gemini

gemini is a skill for Claude Code from martineserios/thebrana. It costs 47 tokens per session (1,869 once invoked), scanned A, original, MIT.

A delegation workflow that sends suitable tasks to a Gemini command-line worker and brings the result back into the project process. It is intended for stateless work such as research, drafts, boilerplate, and batch summaries.

In plain words
What is it for?
Use it for research sweeps, document first drafts, boilerplate, test scaffolding, translations, batch summarisation, and competitive or market analysis.
Why use it?
It can offload repetitive or research-heavy work while keeping project decisions, task updates, and repository changes under the main workflow.

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 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.

The opening of the file, as written. The whole thing — 199 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/brana:gemini — Gemini Worker Delegation

Delegate a task to agy (the Gemini CLI worker). Claude orchestrates; Gemini executes as a stateless worker. Every result flows back through Claude into the brana system.

Usage

/brana:gemini "task description"   # inline task
/brana:gemini t-XXXX               # pull task from backlog

--bg (fire-and-continue) is out of scope for v1. Full lifecycle requires Claude present when agy finishes. Use Layer A (Bash: agy -p "...") for fire-and-forget sweeps.

agy-Eligible Task Types

Type Notes
Research sweep Atomic, read-only, Gemini Flash speed
Boilerplate generation ⚠️ Convention-sensitive — ruflo required
Doc first draft ⚠️ Pass explicit "why" context in task description
Conversion/translation Deterministic, speed matters
Batch summarization Parallel, repetitive
Test scaffolding ⚠️ Convention-sensitive — ruflo required
Competitive/market analysis Research-heavy, brana-agnostic

Never Delegate (Claude-native)

system/ changes · git operations · tasks.json writes · architectural decisions · multi-step stateful refactors · memory/session writes.


ToolSearch("select:mcp__ruflo__memory_search,mcp__ruflo__memory_store")

ROUTE

Validate the 4-question routing heuristic:

  1. Atomic? — completable in one agy -p call, no mid-task state 2a. System-isolated? — no writes to system/, git, hooks, tasks.json during execution 2b. Context-enrichable? — ENRICH can supply enough background for useful output
  2. Speed/token benefit? — repetitive, fast, or token-heavy for Claude

If any answer is no, abort. Tell the user why and suggest the appropriate tool (Claude directly, /brana:build, /brana:research, etc.).

Hard-block for convention-sensitive task types when ruflo is unavailable:

Convention-sensitive types: boilerplate generation, test scaffolding, ADR draft.

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.
