Ran a real 'monolith vs microservices' decision baseline-vs-skill: both reached the same recommendation, but the skill run explicitly surfaced the unstated assumption (no confirmed scaling bottleneck) and stated a concrete condition that would flip the call -- baseline just gave a generic pros/cons list.
Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works
- Installs cleanly 5/5
- Triggers reliably 5/5
- Output vs. baseline 7/10
- Docs & honesty 5/5
What Overthink does
Defines 8 thinking modes (model, create, diagnose, verify, evaluate, decide, taste, synthesize) and has the agent build a private todo ledger picking and chaining the modes relevant to the task, reading one reference file at a time. Triggers on complex reasoning, decision-making, nuance, evaluation or communication-sensitive work, and explicitly says not to activate itself for simple, non-manually-invoked tasks.
How to install Overthink
git clone https://github.com/s0md3v/overthink
cd overthink
mkdir -p ~/.claude/skills
cp -r skill ~/.claude/skills/overthink
Skills live in ~/.claude/skills/ (global) or .claude/skills/
(per-project). Restart Claude Code after installing.

It also activates on plain-language prompts like these:
-
Should we migrate our 15-person startup's monolith to microservices? -
This decision is ambiguous and high-stakes, reason through it carefully -
Evaluate and decide between these two vendor contracts for me
Frequently asked questions
- Is the Overthink skill free?
- Yes. The skill itself is free from s0md3v/overthink. SkillProof publishes the install command and an independent test verdict at no cost.
- Does Overthink work with Claude Code?
- We tested it with Claude Code 2.x (agent harness) on Jul 14, 2026. Verdict: Tested · Works. Ran a real 'monolith vs microservices' decision baseline-vs-skill: both reached the same recommendation, but the skill run explicitly surfaced the unstated assumption (no confirmed scaling bottleneck) and stated a concrete condition that would flip the call -- baseline just gave a generic pros/cons list.
- What is the Overthink SkillProof Score?
- 8.8/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 7/10, docs & honesty 5/5.
- How do I install Overthink?
- Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.
- Can I use Overthink with Cursor, Copilot, Gemini CLI, Codex or other AI tools?
- The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.
