review-feedback-schema
existential-birds
Schema for tracking code review outcomes to enable feedback-driven skill improvement. Use when logging review results or analyzing review quality.
pydantic-ai-common-pitfalls
existential-birds
Avoid common mistakes and debug issues in PydanticAI agents. Use when encountering errors, unexpected behavior, or when reviewing agent implementations.
tdd
udecode
Use when implementing complex logic that needs test coverage - write the test first, watch it fail, write minimal code to pass; ensures tests actually verify behavior by requiring failure first; NOT for UI components, simple CRUD, or straightforward code
changelog
udecode
Use when updating CHANGELOG.md. Enforces consistent formatting with bolded item names, dash separators, and specific section ordering.
learn
udecode
Continuous learning system that extracts reusable knowledge from work sessions. Triggers: (1) /learn command to review session learnings, (2) "save this as a skill" or "extract a skill from this", (3) "what did we learn?", (4) After any task involving non-obvious debugging, workarounds, or trial-and-error discovery. Creates new Claude Code skills when valuable, reusable knowledge is identified.
trace
udecode
Use when errors occur deep in execution and you need to trace back to find the original trigger - systematically traces bugs backward through call stack, adding instrumentation when needed, to identify source of invalid data or incorrect behavior
re-frame2-pair-retro
day8
Retrospect on a re-frame2-pair session and turn it into prioritised improvement ideas for the pair skill, preload runtime, MCP surface, or upstream re-frame2 Tool-Pair contract; optionally drafts a GitHub issue the user can file. Not for ordinary re-frame2-pair operation, nor for the code/spec/framework work the body's routing matrix sends elsewhere. Requires evidence: a concrete re-frame2-pair session in this conversation (turns where the user attached, dispatched, walked traces/epochs, hot-swapped, or time-travelled), or a user-supplied recap — vocabulary alone ("retro", "what went wrong", "any improvements?") does not justify activation. Two triggers: (a) explicit pull — "retro on this pair session", "review my re-frame2-pair session", "draft an issue about that"; or (b) post-error inside a pair session — after a stack trace, a pair tool returning {:ok? false :reason :error-kind}, or an :rf.error/ or :rf.epoch/restore- trace during live pair work.
re-frame2-pair
day8
Pair-program against a running re-frame2 application via its Tool-Pair contract — attach to a live shadow-cljs nREPL, inspect a frame's app-db, dispatch events, hot-swap handlers, read the trace stream and per-frame epoch history, time-travel with restore-epoch, and replay a retained epoch strictly with replay-epoch. Use when the user is operating on (or wants to operate on) a live runtime they have running locally. Do not use for static spec reading, architecture questions, design discussion, or ordinary source edits when no runtime is involved — those belong to skills/re-frame2/ (authoring) or direct spec reading. See references/vocabulary.md for the surface glossary; vocabulary matches alone do not justify activation.
rust-development
thrashr888
Rust development workflow with quality gates, testing, and iteration patterns. Use when developing Rust code, running tests, or iterating on Rust projects.
rust-best-practices
thrashr888
Rust coding best practices for idiomatic, efficient, and maintainable code. Use when writing Rust code, reviewing code, or learning Rust patterns.
twd-tester
BRIKEV
TWD test runner agent — runs in-browser tests via twd-relay, reads failures, fixes issues, and re-runs until green. Use when you want to execute and validate existing TWD tests.
plain-bug
dropseed
Submit a bug report for the Plain framework. Use when you encounter a bug, error, or unexpected behavior. Collects context and creates a GitHub issue.
plain-upgrade
dropseed
Upgrades Plain packages and applies required migration changes. Use when updating to newer package versions.
effect-best-practices
forcedotcom
Enforces Effect-TS patterns for services, errors, layers, and atoms. Use when writing code with Effect.Service, Schema.TaggedError, Layer composition, or effect-atom React components.
vscode-window-messages
forcedotcom
Guidelines for using vscode.window.show*Message methods. Use when working with showInformationMessage, showWarningMessage, showErrorMessage.
verification
forcedotcom
Verification steps for code changes. Use after ANY code change to ensure quality, or when creating plans because those should include verification steps.
ts4023-effect-errors
forcedotcom
Fix TS4023 errors when exporting Effect-based functions. Use when TypeScript reports "has or is using name 'X' from external module but cannot be named" for Effect error types, or when knip flags error type exports as unused.
gus-cli
forcedotcom
Interact with the Gus Salesforce org via CLI (sf). Query, create, update work items; query team epics. Use when user mentions Gus, work items, epics, or GUS/Git2Gus workflows.
research-debug
iamseungpil
Research-driven debugging workflow that combines web research for similar cases, deep code analysis with task-planner-analyzer, and iterative fixes with modular-code-architect and code-reviewer. Use when encountering training collapse, gibberish generation, or architecture-level bugs where the problem may be documented in research literature. Parallel execution of research and fixes for efficiency.
sentry-issue-resolver
Arctuition
"Analyze and resolve Sentry issues by fetching detailed issue information, performing deep root cause analysis, and providing actionable solutions. Use when the user asks to: (1) Analyze a Sentry issue, (2) Debug or investigate a Sentry error, (3) Fix a Sentry issue, (4) Get root cause analysis for application errors, (5) Resolve Sentry alerts. Works with Sentry URLs to fetch stack traces, error context, and event data."
