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 | $0.00053 | $0.01365 |
| Opus 5.5 | $0.00021 | $0.00546 |
| Sonnet 5.5 | $0.00011 | $0.00273 |
| Haiku 4.5 | $0.00005 | $0.00136 |
Grade A, and why
brain-plan 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.
How it starts
The opening of the file, as written. The whole thing — 116 lines — stays where its author put it; the contents beside it link to each section on GitHub.
brain-plan: Project Planning
Help the user decompose a goal into concrete, actionable tasks with priorities, deadlines, and logical ordering. This is collaborative planning — the agent facilitates, the user decides.
Trigger Phrases
- "Let's plan [project]", "Help me plan..."
- "Break this down", "How should I approach this?"
- "I need to figure out how to..."
- "New project: ...", "I want to start..."
- "What are the steps for...?"
Workflow
Step 1 — Identify the Scope
Determine if this is:
- A new project that needs to be created
- An existing project that needs task breakdown
- A vague goal that needs clarification first
If new: ask for a one-sentence description of what "done" looks like.
If existing: call get_project_context to see current state.
If vague: help clarify with one question — "What would it look like if this was finished?"
Step 2 — Brainstorm Tasks
Ask:
"What are the main things that need to happen to get this done?"
Let the user brain-dump. Then help structure their response:
- Break large items into smaller tasks — if something takes more than a day of effort, it probably should be 2-3 tasks
- Make tasks actionable — each should start with a verb: "Write", "Build", "Research", "Contact", "Deploy"
- Identify dependencies — "What needs to happen first?"
- Spot missing steps — "I notice you mentioned X but not Y — do we need that?"
Present the proposed task list and ask for confirmation before creating anything.
Step 3 — Add Metadata
For the confirmed tasks:
- Sequence — order tasks logically (dependencies first)
- Priority — ask about the first 2-3 most important tasks: "Which of these is the most critical to get right?"
- Deadlines — if the project has an overall deadline, work backwards: "If this needs to be done by [date], when should each piece be finished?"
- First task — identify the single next action: "If you were starting right now, what would you do first?"
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.

brain-plan is a skill published in the GitHub repository SanderMoon/local-brain (9 stars, last pushed 7mo ago), licensed MIT. It adds 53 tokens to every session and 1,365 once invoked, about $0.0002 per session on Opus 5.5. 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.
Other skills, from other repositories
starting-a-new-project
Use when the workspace is empty, has no code, and the user brings a raw project idea. Normally reached via setting-up-a-project; not for an existing project.
pm
Use when the user wants product requirements rather than code: 'write a PRD', 'product requirements', 'spec this feature for the team', 'ooo pm'. Runs a PM-focused interview with automatic question classification and produces a PRD/PM document. Not for implementation requests.
publish
Publish Seed specification as GitHub Issues for team-based project management.
client-onboarding
Use when a deal closed or a user signed up and the first 30 days need an activation plan: sales→delivery handoff, one verifiable activation event, kickoff, and a 30/60/90 or day-0→14 plan with owners, dates and a measurable exit. NOT reactive ticket triage (that is customer-support), NOT renewals/churn past the…
procurement
Use when a small operator must choose what to buy and from whom: pick a supplier, write an RFI/RFQ/RFP that returns comparable bids, score quotes on total cost of ownership, negotiate price and payment terms, or judge single-source risk. NOT redlining the purchase agreement (that is contracts), NOT the price you…
proposals
Use when writing the document a buyer reads to say yes — a commercial proposal or Statement of Work, turning discovery notes into a scoped and priced document, adding tiers so the middle one wins, or diagnosing a proposal that will not close. NOT the binding legal agreement with its liability and IP clauses (that is…
