- second-brain-ingestundefined-ui/second-brain-osTurn raw source material in a second-brain vault into linked wiki pages: read the source, split it into concepts and entities, write or update pages, connect them to existing pages, and record the run in the log. Use this skill whenever the user drops a file into raw/, pastes an article, transcript or PDF and asks to add it to the vault, says "ingest this", "add this to my second brain", "process raw", or asks to catch up on unprocessed sources, even if they do not name the ingest command. Do NOT use for answering questions from an existing vault, for linting or repairing pages, or for editing notes the user wrote by hand.DocumentsNo warnings★ 1.3K↓ —
- second-brain-writeundefined-ui/second-brain-osDraft from the vault: outline from concept pages, keep citations to the user's own sources, and surface where their material disagrees. Use this skill when the user wants to write an article, post, essay or newsletter based on what they have collected, or asks what they could write about a topic. Do NOT use for research reports, for writing with no grounding in the vault, or for editing text the user wrote themselves unless asked.WritingNo warnings★ 1.3K↓ —
- social-media-kithuytieu/COG-second-brainAttach native media (teaser video, GIF, card images) to every social post, with per-platform upload stepsMarketingNo warnings★ 1.3K↓ —
- second-brain-lintundefined-ui/second-brain-osAudit a second-brain vault for structural problems and repair them: broken wikilinks, orphan pages, empty stubs, frontmatter that violates the schema, near-duplicate pages, and stale index entries. Use this skill whenever the user asks to lint, clean, audit or check the health of their vault, says pages feel messy or links are broken, after a large bulk import, or when a scheduled maintenance run fires. Do NOT use for ingesting new sources, for answering questions from the vault, or for rewriting page content that is structurally fine but reads badly.OtherNo warnings★ 1.3K↓ —
- brief-from-pilemohitagw15856/pm-claude-skillsTurn a folder of accumulated documents into one decision-ready brief — the skim-map pass over the pile, the extraction against the brief's actual questions, the conflict reconciliation when documents disagree, and the provenance trail back to sources. Use when asked read all this and tell me what matters, synthesize this folder for the new lead, turn these 20 docs into a brief, or what does all this material actually say. Produces the pile map, the question-driven extraction, the reconciled brief with per-claim sources, and the didn't-read honesty ledger.OtherNo warnings★ 1.5K↓ —
- audit-performancedzhng/skillsAudit and prioritize performance work through bounded-work and forward-progress checks. Use when asked to find performance issues, investigate freezes/500s/OOMs, review retries or polling for no-progress loops, rank a performance backlog, or implement the next simple performance fixes.FinanceNo warnings★ 1.4K↓ —
- deep-researchjezweb/claude-skillsDeep research and discovery before building something new. Explores local projects for reusable code, researches competitors, reads forums and reviews, analyses plugin ecosystems, investigates technical options, and produces a comprehensive research brief. Three depths: focused (30 min), wide (1-2 hours), deep (3-6 hours). Triggers: 'research this', 'discovery', 'explore the space', 'what should I build', 'competitive analysis', 'before I start building', 'research before coding'. Not for cited fact-checking research reports (a separate harness does those); this is pre-build product discovery.ScienceNo warnings★ 1.1K↓ —
- parcel-trackingjezweb/claude-skillsTrack parcels and check delivery status for Australian and international couriers. Searches Gmail for dispatch/shipping emails and provides tracking links for all major Australian couriers including AusPost, StarTrack, Aramex, CouriersPlease, Sendle, Toll, Team Global Express, DHL, FedEx, TNT, Hunter Express, Border Express, Direct Freight Express, and UPS. Triggers: 'where is my parcel', 'track my order', 'has my package arrived', 'tracking status', 'check tracking', 'where is my delivery'.OtherNo warnings★ 1.1K↓ —
- atc-supplementarybrycewang-stanford/Awesome-Journal-SkillsUse when deciding what belongs in the ATC (ACM SIGOPS Annual Technical Conference, formerly USENIX ATC) two-page extended abstract, the 12-page paper body, the optional appendix, and the artifact — splitting content by review round and decision-criticality so nothing that decides acceptance lives where a reviewer is not required to read.ScienceNo warnings★ 1.4K↓ —
- bank-fee-refundmohitagw15856/pm-claude-skillsGet a bank fee waived or refunded — overdraft, late, maintenance, ATM, or foreign-transaction — with the ask written and the leverage that works. Use when asked to get a bank fee refunded, waive my overdraft fee, the bank charged me a fee, or how to get charges reversed. Produces a read on which fees are commonly reversible, the script to request a refund (in person, chat, or call), the loyalty/first-time/error leverage to use, and how to prevent the fee recurring — plus when to escalate or switch banks.WritingNo warnings★ 1.5K↓ —
- claude-apihashgraph-online/awesome-codex-pluginsAnthropic Claude API patterns for Python and TypeScript. Covers Messages API, streaming, tool use, vision, extended thinking, batches, prompt caching, and Claude Agent SDK. Use when building applications with the Claude API or Anthropic SDKs.EngineeringNo warnings★ 1.5K↓ —
- planning-with-filesOthmanAdi/planning-with-filesPersistent file-based planning for multi-step AI-agent work. Keeps task_plan.md, findings.md, and progress.md on disk; lifecycle hooks inject selected project planning context. Automatic recovery reads project planning files only. Explicit session-catchup.py --metadata reads same-project local agent session records and emits aggregate counts only; --replay may emit bounded nonce-framed excerpts. Optional gated mode can request continuation only when the host supports it and never runs commands declared in Markdown. The skill has no network upload path. Use for research or work needing 5+ tool calls.PlanningNo warnings★ 27.9K↓ —Also in 1 other repo
- orchestratehashgraph-online/awesome-codex-pluginsCoordinate several workers: what idle agents do next, which finished work gets checked first, how to recover a dead one. Use when: managing multiple agents.OtherNo warnings★ 1.5K↓ —Also in 2 other repos
- simplifyfcakyon/claude-codex-settingsThis skill should be used when the user asks to "simplify", "clean up the diff", "run simplify", "simplify the changes", "review changed code for cleanup", explicitly invokes "/simplify", or asks to "commit without simplify", "skip simplify for this commit", or "commit this but skip simplify". Reviews changed code across reuse, simplification, efficiency, and altitude, or grants an explicit one-commit bypass. Not for correctness bugs.EngineeringNo warnings★ 1.2K↓ —

- runway-plannermohitagw15856/pm-claude-skillsTurn burn and cash into a clear runway picture and a raise decision — months left, default-alive vs default-dead, and what to cut or change. Use when asked to calculate runway, model burn rate, decide when to raise, figure out if the company is default-alive, or plan a scenario with hiring/cuts. Produces the runway math, a default-alive verdict, and dated trigger points for raising or acting. Not financial advice.PlanningNo warnings★ 1.5K↓ —
- second-brain-graphundefined-ui/second-brain-osAnalyse the vault's link graph and report on its shape: orphan rate, average degree, components, hubs, bridges and clusters, with what each number means for retrieval. Use this skill when the user asks about the health or structure of their graph, wants metrics, asks which pages are most connected or most isolated, or asks whether the vault is fragmented. Do NOT use for fixing what it finds, which is second-brain-lint, or for answering a content question.OtherNo warnings★ 1.3K↓ —
- anti-entropy-governanceGanyuanRan/AegisUse when touching retiring old logic, collapsing duplicate owners, removing fallbacks, or schema/persistence/source-of-truth boundaries; identify opportunities automatically; destructive execution requires explicit confirmation.OtherNo warnings★ 1.4K↓ —
