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 | $0.00045 | $0.02673 |
| Opus 5 | $0.00023 | $0.01337 |
| Sonnet 5 | $0.00009 | $0.00535 |
| Haiku 4.5 | $0.00005 | $0.00267 |
Grade A, and why
acquire-skills 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 11d 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 — 291 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Acquire Skills
Find and install skills for the current task — across both tech and thinking/reasoning dimensions.
Usage
/brana:acquire-skills — scan current activity + project
/brana:acquire-skills <task-id> — scan a specific task's needs
/brana:acquire-skills <keyword> — direct search ("cloudflare", "decision matrix")
Never suggest these (brana workflow internals)
The following skills are system workflow tools, not capability skills. Never surface them as recommendations:
build, backlog, close, sitrep, onboard, align, reconcile, ship, docs,
retrospective, review, gemini, claudemd, plugin, scheduler, do, log,
export-pdf, verify-docs, client-retire, cargo-machete, bash-defensive-patterns,
rust-skills, gsheets, meta-templates, mcp-builder, memory, discover.
Thinking skills ARE valid to recommend: decide, brainstorm, challenge, swot-analysis,
decision-matrix, critical-thinking-logical-reasoning, pre-mortem, inversion,
first-principles, second-order-thinking, six-thinking-hats, systems-thinking,
jobs-to-be-done.
Process
Step 0: Detect mode
From $ARGUMENTS:
- No argument: run Steps 1a + 1b (activity detection + tech scan)
- Task ID (t-NNN): read task from
.claude/tasks.json, extract subject + tags + description → use as context for both Steps 1a and 1b - Keyword: skip Steps 1a + 1b entirely, use keyword directly in Step 3
Step 1a: Detect activity type
Read the current conversation context (recent turns) and any task/argument provided.
Classify the primary activity the user is doing right now:
| Activity | Signals | Relevant thinking skills |
|---|---|---|
| Deciding | "should I", "A or B", "which option", "choose between" | decide, decision-matrix, six-thinking-hats |
| Strategizing | "market", "competitive", "direction", "positioning", "business model" | swot-analysis, systems-thinking, second-order-thinking, scenario-planning |
| Analyzing problem | "why is", "root cause", "debug", "understand", "what caused" | critical-thinking-logical-reasoning, first-principles, systems-thinking |
| Challenging / stress-testing | "risk", "what could go wrong", "is this right", "review this plan" | challenge, pre-mortem, inversion, critical-thinking-logical-reasoning |
| Ideating / exploring | "idea", "what if", "explore", "brainstorm", "new approach" | brainstorm, first-principles, jobs-to-be-done, second-order-thinking |
| Planning | "how to approach", "phases", "roadmap", "before starting" | pre-mortem, second-order-thinking, systems-thinking |
| Researching | "learn about", "understand", "how does X work" | critical-thinking-logical-reasoning, systems-thinking, jobs-to-be-done |
| Building | implementation, coding, writing features | tech skills only (Step 1b) |
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.

acquire-skills is a skill published in the GitHub repository martineserios/thebrana (3 stars, last pushed yesterday), licensed MIT. It adds 45 tokens to every session and 2,673 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.

auto
Intent-classified router, the front door to OrchestKit and the DEFAULT entry point for any goal-shaped request. Classifies a plain-English goal and routes it to the right specialist skill. Routing is never overhead, so use it even when the target skill seems obvious; skip only when already executing inside another…
a0-manage-plugin
Find useful Plugin Index matches; inspect, scan, install, update and manage Agent Zero plugins.
marketplace-purchase-vetting
Use this when the user asks whether a local listing is a scam, "too good to be true," worth looking at, or a good deal. Also use this when he asks you to find options — search/discover candidates, then vet the best ones. The goal is not a generic buying guide; it is a practical risk read with clear next steps.
janitor-discover
Find new skills on GitHub or check a specific skill before installing. Use when the user wants to search for skills, evaluate a skill URL, check overlap and security risk before installing, or compare a local skill against alternatives. Trigger with '/janitor-discover'.
