- email-lifecyclegooseworks-ai/goose-skillsLifecycle email, SMS and push: audits the list and deliverability, then writes the flows this kind of business needs first, loadable as-is in your own tool, plus segments, cadence and this week's broadcasts. Never sends anything. Use when: set up my welcome and abandoned-cart emails; trial onboarding or waitlist launch emails; win back lapsed customers; plan this week's emails and texts; push notifications for my app; why are my emails going to spam; plan our Black Friday email and SMS sends; a send went wrong. Not for cold outreach to prospects — use write-outreach; not the editorial newsletter issue — use make-content; not the whole cross-channel Black Friday plan — use plan-campaign.ProductivityNo warnings★ 1.3K↓ —
- honest-reviewgooseworks-ai/goose-skillsShared step of the marketing playbooks (make-static-ads, run-organic-social): how to review generated images and video honestly. Covers what was seen by eye versus read automatically, findings framed as things for the human to confirm, remakes only after a yes to the price, and at most two tries per item. Loaded by those playbooks; not for direct use.EngineeringNo warnings★ 1.3K↓ —

Records pass/fail/needs-human in verification.md. Used as the final check in the static ad remix flow before shipping.MediaNo warnings★ 1.3K↓ —

- gohashgraph-online/awesome-codex-pluginsCarry out the intent approved in `ready`, as meant, and prove it with checks that actually ran. Comes back to you if the work would change what you approved, keeps the project docs in step, and never merges on its own. Use when the user invokes the `go` skill after `ready`. Requires git.EngineeringNo warnings★ 1.5K↓ —Also in 3 other repos
- work-with-creators-brief-writergooseworks-ai/goose-skillsWrites a one-page brief for one creator you have already picked: hook ideas in their format, at most three approved must-say lines, never-says, the disclosure for their platform, deliverables, timeline, the usage-rights ask and two examples. Adds a short first-message draft (gift and paid versions) for you to send. Use alone when you already have the creator, their best fitting post and the goal; otherwise run work-with-creators.WritingNo warnings★ 1.3K↓ —
- x-apihashgraph-online/awesome-codex-pluginsX/Twitter API integration for posting tweets, threads, reading timelines, search, and analytics.

- doca-upgradeNVIDIA/skillsChanging DOCA versions safely: upgrading or downgrading the host DOCA packages, refreshing the BlueField BFB, bumping the NGC DOCA container tag, or rolling back, with the discipline detect -> report -> ASK -> only then a guided upgrade. Trigger on "is there a newer DOCA", "I want the newest DOCA features, can I just apt upgrade in place", "should I move to the next release", "the upgrade stopped midway and dpkg is in a broken state", "my component is being deprecated, what now", or "roll me back", even without the word upgrade. Detect what is installed, find the newer release, report the gap, then STOP and ask for explicit confirmation; never upgrade automatically. Do not use it for a runtime error on an unchanged install (doca-debug). Version detection alone belongs to doca-version, first-time install to doca-setup, any hardware / firmware / reboot step to doca-hardware-safety, and public-docs or sunset routing to doca-public-knowledge-map.EngineeringNo warnings★ 3.8K↓ —
- skill-authoringTencentCloudBase/CloudBase-AI-ToolkitDesign, improve, and evaluate reusable agent skills with high-quality SKILL.md files, precise trigger descriptions, progressive disclosure, and testable behavior. This skill should be used when users ask to create a new skill, rewrite or review an existing skill, audit a skill collection such as `config/source/skills` for redundancy or overlap, improve skill trigger quality, organize skill references, or evaluate whether a skill should trigger and behave correctly.DesignNo warnings★ 1.2K↓ —
- write-outreachgooseworks-ai/goose-skillsCold outreach a person sends to business buyers: email and LinkedIn sequences, a first line per prospect, reply and objection answers, and a read of replies. Use when the marketer says "write a cold email sequence", "what do I send to this list", "write LinkedIn messages for these leads", "how do I reply to this prospect" or "handle this objection", "reply to this demo request", "win back or reconnect with accounts that churned or went quiet", or "why is nobody replying to my outreach". Drafts only; the marketer sends from their own tool. Not for finding the people — use research-audience; not for emails to subscribers or users, or consumer win-back — use email-lifecycle.WritingNo warnings★ 1.3K↓ —
- oma-brainstormNewfirst-fluke/oh-my-agentExplore goals, constraints, and alternative approaches before choosing a design. Use when the user requests ideation or design exploration.PlanningNo warnings★ 1.4K↓ —
- unity-agent-workflowshashgraph-online/awesome-codex-pluginsUse for AI-assisted Unity work that needs live repo discovery, project-derived routing, runtime-owner proof, runtime-visible output hard stops, runtime numeric proof for repeated visible-output failures, state-step guards, multi-agent scope ownership, modular C#/asmdef safety, UI/scene/visual asset gates, data-first content changes, validation, cleanup proof, or durable workflow rules. Best when agents must prove the actual folder/module/scene/prefab/runtime owner before editing, especially runtime UI, generated assets, code graphs, tutorial/state flows, guided selection/action flows, overlay/dim source-bound mistakes, coordinate conversions, focus/highlight/marker/HUD alignment, predictive lead aiming, ballistic trajectories, spatial IoU verification, or repeated "fix still not visible" failures.DesignNo warnings★ 1.5K↓ —
- oma-imagefirst-fluke/oh-my-agentMulti-vendor AI image generation with authentication-aware parallel dispatch. Routes to Codex (gpt-image-2 via ChatGPT OAuth) and Pollinations (flux/zimage, free with signup). Gemini provider is present but disabled by default (requires billing).

