- principle-separate-before-serializing-shared-statebacknotprop/pstackApply when concurrent actors might write to the same file, branch, key, or state object. Eliminate the sharing first; serialize structurally only when one shared writer is a real invariant.WritingNo warnings★ 3.5K↓ —Also in 2 other repos
- principle-separate-before-serializing-shared-statemichael-denyer/pstack-claudeApply when concurrent actors might write to the same file, branch, key, or state object. Eliminate the sharing first; serialize structurally only when one shared writer is a real invariant.WritingNo warnings★ 3.9K↓ —
- principle-migrate-callers-then-delete-legacy-apismichael-denyer/pstack-claudeApply when introducing a new internal API while old callers still exist. Migrate callers and delete the old API in the same wave instead of preserving compatibility layers.EngineeringNo warnings★ 3.9K↓ —
- principle-encode-lessons-in-structuremichael-denyer/pstack-claudeApply when you catch yourself writing the same instruction a second time, or notice a recurring correction. Encode the rule as a lint, metadata flag, runtime check, or script instead of more text.WritingNo warnings★ 3.9K↓ —
- principle-never-block-on-the-humanmichael-denyer/pstack-claudeApply when tempted to ask 'should I do X?' on reversible work.OtherNo warnings★ 3.9K↓ —
- principle-subtract-before-you-addmichael-denyer/pstack-claudeApply when sequencing an addition, refactor, or rewrite. Remove dead code, redundant validators, and stub references first, then build on the simpler base.EngineeringNo warnings★ 3.9K↓ —
- principle-foundational-thinkingmichael-denyer/pstack-claudeApply before writing logic: choosing core types and data structures, sequencing scaffold-vs-feature work, asking what concurrent actors share. Get the data structures right so downstream code becomes obvious.WritingNo warnings★ 3.9K↓ —
- principle-explain-the-numbermichael-denyer/pstack-claudeApply before you measure, and before you trust, report, or act on a number you measured: a speedup, a regression, a throughput, a latency, or an eval result. Find what limits it, and rule out that it measured something other than the work you think.OtherNo warnings★ 3.9K↓ —
- principle-migrate-callers-then-delete-legacy-apisbacknotprop/pstackApply when introducing a new internal API while old callers still exist. Migrate callers and delete the old API in the same wave instead of preserving compatibility layers.EngineeringNo warnings★ 3.5K↓ —Also in 1 other repo
- vastai-cost-tuningjeremylongshore/tons-of-skills-marketplaceReduce Vast.ai GPU, storage, and bandwidth spend without weakening workload requirements or leaving stopped resources billable.

- optimizing-promptsjeremylongshore/tons-of-skills-marketplaceExecute this skill optimizes prompts for large language models (llms) to reduce token usage, lower costs, and improve performance. it analyzes the prompt, identifies areas for simplification and redundancy removal, and rewrites the prompt to be more conci... Use when optimizing performance. Trigger with phrases like 'optimize', 'performance', or 'speed up'.OtherNo warnings★ 2.9K↓ —
- principle-experience-firstmichael-denyer/pstack-claudeApply when product, UX, or feature-scope tradeoffs come up. Choose user delight over implementation convenience; ship fewer polished features over more rough ones.DesignNo warnings★ 3.9K↓ —
- fix-merge-conflictsmichael-denyer/pstack-claudeResolve merge conflicts non-interactively, validate build and tests, and finalize conflict resolutionTestingNo warnings★ 3.9K↓ —
- narrative-enablement-kitaaron-he-zhu/aaron-marketing-skillsUse when the user asks to "make everyone tell the same story", "write our elevator pitch ladder", or "build a spokesperson Q&A and approved boilerplate pack"; derives from the narrative-registry canon, message house, and brand voice a repeatable enablement kit — an elevator ladder (10-second / 30-second / 2-minute), a spokesperson Q&A (tough questions with on-canon answers), an approved boilerplate/bio pack (25 / 50 / 100-word), and a do/don't language sheet — so sales, support, founders, and partners repeat one consistent story. Not for the launch-day runbook — use launch-day-conductor; not for finished per-channel copy — use content-writer or each discipline creative builder; not for launch-window battle cards — use sales-enablement-kit; this kit never adjudicates a claim. 叙事赋能包/电梯梯度/发言人问答/审定样板/该说不该说WritingNo warnings★ 3.1K↓ —
