Agents Md ImproverAProposes updates to AGENTS.md so repo-local coding-agent instructions stay accurate, non-contradictory, and consolidated. Use when the user corrects the agent (e.g. do not do X, always do Y, from now on, remember this), asks to edit or sync AGENTS.md, CLAUDE.md, .claude/CLAUDE.md, or GEMINI.md, wants one canonical instruction file or to deduplicate agent docs, or flags conflicting or outdated repository agent rules.ai-agentsVotes: 0GitHub stars: 39
Atomic CommitsABreak unstaged or mixed changes into small, atomic, logical git commits with Conventional Commit messages. Use when the user asks to commit, stage, or split changes — e.g. 'help me commit', 'commit my changes', 'break these into logical commits', 'what should I commit first', 'stage my changes', 'commit atomically', or 'make atomic commits'. Uses git diff, git add -p, and Conventional Commits (feat:/fix:/refactor:/chore:/docs:/test:/style:/perf:/build:/ci).developmentgorefactoringVotes: 0GitHub stars: 39
Coherent WritingAImprove coherence in drafts by diagnosing broken flow, rewriting transitions, aligning paragraph purpose, and preserving author voice. Use when a user says things like 'make this coherent', 'tighten the flow', 'this feels choppy', 'can you smooth transitions', or asks to revise prose in Markdown, notes, essays, blog posts, emails, or docs so ideas connect cleanly from sentence to sentence and section to section.documentationgoVotes: 0GitHub stars: 39

Epistemic ResourcefulnessDBreaks the cycle of repeated failed attempts by redirecting to the authoritative source of truth before trying again. Trigger when: the same command or query has failed 2+ times; output is garbled/binary; guessed field names, endpoints, or flags keep erroring; scanning yields no signal; you are about to say 'I don't have access to X' (a CLI may exist: gog = Gmail; check which/brew and script logs first); you are about to label a step 'manual' or 'human-only' (the API likely supports it — intr...databasespythonrustVotes: 0GitHub stars: 39
Gh Activity SummaryAGenerate a plain-language activity report of your GitHub work for a date range or a single day, including commits, pull requests, reviews, issues, comments, and a chronological event timeline.

Gh CliAUse GitHub CLI (gh) for common operations like creating PRs, viewing GitHub Actions logs, managing issues, GitHub Projects boards (gh project field/item automation), reviewing PRs, and more. When merging PRs via gh, use rebase merge only (--rebase) — standing user rule (Eric, 2026-08-26: "in general i want to do rebases only, never any type of merge"): never merge commits, never squash-merge, unless Eric explicitly requests otherwise for a specific PR.devopsgoshellVotes: 0GitHub stars: 39
Gh Pr Code ReviewAPR code review workflow: pull diff, two-pass findings, draft and prioritize comments, then optionally post via gh api.documentationgobashVotes: 0GitHub stars: 39
Html PresentationsACreate single-file HTML slide presentations with vanilla JS/CSS. Themed (terminal.css, catppuccin, nord), keyboard-navigable, with inline SVG diagrams and animations. Use when the user asks for an HTML presentation, slide deck, or single-file slides without a framework.developmentjavascriptpythonVotes: 0GitHub stars: 39
MempalaceAUse the MemPalace CLI to persist, search, and manage AI memory across sessions. Triggers whenever the user asks to remember, recall, save, store, or retrieve information that should persist across conversations — including past decisions, preferences, facts about people or projects, conversation history, and any verbatim content the user wants preserved. Also triggers when the user mentions "palace", "wings", "rooms", "drawers", "knowledge graph", "AAAK", or when they want to search through h...ai-agentspythonbashVotes: 0GitHub stars: 39

Covers single-hypothesis scoping, fast iteration loops, targeted logging, JOURNAL.md protocol, data-backed diagnostic plots, and scientific report writing.datapythongoVotes: 0GitHub stars: 39
Pdf Form FillerAFill PDF forms: flat PDFs with NO fillable fields and fillable AcroForm PDFs with real fields (school enrollment packets, medical intakes, waivers, government paperwork) and reuse a prior year's filled PDF as the source of answers. Requires a vision-language-model coding agent (renders pages to images and looks at them); there is no non-VLM fallback. Use when: the user asks to fill out / complete / fill in a PDF form, especially recurring yearly forms (enrollment, renewal, intake) where a pre...developmentpythonrustVotes: 0GitHub stars: 39
Publish To Google DocsAQuickly publish markdown notes to styled Google Docs using pandoc and a Word template. Use when creating Google Docs from markdown, applying branding to documents, or pushing content to Drive for sharing.toolsgobashVotes: 0GitHub stars: 39
Scientific EdaADefensive exploratory data analysis for scientific data (CSV, FASTA, etc.).

Stacked Pr DecompositionABreak long-lived pull request branches into a mergeable stack of small PRs with clear dependency order and story flow. Use when a branch has grown too large, when the user asks to split a PR into stacked PRs, when a stacked PR shows no CI checks because workflows filter on main (fix: gh stack init), when a freshly gh-stack-registered stack shows no workflow runs (fix: push one real commit to fire synchronize), when the user asks about GitHub's native stacked-PR feature or gh stack commands, w...documentationgoshellVotes: 0GitHub stars: 39
Voss AdvisorAAdvanced negotiation and communication advisor grounded in Chris Voss's tactical empathy methodology (Never Split the Difference). Use for any interpersonal situation involving influence, persuasion, or difficult dynamics: preparing for negotiations (salary, vendor, client, partner), drafting tactful responses, handling pushback or objections, tough workplace conversations, performance reviews, landlords and contractors, personal disagreements, negotiation role-play, or asks like "how should ...businessrustgoVotes: 0GitHub stars: 39

Audit Before RewriteAGuard against silent feature loss when REWRITING, RESTYLING, or REFACTORING an existing artifact via a wholesale file rewrite (HTML demo, marimo notebook, code file, design doc, ADR, SKILL.md). Use when: a restyling/refactoring subagent is about to rewrite a file that had features added in prior turns; you are converting an inline snippet to a standalone file or vice versa; a notebook is being re-saved/restructured; a design doc's decision is being revised to a previously-rejected alternative...content-marketinggorailsVotes: 0GitHub stars: 39
Blog Explainer Prose DedupATighten long-form explainer/pedagogical blog prose by auditing for facts and concepts stated 2+ times across sections and condensing each to a single mention with forward-references. Use when the user says 'less repetitive', 'more pedagogically coherent', 'too repetitive', 'this restates what was already said', 'tighten the prose', or flags a concept explained multiple times (intro re-explains, body re-derives, later section re-states). ALSO governs the INVERSE coverage problem: a takeaway/su...developmentrustgoVotes: 0GitHub stars: 39
Codebase Study Parallel ReportersAStudy an unfamiliar codebase (or audit a feature across repos) by dispatching PARALLEL READ-ONLY reporter subagents in a SINGLE tool block, NOT by reading files one-at-a-time in the main thread. Use when the user says 'study how X works', 'audit the codebase', 'understand the architecture', 'investigate the repo', 'read these files and report', hands you a file/line-range/grep list to examine, or asks to compare how two repos implement the same feature. Each reporter gets: a focused concern, ...researchgoapiVotes: 0GitHub stars: 39
Data Visualization MasterAMaster skill for creating, critiquing, and improving data visualizations — charts, plots, and figures for analysis, publications, blogs, slides, and dashboards. Synthesizes the Nature Methods "Points of View" series (Bang Wong, Martin Krzywinski, and coauthors) with the evidence-tagged rules of the evident-charts skill (Cleveland & McGill graphical perception, Tufte, and modern visualization research). Load for any chart/figure/plot request in matplotlib, seaborn, plotly, ggplot2, Altair/Vega...researchpythongoVotes: 0GitHub stars: 39
Docker Offline VerificationAVerify a containerized Docker app runs with ZERO network access (offline verification of demos, teaching sites, deployed containers). Use when: you must prove a containerized app serves every route without internet; a docker run combining --network none with -p fails to publish or reach ports; a --network none container's ports time out and it LOOKS like an app failure. ROOT CAUSE: port publishing (-p) requires an attached network — with --network none there is no network to publish from, so ...devopsdockerVotes: 0GitHub stars: 39
Dom Anchored Svg ConnectorsAAnchor connector lines/arrows/edges between rendered DOM elements (gantt dependency arrows, org-chart parent-child lines, flowchart edges, annotation leader lines) on MEASURED element rects — NEVER compute connector coordinates de novo (percentage math, hardcoded px widths, or a second parallel layout math). Use when drawing connectors in vanilla JS/HTML, or when the user reports connectors 'misaligned', 'all over the place', or 'floating detached from the boxes'; trigger: any second, indepen...devopsnodeVotes: 0GitHub stars: 39
Evident ChartsAMakes explanatory charts whose point is evident, using evidence-tagged dataviz rules. Use whenever you create, revise, restyle, or review a chart, plot, graph, or figure meant to show a reader something: matplotlib, seaborn, pandas .plot, ggplot2, Plotly, Altair/Vega-Lite, D3, or any PNG/SVG chart for a blog, report, paper, slide, newsletter, or social post. Starts from sound analysis of the data, picks the chart type from the takeaway and data shape, and runs deterministic checks (overlaps, ...researchpythonVotes: 0GitHub stars: 39
Git Rebase Noninteractive EditorAFix 'git rebase --continue' (and 'git rebase -i') blocking or timing out in a non-interactive shell (bash tools, CI, scripts, scheduled jobs) because git opens an interactive editor (nano/vi) with no TTY that waits forever for stdin. Use when: rebase --continue hangs or the shell tool times out with no commit produced (especially after 'git add'-ing resolved conflicts); you see 'GNU nano' or a vi screen in rebase output; you are about to re-run --continue hoping it works; or you are doing ANY...toolsshellbashVotes: 0GitHub stars: 39
Github Auto Merge SetupBDiagnose and fix 'gh pr merge --auto' failures and set up CI-green auto-merge for GitHub repos/workflows. Use when: 'gh pr merge --auto' or a workflow merge step fails with an enablePullRequestAutoMerge error; auto-merge silently not working; enabling auto-merge for scheduled dependency-update workflows (dependabot etc.); adding a ruleset/branch protection with required status checks and choosing safe required checks; choosing merge flags (--rebase/--squash); a release workflow's push to main...testingpythongoVotes: 0GitHub stars: 39
Jupyterlab Collab Mcp SetupASet up and verify the jupyterlab-collab-mcp MCP server so an agent can read/edit/execute Jupyter notebooks with real-time collaboration. Use when the user says 'connect to the jupyter MCP server', 'check the jupyterlab collab mcp', 'jlabx extensions aren't working', 'verify the MCP server is installed', the agent has no jupyter MCP tools despite expecting them, or notebook edits via MCP fail or return connection errors.

Large File Edit Truncation GuardrailADiagnose and prevent SILENT TRUNCATION when editing large files (1000+ lines, especially CJK/multibyte markdown) via Edit/StrReplace/write_file. Use when: an edit 'succeeds' but trailing content (entire sections, __main__ blocks) is silently dropped with no error; a full write_file rewrite produced a shorter file than expected; an Edit FAILED and you are considering a write_file fallback (do NOT — the #1 truncation trigger); the dedicated Grep tool finds nothing for content ripgrep finds in a...content-marketingpythongoVotes: 0GitHub stars: 39
Marimo Notebook PatternsAPitfalls for writing/editing marimo notebook .py files, and for mutating a RUNNING notebook via marimo-pair code_mode (ctx.edit_cell/create_cell/move_cell). Covers: import patterns (never alias marimo as mo), cell params (mo received as a parameter), App() init, unique-variable rules incl. the loop-variable cell-collision (namespace loop vars per cell), cross-cell symbol removal, ran-error traceback triage, import-cell return values, underscore-prefix privacy, button/toast/callout/slider/prog...code-qualitypythonrustVotes: 0GitHub stars: 39

