uk-legal-plugins: Instructions file for Claude Code

CLAUDE.md

uk-legal-plugins CLAUDE.md is an instructions file for Claude Code from uk-agents/uk-legal-plugins. It costs 2,219 tokens per session, scanned A, original, Apache-2.0.

Repository instructions for a UK legal plugin marketplace. The marketplace contains plugins and skills for legal work and packages them for several tools that support MCP, a standard way for AI tools to use external services.

In plain words
What is it for?
Use them when editing legal-plugin prompts, skills, agents, hooks, manifests, or documentation for Claude Code, Cowork, or OpenAI Codex CLI.
Why use it?
They explain the supported client types, file layout, documentation, and validation rules so changes fit the marketplace’s packaging model.

Instructions file for Claude Code

Written for Claude Code: Claude Code plugin machinery. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions subagents.

This is uk-agents/uk-legal-plugins's own configuration. It tells Claude Code how to work on uk-legal-plugins itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything uk-legal-plugins configures →

Token cost

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.

Security

Grade A, and why

uk-legal-plugins 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 10d 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 — 155 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. uk-legal-plugins is a UK-jurisdiction legal plugin marketplace — 11 plugins, 140+ skills. Most work here is editing prompt content (skills, agents, hooks) or plugin metadata — not application code.

Target ecosystems

These plugins reach three MCP-speaking client ecosystems via dual-manifest packaging (.claude-plugin/plugin.json + .codex-plugin/plugin.json per plugin, sharing the same skills/ + .mcp.json):

Ecosystem Audience Reaches via
Claude Code Developer + lawyer-developers .claude-plugin/plugin.json
Cowork (Anthropic) Anthropic collaborative env Same as Claude Code
OpenAI Codex CLI OpenAI developer audience .codex-plugin/plugin.json

ChatGPT consumer (~80M/week) is NOT reachable through these plugins — ChatGPT supports MCP tools only, no skills, no resources, no prompts. ChatGPT users connect directly to uk-legal-mcp.fly.dev/mcp; for them, the MCP server's tool descriptions are the only workflow-teaching layer. See uk-legal-mcp/docs/chatgpt-workflow-encoding.md (in the sibling repo).

Documentation index

In docs/:

  • SPEC.md — pre-existing specification
  • skill-gaps-and-design.md — 5 new skills closing the dogfeed-failure workflows (find-member-contribution, find-case-by-party-verify, oscola-build-citation, statute-amendments-trace, bill-debate-trace)
  • distribution-strategy.md — distribution decision (Option C1: single free public repo), dual-manifest plugin pattern, future revenue paths (recorded; not implemented)

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.