- ramp-rate-limitsjeremylongshore/tons-of-skills-marketplaceImplement a shared Ramp request budget with rolling-window throttling, bounded retries, pagination, and 504 recovery. Use when clients receive 429 or 504 responses or share one outbound IP. Trigger with "Ramp rate limit" or "Ramp 429".OtherNo warnings★ 2.9K↓ —
- runway-rate-limitsjeremylongshore/tons-of-skills-marketplaceAnalyze and control Runway generation concurrency, rolling daily quota, spend limits, and queued tasks without inventing an RPM cap. Use when production traffic is throttled or scaling. Trigger with: "Runway rate limits", "Runway THROTTLED tasks", "Runway concurrency".ProductivityNo warnings★ 2.9K↓ —
- miro-rate-limitsjeremylongshore/tons-of-skills-marketplaceDesign and implement repository-side Miro REST traffic controls from credit weights, supplied headers, bounded queues, and reset-aware retries. Use when preventing or recovering from Miro 429 responses. Trigger with "Miro rate limit".DesignNo warnings★ 2.9K↓ —
- anima-debug-bundlejeremylongshore/tons-of-skills-marketplaceCollect Anima SDK debug evidence for support tickets and troubleshooting. Use when filing Anima support requests, debugging code generation issues, or collecting diagnostic data for the Anima team. Trigger with: "anima debug bundle", "anima support ticket", "anima diagnostics".EngineeringNo warnings★ 2.9K↓ —
- i4h-lerobot-vizNVIDIA/skillsServe and visually inspect a converted LeRobot dataset in the browser. Use for videos and state/action timelines; do not use for raw workflow HDF5 or incomplete conversion output.BrowserNo warnings★ 3.8K↓ —
- launch-feedback-synthesizeraaron-he-zhu/aaron-marketing-skillsUse when the user asks to "triage launch feedback", "cluster reviews, comments, and board posts into themes", or "set up a you asked, we shipped loop"; produces a feedback theme digest (frequency, severity, representative quotes per theme), an open→planned→started→completed/declined status loop with duplicate-merge and notification rules, shipped-change announcement material, and a compliant social-proof harvest protocol (never incentivized store reviews). Not for repurposing or amplifying the harvested proof — use content-amplifier; not for executing testimonial outreach threads — use outreach-manager. 反馈分诊/状态环/社证收割/评测合规LegalNo warnings★ 3.1K↓ —
- chat-motion-overlaynexu-io/open-designGenerate configurable chat motion overlays from a transcript or screenshot, including plain bubble scenes, app-style chat containers, optional device frames, preset or uploaded avatars, nickname display rules, and transparent-video-ready Remotion bundles. Use when Codex needs to create reusable short-form chat clips for Douyin, demo videos, story reenactments, social-message proof scenes, or embeddable alpha overlays for Hyperframe and Remotion workflows.MediaNo warnings★ 105.7K↓ —
- principle-test-behavior-not-implementationbacknotprop/pstackApply when you write, change, or keep a test. Assert what the code's users can observe, so that the test fails when that behavior breaks and keeps passing when only the internals change.TestingNo warnings★ 3.5K↓ —Also in 1 other repo
- list-growth-designeraaron-he-zhu/aaron-marketing-skillsUse when the user asks to "grow my email list", "design a lead magnet / signup incentive", "set up double opt-in", or "plan a referral / recommendation loop"; produces a list-growth plan — acquisition channels, lead-magnet / incentive concepts, a compliant double-opt-in capture-flow spec, referral-loop mechanics, and subscriber-growth / cost-per-opt-in targets (labeled Estimated) — that feeds SEND-S (consent quality captured at acquisition) and SEND-N (lifecycle entry). Not for the signup page/popup UX itself — use landing-optimizer; not for recording the opt-in — use consent-registry; not for the confirmation-email copy — use email-creative-builder. 邮件列表增长/lead magnet/双重确认/推荐环MarketingNo warnings★ 3.1K↓ —
ctf-reverse
ljagiello/ctf-skills
From the author
Provides reverse engineering techniques for CTF challenges. Use when the main job is to understand how a compiled, obfuscated, packed, or virtualized target works before exploiting or solving it, including binaries, APKs, WASM, firmware, custom VMs, bytecode, game clients, malware-like loaders, and anti-debug or anti-analysis logic. Do not use it when the vulnerability is already understood and the remaining task is exploitation; use pwn instead. Do not use it for pure web workflows, log or disk forensics, or standalone crypto problems unless reversing the implementation is the real blocker.
