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 | $0.01005 | $0.01005 |
| Opus 5 | $0.00502 | $0.00502 |
| Sonnet 5 | $0.00201 | $0.00201 |
| Haiku 4.5 | $0.00101 | $0.00101 |
Grade A, and why
symbi-gemini-cli 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.
This is a copy
100% identical to symbi-gemini-cli GEMINI.md — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Symbiont Governance Context
This environment uses the Symbiont trust stack for AI agent governance.
Key Concepts
- ORGA Loop: Observe -> Reason -> Gate -> Act. The Gate phase operates outside LLM influence and cannot be bypassed. Phase transitions are enforced at compile time via Rust's type system.
- Cedar Policies: Authorization rules controlling what agents and tools can do. Files use
.cedarextension. Evaluation at <1ms. - SchemaPin: Cryptographic verification of MCP tool schemas (ECDSA P-256). Ensures tools haven't been tampered with. Uses Trust-On-First-Use (TOFU) key pinning.
- AgentPin: Domain-anchored cryptographic identity for AI agents (ES256 JWT, 12-step verification).
- DSL: Symbiont's domain-specific language for defining agents declaratively. Files use
.dslextension.

Dual-Mode Operation
The extension operates in two modes, detected automatically via environment variables:
Mode A -- Standalone (extension-first)
Developer installs the extension directly. Gemini CLI loads hooks/MCP/skills.
The extension spawns its own symbi mcp server. Policy enforcement is advisory
plus Gemini CLI's native policy engine.
Mode B -- ORGA-managed (runtime-first)
Symbiont's CliExecutor spawns Gemini CLI as a governed subprocess.
The extension detects SYMBIONT_MANAGED=true and defers to the outer
ORGA Gate for hard enforcement. The inner extension provides awareness.
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.