Npm Trusted Publishing Oidc SetupASet up npm package publishing via GitHub Actions using Trusted Publishing (OIDC) instead of a long-lived NPM_TOKEN secret. Use when: the user asks to publish an npm package via CI/CD, set up a publish workflow, or automate npm releases; npmjs.com shows the 'security risks with this option... use Trusted Publishing instead' warning; or you are about to recommend an npm automation token + GitHub secret. Key gotchas: Node 24 required (npm 11.5.1+); the publish step must have NO NODE_AUTH_TOKEN e...devopsrustgoVotes: 0GitHub stars: 39
Opencode Bash Background Process SurvivalADiagnose and fix backgrounded processes (dev servers, nohup'd jobs) that get KILLED when the bash tool's command terminates, completes, or times out — even when started with nohup & disown. Use when: a backgrounded server died by the next turn or when the launching command timed out; the dev server started last turn returns connection refused / curl 000; 'shell tool terminated command after exceeding timeout' appears and the PID is gone; you need a process to survive across multiple bash-tool...toolspythongoVotes: 0GitHub stars: 39
Opencode Mcp Server SetupAAdd or configure an MCP server in opencode's config (~/.config/opencode/opencode.json or project .opencode/) — both server types: LOCAL/stdio {"type": "local", "command": ["npx", "pkg"], "enabled": true} and REMOTE/HTTP {"type": "remote", "url": "...", "enabled": true}. Use when the user says 'add the X MCP server', 'install/configure MCP', 'connect to <service> MCP', an MCP server appears in docs but isn't wired into opencode, tools from a known MCP server are missing in a session, or a serv...securitypythongoVotes: 0GitHub stars: 39
Opencode Ollama Provider SetupAAdd an Ollama-hosted model (local laptop or a remote box like the GB10) as a usable model/provider in opencode, and verify it end-to-end. Use when the user asks to 'add <model> from ollama to opencode', 'use ollama model X in opencode', 'wire up a local model in opencode', when adding an Ollama model to opencode.json, smoke-testing an Ollama OpenAI-compatible endpoint with curl, diagnosing EMPTY content from a thinking/reasoning model, or wondering why the new provider does not appear without...ai-agentspythongoVotes: 0GitHub stars: 39
Opencode Plugin AuthoringFBuild opencode (opencode-ai) plugins — the lifecycle pattern, the event surface for notifications/hooks, and local from-source install. Use when creating an opencode plugin, writing a notification/hook plugin, wiring session.idle/session.error events, deciding how to install a local plugin (symlink vs plugin array), reading the @opencode-ai/plugin types, using the Bun $ shell helper inside a plugin, checking npm/GitHub name availability for an opencode plugin package, or configuring plugin se...testingtypescriptrustVotes: 0GitHub stars: 39
Python Importtime OptimizationADiagnose and fix slow Python package import times. Use when: 'import pkg' or 'from pkg import X' takes seconds (CI import-time benchmarks slipping, CLI startup lag, marimo/Jupyter import latency); you suspect eager heavy imports in __init__.py; a module-level 'import lib' exists ONLY to set a side-effect flag and you need the lazy-set pattern; making imports lazy and verifying nothing still imports at load time; or dating an import-time regression from CI per-PR benchmark comments. Covers pyt...testingpythonrustVotes: 0GitHub stars: 39
Webfetch Empty Use Agent BrowserAWhen webfetch returns garbled binary from a .pdf/.docx/.xlsx URL (PDF magic bytes, mojibake), do NOT pivot to agent-browser: download with curl and extract via pdftotext or pypdf/pdfplumber (see the Binary files section). Otherwise, when webfetch yields an empty body, a TOO-LARGE response, a near-empty JS-rendered shell, or fails on a dynamic page, SWITCH to agent-browser instead of retrying — 'too large' is the same signal as 'empty'.
