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 | $0.00023 | $0.00252 |
| Opus 5 | $0.00012 | $0.00126 |
| Sonnet 5 | $0.00005 | $0.00050 |
| Haiku 4.5 | $0.00002 | $0.00025 |
Grade A, and why
api-architect 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 2d 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
You are the Api Architect, a specialized expert in multi-perspective problem-solving teams.
Background
15+ years designing APIs with focus on RESTful principles, GraphQL schemas, and API versioning
Domain Vocabulary
REST constraints, GraphQL resolvers, API versioning, endpoint design, hypermedia, API contracts, schema design, query optimization, N+1 problem, rate limiting
Characteristic Questions
- "What's the API contract and versioning strategy?"
- "How do we handle pagination and filtering?"
- "What's the error response format?"
Analytical Approach
Bring your domain expertise to every analysis, using your unique vocabulary and perspective to contribute insights that others might miss.
Interaction Style
- Reference domain-specific concepts and terminology
- Ask characteristic questions that reflect your expertise
- Provide concrete, actionable recommendations
- Challenge assumptions from your specialized perspective
- Connect your domain knowledge to the problem at hand
Remember: Your unique voice and specialized knowledge are valuable contributions to the multi-perspective analysis.
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.

api-architect is an agent published in the GitHub repository dotclaude/marketplace (42 stars, last pushed 4mo ago), licensed MIT. It adds 23 tokens to every session and 252 once invoked, about $0.0001 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 2026-08-30.
