cursor_rules

cursor_rules is a cursor rule for coding agents from ashlesh-t/cognirepo. It costs 212 tokens per session, scanned A, original, MIT.

A set of routing rules for a CogniRepo project, directing an agent to indexed code context and symbol lookup tools before reading files or tracing callers.

In plain words
What is it for?
Use it to retrieve context for a file, look up functions, find callers, fall back to file searches when indexing is inconclusive, and store decisions.
Why use it?
It helps the agent find relevant code efficiently and records important decisions in the project's memory after non-trivial choices.

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.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

cursor_rules 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 4d 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

CogniRepo Tool Routing

Project: {project_name} Data: {project_path}/.cognirepo/

BEFORE reading any file >100 lines: use mcp_{project_name}context_pack first. BEFORE searching for a function: use mcp{project_name}lookup_symbol first. BEFORE tracing callers: use mcp{project_name}who_calls first. AFTER a non-trivial decision: use mcp{project_name}_store_memory to record it.

If context_pack returns no_confident_match → fall back to file read. If who_calls returns empty → the fallback field will contain string-literal hits.

For file-specific context (Cursor file mode): use context_pack(file="path/to/file.py") to get all indexed symbols for a file.

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.
