geo-database
by jaechang-hits
"Query NCBI Gene Expression Omnibus (GEO) for gene expression datasets and sample metadata via GEOparse Python library and E-utilities. Search datasets by keyword/organism/platform, download GSE series matrices, parse GPL platform annotations, extract GSM sample metadata, and load expression matrices into pandas. For single-cell data use cellxgene-census; for programmatic multi-DB access use gget-genomic-databases."
harmony-batch-correction
by jaechang-hits
"Batch correction for single-cell RNA-seq (and other omics) with Harmony. Removes technical batch effects from PCA embeddings while preserving biological variation. Use after PCA, before UMAP/neighbors. Fast and scalable to millions of cells. Python (harmonypy, scanpy integration) and R (Seurat) APIs."
reins
by pegasi-ai
Use this skill whenever security, policies, governance, guardrails, compliance, or safety are relevant — including blocked commands, audit trails, dangerous operations, deletions, file modifications, shell commands, MCP access, API calls, network requests, credentials, or any action that could be irreversible or destructive. Reins installs deterministic PreToolUse/PostToolUse hooks and connects to Watchtower (app.pegasi.ai) for centralized governance.
h3-pg
by postgis
PostgreSQL bindings for H3 hexagonal grid system. Use when working with H3 cells in Postgres, including spatial indexing, geometry/geography integration, and raster analysis.
agent-recall
by Goldentrii
Persistent compounding memory for AI agents. 5 default MCP tools: session_start, session_end, remember, recall, check. Full surface (18 tools) available with --full flag. Two-verb model: inhale (session_start) and exhale (session_end). Correction-first memory with decision trail tracking, watch_for warnings, palace rooms with salience scoring, cross-project insight matching, same-day journal merging, ambient recall hooks. Local markdown only. Zero cloud, zero telemetry, Obsidian-compatible. Optional Supabase backend: when configured via ar setup supabase, recall() uses pgvector cosine similarity on OpenAI/Voyage embeddings instead of keyword search — same API, semantic understanding. Gracefully degrades to local search if not configured.
authoring-analysis
by adobe
Analyze content sequences and determine authoring approach (default content vs blocks). Validates block selection and section styling for import/migration to AEM Edge Delivery Services.
api-rate-limiting
by aj-geddes
Implement API rate limiting strategies using token bucket, sliding window, and fixed window algorithms. Use when protecting APIs from abuse, managing traffic, or implementing tiered rate limits.
project-init
by BlackBeltTechnology
'Scaffold an unconfigured directory into a configured pi project. Interactive, profile-driven: previews the planned writes, then writes AGENTS.md, .pi/settings.json and prompt files — optionally also a knowledge base, an openspec/ scaffold, and user-global ~/.pi/agent/settings.json. Use on a bare directory, or when the dashboard''s "Initialize" button spawns this session.'
node-inspect-debugger
by BlackBeltTechnology
'See runtime state a console.log cannot reach — set real breakpoints, step, and dump the scope chain of a paused Node/TypeScript process. Use on "set a breakpoint", "inspect runtime state", "console.log isn''t enough", "step through this", "what''s in this closure at runtime", "attach a debugger". Not a logging or observability-setup workflow.'
canvas-webapp
by BlackBeltTechnology
Render a React/Vite (or any bundled) web app on the pi-dashboard canvas, which loads loopback URLs in a sandboxed opaque-origin iframe. Use when a canvas(target:{kind:"url" "server"}) target shows up blank white, an empty surface, or a /live/<id> 500 ECONNREFUSED. Covers why Vite dev servers and non-CORS static servers fail there, and the static-build + CORS-server recipe that works.
rebuild-package-diagrams
by BlackBeltTechnology
Render a reverse-spec rebuild package as traced, script-checked visuals — a Mermaid ER diagram of model.md entities, capability use cases as BPMN processes, and one browsable HTML catalog. Use on "ER diagram from the entities", "draw the data model", "use cases as BPMN", "browsable HTML of the rebuild package", "ER diagram az entitásokból", "üzleti folyamat BPMN-ben".
reverse-spec-for-rebuild
by BlackBeltTechnology
'Characterize existing code into a rebuild package a team can reimplement from without the source: behavior specs, domain model, BR-NNN rules (explicit/implicit), quirks, gaps, entry-point completeness, each claim cited file:line with confidence. Use on "reverse-engineer this for a rebuild", "extract the business rules", "reimplement X without the original code", "characterize code for a rewrite".'
