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 | $0.00000 | $0.00265 |
| Opus 5 | $0.00000 | $0.00133 |
| Sonnet 5 | $0.00000 | $0.00053 |
| Haiku 4.5 | $0.00000 | $0.00026 |
Grade A, and why
02-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 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
API Rules (Express.js)
Service Pattern
- Business logic lives in
/lib/services/ - Controllers handle HTTP concerns only
- Services handle data transformation and validation
3-Layer Architecture
- ApiClient (
/lib/api/client.ts): HTTP, auth, error handling - Service Layer (
/lib/services/): Business logic, type mapping - Query Hooks (
/lib/queries/): React Query integration
Database
- MikroORM for entities and queries
- Use Context7 MCP for MikroORM patterns
- Migrations in
/hasura/migrations/
Endpoints
- Version prefix:
/v1(handled by router) - RESTful naming conventions
- JSON:API response format
- Add endpoint to
API_ENDPOINTSin/lib/api/constants.ts
Error Handling
- Use ApiError class for HTTP errors
- Log with proper levels (error, warn, info)
- Never expose internal errors to clients
Query Keys
- Centralize in
/lib/queries/keys.ts - React Query config: 5min staleTime, 10min gcTime
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.

02-api is a cursor rule published in the GitHub repository WellApp-ai/Well (341 stars, last pushed 25d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 265 tokens. 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.
