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 5.1 | $0.00000 | $0.00702 |
| Opus 5.5 | $0.00000 | $0.00281 |
| Sonnet 5.5 | $0.00000 | $0.00140 |
| Haiku 4.5 | $0.00000 | $0.00070 |
Grade A, and why
agent-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.
How it starts
The opening of the file, as written. The whole thing — 64 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent Development
Agent construction
Agents are built as properties on coordinator classes (AnalyzerAgent, DocumenterAgent, AIRulesGeneratorAgent):
@property
def _structure_analyzer_agent(self) -> Agent:
model, model_settings = self._llm_model
return Agent(
name="Structure Analyzer",
model=model,
model_settings=model_settings,
system_prompt=self._render_prompt("agents.structure_analyzer.system_prompt"),
tools=[FileReadTool().get_tool(), ListFilesTool().get_tool()],
retries=config.ANALYZER_AGENT_RETRIES,
)
- Model setup is OpenAI-compatible only:
OpenAIChatModel(model_name, provider=OpenAIProvider(base_url=..., api_key=..., http_client=create_retrying_client())). There is no Gemini/custom provider path. ModelSettings: temperature 0.0,max_tokens,timeout,parallel_tool_calls— all fromsrc/config.pyenv constants.
Prompts
- Jinja2 templates in YAML under
src/agents/prompts/(keys likeagents.<name>.system_prompt/user_prompt), loaded byPromptManagerand rendered viaself._render_prompt(key)withrepo_pathetc. as variables. - New agent → new prompt section in the matching YAML file, never inline prompt strings in Python.
Orchestration
- Analyzer: build a dict of task callables (one per non-excluded analysis), run through
WorkerPool(max_workers=self._config.max_workers). - AI-rules generator: fixed pair of tasks via
asyncio.gather(*tasks, return_exceptions=True). - After the run,
validate_succession(files): raiseValueErroronly if NO output file exists; warn on partial success listing missing files. - Each agent writes its own output file (
.ai/docs/*.md, README.md, CLAUDE.md/AGENTS.md,.cursor/rules/*.mdc); create parent dirs and clean absolute paths first.
Tools
class FileReadTool:
def get_tool(self):
return Tool(self._run, name="Read-File", takes_ctx=False, max_retries=...)
def _run(self, file_path: str, line_number: int = 0, line_count: int = 200) -> str:
"""Docstring is the LLM-facing description — keep Args/Returns accurate."""
...
raise ModelRetry(message="File not found") # recoverable errors → ModelRetry
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.

agent-development is a cursor rule published in the GitHub repository divar-ir/ai-doc-gen (768 stars, last pushed 2mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 702 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.
