One-way sync of PLAUD cloud recordings into an Obsidian vault (transcript, speaker diarization, AI notes, and highlights; no audio). Triggers on the scheduled plaud-sync job ("Load the plaud-ingestion skill and run a Plaud sync") or interactive asks like "sync plaud", "pull my Plaud recordings", "check Plaud for new…

Guard 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…

Tighten 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'…

Study 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'…

Verify 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…

Anchor 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…

Makes 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…

Fix '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…

Diagnose 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…

Set 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…

Diagnose and prevent SILENT TRUNCATION when editing large files (1000+ lines, especially CJK/multibyte markdown) via Edit/StrReplace/writefile. Use when: an edit 'succeeds' but trailing content (entire sections, main blocks) is silently dropped with no error; a full writefile rewrite produced a shorter file than…

Set up npm package publishing via GitHub Actions using Trusted Publishing (OIDC) instead of a long-lived NPMTOKEN 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…

Diagnose 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…

Diagnose 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…

When 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…
