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.

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 | $0.01479 | $0.01479 |
| Opus 5 | $0.00740 | $0.00740 |
| Sonnet 5 | $0.00296 | $0.00296 |
| Haiku 4.5 | $0.00148 | $0.00148 |
Grade A, and why
claude-for-legal CLAUDE.md 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 12d 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 — 131 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
Guidance for working on this repo. claude-for-legal is a Claude Code plugin
marketplace — twelve first-party legal plugins, one vendor plugin, and five
managed-agent cookbooks. Most work here is editing prompt content (skills,
agents, hooks), plugin metadata, or cookbook config — not application code.
Layout
.claude-plugin/marketplace.json # the marketplace manifest — one entry per plugin
<plugin>/ # 12 first-party plugins (commercial-legal, privacy-legal, ...)

Validation — run before opening a PR
This repo follows the same conventions anthropics/claude-plugins-official
enforces in CI. Run the equivalent checks locally:
# 1. Marketplace + per-plugin schema validation (source of truth)
claude plugin validate .claude-plugin/marketplace.json
for d in */; do [ -f "$d/.claude-plugin/plugin.json" ] && claude plugin validate "$d"; done
claude plugin validate external_plugins/cocounsel-legal
# 2. Cookbook tool-scope lint (orchestrators must not over-grant tools)
python3 scripts/lint-tool-scope.py
# 3. JSON/YAML sanity
python3 -c "import json,glob; [json.load(open(f)) for f in glob.glob('**/*.json', recursive=True)]"
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.
