- migrationhashgraph-online/awesome-codex-pluginsBring an existing codebase into Dryforge, once. Reads the code, asks what code cannot show — business rules, security policy, what is intentional — and writes the project docs at the entry points agents already read. Use when the user invokes the `migration` skill on an existing project. Requires git.SecurityNo warnings★ 1.5K↓ —Also in 3 other repos
- list-connectionsmicrosoft/power-platform-skillsLists Power Platform connections in the current environment. Use when you need a connection ID before adding a connector to a code app.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↓ —
- sharpenNewhashgraph-online/awesome-codex-pluginsRewrite a draft prompt so it asks for an expert-depth version of the same task (expert moves, raw sources, named methods, an outside check) without widening scope. Returns the rewritten prompt and does not do the task. Use for "/sharpen <prompt>" or "make this prompt better before I send it".ProductivityNo warnings★ 1.5K↓ —
- 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↓ —
- taste-skillhuytieu/COG-second-brainAnti-slop frontend skill for landing pages, portfolios, and redesigns. The agent reads the brief, infers the right design direction, and ships interfaces that do not look templated. Real design systems when applicable, audit-first on redesigns, strict pre-flight check.DesignNo warnings★ 1.3K↓ —
- generate-prdhuytieu/COG-second-brainGenerate product requirements documents with optional publishing to Confluence or other wiki platformsPlanningNo warnings★ 1.3K↓ —
- auto-researchhuytieu/COG-second-brainDeep strategic research engine — decomposes questions into parallel research threads, spawns multiple agents, and synthesizes into actionable strategic analysisScienceNo warnings★ 1.3K↓ —
- wordpress-elementorjezweb/claude-skillsEdit Elementor pages and manage templates on WordPress sites via browser automation (for visual / structural changes) or WP-CLI (for safe text replacements). Use whenever the user wants to edit an Elementor page, update text in Elementor widgets, apply or manage Elementor templates, or make content changes to pages built with the Elementor page builder.BrowserNo warnings★ 1.1K↓ —
- image-processingjezweb/claude-skillsProcess images for web development — resize, crop, trim whitespace, convert formats (PNG/WebP/JPG), optimise file size, generate thumbnails, create OG card images. Uses Pillow (Python) — no ImageMagick needed. Trigger with 'resize image', 'convert to webp', 'trim logo', 'optimise images', 'make thumbnail', 'create OG image', 'crop whitespace', 'process image', or 'image too large'.MediaNo warnings★ 1.1K↓ —
- meetingsalirezarezvani/claude-skillsUse when someone wants to decide whether a meeting is worth calling, price a meeting in dollars, build a timeboxed agenda with desired outcomes, or turn messy meeting notes into owned action items — or says "should this be a meeting", "/cs-meeting-prep", or "/cs-meeting-actions". Runs a cost gate (ASYNC / NOT-READY / MEET), builds a decision-first agenda, and extracts an owner + due-date checklist that flags every orphan.ProductivityNo warnings★ 29.3K↓ —
- release-videohuytieu/COG-second-brainTurn a product release (the list of shipped items plus real screen recordings) into a motion recap video and one explained demo per feature, with sound effects tied to on-screen motion and a composed music bed. Use when asked for a release video, a changelog video, a feature recap reel, or demo clips for release notes and docs.MediaNo warnings★ 1.3K↓ —
- update-knowledge-basehuytieu/COG-second-brainMaintain and update product knowledge base from releases, features, and project changes with optional wiki syncOtherNo warnings★ 1.3K↓ —Also in 1 other repo
- memory-hygienehuytieu/COG-second-brainPeriodic trust sweep of persistent memory and durable knowledge notes - re-verifies environment-dependent claims against the live environment, stamps last_verified + confidence, and proposes archiving drifted entriesProductivityNo warnings★ 1.3K↓ —
- optimization-suggesthoangsonww/Claude-Code-Agent-MonitorSuggest concrete optimizations for Claude Code usage based on historical session data. Covers cost reduction, speed improvement, error prevention, and workflow efficiency. Use for data-driven optimization planning.PlanningNo warnings★ 1.1K↓ —
- responsiveness-checkjezweb/claude-skillsTest website responsiveness across viewport widths using browser automation. Resizes a single session through breakpoints, screenshots each width, and detects layout transitions (column changes, nav switches, overflow). Produces comparison reports showing exactly where layouts break. Trigger with 'responsiveness check', 'check responsive', 'breakpoint test', 'viewport test', 'responsive sweep', 'check breakpoints', or 'test at mobile'.TestingNo warnings★ 1.1K↓ —
- voice-baselinehuytieu/COG-second-brainMeasure your own writing corpus for the words and sentence shapes you over-use, so an agent writing in your voice stops amplifying your tics into a style. Produces a counted baseline file and checks any new draft against it. Use when an agent's drafts start sounding like a caricature of you, before publishing anything written in your voice, or every ten new pieces to re-measure.WritingNo warnings★ 1.3K↓ —
- weekly-checkinhuytieu/COG-second-brainCross-domain pattern analysis and strategic reflection for weekly reviewEngineeringNo warnings★ 1.3K↓ —
- comprehensive-analysishuytieu/COG-second-brainDeep-dive 7-day analysis across all data sources for weekly reviews, board prep, and strategic planningPlanningNo warnings★ 1.3K↓ —Also in 1 other repo
- quality-manager-qmralirezarezvani/claude-skillsUse for QMR duties under ISO 13485 5.5.2: management review, quality policy and objectives, quality KPIs and cost of quality.

- product-ui-tastehuytieu/COG-second-brainAnti-slop skill for PRODUCT UI - dashboards, data tables, forms, multi-step flows, settings, list/detail, app shells. The agent reads the surface, budgets the frame first, and ships dense interfaces that are correct at every edge case (overflow, long labels, empty/error/loading states, i18n expansion, keyboard/a11y). House-system-first; maps to Carbon/Polaris/Atlaskit/Fluent/Primer/Material3/Radix-shadcn/Ant. The counterpart to taste-skill, which owns landing/portfolio/marketing.DesignNo warnings★ 1.3K↓ —
- manage-flowsmicrosoft/power-platform-skillsManage flow lifecycle - publish, test, batch operations, inventory reports. Use when the user asks to publish, test, batch manage, or get an inventory of flows. Inventories page large environment lists and state which environments were covered.TestingNo warnings★ 1.1K↓ —
- google-apps-scriptjezweb/claude-skillsBuild Google Apps Script automation for Sheets and Workspace. Custom menus, triggers (onEdit / time-driven / form submit), dialogs, sidebars, email batches, PDF export, external API.

ctf-misc
ljagiello/ctf-skills
From the author
Provides miscellaneous CTF challenge techniques for problems that do not cleanly fit the main categories. Use for encoding puzzles, pyjails, bash jails, RF/SDR, DNS oddities, unicode tricks, esoteric languages, QR or audio puzzles, constraint solving, game theory, unusual sandbox escapes, and hybrid logic puzzles. Prefer a more specific skill first when the challenge is mainly web, pwn, reverse, forensics, malware, OSINT, or crypto. Treat this as the fallback skill for genuine cross-category or edge-case challenges, not the default starting point.
