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 | $0.02390 | $0.02390 |
| Opus 5 | $0.01195 | $0.01195 |
| Sonnet 5 | $0.00478 | $0.00478 |
| Haiku 4.5 | $0.00239 | $0.00239 |
Grade A, and why
api-validation-workflow 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 yesterday.
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.
How it starts
The opening of the file, as written. The whole thing — 376 lines — stays where its author put it; the contents beside it link to each section on GitHub.
API Validation Workflow Integration
This rule defines how API validation tools (get_openapi_spec and make_api_request) should be integrated into the development workflow to enable autonomous testing and continuous validation of implemented features.

1.2 Mandatory Integration Points
During Work Phase:
- After implementing each endpoint
- After modifying API data structures
- Before marking tasks as complete
During Validation Phase:
- Complete validation of implemented feature
- Testing success and error scenarios
- API contract validation
During Revise Phase:
- Re-testing after fixes
- Regression validation
2. Tool Usage Protocols
2.1 get_openapi_spec Protocol
When to use:
- At the beginning of each development session
- After generating or modifying controllers
- Before implementing client/frontend code
- To understand existing API contracts
Usage workflow:
// 1. Ensure development server is running
await dev({ port: 3000, watch: true });
// 2. Fetch OpenAPI specification
const spec = await get_openapi_spec();
// 3. Analyze available endpoints
// 4. Plan tests based on specification
// 5. Store insights about the API
Knowledge storage:
- Always store significant API changes as
api_mappingmemories - Document new endpoints and their responsibilities
- Relate endpoints to features and requirements
2.2 make_api_request Protocol
When to use:
- After implementing any endpoint
- To test success scenarios (happy path)
- To test error scenarios and edge cases
- To validate changes in existing endpoints
- During API problem debugging
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-validation-workflow is a cursor rule published in the GitHub repository felipebarcelospro/igniter-js (242 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 2,390 tokens to every session, about $0.0120 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 2026-09-01.
