Use `uv` instead of `pip` / `python` / `venv` for Python work in repos that have adopted uv. Use when running Python scripts (`uv run`), adding dependencies (`uv add`), creating standalone scripts with inline dependency metadata (`uv init --script`), or managing the Python build backend (`uv_build`). Triggered by mentions of `uv`, inline script metadata blocks (`# /// script ... ///`), `uv.lock`, `pyproject.toml` with `[tool.uv]`, or any Python script Claude is about to run in a uv project.

sontek Skill

Diagnose bugs scientifically: reproduce, form a hypothesis, run a falsifying experiment, identify the root cause, then fix it and add a regression test. Use for "debug this", "why isn't this working?", flaky/intermittent failures, "can't reproduce", or "find the root cause". Unlike fix-issue, debug is for cases where the cause is not yet known.

sontek Bundle

Fetch and analyze Sentry data — issues (grouped errors), events (individual occurrences with stack traces and breadcrumbs), transactions, and logs. Use when the user asks to "look at Sentry", "fetch this Sentry issue", "find errors in Sentry", "search Sentry events", "what happened in Sentry around <time>", "get the latest event for issue X", or wants Claude to investigate a production error using Sentry data. Authenticates via `~/.sentryclirc`. Composes with review-code / iterate-pr (e.g., debug a Sentry issue, then produce a fix PR).

sontek Skill

Interview the user to resolve ambiguity in a request, plan, or design before committing to work — one targeted question at a time until intent, scope, and constraints are pinned down. Use when a request is underspecified, could have multiple valid interpretations, hides a false premise, or the user wants to stress-test a plan. Triggers on "clarify this", "grill me", "stress-test my plan", "get grilled on my design", "what am I missing", or any request vague enough that proceeding would mean guessing. Pairs with plan-implementation for pre-planning requirements clarification.

sontek Skill

Write a structured handoff document so a fresh Claude Code session can continue the current work without re-reading the entire transcript. Use when asked to "hand off", "handoff", run "/handoff", prepare for a "/clear", start a fresh session without losing context, or save the current conversation's state for a future session. Produces a local `HANDOFF_<slug>.md` (or `/tmp/HANDOFF_<slug>.md` outside a repo) that the user pastes or opens in the new session.

Pull Request

arcblock Skill

Take ONE thing from wherever it is all the way to merged. Accepts a work DID, Change Set @ sha, a GitHub issue/PR number or URL (projection alias), several of them, or nothing at all (the thing being discussed right now, or stated in the invocation). Resolves via /work first, proves it is a single coherent piece of work, then routes: an epic goes to epic-conductor; a Change Set/PR skips to review + gate + merge; a plain work item gets an isolated implementer, an independent clean-context reviewer, the repo's verification gate, and a merge. Files the work first when none exists. This skill ORCHESTRATES existing skills — it never reimplements review, gating, or epic decomposition. Use when you want one instruction to finish something.

arcblock Bundle

Independent clean-context review of ONE open GitHub pull request — read PR diff + linked issue + verify every claim against live code/tests + obtain a current verification fact through the pre-merge entrypoint and diagnose its root-cause + detect conflicts with sibling PRs, then emit an evidence-backed merge-readiness verdict (MERGE / COMMENT / SUPERSEDE / BLOCK / CLOSE). Every review invokes the entrypoint; a shared broker may single-flight and reuse only an exact current fact. --post writes one verdict comment. Never auto-merges (that gated step belongs to pr-sweep). Use /agentloop:pr-review <pr#> for a single PR; pr-sweep batches this engine across all open PRs.

arcblock Skill

Create standardized Pull Requests for blocklet projects. Performs lint checks, unit tests, version updates, and creates PRs following PR templates. Use `/blocklet-pr` or say "help me submit a PR", "create pull request" to trigger.

Manage skills from local paths or git repositories - add, update, or remove skill tips in ~/.claude/skills with group-skillname format

arcblock Bundle

After a merge or when ending multi-branch work: switch the primary checkout to the default branch, fast-forward from origin, then remove local worktrees and branches that have no unique work left. Use when the user says "切回 main 清理", "清理 worktree", "prune branches", "git hygiene", "收工清分支", or after confirming a PR merged. Safe by default: never delete a branch or worktree that still has commits not on origin/<default> unless squash-merge parity is verified. On explicit request ("这些是不是该补 PR"), also does a provenance investigation on each KEPT branch — merged-elsewhere / superseded / actively-tracked-via-open-PR / genuinely-orphaned — with a content-level redundancy check (not just commit-count) before rebasing and opening a belated PR for anything confirmed still-unique. Works in any git repo.

sontek Skill

Implement a fix for a bug, issue, or failing behavior from scratch, reproduce-first. Use when asked to "fix this bug", "fix this issue", "resolve

sontek Bundle

Cache and refresh remote git repositories under `~/.cache/checkouts/<host>/<org>/<repo>` so future references reuse a local copy instead of re-cloning. Use when the user references a remote git repository — full URL (`https://github.com/foo/bar`, `git@github.com:foo/bar.git`), `owner/repo` shorthand, or asks Claude to "look at", "read", "search", or "find something in" an external repo by name. Returns a stable local path that downstream skills (review-code, grep, Read) can use directly.

sontek Bundle

Iterate on a PR until CI passes. Use when you need to fix CI failures, address review feedback, or continuously push fixes until all checks are green. Automates the feedback-fix-push-wait cycle.

sontek Skill

Review a plan for architectural, DRY, scope, and UX concerns before implementation starts. Covers IMPLEMENTATION_PLAN_*.md / REFACTOR_PLAN_*.md files AND in-conversation plans drafted in Claude Code plan mode (ExitPlanMode) or inline messages. Use when user asks to "review the plan", "analyze the plan", "critique the plan", "is this plan good", or wants a senior engineer / product manager pass over a planning document. For creating a plan from scratch use plan-implementation or plan-refactor. For reviewing code or a PR use review-code.

