Acumen: Skill for Claude Code

.agents/skills/workshop/SKILL.md

workshop is a skill for Claude Code from VGrss/Acumen. It costs 56 tokens per session (2,105 once invoked), scanned A, original, Apache-2.0.

A structured workshop for exploring many genuinely different ways to solve a product problem or opportunity before choosing a direction.

In plain words
What is it for?
Use it after identifying a problem to compare possible product shapes, remove duplicate ideas, challenge weak options, and select a direction.
Why use it?
It reduces the risk of committing to the first plausible idea or mistaking small variations for different solutions.

Skill for Claude Code

Written for Claude Code: user-invocable in frontmatter. Also seen: installed under .agents/ (shared by several agents).

This is VGrss/Acumen's own configuration. It tells Claude Code how to work on Acumen itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything Acumen configures →

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

workshop 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 2mo 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 — 171 lines — stays where its author put it; the contents beside it link to each section on GitHub.

MANDATORY PREPARATION

Invoke /product-thinking — it contains the Context Gathering Protocol and the AI Slop Test. Follow the protocol before proceeding.

Mindset

A workshop is divergence. Its one job: take a single problem or opportunity and expose the full range of shapes a solution could take — so the choice of shape is deliberate, not the first plausible idea.

The two failure modes:

  • First-idea lock-in. The team names a problem, pictures one solution, and scopes it. The workshop's job is to prove there were nine other shapes worth seeing first.
  • Ten variations of one idea. Producing "10 options" that all feel like the same product to a user is not divergence — it's padding. If two options would feel identical in the user's hands, they count as one.

This is not brainstorming. Brainstorming produces 40 ideas and zero decisions. A workshop produces genuinely different options and a recommended direction. Push back on weak options. Kill duplicates. The output is a clear map of the solution space plus a pointer to where to go next.

Input

A workshop needs one problem or opportunity to diverge on. It comes from:

  • /diagnose — a problem or opportunity it surfaced (the common path). Read the referenced report in .acumen/reports/.
  • .acumen/value-chain.md — an opportunity listed against an extension point in the value chain.
  • Directly stated — the user hands you a problem in the argument.

If the input is vague ("engagement is low"), sharpen it to a one-line problem statement before diverging — a fuzzy problem produces fuzzy options. If you cannot sharpen it from context, run /diagnose first and say so.

Context Pull

Load context as fuel for divergence, not to discover the problem (that was /diagnose's job):

  1. Product context. Read .acumen.md — thesis, positioning, stage, constraints. Options that dilute the thesis still belong on the board; flag them, don't hide them.
  2. Personas. Read .acumen/personas.md — whose problem this is, their workarounds, their daily workflow.
  3. Features. Read .acumen/features.md — what exists today that an option could repurpose, extend, or replace.
  4. Value chain. Read .acumen/value-chain.md — where in the workflow the problem sits and which adjacent steps an option could reach into.
  5. Competitors. Read .acumen/competitors.md — how others solve this shape of problem, and where the white space is.

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.