Do not use for generic image generation.BrowserNo warnings★ 1.5K↓ —
- learn-my-brandgooseworks-ai/goose-skillsLearn my brand once and stop asking me every time. Use when someone says learn my brand, set up my brand, here's our brand book, remember how we talk, what can we claim, can we say this, approve our claims, sign off our voice, our price or product changed, the client approved the claims, pick up where we left off, or check our claims are still current. Reads what GooseWorks already found about the brand, asks only the gaps as drafts to confirm, audits every claim (including ones research marked approved) and gets the ones that matter signed off with proof, scope and review date, turns the voice into rules the owner confirms, checks logo, colours and fonts, and saves it all as it goes so every other job loads it instead of asking. Ends with an unknowns list and a read-back. Not for who our customers are and what they say (use research-audience) or writing positioning from scratch (not covered yet).ScienceNo warnings★ 1.3K↓ —
- calculator-designrampstackco/claude-skillsDesigning interactive calculators (ROI calculators, pricing estimators, savings projections, mortgage calculators, custom assessments) that deliver real decision-support value while serving as lead magnets and qualified-traffic generators. Honest about vanity-calculator (no real value), lead-trap (hides the answer behind email), and transparent-decision-tool (gives the result and earns the email through tiered value) patterns. Triggers on calculator, ROI calculator, pricing estimator, savings calculator, custom calculator, interactive tool, decision tool, financial calculator. Also triggers when an audience needs a calculation-driven lead magnet, when a vanity calculator is producing leads but no qualified ones, or when a calculator is being scoped for the first time.DesignNo warnings★ 1K↓ —

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.

- kling-4-promptingNewhashgraph-online/awesome-codex-pluginsHow to prompt Kling 4 (Kling 4.0, kling_v4) for cinematic AI video that does not look like AI slop: let a strong image model compose every shot, then give Kling 4 two to four key frames and a short director's prompt. Covers reference-to-video inputs (@Image, @Element, @Video, @Voice), multi-shot prompts with seconds, 30-second takes, dialogue in quotes, "no slow motion", lens and film-look lines, prompts that fail and their rewrites, elements that need two photos, the failure fixes (slow motion by default, six fingers, AI-smooth framing, face drift in close-ups) and the exact varg call with the reference route pinned. Use when someone asks how to prompt Kling 4, why Kling 4 looks worse than Seedance 2.5, how to use Kling 4 reference-to-video, elements, multi_prompt or keyframes, or wants a Kling 4 prompt written. For a whole short film use kling-4-keyframe-film; for a 30-second action montage use kling-4-action-montage.MediaNo warnings★ 1.5K↓ —

closed-loop
huytieu/COG-second-brain
PlanningUpdated Oct 23, 2026
From the author
Run one task through the V-model verification loop: CP-2 plan → CP-3 build → CP-3v component verify → CP-4 integration verify (full lane) → CP-5 acceptance. The worker never grades its own homework; evidence rows trace back to AC-n. Opt-in: invoke with /closed-loop or by asking for the closed loop, proper verification, or an evidence trail. Ordinary work does not run this.
