Claude Code coding skills

An opinionated Claude Code plugin marketplace with eight workflow skills for disciplined planning, proof-based review, clean commits, and multi-session Technical Project Plans (TPPs). Documented in depth at photostructure.com/coding.

Skill	What it does	Read more
replan	Iterative critique-and-refine planning. Forces multiple passes before committing to a design.	Claude picks the first idea that works. Make it pick the best one.
review	Code review that requires proof before reporting — a short list of real bugs, not noise.	Most AI code reviews are noise. Here's how to fix that.
review-staged	The same proof-based review, scoped to git diff --cached, then drives a clean commit.	Most AI code reviews are noise. Here's how to fix that.
gitplan	Untangle a large working tree into coherent, single-purpose Conventional Commits.	—
stage	Stage only the hunks the current session touched — never the whole file — and commit cleanly.	—
tpp	Work on a Technical Project Plan: read the plan, do the current phase, record discoveries. Bundles a reference TPP-GUIDE.md.	Claude Code has amnesia. So do PRs, changelogs, and your future self.
handoff	Update the active TPP before context runs out, so the next session continues instead of restarting.	Claude Code has amnesia. So do PRs, changelogs, and your future self.
tpp-orchestrate	Execute a queue of TPPs serially: TDD subagents, dual independent reviews, every finding vetted against ground truth, one commit per plan.	Claude Code has amnesia. So do PRs, changelogs, and your future self.

Adapting

These skills are intentionally generic. Each SKILL.md ends with an "Adapting for your project" note — point them at your CLAUDE.md/AGENTS.md, add domain-specific critique or review checks, and tune the strictness to taste.

Further reading

The thinking behind these skills, on photostructure.com/coding:

• Claude picks the first idea that works. Make it pick the best one. — why replan exists: defeating Claude's tendency to satisfice.
• Most AI code reviews are noise. Here's how to fix that. — the proof-before-reporting rule behind review and review-staged.
• Claude Code has amnesia. So do PRs, changelogs, and your future self. — Technical Project Plans, the system behind tpp, handoff, and tpp-orchestrate.
• The LLM sycophancy antidote — making Claude push back instead of agreeing.
• If something is odd, inappropriate, confusing, or boring, it is probably important. — a code-review philosophy.
• Uncertain, lazy, forgetful, & impatient: it's what you want your code to be. — the design values these skills enforce.

Versioning

plugin.json has no version field, so while this marketplace is hosted in git every commit counts as a new version and /plugin update picks up changes automatically. Add an explicit version once you want stable, opt-in releases.
