Skill Codex
Explains Jack Wotherspoon's Humans vs Slop talk and helps create quality gates for AI-heavy software work: review-cost analysis, slop detection heuristics, durable-value metrics, and human-judgment checkpoints. Use when the user asks about AI-generated maintenance burden, review economics, or preserving taste in…
Skill Codex
Review Harness Engineering diffs, PRs, commits, and readiness claims for introduced risk. Use when correctness, validation proof, security posture, traceability, closure safety, or review-thread resolution must be assessed before merge or handoff.
Skill Codex
Explore Harness Engineering options, filter ornate or weak ideas, recover dropped leverage, and select survivor routes before commitment. Use when intent, stage choice, tradeoffs, idea quality, or possible solution shapes are still unsettled before spec, plan, Linear, or implementation work.
Skill Codex
Debug and repair validated Harness Engineering defects with bounded scope, reproduction evidence, root-cause notes, regression protection, and validation proof. Use when a bug is already evidenced and the fix should not expand into broad improvement work.
Skill Codex
Improve existing Harness Engineering skills, references, contracts, and evals from concrete evidence such as failed evals, repeated review findings, usage traces, or documented regressions. Use when a bounded hardening pass is required; do not use for speculative redesign.
Skill Codex
Create bounded Harness Engineering execution plans from approved specs or issue slices. Use when work needs ordered implementation units, explicit scope boundaries, rollback posture, traceability, and validation gates before code changes.
Skill Codex
Create bounded, evidence-backed Harness Engineering specs from approved intent. Use when a selected issue, milestone, reframe phase, or execution slice needs acceptance criteria, traceability, risk gates, and validation boundaries before planning or implementation.
Skill Codex
Executes bounded implementation work from approved specs, plans, issues, or small fixes by editing files, running validation, preserving unrelated work, and recording rollback and handoff evidence. Use when asked to implement, execute a plan, apply changes, or build a scoped feature.
Skill Codex
Generate closure-grade HE eval and drift proof for one execution slice. Use when Linear, milestone, or source-prompt closure needs validation evidence.
Skill Codex
Convert approved HE cognition into small live-ready Linear execution tracking. Use when strategy, reframe, plan, bug, or source-prompt evidence needs scoped issue, milestone, or project routing with explicit confirmation before any live mutation.
Skill Codex
Routes old phase-heartbeat requests into HE phase work: check the approved plan, reuse or create a 10-minute continuation only with authority, run phase gates, delegate the active slice to he-work, and stop before commit or tracker closure. Use when a user says phase heartbeat, keep this PR moving, or continue phases.
Skill Codex
Runs approved Harness Engineering plans in recurring phases: check live state, confirm continuation authority, execute only the active he-work slice, verify gates, update Linear only with approval, and stop before unsafe staging or closure. Use when a plan, issue, or PR needs continued phase-by-phase execution.
Skill Codex
Analyze repo, tracker, PR, validation, session, and .harness evidence. Use when multi-stage Harness Engineering work needs safe resume routing.
Skill Codex
Create evidence-backed HE reframe migration programs. Use when structural drift, routing ambiguity, or source-prompt gaps need phased rollback-safe execution.
Skill Codex
Create or refresh evidence-bound Harness Engineering learning artifacts from verified solved problems. Use when a fix worked, a repeated failure should become durable knowledge, or .harness/solutions and Project Brain need maintenance.
Skill Codex
Compress HE cognition artifacts into evidence-backed strategy. Use when intent, review, triage, ADR, core, or source-prompt comparison evidence needs durable direction.
Skill Codex needs its repo
Install validated Codex plugins from trusted sources with quarantine validation, provenance, and rollback. Use when distribution and installation are the primary goals.
Skill Codex needs its repo
Scaffold Codex plugin packages with deterministic manifests, marketplace metadata, and traceability or evidence contracts for non-trivial adoption. Use when creating plugin roots or adopting existing skills into plugin ownership.
Skill Codex needs its repo
Analyze broad, mixed, or unclear Plugin Factory follow-up requests and select the correct plugin lane. Use when plugin intent lacks a clear lane owner.
Hook Claude Code
Runs when a session starts, executing session_start_contract.py via python3. From jscraik/Agent-Skills.
Skill Codex
Use when hardening, converting, auditing, or pre-release checking a Codex plugin package by verifying manifest paths, bundled skills, hooks, MCP/app config, validation gates, and release blockers.
Skill Codex needs its repo
Route plugin-factory requests to the right lane. Use when plugin creation, building, installation, review, or routing is broad, mixed, or under-specified.
Skill Codex
Analyzes bounded skill evidence, classifies root causes, and recommends a lifecycle lane such as keep, observe, improve through Skill Factory hardening, merge with approval, or retire with approval. Use when a skill is not working, a skill is not triggering correctly, evals or Tessl disagree, repeated failures need…
Skill Codex
Use when listing or installing Codex skills from curated sources, GitHub repo paths, private repos, or local package locations.
At most 3 mods per repository are shown here, and a mod shipped inside a plugin is left to that plugin's page — the rest are on their repository pages:
