Deep briefing on one matter — current posture, what's changed, next deadline, open questions, and a risk re-assessment check, ready before a GC update or outside counsel call. Use when the user says "brief me on [matter]", "where are we on [matter]", or needs a read on a specific matter.

Before briefing, check _log.yaml for the matter slug. If the matter is not in _log.yaml, refuse and route:
> "I don't see [matter slug] in the matter log. Run /litigation-legal:matter-intake first so the conflicts check runs and the matter workspace is set up. I won't build a briefing on a matter that hasn't been intaken — the conflicts check is the gate."
Slug (required). If ambiguous or missing, ask the user to pick from a list of active matters.

# [Matter Name] — Briefing as of [today]
**Status:** [status / stage]
**Risk:** [rating] ([severity] × [likelihood])
**Materiality:** [category]
**Outside counsel:** [firm — lead]
**Last updated:** [date] [flag ⚠️ STALE if >30d]
**Conflicts:** [status — flag ⚠️ if `pending` or `not-run`]

## One-paragraph summary
[Current posture. What are we doing and why. Name the pivot fact if one is captured.]
## What's changed recently
[Last 3-5 entries from history.md, most recent first. If history is thin, say so.]
## What's next
- **Immediate deadline:** [next_deadline + what it is]
- **Upcoming milestones:** [anything dated in matter.md or recent history]
- **Decisions pending:** [open questions flagged in matter.md]
## Exposure
[Range + any change since intake. If reserved, current reserve + whether recalibration is overdue.]
## Internal owners
[Who's looped in; whether anyone should be looped in and isn't]
## Risk re-assessment check
*A prompt, not an answer.*
- Does `risk: [rating]` still feel right, or has the case moved?
- Does `materiality: [category]` still match? (New facts might push toward reserve or disclosure.)
- Any new stakeholder the matter needs (e.g., CISO becomes relevant after a discovery development)?
## Open questions
[From matter.md and anything unresolved in history]
## For the conversation
[If user specified a purpose — "brief me before the call with outside counsel" — tailor the final section: questions to ask, decisions to get, updates to extract. If no purpose given, omit this section.]
If last_updated > 30 days ago: flag at the top AND suggest running /litigation-legal:matter-update [slug] after the meeting to capture whatever's discussed.
This is not marketing. Say what's known; flag what's not. If a matter has thin history and was just opened, the briefing is short — and that's correct. Don't pad.

/matter-update with field changes — this skill reads, doesn't write.Integration with protocols.io API for managing scientific protocols. This skill should be used when working with protocols.io to search, create, update, or publish protocols; manage protocol steps and materials; handle discussions and comments; organize workspaces; upload and manage files; or integrate protocols.io functionality into workflows. Applicable for protocol discovery, collaborative protocol development, experiment tracking, lab protocol management, and scientific documentation.
Analyzes job descriptions and generates tailored resumes that highlight relevant experience, skills, and achievements to maximize interview chances
Generate Excalidraw diagrams from natural language descriptions. Use when asked to "create a diagram", "make a flowchart", "visualize a process", "draw a system architecture", "create a mind map", or "generate an Excalidraw file". Supports flowcharts, relationship diagrams, mind maps, and system architecture diagrams. Outputs .excalidraw JSON files that can be opened directly in Excalidraw.
Build and distribute Expo development clients locally or via TestFlight
Use when you have a written implementation plan to execute in a separate session with review checkpoints
Data structure for annotated matrices in single-cell analysis. Use when working with .h5ad files or integrating with the scverse ecosystem. This is the data format skill—for analysis workflows use scanpy; for probabilistic models use scvi-tools; for population-scale queries use cellxgene-census.
Benchling R&D platform integration. Access registry (DNA, proteins), inventory, ELN entries, workflows via API, build Benchling Apps, query Data Warehouse, for lab data management automation.
Comprehensive molecular biology toolkit. Use for sequence manipulation, file parsing (FASTA/GenBank/PDB), phylogenetics, and programmatic NCBI/PubMed access (Bio.Entrez). Best for batch processing, custom bioinformatics pipelines, BLAST automation. For quick lookups use gget; for multi-service integration use bioservices.
