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 | $0.01429 | $0.01429 |
| Opus 5 | $0.00714 | $0.00714 |
| Sonnet 5 | $0.00286 | $0.00286 |
| Haiku 4.5 | $0.00143 | $0.00143 |
Grade A, and why
agent-chorus GEMINI.md 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 5d 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 — 147 lines — stays where its author put it; the contents beside it link to each section on GitHub.
BEFORE starting any task, read these 3 files in order:
- .agent-context/current/00_START_HERE.md
- .agent-context/current/30_BEHAVIORAL_INVARIANTS.md
- .agent-context/current/20_CODE_MAP.md Do NOT open repo source files until steps 1-3 are complete. Then open only files .agent-context identifies as relevant to your task.
Context Pack
When asked to understand this repository:
- Read
.agent-context/current/00_START_HERE.mdfirst. - Follow the read order defined in that file.
- Use the structured files if present for task routing, grouped reporting, and stop conditions.
- Only open project files when the context pack identifies a specific target.
Gemini Instructions For This Repo
Naming convention: Use
chorus agent-context ...commands. Legacy npm wrappers (npm run agent-context:*) are still available in this repo.
If Context Pack Is Missing or Stale

Agent Chorus Integration
This project is wired for cross-agent coordination via chorus.
Provider snippet: .agent-chorus/providers/gemini.md.
When a user asks about another agent's activity ("What is Claude doing?", "Compare Codex and Gemini outputs"), run Chorus commands first and answer with evidence from session output rather than reasoning.

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.
