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 | $0.00497 |
| Opus 5 | $0.00000 | $0.00249 |
| Sonnet 5 | $0.00000 | $0.00099 |
| Haiku 4.5 | $0.00000 | $0.00050 |
Grade A, and why
backend-express 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.
What it actually says
Backend Conventions
Architecture (routes → controllers → models)
server/src/routes/feature.js — Route definitions, middleware attachment
server/src/controllers/featureController.js — Business logic, request/response
server/src/models/Feature.js — Mongoose schema & model
server/src/middleware/ — auth.js (JWT), roleGuard.js (role check)
server/src/utils/ — email.js, upload.js
Patterns
- ES modules — use
import/export, every file uses.jsextension in imports - Route files use
Router()from Express, exported as default - Controllers are named exports:
export const getItems = async (req, res) => {} - Always wrap controller logic in try/catch, return
res.status(code).json({ message }) - Use
req.user(set by auth middleware) for the authenticated user - Role checks:
roleGuard("president", "pm")— pass allowed roles as arguments
Mongoose Models
- Schema defined with
new mongoose.Schema({...}, { timestamps: true }) - Passwords hashed in
pre("save")hook with bcryptjs - Refs use
mongoose.Schema.Types.ObjectIdwithref: "ModelName" - Subdocuments for embedded arrays (e.g., attendees in Event, timeline in Decision)
API Route Prefix
All routes mounted under /api/:
/api/auth— login, register, me/api/events— CRUD + checkin/api/members— list, count, status change/api/decisions— CRUD with filters/api/strikes— list, member strikes, summary, assign/api/candidates— list, submit (multipart), approve, reject
Auth Flow
- Client sends
POST /api/auth/loginwith email + password - Server returns
{ token, user }— JWT valid for 7 days - Client stores token in localStorage, attaches via axios interceptor
- All protected routes use
authmiddleware → setsreq.user - Role-restricted routes add
roleGuard(...)afterauth
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.

backend-express is a cursor rule published in the GitHub repository ayimmam/PCIC (2 stars, last pushed 1mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 497 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 2026-08-31.
