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 | $0.00427 | $0.00427 |
| Opus 5 | $0.00214 | $0.00214 |
| Sonnet 5 | $0.00085 | $0.00085 |
| Haiku 4.5 | $0.00043 | $0.00043 |
Grade A, and why
development-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.
What it actually says
Development Workflow and Standards
Code Quality
Linting
- ESLint configuration in eslint.config.mjs
- Run linting:
npm run lint - TypeScript checking included in lint process
Testing
- Mocha + Chai testing framework
- Test files in
tests/directory with.tests.jssuffix - Run tests:
npm test - Coverage reports:
npm run test-cov
Development Scripts
Available in package.json:
npm run dev- Development server with nodemonnpm run lint- ESLint + TypeScript checkingnpm test- Run test suitenpm run test-cov- Tests with coveragenpm run ci- Full CI pipeline (lint + test-cov)npm run clear- Clean build artifacts
File Organization
Source Code (src/)
- Keep related functionality grouped in subdirectories
- Use clear, descriptive file names
- Follow existing patterns for consistency
Templates (assets/tmpl/)
- Template files use
.tmplextension - Maintain template structure for project scaffolding
- Update templates when adding new features
Examples
- Comprehensive examples in tests/bootstrap.js
- Simple examples in
examples/directory - Keep examples up-to-date with API changes
Dependencies
Runtime Dependencies
- Koa.js ecosystem (koa, koa-bodyparser, koa-session, etc.)
- Validation with validatorjs
- WebSocket support with ws
- UUID generation
- CLI tools from @axiosleo/cli-tool
Development Dependencies
- TypeScript for type checking
- ESLint for code quality
- Mocha/Chai for testing
- NYC for coverage reporting
Version Requirements
- Node.js >= 16.0.0
- Use modern JavaScript features (async/await, destructuring, etc.)
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.

development-workflow is a cursor rule published in the GitHub repository AxiosLeo/node-koapp (129 stars, last pushed 18d ago), licensed MIT. It adds 427 tokens to every session, about $0.0021 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.