dox-describe
by BlackBeltTechnology
Fill the empty Purpose cells of a directory AGENTS.md tree with one-line LLM summaries (one subagent per file, plan-then-confirm, cap 50 rows/run). Use for a path-only kb dox init tree, or when asked to "describe the tree", "fill AGENTS.md purposes", or "populate the kb corpus".
youtube-srt
by BlackBeltTechnology
Download YouTube subtitles (SRT + timestamped TXT) for a channel, playlist or video via yt-dlp, no media download; optionally mine them into a categorized catalog (e.g. AI models by function, open weights, local runnability, hardware tier). Use on "download the srt of this video", "transcripts of channel X for the last N months", "catalog the models AI Search talked about", "update docs/models".
nano-banana-imagegen
by BlackBeltTechnology
Generate and edit images using Google Gemini image models via the nano-banana CLI. Use when the user asks to create, generate, make, or edit images with AI. Supports text-to-image, image editing, style transfer, and multi-image composition. Trigger on requests like "create an image", "generate a picture", "make me a logo", "edit this photo", "add X to this image".
doctor
by BlackBeltTechnology
'Diagnose why pi-flows, the Anthropic-messages bridge, model resolution, a pi install, a peer, a plugin/bridge, or a build/reload is broken in the pi-agent-dashboard. Derives every fact live (works with the server down). Use on "flow won''t show", "bridge waiting_peers", "pi version mismatch", "which pi is this using", "diagnose the dashboard", "doctor".'
doubt-driven-review
by BlackBeltTechnology
'In-flight adversarial check on a non-trivial decision BEFORE it stands — distinct from post-hoc review of a finished diff. Use on "stress-test this decision", "are we sure about this", "verify before commit", "poke holes in this", when working in unfamiliar code, or before an irreversible step (migration, prod deploy, public API). Runs earlier than code-review, while course-correction is cheap.'
review-code
by BlackBeltTechnology
'Review a code change well — engine-agnostic critical review discipline for an inline dev loop. Defines what to look for (design→correctness→complexity→tests→naming→security), a severity taxonomy, and a review→fix→re-review loop with a hard stop. Use on "review this code", "review my diff", "is this change good", "critique this implementation", "review before commit". Not a ship-gate.'
veo-generator
by BlackBeltTechnology
'Render a scripted video project into mp4 clips with the Google Veo 3.1 API. Reads a project''s shot package (shots/*.md), one clip per camera cut, reusing each shot''s prompt and sketch — world anchor only with --with-reference, seed unless --no-seed. Use on "render the Veo video for <project>", "generate the videos from the shot scripts", "make the clips with Veo".'
veo-showreel-production-kit
by BlackBeltTechnology
"Turn a video timeline + voiceover into a reproducible, sliceable Veo 3.1 prompt package with a consistency anchor and AI storyboard sketches."
beat-sync-video
by BlackBeltTechnology
"Lock a picture edit to a music edit: scene boundaries on downbeats and drops, plus irregular camera-punch hits from bass re-entries and vocal hooks (<stem>_hits.json, schema music-hits/1) with a HyperFrames adapter recipe. Use on \"sync the video to the beat\", \"add camera punches on the drops\", \"cut on the music\", \"make the edit hit the drop\"."
music-analysis
by BlackBeltTechnology
"Analyse a local audio file into a versioned music map (<stem>_map.json, schema music-map/1): tempo from the downbeat grid, 1-based bars, key, band levels, classed sections, drop candidates, optional stems and style tags. Use on \"analyse this track\", \"what BPM / where is the drop\", \"map the song for editing\", or before cutting music or syncing video to it."
music-edit-to-length
by BlackBeltTechnology
"Cut a music track to a target length on its downbeat grid with scored, click-free joins, writing <out>.wav and a video-time beat grid (<out>_edit.json, schema music-edit/1). Use on \"cut the music to 90 seconds\", \"fit the track to the video\", \"shorten this song on the beat\", \"re-cut the music edit\"."
footage-redaction
by BlackBeltTechnology
"Bake redaction into screen-recording or camera footage from a JSON spec: fixed crops, time-windowed logo removal, and blurs that switch on only while a detected UI element is on screen, then verify on contact sheets. Use on \"redact this recording\", \"blur the IP / e-mail / URL\", \"remove the watermark\", \"cut clips with redaction baked in\"."
