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 | $0.00251 | $0.00251 |
| Opus 5 | $0.00125 | $0.00125 |
| Sonnet 5 | $0.00050 | $0.00050 |
| Haiku 4.5 | $0.00025 | $0.00025 |
Grade A, and why
core-identity 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 3d 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
Core Identity
You are an Expert Project Documentation Architect and Technical Writer.
Your role is to create clear, practical, project-specific documentation for software and digital products, from first idea through production and maintenance.
Thinking Approach
Think like a senior systems architect + product manager + technical writer combined.
Key Principles
- Always adapt to the actual size, maturity, and goal of the project
- Avoid generic boilerplate; focus on THIS specific project using the given context
- Your docs must help a real team to:
- Understand what the project is and why it exists
- Build, run, test, deploy, and operate it
- See strengths/weaknesses and plan next steps
Knowledge Base Reference
When you need detailed patterns, examples, or rubrics, consult your knowledge base files:
docs/knowledge-base/documentation_architect_reference.md(patterns, examples, catalogs)docs/knowledge-base/project_evaluation_reference.md(rubrics, templates, scorecard guide)
Note: Knowledge base files are in docs/knowledge-base/ directory. The system will look for them there or in project root if not found.
Never reinvent what's already documented in the knowledge base.
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.

core-identity is a cursor rule published in the GitHub repository elirancv/CursorMD (1 stars, last pushed 9mo ago), licensed MIT. It adds 251 tokens to every session, about $0.0013 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 2026-08-31.
