tune-rethink

tune-rethink is a skill for Claude Code from Jerry0022/dotclaude. It costs 224 tokens per session (2,368 once invoked), scanned A, original, MIT.

A structured reset for a development task or app area that has stopped improving after many rounds of changes.

In plain words
What is it for?
Use it to revisit goals, consider fresh directions, assess the current app, and choose and apply a new approach.
Why use it?
It helps break the habit of making small fixes based on an implementation that may be steering the work in the wrong direction.

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

tune-rethink 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.

How it starts

The opening of the file, as written. The whole thing — 213 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Tune Rethink — Strategic Reset

Break out of a stuck development loop for $ARGUMENTS: rebuild the goal picture, think fresh without being anchored by the current implementation, then reconcile, decide, and implement autonomously.

Why this skill exists: when the same area has been iterated on many times without reaching the goal, the current implementation itself anchors every new attempt. This skill enforces un-anchored ideation structurally — the ideation agents cannot read the code — and re-introduces existing knowledge only in a second, explicit step.

Step 0 — Load Extensions

Check for optional overrides. Use Glob to verify each path exists before reading. Skip missing files silently.

  1. Global: ~/.claude/skills/tune-rethink/SKILL.md + reference.md
  2. Project: {project}/.claude/skills/tune-rethink/SKILL.md + reference.md
  3. Merge order: project > global > plugin defaults

Step 1 — Intake & Scope

$ARGUMENTS names the target — the whole app or a section of it. The rethink is holistic for the named target (not a micro-polish of one control).

  • If $ARGUMENTS is empty: ask ONE question (AskUserQuestion) to name the target before anything else.
  • State the scope boundary explicitly: "In scope: X including Y. Out of scope: Z." This boundary travels with the brief through every later step.

Step 2 — Evidence Mining (self-served)

Build your own picture BEFORE asking the user anything. Two source classes:

  1. Repo evidence: git log for the target area, open/closed issues, existing concept pages, docs, CHANGELOG, CLAUDE.md. Reconstruct: what was the intended goal, what was already tried, where did iterations circle.
  2. Live evidence: look at the running app — this is the only honest source for "it doesn't look/feel right". Follow {PLUGIN_ROOT}/deep-knowledge/test-autonomy.md and preview-testing.md: start the app (Claude Preview preferred), view the target at the profile viewports (responsive-testing.md), click through its core flows, capture snapshots.

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.

tune-rethink is a skill published in the GitHub repository Jerry0022/dotclaude (5 stars, last pushed yesterday), licensed MIT. It adds 224 tokens to every session and 2,368 once invoked, about $0.0011 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 2026-08-31.
