planner-spec-draft-parallel

planner-spec-draft-parallel is a skill for Claude Code, Codex from redker56/auto-harness. It costs 49 tokens per session (487 once invoked), scanned A, original, MIT.

An internal planning helper for an Auto-Harness workflow, where a project is prepared through shared planning files. It drafts a technical specification and a design direction in parallel.

In plain words
What is it for?
Use it inside the Planner subagent to update intake notes and produce or revise the project specification and visual design direction.
Why use it?
It keeps planning decisions, existing project constraints, and draft documents aligned during the planning stage.

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-spec-draft-parallel 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 5d 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 Spec Draft Parallel

This skill governs Spec Draft Mode for the parallel Auto-Harness workflow.

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

  • .harness-parallel/intake.md
  • .harness-parallel/status.md
  • .harness-parallel/spec.md when revising an existing spec.
  • .harness-parallel/design-direction.md when revising an existing design direction.

Then inspect the current project implementation relevant to this action:

  • Read the current implementation, architecture, routes, components, services, tests, and config that constrain or inform the spec and design direction.
  • Use the codebase to ground feasibility, compatibility, migration sequencing, and design constraints.

Then read the same reference files used by skills/planner-spec-draft/, including its file-ownership protocol, spec template, design-direction template, and status-board template. Apply those rules to .harness-parallel/ paths.

Follow these rules:

  • Update .harness-parallel/intake.md first so it stays the durable decision log.
  • Ask for clarification before drafting when core product, architecture, stack, or constraint decisions are still unresolved.
  • Then write or revise .harness-parallel/spec.md and .harness-parallel/design-direction.md.
  • Keep workflow_mode=parallel in .harness-parallel/status.md.
  • Use pending_action=spec_approval_parallel when the spec is ready for user approval.
  • Do not read or write .harness/.
  • Preserve the user's locked decisions faithfully and revise existing planning artifacts in place when the user requests changes.
  • Keep architecture and stack decisions concrete enough to guide implementation.
  • Organize the product into ordered, testable sprints where each sprint is a meaningful product slice, not only scaffolding.
  • Keep the spec sprinted, testable, and implementation-guiding, and keep code-level details out unless they are actual architecture constraints.
  • Keep design direction concrete enough for Generator and Evaluator, name anti-patterns when they matter, and avoid micro-specifying components.

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.

planner-spec-draft-parallel is a skill published in the GitHub repository redker56/auto-harness (14 stars, last pushed 4mo ago), licensed MIT. It adds 49 tokens to every session and 487 once invoked, about $0.0002 per session on Opus 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 2026-08-30.
