS.md
Blueprint keeps shared repository policy in AGENTS.md and only Claude-specific setup here.
Install Blueprint with npx skills add owainlewis/blueprint. Use /architecture, /design, /architecture-review, /plan, /test, /review, and /improve for one kind of engineering work. Use /task-to-pr to deliver one or more code changes. Use /codex-issue-coordinator only in Codex to coordinate a large GitHub issue batch through separate worker threads and gated merges.
Everything you call in Blueprint is a skill. /task-to-pr accepts tasks, tickets, pull requests, or a milestone and creates one pull request for each task. /codex-issue-coordinator is Codex-specific because it requires Codex thread and managed-worktree tools. AGENTS.md contains the repository rules.
The /architecture-review and /review phases use a fresh generic subagent. Blueprint does not require a separate reviewer agent definition.
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.

blueprint CLAUDE.md is an instructions file published in the GitHub repository owainlewis/blueprint (378 stars, last pushed 7d ago), licensed MIT. It adds 213 tokens to every session, about $0.0011 per session on Opus 5. A static security scan graded it A with 0 findings.
