- inithashgraph-online/awesome-codex-pluginsFirst-time Archcore setup. Wires the host (MCP config, hooks, CLAUDE.md/AGENTS.md managed block), measures the authored context the repo already holds, then composes a first-day seed — stack rule, run guide, data-model, integrations, config, entry points, public surface, a linked architecture overview, and specs for the top hotspot modules — shown in ONE preview and created on a single confirm. Modes, named as the first word: init import converts the repo's authored context — CLAUDE.md, AGENTS.md, .cursor/rules and other agent instructions, ADR and RFC folders, contributor docs, internal pages of a published docs site, recoverable git history — into native typed documents with no import marks, staged by a plan when the volume is large; init refresh adds facts that appeared since, or drills into one domain with init refresh <domain>. Use on a fresh clone, empty `.archcore/`, 'set up archcore', 'migrate our CLAUDE.md to archcore', 'import our docs and ADRs', or to wire host configs.

- concurrency-reporthoangsonww/Claude-Code-Agent-MonitorReport concurrency and parallelism for a session — how many agents ran in parallel, concurrency-lane utilization, peak parallel width, and serialization bottlenecks (sequential chains that could have run as parallel lanes) — using the Agent Monitor workflow intelligence API. Use when checking whether a multi-agent session used parallelism efficiently.EngineeringNo warnings★ 1.1K↓ —
- error-propagationhoangsonww/Claude-Code-Agent-MonitorTrace error propagation through a multi-agent session by agent depth — where failures originated, the depth at which they appeared, and how they cascaded up to parent agents — using the Agent Monitor workflow intelligence API and the session event stream. Use when a multi-agent run failed and you need to find the origin and blast radius of the failure.EngineeringNo warnings★ 1.1K↓ —

- video-skillshashgraph-online/awesome-codex-pluginsFinds the right agent skill for an AI video, image, voice or music job on varg how to (varg.ai/how-to, 2,000+ checked skills and tutorials: UGC ads, product videos, music videos, captions, talking avatars, podcasts, faceless channels, explainers, launch videos, chat-story ads, dubbing, shorts from long videos) and shows the visual options before anything is generated. Use when someone asks to make, edit, caption, voice, dub or animate a video, asks "which skill should I use", "find a skill for", "how do I make a ... video", or wants images, voiceover or music for a video, and no installed skill already covers that format; use it before writing a pipeline from scratch or searching registries. Not for running a generation itself (use varg-ai), not for formats with their own varg skill (varg-music-video, varg-character-keynote, varg-consistent-characters, varg-character-design, varg-podcast-video, varg-product-hook, varg-dropship-reel, varg-previz), and not for non-media coding tasks.MediaNo warnings★ 1.5K↓ —
- evidence-lockmohitagw15856/pm-claude-skillsWrite or rewrite a document in evidence-locked mode: no unsourced sentences — every substantive claim carries a footnote citing the exact passage in the user's provided sources, and anything unsupportable is explicitly marked. Use when asked to make a document fully sourced, add citations from my docs, ground a draft in the attached material, or produce something for audiences that will check (legal, board, regulators, enterprise buyers). Produces the document with numbered citations, a source map quoting each cited passage, and an unsupported-claims register.LegalNo warnings★ 1.5K↓ —
- hf-cloud-sagemaker-iam-preflighthuggingface/skillsEnsure a usable SageMaker execution role exists before deploying or training. Use this skill whenever about to create a SageMaker endpoint, model, training job, or any resource that requires an execution role. Use it especially when the user has not provided a role ARN explicitly, when scripts are about to call `iam:CreateRole`, or when an AccessDenied error mentions an IAM action. Never blindly call `iam:CreateRole` — always check for existing roles first. This skill prevents the most common SageMaker deployment failure: trying to create IAM resources from an SSO principal that has no IAM write permissions.OfficialDevOpsNo warnings★ 11.3K↓ —
- spend-forecasthoangsonww/Claude-Code-Agent-MonitorForecast Claude Code spend to the end of the week or month from the daily session trend on the Agent Monitor dashboard — moving average of daily spend × days remaining, added to spend-to-date. Uses /api/analytics daily_sessions, /api/pricing/cost, and /api/sessions for a per-day cost curve. Use when projecting cost or asking "where will my spend land".DataNo warnings★ 1.1K↓ —

- data-contractmohitagw15856/pm-claude-skillsDefine a data contract between a producer and consumers of a dataset/event/API. Use when asked to write a data contract, define a schema agreement, set data SLAs, or stop a producer from silently breaking downstream consumers. Produces a contract — schema with types & constraints, semantics, quality SLAs (freshness/completeness/validity), ownership, versioning & breaking-change policy, and a change process.LegalNo warnings★ 1.5K↓ —

- session-cleanuphoangsonww/Claude-Code-Agent-MonitorIdentify stale and empty Claude Code sessions in the Agent Monitor and explain the cleanup endpoint (POST /api/settings/cleanup), always showing the exact list of what WOULD be removed before anything is deleted. Cleanup permanently deletes data, so this skill previews first and requires explicit user confirmation. Use when tidying the monitoring database.DataNo warnings★ 1.1K↓ —
