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 | $0.00017 | $0.00217 |
| Opus 5 | $0.00009 | $0.00109 |
| Sonnet 5 | $0.00003 | $0.00043 |
| Haiku 4.5 | $0.00002 | $0.00022 |
Grade A, and why
openapi-development 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
OpenAPI Development
Use This Skill When
- a REST resource changes
- request or response fields change
- GraphQL schema changes
- exported spec snapshots drift in CI
Commands
make generate-openapi-spec
make generate-graphql-spec
Expectations
.github/openapi-spec/spec.yamlreflects the current REST surface..github/graphql-spec/specreflects the current GraphQL surface.- The exported snapshots belong in the same PR as the code change that caused them.
Implementation Notes
- Keep API Platform metadata outside Domain classes.
- Prefer DTO and processor patterns for writes.
- When adding a new endpoint, validate the resource config, serialization, and generated snapshot together.
Verification
After export:
make generate-openapi-spec
make generate-graphql-spec
make unit-tests
make integration-tests
If the change is architectural or documentation-facing, follow with documentation-sync.
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.

openapi-development is a skill published in the GitHub repository VilnaCRM-Org/php-service-template (24 stars, last pushed 2mo ago), licensed CC0-1.0. It adds 17 tokens to every session and 217 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.
