- 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; agent instructions read selected project planning context when invoked. 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. This adapter registers no lifecycle or Stop hook, never requests continuation, 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★ 27.8K↓ —

- 01-graders-and-pipelineagentscope-ai/OpenJudgeBuild custom LLM evaluation pipelines using the OpenJudge framework. Covers selecting and configuring graders (LLM-based, function-based, agentic), running batch evaluations with GradingRunner, combining scores with aggregators, applying evaluation strategies (voting, average), auto-generating graders from data, and analyzing results (pairwise win rates, statistics, validation metrics). Use when the user wants to evaluate LLM outputs, compare multiple models, design scoring criteria, or build an automated evaluation system.DesignNo warnings★ 1K↓ —
- huggingface-community-evalshuggingface/skillsRun evaluations for Hugging Face Hub models using inspect-ai and lighteval on local hardware. Use for backend selection, local GPU evals, and choosing between vLLM / Transformers / accelerate. Not for HF Jobs orchestration, model-card PRs, .eval_results publication, or community-evals automation.OfficialOtherNo warnings★ 11.3K↓ —
- huggingface-vision-trainerhuggingface/skillsTrains and fine-tunes vision models for object detection (D-FINE, RT-DETR v2, DETR, YOLOS), image classification (timm models — MobileNetV3, MobileViT, ResNet, ViT/DINOv3 — plus any Transformers classifier), and SAM/SAM2 segmentation using Hugging Face Transformers on Hugging Face Jobs cloud GPUs. Covers COCO-format dataset preparation, Albumentations augmentation, mAP/mAR evaluation, accuracy metrics, SAM segmentation with bbox/point prompts, DiceCE loss, hardware selection, cost estimation, Trackio monitoring, and Hub persistence. Use when users mention training object detection, image classification, SAM, SAM2, segmentation, image matting, DETR, D-FINE, RT-DETR, ViT, timm, MobileNet, ResNet, bounding box models, or fine-tuning vision models on Hugging Face Jobs.OfficialMediaNo warnings★ 11.3K↓ —
- 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★ 1.2K↓ —
- hf-cloud-python-env-setuphuggingface/skillsSet up an isolated Python environment for SageMaker / AWS work, with the right Python version and current boto3. Use this skill whenever Python code will be executed for a SageMaker deployment, training job, or any AWS automation — including when about to run `pip install`, when about to invoke `boto3`, when creating or activating a virtualenv, or when the user asks to "set up the environment". Never use system Python and never `pip install` into it. Always isolate. This skill prevents the most common failure modes: wrong Python version, dependency conflicts, and stale SDKs.OfficialEngineeringNo warnings★ 11.3K↓ —
- research-market-edge-casesgooseworks-ai/goose-skillsStep of the research-market playbook: rules for run edge cases such as no browser, stalled workers, earlier reports and late reads. Run research-market instead; not for direct use.ScienceNo warnings★ 1.3K↓ —
- tddNewhashgraph-online/awesome-codex-pluginsWhen a bug can be caught by an inexpensive local test, write that narrow failing test before the fix, check that it fails because of the bug, then fix the code and watch the test pass. Use on /tdd, "write a failing test first", "add a regression test", or when a bug has an obvious inexpensive test location.TestingNo warnings★ 1.5K↓ —
- planhashgraph-online/awesome-codex-pluginsPlan a game or app with the person before building it — sensible defaults from their request, with an interview only when requested that ends in the game's Game Codex, games/<id>/CODEX.md, drawn as a page in the game's own palette, fonts and art that anyone can read and steer (a Claude artifact where the app has artifacts, else a page in their browser, and a private page on the studio's site), kept true as decisions change, with the build's progress on it. Use for step 4 of a new studio, or when someone says "let's plan my game", "what should my game be", "make a design doc, a game bible or a codex", "show me the plan", or before a big change to a game.PlanningNo warnings★ 1.5K↓ —
- atc-experimentsbrycewang-stanford/Awesome-Journal-SkillsUse when designing or auditing the evaluation of an ATC (ACM SIGOPS Annual Technical Conference, formerly USENIX ATC) systems paper — matching evidence to the claim with real testbeds, fair baselines, end-to-end plus microbenchmark results, tail-latency and variance reporting, workload realism, and honest cost accounting.ScienceNo warnings★ 1.4K↓ —
- sci-rebuttalbrycewang-stanford/Awesome-Journal-SkillsUse after Science reviews arrive to triage the decision, prioritize experiments, and draft a point-by-point response that is respectful, evidence-led, and honest about limits. Do not run before the main text is actually revised.ScienceNo warnings★ 1.4K↓ —
- five-whyshashgraph-online/awesome-codex-pluginsRoot cause analysis using the Five Whys technique. Use when a bug persists despite surface fixes, a failure recurs, or a process keeps breaking. Ensures the fix targets the root, not the symptom.OtherNo warnings★ 1.5K↓ —
- content-repurposingScrapeCreators/social-media-research-skillsUse when the user wants to turn public social videos, transcripts, posts, or creator research into reusable content assets such as LinkedIn posts, X threads, short-form scripts, newsletters, blog outlines, carousels, or content calendars.ScienceNo warnings★ 5.3K↓ —
- teachNewhashgraph-online/awesome-codex-pluginsTeach someone a diff, subsystem or idea in the code by combining how and why into a plain, paced conversation with diagrams that build up one piece at a time. Use for "teach me", "help me understand", "walk me through this change". Never edits code.WritingNo warnings★ 1.5K↓ —
- archivehashgraph-online/awesome-codex-pluginsUse at ship time to merge the spec into the living documentation, delete the staging spec and plan, and ask how to finish.PlanningNo warnings★ 1.5K↓ —
