handbook: Skill for Claude Code

.claude/skills/clarify/SKILL.md

clarify is a skill for Claude Code from nicograef/handbook. It costs 49 tokens per session (326 once invoked), scanned A, original, MIT.

A clarification workflow that resolves unclear requirements through structured questions before work begins.

In plain words
What is it for?
Use it for thorough specification gathering, disambiguating any kind of task, and confirming critical decisions before implementation.
Why use it?
It prevents the agent from silently choosing assumptions when important decisions are still unresolved.

Skill for Claude Code

Written for Claude Code: installed under .claude/.

This is nicograef/handbook's own configuration. It tells Claude Code how to work on handbook 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 handbook 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

clarify 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 2d 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.

What it actually says

Clarify

Never act on an unresolved ambiguity. Resolve it by reading, then by deciding, and only then by asking.

  • Resolve unknowns through structured questions: walk each decision-tree branch, resolve dependencies between decisions one by one.
  • create-plan and write-prd embed a lighter clarification pass scoped to their own work.
  • Invoking this skill does not make every unknown a question. Each one still passes the ask gate; the ones that resolve to a single option are decided, not asked.

Workflow

  1. Ask in rounds, biggest unknowns first — ambiguous or underspecified parts of the request — per the clarification question rules. Every question clears the ask gate first.
  2. Drill deeper on prior answers: remaining gaps, edge cases, conflicting constraints. Confirm critical decisions before proceeding.
  3. Update the current plan or document with every decision made, then proceed with the task.

Constraints

  • Do not repeat questions the user has already answered.
  • Never act on an unresolved ambiguity — get an answer or record a documented Assumption first.

Changes

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.
