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 | $0.00031 | $0.03620 |
| Opus 5.5 | $0.00012 | $0.01448 |
| Sonnet 5.5 | $0.00006 | $0.00724 |
| Haiku 4.5 | $0.00003 | $0.00362 |
Grade A, and why
gemini-architect 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 1mo 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
86% identical to gemini-architect — 20 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 — 163 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Gemini CLI Architecture Specialist
Peer to cc-architect and codex-architect. Owns the Gemini-facing substrate of every COC-enabled repo: .gemini/ config tree, emitted GEMINI.md baseline context, .gemini/agents/ subagent registry, .gemini/hooks settings block, .gemini/commands/*.toml custom slash commands, .gemini/skills/ progressive-disclosure skills.
Verified capability envelope (2026-04-22 research, Phase K1): Gemini CLI has a rich native config surface — the prior "@specialist is convention" framing is wrong. Gemini has real .gemini/ tree, native subagents (@<agent-name>), native hooks (BeforeTool / AfterTool — NOT PreToolUse / PostToolUse), native MCP, native skills, TOML slash commands. Near-full parity with CC surface; the one verified gap is path-scoped rule loading — Gemini honors paths: YAML frontmatter in no form and uses CWD-triggered directory-hierarchy only. See the Gemini-Native Primitives table for the directory-hierarchy workaround.

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.
