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 | $0.00028 | $0.00392 |
| Opus 5 | $0.00014 | $0.00196 |
| Sonnet 5 | $0.00006 | $0.00078 |
| Haiku 4.5 | $0.00003 | $0.00039 |
Grade A, and why
help 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
Cortex Help
Cortex remembers your decisions, conventions, and lessons across sessions. Here's how to use it:
Quick Start - Try These Now
-
Store a coding convention:
Remember: "Always use path.join() for file paths, never hardcoded / or \\" -
Recall a past bugfix:
What did I learn about race conditions in async UI code? -
Check your brain status:
/cortex:status
How to Store Knowledge
Just tell Cortex what you want it to remember:
- Conventions: "Remember: we use conventional commits (feat:, fix:, docs:)"
- Decisions: "Store: chose SQLite over Postgres for local-first storage"
- Bugfixes: "Lesson learned: NTFS file locking requires LockFileEx on Windows"
- Architecture: "Decision: API uses REST + JSON, not gRPC"
Cortex will automatically store it with context.
How to Recall Knowledge
Ask naturally:
- "What conventions do we have for error handling?"
- "Why did we choose Tokio over async-std?"
- "Remind me about the Windows path issue"
Commands
/cortex:status- Show brain status (memories, daemon, mode)/cortex:recall <query>- Search your memories/cortex:store <decision>- Store a decision with context
Modes
- Solo mode (default): Your brain is local at
~/.cortex/ - Team mode: Connect to a shared server with
CORTEX_URLconfig
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.

help is a skill published in the GitHub repository AdityaVG13/cortex (9 stars, last pushed 2d ago), licensed MIT. It adds 28 tokens to every session and 392 once invoked, about $0.0001 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.
