brief

brief is a skill for Claude Code from mshadmanrahman/pm-pilot. It costs 90 tokens per session (1,614 once invoked), scanned A, original, MIT.

A command that turns a decision question into a sourced decision brief. It reads evidence from a local folder, records supporting and opposing information, names missing evidence, and ends with a decision state.

In plain words
What is it for?
Use it for questions such as whether to prioritize a feature, when you need a reviewable recommendation based on documents in a folder.
Why use it?
It reduces the risk of making a decision from unsupported claims, unchecked quotations, or one-sided evidence.

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

brief 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 — 152 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Brief

One command, one decision, one reviewable artifact.

/pm-core:brief "Should we prioritize bulk import for mid-market?"

This is the first thing a new user should run. It needs no MCP servers, no configuration, and no knowledge of the other skills. It reads a folder of evidence, produces a decision brief, and forces a decision state at the end.

When to Activate

  • User runs /pm-core:brief with or without a question
  • User asks "should we X", "help me decide on X", "make the case for X"
  • User asks what the evidence says about a decision they are facing
  • A new user has just installed PM Pilot and does not know where to start

The contract

A brief is not a summary. It is an argument with its sources attached, and it is only useful if a reader can check it. So:

  • Every consequential claim names where it came from.
  • Every direct quote is verified against its source before delivery.
  • Evidence that cuts against the recommendation is stated, not omitted.
  • Evidence that does not exist is named as missing, not inferred.
  • The brief ends in a decision state, not in a draft.

If you cannot meet all five, say which one failed and why. Never deliver a brief that looks complete when it is not.

Execution

Step 1: Name the decision

Take the decision from the user's argument. If they ran the command bare, ask once:

What decision are you trying to make? One sentence, phrased as a question.

Reject a topic disguised as a decision. "Bulk import" is a topic. "Should we prioritize bulk import for mid-market this quarter?" is a decision. If the user gives a topic, offer the sharpest decision question you can infer from it and ask them to confirm or correct it in one line.

Do not proceed past a vague decision. Everything downstream inherits the framing.

Step 2: Confirm sources, once

Look for evidence in this order and show the user what you found:

  1. The current folder and any evidence/, research/, interviews/, notes/, transcripts/ subfolder
  2. context/product.md, context/company.md, context/personas.md, context/competitors.md if they have content
  3. Connected MCP tools, if any are available (Jira, Slack, Confluence, Granola, GitHub)

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.
