Claude for Legal is a collection of AI agents, skills, and data connectors for legal work such as commercial, privacy, employment, litigation, regulatory, and intellectual-property matters. Lawyers and legal teams use it through Claude Cowork, Claude Code, or the Claude Managed Agents API, with attorney review required for every output. The catalogue entries are its workflow plugins, skills, agents, and connectors.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00082 | $0.03497 |
| Opus 5.5 | $0.00033 | $0.01399 |
| Sonnet 5.5 | $0.00016 | $0.00699 |
| Haiku 4.5 | $0.00008 | $0.00350 |
Grade A, and why
gap-surfacer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 23d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 243 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Gap Surfacer
Owner notifications: on by default. To opt an owner out, leave
owner_slackempty.
Per-send confirmation — no exceptions
Before sending ANY Slack message (assignment notice, overdue reminder, bulk notification, status report):
- Show the user exactly what you're about to send and to whom: "I'm about to send this to [N] people: [preview]."
- Wait for an explicit yes.
- If the message contains any citations, deadlines, or compliance conclusions, add: "⚠️ The citations in this message are unverified — I'm not confirming they're current before sending. Do you want me to add a 'verify before acting' line?"
- Never send without the confirm. Not on a cadence. Not in a batch. Not because it was sent yesterday.
Auto-send without confirmation is the most irreversible action in this plugin, sending content this plugin's own footer says may be wrong, to people who have no way to check. That combination does not get to skip review.
Matter context
Matter context. Check ## Matter workspaces in the practice-level CLAUDE.md. If Enabled is ✗ (the default for in-house users), skip the rest of this paragraph — skills use practice-level context and the matter machinery is invisible. If enabled and there is no active matter, ask: "Which matter is this for? Run /regulatory-legal:matter-workspace switch <slug> or say practice-level." Load the active matter's matter.md for matter-specific context and overrides. Write outputs to the matter folder at ~/.claude/plugins/config/claude-for-legal/regulatory-legal/matters/<matter-slug>/. Never read another matter's files unless Cross-matter context is on.
Purpose
Gaps get found and then forgotten. This skill tracks them until they're closed and notifies the people responsible for closing them.
The tracker
Lives at ~/.claude/plugins/config/claude-for-legal/regulatory-legal/gap-tracker.yaml:
Note on comment-tracker.yaml:
~/.claude/plugins/config/claude-for-legal/regulatory-legal/comment-tracker.yamlis a sibling file owned by the comments skill. It is written to by reg-feed-watcher (which logs NPRMs automatically) and the comments skill (which tracks user-initiated comment decisions). This skill does not read or cross-reference it. If you modify the comment-tracker schema, update both actual consumers.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

gap-surfacer is a skill published in the GitHub repository anthropics/claude-for-legal (9,693 stars, last pushed 2d ago), licensed Apache-2.0. It adds 82 tokens to every session and 3,497 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-23.
Other skills, from other repositories
vendor-review
Evaluate a vendor — cost analysis, risk assessment, and recommendation. Use when reviewing a new vendor proposal, deciding whether to renew or replace a contract, comparing two vendors side-by-side, or building a TCO breakdown and negotiation points before procurement sign-off.
patent-docket
A workflow coordinator for patent case files, from an inventor's technical disclosure to patent application documents. A patent docket is the tracked record of a patent matter, including its stage, questions, drafts, and handoffs.
hr-pro
Professional, ethical HR partner for hiring, onboarding/offboarding, PTO and leave, performance, compliant policies, and employee relations. Ask for jurisdiction and company context before advising; produce structured, bias-mitigated, lawful templates.
vendor-evaluation
Evaluate, select, and contract with vendors and SaaS tools. Use this skill when comparing alternatives, running an RFP, scoring vendors against criteria, negotiating contracts, planning a switch, or assessing a vendor's risk. Triggers on vendor evaluation, RFP, vendor selection, build vs buy, SaaS evaluation, vendor…
performance-management
Runs performance systems that change behavior — expectations, feedback, review cycles, calibration, and handling underperformance. Use this to design or fix a review process, run calibration, write or coach on feedback, address sustained underperformance, or work out why reviews consume weeks and change nothing.
