Review fallow's LSP server behavior, diagnostics, code actions, code lens, and protocol-facing UX. Use when changes touch crates/lsp or LSP-visible behavior.

Update a stale session branch by rebasing onto the latest origin. Use when the upstream has moved significantly and the session needs to catch up, resolving conflicts by preserving upstream changes and adapting session work to fit.

Analyze Copilot session history for standup reports, usage tips, session search, and session reindexing. Use when the user asks for a standup, daily summary, usage tips, workflow recommendations, wants to search or find past sessions by keyword/file/PR, wants to reindex their session store, or asks about deleting session data.

Open or advance a Positron PR that bumps the Ark submodule to a given Ark PR (its head while open, its merge commit once merged) or to latest Ark main, with Positron e2e test tags. Use when the user runs /bump-ark with a PR number or "main" and optional @:tags.

Preview the test-coverage verdict PETE will post, locally, before a PR exists. PETE is Positron's CI "PR Test Checker" -- it grades whether a PR adds adequate tests for its source changes and posts a verdict comment. This skill replays the same rubric and file classification against your working tree (committed + uncommitted + untracked changes vs the merge-base with the default branch) and renders the verdict in-session -- it posts nothing and needs no network or gh. Use when asked to "run PETE" / "run PETE locally", to preview or check test coverage before opening or pushing a PR, to see whether the current branch has adequate tests, or to anticipate what PETE / the PR Test Checker will say.

Use in Claude Code when a user asks to read, analyze, summarize, or extract from a heavyweight file such as PDF, DOCX, PPTX, XLSX, CSV, or TSV. Convert the file into markdown or CSV first with the bundled script, generate a lightweight index, and only spend model tokens on the compressed artifact.

Structures a technical paper's full logical skeleton using a thinking-template table (research background, limitations, key idea or goal, challenges, methodology modules, contributions), positions the paper as Technique or New Problem/Setting, and runs a four-point self-consistency check. Use when the user is brainstorming a paper, discussing progress with an advisor, or planning the paper before drafting. Also use for 'paper skeleton', 'paper logic chain', 'thinking template', 'paper-structure planning'.

Install context files from registry. Use when user runs /install-context, says "install context", "setup context", or when context is missing and the user needs to get started.

Manage regulatory compliance for international phone numbers. Covers what bundles are, which countries require them, how to create End-Users and Supporting Documents, evaluate and submit bundles, fix evaluation failures, update bundles when regulations change, and ISV multi-account patterns. Use this skill when provisioning numbers outside the US.

Screen existing protein binders with Boltz. Use when ranking a supplied protein, peptide, antibody, nanobody, or binder library against a target. Not for designing new proteins or screening small molecules.

This skill installs mixpanel_headless, pandas, numpy, matplotlib, seaborn, networkx, anytree, scipy (and pyarrow on Python 3.11+), then verifies Mixpanel credentials. It should be invoked when setting up a new environment for Mixpanel data analysis, when dependencies are missing, or when configuring service account or OAuth credentials for the first time.

Submit compact Ensembl REST API requests for lookup, overlap, cross-reference, and variation endpoints. Use when a user wants concise Ensembl summaries

Capture a website and create a HyperFrames video from it. Use when: (1) a user provides a URL and wants a video, (2) someone says "capture this site", "turn this into a video", "make a promo from my site", (3) the user wants a social ad, product tour, or any video based on an existing website, (4) the user shares a link and asks for any kind of video content. Even if the user just pastes a URL — this is the skill to use.

Submit compact ClinicalTrials.gov API v2 requests for study search, metadata, enums, search areas, and field statistics. Use when a user wants concise ClinicalTrials.gov summaries

Set up and manage Twilio authentication credentials: Auth Tokens, API keys (Standard, Main, Restricted), Access Tokens for client-side SDKs, and credential rotation. Use this skill as a prerequisite foundation before making any Twilio API calls.

Build multi-party calls using Twilio Conference. Covers warm transfer, cold transfer, coaching (whisper), hold vs mute, participant modes, and supervisor barge. Use this skill for any contact center, support line, or scenario requiring transfers, holds, or multi-party calls.

Use when testing, debugging, or making targeted improvements to rendered frontend apps through the Build Web Apps or web dev plugin: local dev servers, UI regressions, interaction bugs, console errors, responsive layout, and visual QA. Check whether the Browser plugin is available and use it first when it is; otherwise use regular Playwright with the recorded reason.

Fetch compact TPMI PheWAS summaries for single variants by accepting rsID, GRCh37, or GRCh38 input and resolving to the required GRCh38 query. Use when a user wants concise TPMI association results for one variant

Diagnostic and advisory skill for email deliverability problems. Use when a developer asks why emails are going to spam, not reaching the inbox, getting blocked, bouncing, or how to improve sender reputation — with or without a specified platform. Covers SendGrid-specific tooling: SPF, DKIM, DMARC, BIMI, IP warmup, list hygiene, bounce/spam rate thresholds, and Engagement Quality Score (SEQ). Do NOT use for Twilio Email (comms.twilio.com / Account SID + Auth Token) — use twilio-email-deliverability-advisor instead. Do NOT use for general email sending questions — use twilio-sendgrid-email-send (SendGrid) or twilio-email-deliverability-advisor instead.

Use when the caller has Twilio credentials (Account SID + Auth Token or API Key SID + Secret) and needs to send email via comms.twilio.com/v1/Emails. This is Twilio-native email — NOT SendGrid. Do NOT use if the caller has a SendGrid API key (SG.-prefix) — use twilio-sendgrid-email-send instead. Covers single sends, batch sends up to 10,000 recipients, Liquid personalization, operation tracking, and error handling.
