Reverse-generate OpenSpec capability specs (openspec/specs/<cap>/spec.md) from code that lacks them, or reconcile an existing stale spec with `--refresh`, using parallel subagents. Fans out one blind generator per capability, audits each spec against the code for hallucinations, and promotes only on user confirm. Use on "generate specs from code", "backfill openspec specs", "refresh a stale spec".

blackbelttechnology Skill

Diagnose/fix worktrees missing the generated openspec-* (opsx) skills after worktreeInit. Root cause: bare `npx openspec` can resolve a squatted registry stub instead of the real CLI.

blackbelttechnology Skill

Run before scaffolding any OpenSpec proposal to catch duplicates of archived work and contradictions with shipped architecture. Always run when about to create openspec/changes/<name>/, especially for proposals touching a subsystem with a recent archive entry. Triggers: 'scaffold OpenSpec', 'write a proposal', 'create change', 'openspec change new'.

daedalus Bundle

Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, edit or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy. Make sure to use this whenever the conversation hints at making something reusable, turning a workflow into a system, or formalizing a process.

daedalus Skill

Converts any post, thread, article, paper, video transcript, technique, workflow, or methodology into a robust production-quality SKILL.md. Extracts the underlying insight, workflow, assumptions, and validation criteria; drafts a skill; then dogfoods and patches it through 2–6 rounds until behavior stabilizes. Use whenever the user says "turn this into a skill", "create a skill from this post/technique/paper", "make a skill for X I just read", "dogfood this", or pastes/links content and wants to operationalize it. Also trigger when the user describes a multi-step technique they've seen elsewhere and wants to capture it as a reusable capability.

daedalus Bundle

Rewrite all commit authors and committers in a git branch or repository history to a new name/email combination. Use this skill whenever the user mentions changing git commit authors, rewriting git attribution, mass updating committer info, fixing author names/emails across a branch history, or wants to correct commit attribution for an entire repo. Trigger even if the user doesn't explicitly mention "git-author-rewrite" or uses casual phrases like "change who wrote these commits" or "update my email on all past commits".

daedalus Skill

Design, refine, and evolve structured skills from user intent. Use this whenever a user wants to turn a workflow, capability, or idea into a reusable system, improve an existing skill, or formalize how something should be done repeatedly. Trigger even if the user is vague (“make this reusable”, “turn this into a system”, “optimize this process”).

daedalus Skill

Apply Kent Beck's Canon TDD workflow when implementing new features, fixing bugs, or any task involving writing or changing code behavior. Use this skill whenever the user wants to do TDD, test-driven development, write tests first, red-green-refactor, or asks how to implement something in a test-driven way. Also trigger when the user mentions "make it pass", "write a failing test", or wants to build something incrementally with tests. Do NOT skip this skill just because the task seems simple — Canon TDD applies to even small changes.

daedalus Skill

Systematic workflow for optimizing a Python project's runtime performance, memory footprint, or startup time. Use whenever the user asks to make Python code faster, reduce memory usage, profile a Python project, fix slow tests/CI, or generally "optimize" a Python codebase. Always measure before and after changes — never optimize on vibes. Covers profiling (cProfile, py-spy, memray, line_profiler), algorithmic fixes, C-extension/native acceleration (Cython, Numba, Rust via PyO3), concurrency (asyncio, multiprocessing, GIL/free-threading), memory optimization (__slots__, generators, numpy), and packaging/startup optimization.

daedalus Skill

Full Python project bootstrapping workflow. Use this skill whenever the user wants to build a new Python tool, library, CLI, or module from scratch — especially when they mention "create X", "build X in Python", "write a Python project for X", or ask for a proper project with tests, linting, versioning, or git setup. Triggers on any request to scaffold, initialize, or structure a new Python project. Even if the user only says "build me X in Python", apply this skill — it encodes the full professional workflow: SPEC → implementation → pytest → README → lint → git. Always use this skill rather than improvising a one-off script when the deliverable is a reusable project.
