st-refine-plan

st-refine-plan is a skill for Claude Code from e0ipso/strikethroo. It costs 81 tokens per session (1,354 once invoked), scanned A, original, MIT.

A plan-refinement workflow for an existing Strikethroo plan identified by its numeric ID. It reviews the plan, asks about missing decisions, and updates it according to the answers.

In plain words
What is it for?
Use it to review, improve, pressure-test, or update an existing plan in an initialized Strikethroo workspace.
Why use it?
It helps find gaps or weak assumptions in a plan before implementation starts.

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

st-refine-plan 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 yesterday.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/check-for-updates.cjs, scripts/find-strikethroo-root.cjs, scripts/validate-plan-blueprint.cjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

st-refine-plan

Inputs

The user supplies the numeric plan ID conversationally, plus any optional refinement notes.

Operating Procedure

1. Locate the strikethroo root

Run scripts/find-strikethroo-root.cjs from the user's working directory. If it exits non-zero, stop and ask the user to run npx strikethroo init.

Treat the path it prints as <root> for every subsequent step.

Delegated execution workers skip this step and do not emit update notices.

Run scripts/check-for-updates.cjs "<root>" as a separate command using this skill's script path. Keep the user's working directory. Read the one JSON line on stdout. When notice is present, retain its exact text for the final user-facing response. Never pause for permission and never run an update.

2. Resolve the plan

Run scripts/validate-plan-blueprint.cjs <plan-id> planFile for the plan file's absolute path. Another field name prints that field instead.

If the script exits non-zero, stop and ask the user to confirm the plan ID. Do not guess a different ID.

3. Load project context

Read <root>/config/STRIKETHROO.md for this project's directory conventions. Read <root>/config/hooks/PRE_PLAN.md and execute its instructions before proceeding. Read <root>/config/templates/PLAN_TEMPLATE.md; the refined plan must still conform to it. Read <root>/config/shared/clarification-gate.md and apply it in the Clarification Loop.

4. Baseline Review

Read the entire plan end-to-end without modifying it. Record every contradiction and every gap you find under these lenses:

  • Context gaps: missing background, assumptions, competing priorities.
  • Technical gaps: underspecified architecture, unclear interfaces, missing diagrams.
  • Risk gaps: untracked risks, missing mitigations, hand-wavy success metrics.
  • Scope issues: gold-plating, ambiguous boundaries, requirements that contradict YAGNI.

Document each one as {section, issue, severity, proposed fix}.

5. Clarification Loop

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.

Owns the opening move of first-run when the user has NOT handed you a substantive prompt (cold start), and sets the voice-vs-text opening posture for any open. Shows a provisional dream and a guess about who the user is, then learns from their correction (show-to-learn) and re-aims. Hands back to the first-run spine…

disqualification

The honest exit. Loads when qualification signals sustained-low or a realism failure (the ask is genuinely outside QB's wheelhouse). Acknowledges the mismatch plainly, suggests a realistic alternative, preserves dignity, and does not chase. A legitimate designed outcome, not a framework failure.

qualification

Reads qualification signals from the user's input and passive context, sets the archetype and effort mode, and decides whether to proceed up the convince ladder or route to the disqualification skill. Runs alongside the first-run spine from the first substantive message onward. Falls back to "proceed at normal effort"…

Owns the build wait and build failure. Narrates the generation honestly while it runs, and when it errors, names the failure plainly with a real recovery path instead of a generic "oops". Loads when generation is long or returns an error. The single highest-risk moment for the "it's actually building" belief.
