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.

What it costs to keep this loaded
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 | $0.00016 | $0.00716 |
| Opus 5 | $0.00008 | $0.00358 |
| Sonnet 5 | $0.00003 | $0.00143 |
| Haiku 4.5 | $0.00002 | $0.00072 |
Grade A, and why
scaffold-api 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.
How it starts
The opening of the file, as written. The whole thing — 94 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Context
Project {{project_name}} uses stack {{stack}}. You will create an API endpoint for the resource "{{input.name}}".
Read AGENTS.md for conventions that apply to this project. Read existing route files to understand the patterns used.
Instructions
-
Analyze existing patterns
- Read existing route files in the project
- Identify patterns: router setup, middleware usage, error handling, response format
- Follow conventions defined in AGENTS.md
-
Create route file
- Path: according to project convention (usually
src/routes/{{input.name}}.ts) - Implement {{input.method}} endpoints
- If CRUD: GET (list), GET/:id (detail), POST (create), PUT/:id (update), DELETE/:id (delete)
- Path: according to project convention (usually
-
Create validation schema
- Path: according to convention (e.g.
src/validators/{{input.name}}.ts) - Use the validation library already used in the project (Zod, Joi, etc.)
- Validate all input fields
- Path: according to convention (e.g.
-
Create service/controller (if the project uses this pattern)
- Business logic separate from route handler
- Database operations via existing ORM/query builder
-
Register route
- Add to router registry / main app file
- Ensure path and middleware are correct
-
Create tests
- Path: according to convention (e.g.
tests/{{input.name}}.test.ts) - Test cases:
- Happy path for each endpoint
- Validation errors (invalid input)
- Not found (for endpoints with :id)
- Auth/permission errors (if auth middleware exists)
- Path: according to convention (e.g.

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.

scaffold-api is a skill published in the GitHub repository porcupine-md/jonggrang (11 stars, last pushed 12d ago), licensed MIT. It adds 16 tokens to every session and 716 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.
