Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.00714 |
| Opus 5.5 | $0.00000 | $0.00286 |
| Sonnet 5.5 | $0.00000 | $0.00143 |
| Haiku 4.5 | $0.00000 | $0.00071 |
Grade A, and why
04-cli-development 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 1mo 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
CLI development & Rule generation
When you modify the CLI or add new stack templates:
-
CLI
- Update prompts in
cli/index.js. - Organize services in appropriate files in
cli/services/:base-service.js- Base functionality shared across all servicesfile-service.js- File operations and template processingconfig-service.js- Configuration and constants managementstack-service.js- Common stack functionalitymcp/mcp-service.js- MCP tools integration (v2.0+)- Stack-specific services in
stack/directory (e.g.,stack/nextjs-service.js,stack/laravel-service.js)
- Respect
templates/kit-config.jsonfor configuration. - Add/adjust helper scripts in
version-detector.js.
- Update prompts in
-
New stacks or architectures
- Create
templates/stacks/<stack>/base/with generic rules. - Create
templates/stacks/<stack>/architectures/<arch_name>/with architecture-specific rules. - Add overlay folders
v<major>/for breaking changes only. - Update
kit-config.json:globsversion_rangesdefault_architecturearchitecturesfor stack-specific architecturespattern_rulesif needed.
- Create
-
MCP Tools (v2.0+)
- Create
templates/mcp-tools/<tool>/with tool-specific rules. - Add tool usage patterns and best practices.
- Update
kit-config.jsoninmcp_toolssection:name- Display name for the tooldescription- Detailed description of functionality
- Test multi-select functionality in CLI.
- Create
-
Template variables
- Use placeholders like
{projectPath},{detectedVersion},{versionRange},{stack}in templates. - These will be automatically replaced when generating rules.
- Use placeholders like
-
Docs
- Document new behaviour in
README.md&/docs/cli.md. - Update
/docs/mcp-tools-guide.mdfor MCP tools changes. - Change
Implementation Statusblock with percent progress of current implementations and add new if is a new implementation.
- Document new behaviour in
-
CLI Testing
-
Always use
--autoor--auto-installwhen testing CLI commands to avoid interactive prompts -
Test different IDEs with specific flags:
# Test with auto-install (no prompts) node cli/index.js --stack=laravel --version=12 --global --auto # Test different IDEs node cli/index.js --stack=react --version=18 --ide=claude --auto node cli/index.js --stack=nextjs --version=14 --ide=vscode --auto -
Verify file generation in correct directories:
- Cursor:
.cursor/rules/rules-kit/ - Claude:
CLAUDE.md - VS Code:
.github/copilot-instructions.md
- Cursor:
-
Test backup functionality for existing files
-
After changes, run:
pnpm run lint
pnpm run test
pnpx agent-rules-kit --update
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.

04-cli-development is a cursor rule published in the GitHub repository tecnomanu/agent-rules-kit (36 stars, last pushed 1y ago), licensed ISC. It costs nothing until one of its globs matches a file; then it loads 714 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.
