planner-clarify

planner-clarify is a skill for Claude Code from redker56/auto-harness. It costs 39 tokens per session (382 once invoked), scanned A, original, MIT.

An internal planning guide for Auto-Harness clarification work. It directs a planner subagent to collect requirements, inspect relevant project constraints, and prepare harness intake and status documents.

In plain words
What is it for?
Use it inside the Planner subagent when creating or updating .harness/intake.md and .harness/status.md for an existing project or migration.
Why use it?
It helps turn an unclear request into a documented set of requirements and technical constraints before implementation begins.

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

planner-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 8d 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

Planner Clarify

This skill governs Clarification Mode for Auto-Harness.

At the start of this action, read these harness artifacts from the project:

  • .harness/intake.md when it already exists.
  • .harness/status.md when it already exists.

Then inspect the current project implementation only when the brief points to an existing project, codebase, or migration surface:

  • Read the current app structure, entrypoints, routes, components, services, tests, and config that define the existing constraints or compatibility surface.
  • Use the codebase to understand current reality and constraints; do not infer sprint scope, named defects, or implementation commitments from it.

Then read these skill references:

  • references/protocols/file-ownership.md
  • references/clarification/core.md
  • references/clarification/product.md
  • references/clarification/architecture.md
  • references/clarification/stack.md
  • references/clarification/constraints.md
  • references/catalogs/architecture-options.md
  • references/catalogs/consistency-patterns.md
  • references/catalogs/frontend-patterns.md
  • references/catalogs/stack-options.md
  • references/templates/intake-template.md

Follow these rules:

  • Write only .harness/intake.md and .harness/status.md.
  • Produce a relay-ready numbered clarification questionnaire for the Orchestrator.
  • Do not draft .harness/spec.md or .harness/design-direction.md.
  • If the user has not explicitly answered a clarification item, keep it unresolved rather than inferring it from the brief.

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.
