- ip-lookupmohitagw15856/pm-claude-skillsLook up IP addresses and your own public IP with zero API keys — geolocation, ISP/ASN, and hosting flags via ip-api.com and ipify through curl. Use when asked what's my public IP, where is this IP from, whose network is this address, or is this IP a VPN/datacenter. Produces the lookup with ISP, ASN, and location fields interpreted honestly (city-level accuracy caveats included), and the rerunnable command.EngineeringNo warnings★ 1.5K↓ —
- error-scanhoangsonww/Claude-Code-Agent-MonitorScan recent Claude Code activity for errors and failure signals across all sessions using Agent Monitor data — APIError events and PreToolUse→PostToolUse gaps (tools that started but never completed) — then group failures by tool and model and rank them by frequency. Use when checking for errors or asking "what's failing right now".EngineeringNo warnings★ 1.1K↓ —
- pr-descriptionmohitagw15856/pm-claude-skillsWrite a clear pull-request description that gets reviewed fast and merged with confidence, from a git diff, branch summary, or commit list. Use when opening a PR, summarizing a change for review, documenting code changes, or asked to write a PR/merge-request description. Produces a structured PR: what changed and why, how it was tested, risk and rollout, and a focused reviewer guide — so the reviewer understands intent before reading a single diff line.WritingNo warnings★ 1.5K↓ —

- spoon-plannermohitagw15856/pm-claude-skillsBudget limited energy the way spoon theory describes it — count your realistic daily 'spoons', price what each task actually costs (including the invisible ones), protect the non-negotiables, and plan for the days you'll have far fewer. Use when someone says 'I only have so much energy', 'help me pace with my chronic illness', 'I keep crashing', or lives with ME/CFS, long COVID, fibromyalgia, POTS, MS, or any limited-capacity condition. Produces a spoon budget, a task price list, and a pacing plan that respects payback and post-exertional crashes. A self-management tool, not medical advice.PlanningNo warnings★ 1.5K↓ —
- weekly-reviewnano-muse/nanoMusenanoMuse: an open-source personal agent for every device you own. One agent with a name and a look of its own that does things, keeps working while the app is closed, remembers you, and asks before anything you cannot undo.

- ab-test-setupalirezarezvani/claude-skillsUse before planning or launching any A/B, split or multivariate test, or when asked if a result is significant.

- pm-skillsalirezarezvani/claude-skillsRouter for project-management skills: sprints, portfolio health, Jira, Confluence, stakeholder comms, plus a delivery loop.

- varg-mockupsNewhashgraph-online/awesome-codex-pluginsMock up a video before paying for it: one self-contained HTML board (storyboard board, moodboard, reference board, look test, plan page, contact sheet) with numbered frames, shot specs, prompts, approve / needs-fix / reject and a note per frame, side-by-side variants and feedback copied as Markdown; stills made on varg (Nano Banana 2.1, GPT Image 2.5) that do not look like AI slop and stay consistent (character sheets, environment master first, same lens and light); device and app UI mockups (iMessage chat, Apple Notes, iPhone fold, phone stamp carousel, terminals, code editors). Use for "mock up", "mock up a look", "mockup", "storyboard board", "moodboard", "reference board", "look test", "stills for approval", "key frames to approve", "shot board", "phone mockup", "app UI mockup", "screen mockup", or stills that look like AI slop or drift between shots. Not for final video clips (varg-video-prompting) or 3D camera blocking (threejs-animatic).TestingNo warnings★ 1.5K↓ —
- mariadb-operator-commentmariadb-operator/mariadb-operatorPost a comment (or a formal PR review) to a GitHub issue or pull request in mariadb-operator/mariadb-operator. Use whenever the user wants to publish something to GitHub for this repo — "comment on issue #123", "post this as a PR comment", "leave a note on #456", "reply on the PR" — and especially when they want the output of the mariadb-operator-pr-review skill delivered to GitHub instead of just shown in chat, e.g. "review PR #1234 and post it as a comment" or "post the review results to the PR". Always confirms the exact comment text with the user before publishing — never posts autonomously.EngineeringNo warnings★ 1K↓ —
- oma-bootstrapfirst-fluke/oh-my-agentInstall or verify the oma CLI and its runtimes (bun, uv, serena) before any oma-* skill, agent, or workflow runs an `oma` command. Use when `oma` is missing from PATH, when a skill says to run `oma ...` and the shell reports "command not found", or on the first task in a fresh Cursor or Grok Bot workspace.EngineeringNo warnings★ 1.4K↓ —
- site-architecturefcakyon/claude-codex-settingsUse when planning or restructuring what pages a site has and how they connect: hierarchy, navigation, URL patterns, breadcrumbs, and internal linking. Not for XML sitemaps, which are in seo-audit.PlanningNo warnings★ 1.2K↓ —
