A composable skill library that turns Claude Code or Codex into an orchestrator with parallel subagents, verification, and self-improving workflows.

Reduce negative-constraint and session-history leakage when a discarded proposal or user correction is echoed into final artifacts as a ‘without X’ label, rejected-option explanation, or process residue. Use for 此地无银三百两式 output in prose, code, metadata, and handoffs, including later requests to finish, commit, publish, or open a PR after iterative work; not for ordinary deletion, deprecation, migration, or requirements where the exclusion itself is material.

Steward the vanillagreencom/kendex issue queue (Linear team KEN is the poll surface; GitHub stays the PR/code surface) on a self-paced loop: watch open PRs, poll, triage (dedupe; close non-kendex issues and repost project-local ones to their owning repo; fix genuine defects in kendex's skills/agents/hooks/pi-extensions or the Rust CLI), run each fix through the orch skill, merge, propagate via kendex refresh, then reschedule. A thin wrapper: fix cycles belong to orch, PR mechanics to the github skill, PR monitoring to review-gate's pr-watch, Linear ops to the linear skill — this skill carries only the kendex-specific stewardship knowledge. Use when asked to monitor kendex's issues continuously or to run one fix-and-propagate cycle.

Scraping + AI-provider standards — the Scraper trait & SCRAPERS registry, selector resilience, rate-limiting/cancellation, and the provider-abstraction (zero-change) rule for embeddings/streaming/prompts. Load for changes under scraping/, ai_provider/, packages/prompts, documents/embed.

Resolve rebase and merge conflicts for an already-open Vigilante pull request, keep the branch validated, and report progress back to GitHub.

Orchestrate parallel implementation and fresh validation agents safely in the Sero repository. Use when a task asks for pi-subagents, parallel workers, isolated worktrees, review-and-fix loops, or several independent fixes that must be integrated and reviewed without Claude Code.

Select, probe, calibrate, and audit the Burger viscoelastic contact model for PFC 5.0 asphalt-mixture cases, including Maxwell-Kelvin parameter roles, units, temperature/rate dependence, PFC5 cmat assignment, timestep checks, creep/recovery validation, and PFC5-only syntax boundary checks.

Launch or connect to a local development web server and drive it with a reusable headless-Chromium command interface. Use when asked to render, smoke-test, interact with, verify, or screenshot a local frontend or HTML mockup.

Finalize an implemented rolling-wave slice for user review. Use when the user wants Codex to review the current branch state against a ready-for-review or in-review slice contract, confirm and fix required findings, repeat review and verification until no required findings remain, ask before accepting findings that materially change project shape or contradict project assumptions, record review state, and leave the clean slice in review for complete-slice.