sontek Skill

Create git branches following naming conventions. Use when creating new feature branches, bug fix branches, or any branch for development work. Defines the branch naming standards used across commit and PR skills.

sontek Skill

Apply performance improvements with before/after benchmarks. Use when asked to "optimize this", "make it faster", "speed this up", "profile and fix", or when the user wants perf fixes applied (not just reviewed). Runs `review-perf` to find candidates, then for each fix writes a benchmark, applies the change, re-measures, and reverts on regression. Companion to `review-perf` (which only finds issues); distinct from `auto-review-code` (which applies generic fixes without wall-clock measurement).

sontek Skill

Create a local REFACTOR_PLAN_<name>.md through a user interview, decomposing behavior-preserving restructuring into tiny commits. Use for "plan a refactor", "restructure this code", "extract a module", or tiny-commit refactor planning. Use plan-implementation for NEW features or phased additions, and review-plan for an existing plan-mode draft.

sontek Skill

Review EXISTING code at module/package scope for coupling, abstraction depth, seams, testability, and scalability; return a verdict and prioritized concerns. Use for "design review this module", "is this too coupled?", or "will this scale?". Use review-code for diff defects, review-plan for plan documents, and improve-architecture for codebase-wide redesign ideas.

sontek Skill

Review changed code for AI-generated slop and apply fixes. Use when the user says "simplify", "clean this up", "deslop", "tidy up", or after AI-generated code lands. Fans out to focused code-quality lane detectives (comments, structure, typing, complexity, defensive), coalesces their findings, and applies the safe ones.

zate Skill

Install, upgrade, or verify ctx persistent memory system

zate Skill

Query ctx memory and inject results into context

zate Bundle

This skill should be used when the user asks to "clean up memory", "sync ctx and memory", "review memory", "deduplicate nodes", "fix memory conflicts", "ctx cleanup", "memory maintenance", "reconcile memory systems", or mentions stale nodes, memory bloat, or keeping ctx and MEMORY.md in sync.

arcblock Bundle

Automated phase-by-phase implementation with a verification loop — drive a multi-phase build plan one phase at a time, each phase implemented then verified (static + dynamic + adversarial) before advancing. Use to execute a phased implementation plan (tasks.md) autonomously.

arcblock Skill

Analyze code changes to find related areas that may also need modification. Supports uncommitted changes, specific commits, commit ranges, and branches. Use before committing or opening a PR to catch missed updates.

arcblock Skill

Iterative clean-context review of a design/plan document or issue — spawn independent-perspective reviewers each round, score, and synthesize findings without carrying prior-round bias. Use to review an implementation plan, architecture doc, or design proposal before building.

arcblock Skill

Git branch management tool. Detects main iteration branch and branch naming conventions, handles branch creation and switching. Referenced by blocklet-dev-setup, blocklet-pr, and other skills.

arcblock Bundle

Form dispatchable epics out of unassigned open issues. Where issue-sweep triages ONE issue that a human replied to, and epic-conductor drives an epic that already exists, this skill fills the gap between them — it clusters unclaimed issues by defect layer, measures each cluster's file-level path surface against every in-flight epic, and emits epics that several agents can work in parallel without colliding. Disjointness is three-state (disjoint / overlap / unproven); an issue whose body names no files is NOT proven disjoint and must have its landing files located in code before dispatch. Keeps an incremental ledger so each run only reclassifies what changed. Produces epics only — it never dispatches, never merges, never touches existing epics.

arcblock Skill

Configure development environment for blocklet-type repositories. Supports parsing GitHub Issue URLs, Blocklet URLs, or problem descriptions to automatically locate repositories, check permissions, clone code, install dependencies, and start development server. Use `/blocklet-dev-setup` or say "help me fix the xxx blocklet issue", "I want to develop xxx blocklet", "I want to modify code related to this URL" to trigger. In short, use this as the starting point when you want to develop a blocklet.

sontek Skill

Automatically iterate review-code and code-simplifier until no more safe fixes remain. Use when user wants to "auto-review-code", "auto-fix", run review-and-simplify on repeat, or clean up code without staying in the loop for each finding. Auto-applies local, low-risk fixes; batches risky changes for a single end-of-run approval pass.

sontek Skill

Automatically iterate review-plan against a plan until no safe blocking edits remain. Use when user wants to "auto-review-plan", "auto-fix the plan", tighten a plan without staying in the loop for each finding, or harden an `IMPLEMENTATION_PLAN_*.md` / `REFACTOR_PLAN_*.md` / plan-mode draft before implementation. Auto-applies small, concrete blocking edits; batches structural recommendations for a single end-of-run approval pass.

sontek Skill

Collaborate in a live Hunk diff-review session: address the user's inline hunk notes, or walk through a changeset by steering the view and adding explanations. Use for "address my Hunk notes", "fix what I flagged", or "walk me through this diff". Unlike review-code/review-pr, this is interactive; unlike auto-review-code, it keeps the user in the loop.

sontek Skill

Create a local IMPLEMENTATION_PLAN_<feature>.md for NEW features, complex additions, or multi-phase work, with reconnaissance, binary ideal-state criteria, premortem, phases, and quality gates. Use for "create an implementation plan". Use plan-refactor for behavior-preserving restructuring, and review-plan for an existing plan-mode draft.

sontek Bundle

Explore a codebase to find opportunities for architectural improvement, focusing on making the codebase more testable by deepening shallow modules. Use when user wants to improve architecture, find refactoring opportunities, consolidate tightly-coupled modules, or make a codebase more AI-navigable.
