Run the pragmatic-skeptic 'ponytail' reviewer over the current diff to surface over-engineering — code, abstractions, dependencies, files, or process steps the problem does not need. Read-only and advisory; never trims safety, security, accessibility, data-loss handling, or their tests. Use before pushing a PR, when a change feels heavier than the task warranted, or when boilerplate/a new dependency crept in. Triggers: 'ponytail review', 'is this over-engineered', 'what can I delete here', 'did I over-build this'.
Use this skill to run a structured user-discovery interview for Caro and save the transcript into docs/discovery/transcripts/ under the project's anonymization rules. Use when a new product line or major feature spec needs to clear Gate 1 of .claude/rules/validation-discipline.md (the 20-transcripts rule). Also use to synthesize transcripts into the hypothesis ledger after each batch of 5 interviews. Triggers - "run a discovery interview for <feature>", "log this user conversation as a Caro discovery transcript", "synthesize this week's transcripts into the hypothesis ledger".
Safely reclaim disk space in the caro project. Cleans Rust build cache, stale git worktrees (both .claude/worktrees/ and .worktrees/), empty stubs, and node_modules using a tiered audit that preserves any worktree with uncommitted changes, missing remotes, or a lock file. Use when du shows the project > 30 GB or disk free is low.
DEPRECATED 2026-05-16 — use caro-shell instead. This skill recommends the --backend claude flag and a ~/.config/caro/config.toml path that do not work on the current caro 1.4.0 binary, and its 522-line educational body is 4× the size of caro-shell for no benefit to an agent. Will be removed after 2026-08-01.
Use this skill when the user needs a POSIX shell command synthesized from natural language — "how do I find/grep/awk/find files modified in the last hour", "kill the process on port 3000", "tar this up excluding .git", or any other terminal-task-as-prose. Shells out to the `caro` CLI for safety-validated command inference and presents the suggestion for explicit approval. Refuses to execute the command itself.
Build, render, ship, AND MAINTAIN the caro landing-page demo video using Remotion. Use when creating, updating, re-rendering, extending the project demo MP4 at website/public/caro-demo.mp4 — or when responding to a drift alert from the caro-demo-drift CI workflow or a beads task with label `caro-demo-video`.
Scaffold a new CaroML task file (.caro) from a natural-language description. Use this when the user wants to create a repeatable shell task that Caro will validate, generate, and maintain over time. Triggers on requests like "make a CaroML task that...", "scaffold a runbook for...", "create a .caro file for...", or invocations of `/caro new <name>`.
Understand how Spec Kitty manages git: what git operations Python handles automatically, what agents must do manually, worktree lifecycle, auto-commit behavior, merge execution, and the safe-commit pattern. Triggers: "how does spec-kitty use git", "worktree management", "auto-commit", "who commits what", "git workflow", "merge workflow", "rebase WPs", "worktree cleanup", "safe commit". Does NOT handle: runtime loop advancement (use runtime-next), setup or repair (use setup-doctor), mission selection (use mission-system).
