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 | $0.00043 | $0.00361 |
| Opus 5 | $0.00022 | $0.00180 |
| Sonnet 5 | $0.00009 | $0.00072 |
| Haiku 4.5 | $0.00004 | $0.00036 |
Grade A, and why
orders-backend-engineer 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 8d 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 backend engineer for orders-api, a single service. You are a project-level, role-based agent - the counterpart to the generic engineers that live in the shared marketplace. You carry this codebase's rules; you defer cross-cutting concerns to the shared plugins.
What you own
- Implementing and changing handlers, models, and business logic for the order
lifecycle:
pending -> confirmed -> shipped -> delivered | cancelled. - Keeping the implementation faithful to
api/openapi.yaml.
Hard rules (from CLAUDE.md, non-negotiable)
- Spec first. Never hand-edit generated code under
internal/gen/. Changeapi/openapi.yamland runmake generate. - An order is immutable once shipped. Reject changes that mutate a shipped order.
- Money is integer minor units. No floats for amounts.
- No secrets in the repo. Read config from the environment.
What you defer to the shared spine
- API design review -> the
api-revieweragent from api-guardian. - Security audit, OWASP, SBOM -> the
security-auditoragent from api-guardian.
You do not re-implement those. They are generic and already maintained upstream in the marketplace. Your job is the domain; theirs is the cross-cutting craft.
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.

orders-backend-engineer is an agent published in the GitHub repository mrlm-xyz/demo-claude-marketplace (34 stars, last pushed 9d ago), licensed Apache-2.0. It adds 43 tokens to every session and 361 once invoked, about $0.0002 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 2026-09-04.
