- analyze-performance-diagnosegooseworks-ai/goose-skillsStep of the analyze-performance playbook: flags tracking breaks with fixes and explains each big metric move with evidence, confidence and ruled-out causes. Run analyze-performance instead; not for direct use.OtherNo warnings★ 1.3K↓ —
- itcs-workflowbrycewang-stanford/Awesome-Journal-SkillsUse to plan an ITCS campaign end to end on its single annual cycle — backward from the early-September deadline through the no-rebuttal review, the November notification, the LIPIcs camera-ready, and the January conference with its Graduating Bits session.ProductivityNo warnings★ 1.4K↓ —
- vis-workflowbrycewang-stanford/Awesome-Journal-SkillsUse when planning an IEEE VIS project timeline from area fit through the abstract and full-paper deadlines, the two-phase review, the conditional-accept second round, the IEEE TVCG camera-ready, the Graphics Replicability Stamp, and presentation, with backward-planning offsets for a visualization paper and honest handling of the annual cycle and the second-round revision window.ProductivityNo warnings★ 1.4K↓ —
- pnas-figuresbrycewang-stanford/Awesome-Journal-SkillsUse to finalize PNAS display items — column-width sizing (~9 / 11.4 / 18 cm), minimum font sizes, show-the-data with n and defined error bars, scale bars, colorblind-safe palettes, legend structure, image integrity, and color-mode notes. Enforces figure rigor before submission.MediaNo warnings★ 1.4K↓ —
- research-market-market-passgooseworks-ai/goose-skillsStep of the research-market playbook: the worker brief for researching the market itself, including category, size, changes, pricing norms and demand. Run research-market instead; not for direct use.ScienceNo warnings★ 1.3K↓ —
- lancet-fitbrycewang-stanford/Awesome-Journal-SkillsUse when scoping a project and before any writing, to stress-test whether a study clears The Lancet's bar — clinically or public-health important, globally relevant, and likely to change practice or policy, often with an equity lens. Decides The Lancet vs a Lancet family title vs another general medical journal.TestingNo warnings★ 1.4K↓ —
- cell-rebuttalbrycewang-stanford/Awesome-Journal-SkillsUse after Cell reviews arrive to triage the decision, prioritize the (often substantial) new experiments by impact × feasibility, and draft a point-by-point response that is respectful, evidence-led, and closes the "completeness" gaps reviewers demand. Do not run before the experiments and revision are actually done.OtherNo warnings★ 1.4K↓ —
- reviewhashgraph-online/awesome-codex-pluginsThe pre-merge review of a branch in a project that records its specs, decisions, and rules in .archcore/. Run this first for 'review my branch', 'review the changes before merge', or 'review before merge': it checks the changed code against the project's recorded canon and the changed documents against the code, and reports which side is wrong — spec-wrong or code-wrong; on the default branch it reviews the unpushed and uncommitted work. A bug-hunting code review complements this review and does not replace it. Also use for 'documentation gaps', 'check if docs match code', 'close out the feature', 'ship the feature and close it out', or after a staleness warning. Takes an optional path, tag, topic, or ref in free text; no first word is a mode — say 'are docs out of date', 'audit the knowledge base', 'close out the feature', or 'capture this pattern' in plain words. Not for creating docs — use /archcore:document; not for planning — use /archcore:plan; not for a single-file edit with no branch review.EngineeringNo warnings★ 1.5K↓ —Also in 1 other repo
- report-issuemicrosoft/power-platform-skillsUse when the user wants a Process Intelligence bug-report draft or support summary for a failed operation.ProductivityNo warnings★ 1.1K↓ —
- shiphashgraph-online/awesome-codex-pluginsRelease-gate sequence: validate → review → push → tag. Wraps kernel:git mechanics with the pre-ship safety chain. Triggers: ship, release, push to main, ready to merge, deploy.DevOpsNo warnings★ 1.5K↓ —
- azure-aimicrosoft/azure-skillsUse for Azure AI: Search, Speech, OpenAI, Document Intelligence. Helps with search, vector/hybrid search, speech-to-text, text-to-speech, transcription, OCR. WHEN: AI Search, query search, vector search, hybrid search, semantic search, speech-to-text, text-to-speech, transcribe, OCR, convert text to speech.DevOpsNo warnings★ 1.6K↓ —Also in 1 other repo
- ad-creative-testingNewhashgraph-online/awesome-codex-pluginsTurn one winning ad into a creative testing plan for TikTok and Meta. Decodes why an ad won (hook, argument, buyer, format), plans concepts that Meta's Andromeda and TikTok treat as genuinely different (buyer × angle × format × first frame, not caption swaps), sets how many creatives to launch, the budget per test and when to judge, writes file and ad names that make results readable, reads hook rate, hold rate, CTR and CPA to find which part failed, and says when to kill, iterate or scale. Use when someone asks how many ads to test, how to make ad variants, why their variants all perform the same, whether an ad is fatigued, when to kill an ad, or how to scale a winner. NOT for producing the videos (use ecommerce-video-ads, ecommerce-video-edit or product-video-hooks) or for media-buying account setup.TestingNo warnings★ 1.5K↓ —
