Evaluate the build trail of a PR — read the claude -p sessions the harness ran to build it, find where the project's context (Expert / AGENTS.md / skill / spec) served or failed the agents, then capture the learnings as evals (regression tests over the harness's own skills/context) and context fixes. Use when resolving a STUCK (diagnosis-first), auditing how a converged PR was built, or auditing a /learn memory PR. Human-driven and conversational — the trail-evaluating sibling of /evaluate-pr. Outcomes land on a branch (the PR's, or a fresh capture branch if you'll discard the PR) and reach memory via merge + /learn. Triggers - evaluate-sessions, evaluate sessions, review the build trail, diagnose stuck, audit how this was built, session observability.

Select and apply Patronum operators for Effector code with minimal, practical v2.x examples. Use when tasks involve choosing between Patronum operators, composing reactive state flows, replacing manual sample/combine boilerplate with Patronum utilities, explaining operator signatures and return types, or adapting legacy Patronum usage to modern v2 shorthand and import patterns.

Design, refactor, and review Effector state management using modern v23+ patterns. Use when tasks involve createStore/createEvent/createEffect modeling, dataflow with sample/attach/split, scope-safe SSR with fork/allSettled/serialize/hydrate, React integration with useUnit, Solid/Vue integration patterns, fixing scope loss, or replacing anti-patterns such as business logic in watch, imperative calls in effects, and direct getState business reads.

Resolve git conflicts (rebase, merge, cherry-pick, revert) using mergiraf, deterministic category handling, explicit intent inference, validation, and semantic-conflict auditing. Use when git status shows unmerged paths or an operation is paused with conflicts. Also decomposes an oversized PR or branch into smaller stacked PRs along functional/structural boundaries.

Implements and debugs browser Web Neural Network API integrations in JavaScript or TypeScript web apps. Use when adding navigator.ml checks, MLContext creation, MLGraphBuilder flows, device selection, tensor dispatch and readback, or explicit fallback paths to ONNX Runtime Web or other local runtimes. Don't use for model training, server-side ML inference, or cloud AI APIs.

Implements and debugs browser Prompt API integrations in JavaScript or TypeScript web apps. Use when adding LanguageModel availability checks, session creation, prompt or promptStreaming flows, structured output, download progress UX, or iframe permission-policy handling. Don't use for server-side LLM SDKs, REST AI APIs, or non-browser providers.

Authors and structures professional-grade agent skills following the agentskills.io spec. Use when creating new skill directories, drafting procedural instructions, or optimizing metadata for discoverability. Don't use for general documentation, non-agentic library code, or README files.

Operate AgentMail from a shell with the official CLI. Use when the user wants commands for listing or creating inboxes, reading or searching mail, sending or replying, managing drafts, or scripting JSON/YAML output; do not use for SDK code, MCP setup, or framework adapters.

Build with the AgentMail TypeScript or Python SDK for inbox, message, thread, draft, attachment, domain, allow/block list, pod, webhook, and WebSocket workflows, including programmatic agent sign-up, domain/DNS administration, and deliverability triage (bounces, spam, blocked mail). Use when implementing or reviewing AgentMail API code; do not use for direct mailbox operations, CLI usage, MCP setup, or framework-toolkit integration.

Use when working with MongoDB — designing a schema or collection (embed vs reference, data modeling, BSON types, schema validation), optimizing performance (indexes, ESR rule, explain() / slow query tuning, aggregation pipelines, covered queries), benchmarking or monitoring (profiler, mongostat, working set, executionStats), or applying standard practices (write/read concern, read preference, transactions, replication, sharding/shard keys, security, connection pooling). Covers MongoDB 8.0 with version-gated notes back to 4.x.

Treats bug-fix pull requests as invasive and untrusted. The agent must security-scan the PR first, must not run any command supplied by the author or issue, must reproduce the claimed bug on clean main with an agent-written repro, and must reject hunks that are not required to kill that bug. The agent must security-scan the PR first, then update the branch from latest `main`, pull CodeRabbit comments on an open GitHub PR, and write a root-cause section plus possible alternatives. Use when reviewing, approving, opening, or updating a fix PR, when the title or body is a bug fix, or when the user says /bugfix-pr, "review this fix", "is this bug real", or "prove this fix". Don't use for feat, chore, or docs PRs, commit messages, or style-only review of a change that is not a bug fix.

Review staged wiki writes and promote accepted pages to final locations when WIKI_STAGED_WRITES is enabled. Use for staging approval/commit; rejected pages return to _raw/ for editing.

Add volumetric underwater god rays to a Three.js scene, marching one drifting swell field along every view ray at half resolution so the light shafts converge on the sun, parallax with the camera and carry rippling caustic streaks, with a shimmering surface underside, a sun that wobbles through the ripples, and the same light dappling fish as they swim through the beams. Use for underwater scenes, oceans seen from below, aquariums, reefs, kelp forests, diving and shipwreck scenes, schools of fish, sunbeams or light shafts through water, caustics, "rays of light shining through the ocean", or watery ripples on a background. Includes a reusable module and the Blue Hour sardine-school demo.

Diagnose Pollinations model failures, error spikes, timeouts, and incorrect output using current gen/enter logs and Tinybird data. Use for incidents or specific failed requests; use model-management for catalog, routing, or pricing changes.
