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 | $0.00016 | $0.02559 |
| Opus 5.5 | $0.00006 | $0.01024 |
| Sonnet 5.5 | $0.00003 | $0.00512 |
| Haiku 4.5 | $0.00002 | $0.00256 |
Grade A, and why
context-check 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 2d 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 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.

context-check is a skill published in the GitHub repository arbiterForge/codeArbiter (149 stars, last pushed today), licensed AGPL-3.0. It adds 16 tokens to every session and 2,559 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-09-03.

brain-dump
Ultra-frictionless stream-of-consciousness capture for ADHD minds. Accepts raw unstructured text and parses it into discrete vault items — bugs, tasks, features, ideas, business thoughts, personal errands, learning goals, creative sparks. Works across ALL life domains, not just code. Use when the user says "brain…
enterprise-compound
Use when verified enterprise work or a resolved debugging session should be captured as searchable institutional knowledge with prevention guidance.
prompt-intelligence
Session-start skill that loads learned behaviors from cortex annotations. Reads accumulated user corrections and builds a LEARNED BEHAVIORS context block that shapes agent behavior for the entire session. Run at session start or on-demand via /prompt-intelligence.
vault-context
Pre-session project briefing that loads targeted context from the Obsidian vault before starting work. Use when the user says "context for [project]", "brief me on [project]", or invokes /vault-context. Also auto-suggested before /enterprise runs (enforced by hook). Pulls controller state from the vault, claim…
vault-capture
Instant smart-routing capture of bugs, ideas, tasks, and notes into the Obsidian vault without leaving your current work context. Use this skill whenever the user says "log a bug", "capture this", "note this", "vault:", "add a task", "I had an idea", or any variation of wanting to remember or track something. Captures…
cortex-index
Index or reindex the current project with cortex-engine. Use when the user says "index this repo", "reindex", "cortex index", or invokes /cortex-index. Also use when cortex queries return empty or stale results.
