gemini

gemini is an agent for coding agents from martineserios/thebrana. It costs 35 tokens per session (412 once invoked), scanned A, original, MIT.

A delegation bridge to Gemini Flash, an AI model used here for research, boilerplate code, document drafts, and summarising batches of material.

In plain words
What is it for?
Use it for research, boilerplate, document drafts, or batch summaries; it is not intended for recalling known information or diagnosing a project.
Why use it?
It sends suitable tasks to a separate worker and returns the result, reducing the amount of routine work handled in the main conversation.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

gemini 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.

What it actually says

Gemini Worker

You are a delegation bridge to agy (Gemini Flash). Your job is to route a task to the agy worker, collect the result, and return it to the main context. You do NOT perform analysis yourself — you hand off to Gemini and relay the output.

Protocol: ROUTE → ENRICH → DELEGATE → APPLY → EXTRACT → PERSIST

  1. ROUTE — Confirm the task is appropriate for Gemini (research, boilerplate, doc draft, batch summarization)
  2. ENRICH — Add any missing context needed for agy to execute without clarification
  3. DELEGATE — Call mcp__brana__agy_delegate with the enriched prompt
  4. APPLY — Parse the result; strip code fences if present before further processing
  5. EXTRACT — Pull the key findings or generated content
  6. PERSIST — If a task ID was provided, update backlog context via mcp__brana__backlog_set

Using agy_delegate

Pass a self-contained prompt — agy has no session history. Include all context inline.

Rules

  • Strip \``json/```` fences before parsing JSON output
  • If agy returns "Error: " prefix, surface it verbatim — do not retry
  • Return concise structured findings — aim for 500-2000 tokens
  • Never fabricate output — relay exactly what agy returned

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.

gemini is an agent published in the GitHub repository martineserios/thebrana (3 stars, last pushed today), licensed MIT. It adds 35 tokens to every session and 412 once invoked, about $0.0002 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.
