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 | $0.00077 | $0.00205 |
| Opus 5 | $0.00039 | $0.00102 |
| Sonnet 5 | $0.00015 | $0.00041 |
| Haiku 4.5 | $0.00008 | $0.00020 |
Grade A, and why
prompt-library 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
Prompt Library
Full text of every Crafting Kit prompt. Browse references/ and load the prompt file that matches the user's stage. Standard entry points: 00_claude_base_prompt.md, 150_global_risk_gate.md, 151_intent_stage_router.md, 153_assumption_ban_contract.md, 154_execution_control.md, 155_tool_permission_policy.md, 156_human_approval_protocol.md, 157_validation_and_reporting_gate.md, 158_secret_and_runtime_credentials.md. The PROMPT_INDEX.md reference lists every prompt with its stage and status.
What ships with it
60 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
- 6d ago First seen · 9 lines · 77 tokens per session scan A e643e9c4bb52
prompt-library is a skill published in the GitHub repository cembasaranoglu/crafting-system-claude (5 stars, last pushed 4mo ago), licensed MIT. It adds 77 tokens to every session and 205 once invoked, about $0.0004 per session on Opus 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 2026-09-03.
