Use when writing, rewriting, or reviewing PR/CL descriptions, commit messages, or code-change summaries that explain what changed and why. TRIGGER on "write PR description", "improve this commit message", "summarize this diff", "CL description", "change…
Use when reviewing code, pull requests, patches, CLs, diffs, or proposed implementations for engineering quality, code health, design, functionality, tests, maintainability, specialist risk, or approval risk. TRIGGER on "review this PR", "code review",…
Use when a code hotfix, rollback alternative, production/security/legal fix, launch blocker, or hard external deadline claims expedited review or relaxed process. TRIGGER on "emergency change", "hotfix", "prod incident", "major security hole", "must ship…
Use when drafting, rewriting, classifying, or improving code review comments as a reviewer. TRIGGER on rough review notes, requests to make comments clearer or kinder, severity labels, "how should I phrase this review comment?", "write review comments",…
Use when handling code review feedback as the change author, addressing reviewer comments, drafting replies, resolving disagreements, or summarizing updates. TRIGGER on "address review feedback", "respond to this review comment", "reviewer asked", "I disagree…
Use when planning, splitting, shrinking, or sequencing large features, refactors, migrations, or pull requests into small reviewable PRs or CLs. TRIGGER on "split this PR", "this diff is too large", "stacked PRs", "change sequence", "reviewable chunks",…
Inventory everything an agent injects into each request besides the user's message, such as system prompt, environment info, skill list, tool definitions, per-turn context blocks and reminders, and check necessity, frequency, precision, position and…
Write a hand-off document so a fresh session or another person can continue the current task without the chat history. Use when switching tasks, after several compactions, before clearing a session, or when asked to write a handoff, brief, or progress doc.
Run a harness change as a controlled experiment, with a small end-to-end eval, one change at a time, repeated runs, and looking at flipped tasks, request count, tokens and cache hits, not just the average score. Use before and after changing prompts, tools,…
Review a code change from a clean context, the way an outside reviewer would. Use after the agent finishes an implementation, before merging, or when asked for an independent or second-opinion review of a diff.
Audit how an agent harness runs long shell commands, covering foreground wait limits, moving to background without re-running, timeouts, completion notification, polling, output size, cleanup and behaviour after compaction. Use when building or reviewing an…
Check how an agent or a working session handles long conversations, covering tool-result clearing, compaction, what gets written to files, when to start a new session, and how memory is scoped. Use when a long session starts forgetting constraints, after…
Decide whether a piece of work should go to a subagent or stay in the main agent loop. Use before spawning subagents, when designing a multi-agent architecture, or when auditing an existing set of subagents for merging back.
Audit how much context an agent's tools consume, through tool definitions and tool results, and decide whether to trim the catalog, add tool search, or add programmatic tool calling. Use when an agent has many tools or MCP servers, picks the wrong tools, or…
Review how an agent reached its result, not only whether the result passed, covering tools called, detours, unverified assumptions and wasted round trips, and turn the findings into concrete harness or prompt fixes. Use after an agent task finishes or fails,…
Replace with one sentence on what this skill does, then when the agent should use it. The agent decides whether to load the skill from this line, so be specific.
