Corporate Counsel Plugin

In-house corporate counsel workflows across four practice areas: M&A deals, board and corporate secretary, public company governance, and entity management. Activate only the modules that apply to your role. The cold-start interview is modular — it asks targeted questions per active area and writes only the relevant sections to your practice profile.

Every output is a draft for attorney review — cited, flagged, and gated — not a legal conclusion. The plugin does the work: reads the documents, applies your playbook, finds the issues, drafts the memo. A lawyer reviews, verifies, and decides. Citations are tagged by source so you know which ones came from a research tool and which ones need checking. Privilege markers are applied conservatively so nothing waives by accident. Consequential actions — filing, sending, executing — are gated behind explicit confirmation.

Who this is for

Role	Active modules
In-house M&A counsel	M&A
Corporate / assistant secretary	Board & Secretary
GC at a public company	M&A + Public Company + Board & Secretary
GC at a private company	M&A + Board & Secretary + Entity Management
Legal ops / solo GC	Whichever apply — mix and match

First run

/corporate-legal:cold-start-interview

Walks through module selection, then a short targeted interview for each active area. Writes a modular ~/.claude/plugins/config/claude-for-legal/corporate-legal/CLAUDE.md with only the relevant sections. Your configuration is stored at that path and survives plugin updates.

Per-deal setup (M&A module only):

/corporate-legal:cold-start-interview --new-deal

Commands

Command	Does
/corporate-legal:cold-start-interview	Modular cold-start, or --new-deal / --module [m&a | board | public | entities]
/corporate-legal:diligence-issue-extraction [folder]	Read VDR docs, extract issues in house format
/corporate-legal:tabular-review	Tabular review — one row per document, one column per data point, every cell cited to source, Excel output
/corporate-legal:material-contract-schedule	Material contracts disclosure schedule from diligence findings
/corporate-legal:closing-checklist	Closing checklist — what's blocking, critical path
/corporate-legal:written-consent	Unanimous written consent — precedent-matched draft + signatory tracker
/corporate-legal:entity-compliance	Entity compliance tracker — init, report, update, audit, export
/corporate-legal:integration-management	Post-closing integration workplan, consents tracker, contract assignment, status reports
/corporate-legal:matter-workspace	Manage matter workspaces (multi-client private practice only) — new, list, switch, close, none

Prerequisites

Several features reference Slack, Google Drive, SharePoint, Box, Intralinks, or Datasite integrations. These require MCP servers configured in your environment — they are not bundled with the plugin. Without them, the plugin falls back to file output (drafts written locally rather than posted to a channel, tracker files written to disk rather than read from a connected repository).

Configure MCP servers in .mcp.json at the repo or user level. Skills and agents will detect what's available at runtime and adjust behavior.

Skills

Skill	Module	Purpose
cold-start-interview	All	Modular interview — activates only relevant sections
diligence-issue-extraction	M&A	VDR docs → issues in house format, by category
tabular-review	M&A	Review a document set against a typed column schema; cited cells; .xlsx / .csv / markdown output; feeds material-contract-schedule
deal-team-summary	M&A	Tiered briefs: exec / deal lead / working team
material-contract-schedule	M&A	Disclosure schedule per purchase agreement definition
closing-checklist	M&A	Self-updating: ingests from diligence and schedule builds
ai-tool-handoff	M&A	Luminance/Kira integration — bulk extraction + QA layer
board-minutes	Board & Secretary	Calendar-detected meetings → draft minutes in house format
written-consent	Board & Secretary	Unanimous written consents with precedent search from consents repository; scope warning for major one-off actions
entity-compliance	Entity Management	Compliance calendar tracker (YAML); filing deadlines by entity and state; health audit; CT Corp report ingestion; CSV export
integration-management	M&A	Post-closing integration tracker; phased workplan (Day 1/30/90/180); Required Consents tracker with PA deadlines; contract assignment at scale (repository or manual list); weekly status reports
matter-workspace	Create, list, switch, and close matter workspaces for multi-client practices; isolates each client/matter so context does not leak across them

Public Company skills coming in next release.

Interactive commands vs. scheduled agents

The commands above run when you invoke them — for when you're working a matter. The agents below run on a schedule — for what moves while you're not looking:

Agent	Module	What it watches	Default cadence
dataroom-watcher	M&A	VDR for new document uploads; flags uploads that match high-priority categories; runs closing checklist status	Weekly

Integrations

Connect a research tool first — the citation guardrails depend on it. Without one, every cite is tagged [verify] and the reviewer note above each deliverable records that sources weren't verified. Skills work either way; a research tool (Lexis+, CourtListener) just shifts verification work off your plate.

Ships with:

• Slack — search messages, read channels, find discussions (general bucket)
• Google Drive — search, read, and fetch documents (general bucket)
• Box — data room and document management

Intralinks, Datasite, and other VDR connectors can be added to .mcp.json when partner URLs are available.

How it learns

Your practice profile at ~/.claude/plugins/config/claude-for-legal/corporate-legal/CLAUDE.md isn't static — it improves as you use the plugin. Skills tell you when an output used a default you should tune. You can re-run setup, edit the file directly, or tell a skill to record a new position.

M&A notes

• Issue extraction applies materiality thresholds — does not read every document if threshold says top N by value.
• Buy-side and sell-side are both supported. Practice Profile captures which side applies to this deal; skills adjust posture accordingly.
• AI tool handoff (Luminance/Kira) is optional. If ~/.claude/plugins/config/claude-for-legal/corporate-legal/CLAUDE.md says no tool, all extraction runs through the direct skill.
• Closing checklist initializes from the purchase agreement, then self-updates as diligence surfaces consents required.