- cell-databrycewang-stanford/Awesome-Journal-SkillsUse to build Cell's data and code deposition plan and the Data and Code Availability statement that lives inside STAR Methods Resource Availability — approved repositories, accessions/DOIs at submission, and Cell's three-bullet availability format with Mendeley Data as Elsevier's default.PlanningNo warnings★ 1.4K↓ —
- chi-workflowbrycewang-stanford/Awesome-Journal-SkillsUse when planning an ACM CHI submission cycle end to end — the single September deadline, two-round review with a five-week revise-and-resubmit window, December decisions, the TAPS and publication-ready chain, and the May conference — with owners and risk buffers for each stage.ProductivityNo warnings★ 1.4K↓ —
- runtypehashgraph-online/awesome-codex-pluginsScope a Runtype project or set up platform access; route implementation to the relevant Runtype skill.OtherNo warnings★ 1.5K↓ —
- ap-execharness-resolverSpielewoy/autoprompt-skillReport the compatibility redirect to `ap-worker`; this retired role cannot perform new work.OtherNo warnings★ 1.2K↓ —
- sci-databrycewang-stanford/Awesome-Journal-SkillsUse to build Science's data, code, and materials availability — mandatory deposition in approved repositories, accession numbers, a compliant data-availability statement, and materials/reagent sharing.ScienceNo warnings★ 1.4K↓ —
- keyword-researchkostja94/marketing-skillsWhen the user wants to research keywords, find target keywords, or analyze search intent. Also use when the user mentions "keyword research," "keyword tool," "target keywords," "search volume," "search intent," "keyword difficulty," "topical map," "keyword clustering," "People Also Ask," "Google autocomplete," "autocomplete keywords," or "alphabet method." For clusters, use content-strategy.ScienceNo warnings★ 1.1K↓ —
- write-specdzhng/skillsBreak large features into independently verifiable, human-reviewable slices under a feature directory in specs/. Use for risky or multi-step feature work that needs upfront questioning, API seams, browser-playable checkpoints, HTML visualizations, screenshot gates, staged implementation plans, recursive fog-of-war reslicing, or proactive research into reference implementations/best practices before slicing. Pairs with your project's verification harness and screenshot gates (the browser checkpoints), [refactor-clean](../refactor-clean/SKILL.md) (review the materialized spec so the plan describes one-owner architecture, not the feature bolted on), [screenshot-critique](../../visual/screenshot-critique/SKILL.md) and [compare-screenshots](../../visual/compare-screenshots/SKILL.md) (the visual gates), and a code-review pass (audit each slice before it lands).WritingNo warnings★ 1.4K↓ —
- email-lifecycle-send-checkgooseworks-ai/goose-skillsChecks a drafted email flow or broadcast before it is loaded: flow logic and exits, overlaps, offer depth and codes, stock, claims, consent and legal footer, SMS rules, rendering, voice and AI-copy tells, and the goal metric. Returns a pass / fixed / open-question table. Use alone when you already have the finished draft and the brand's product and policy facts; otherwise run email-lifecycle.ProductivityNo warnings★ 1.3K↓ —
- work-with-creators-creator-vettinggooseworks-ai/goose-skillsVets creators you have already named from their public pages. Covers the median views of their last 12 to 20 posts (sponsored and organic apart), a read of their comments, how often they post, audience fit with how sure it is, about 12 months of brand-safety checks, rival partnerships and rules for regulated categories. Gives a verdict with dated numbers for each one. Use alone when you already have the creator handles and the brand's goal; otherwise run work-with-creators.LegalNo warnings★ 1.3K↓ —
- cluelesshashgraph-online/awesome-codex-pluginsUse when the user explicitly cannot review the output in the current domain, says they do not understand it or will copy-paste without checking, or requests clueless mode. Examples: "I know nothing about this", "не разбираюсь", "сделай за меня". Brevity, "make it nice", and delegation alone do not establish a knowledge gap.EngineeringNo warnings★ 1.5K↓ —
- code-quality-revieweralibaba/skill-upReviews code and provides detailed quality assessmentEngineeringNo warnings★ 1.4K↓ —
- email-lifecycle-offer-mathgooseworks-ai/goose-skillsPrices one discount, free-shipping threshold or referral reward against contribution margin: cost per order, share of margin used, break-even lift, code leakage risks, and one recommended offer in two plain sentences. Use alone when you already have the offer, average order value and margin per product; otherwise run email-lifecycle.ProductivityNo warnings★ 1.3K↓ —
