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.

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 | $0.00090 | $0.03481 |
| Opus 5 | $0.00045 | $0.01741 |
| Sonnet 5 | $0.00018 | $0.00696 |
| Haiku 4.5 | $0.00009 | $0.00348 |
Grade A, and why
build-guide 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 9d 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 — 250 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/legal-clinic-uk:build-guide
- Load
~/.claude/plugins/config/uk-legal-plugins/legal-clinic-uk/CLAUDE.md→ role (must be Supervising solicitor or barrister), practice areas, jurisdiction (E&W / Scotland / NI). - Use the workflow below.
- If the user is not the supervising solicitor or barrister, stop and redirect (students run
/legal-clinic-uk:ramp). - Walk through: practice area → intake questions → pedagogy posture → review gates → cross-plugin checks → local court/tribunal rules.
- Write
~/.claude/plugins/config/uk-legal-plugins/legal-clinic-uk/guides/<practice-area>.md. Create theguides/directory if needed. - Offer a test run — run
/legal-clinic-uk:draftunder the configured posture so the supervisor sees what a student sees.
/legal-clinic-uk:build-guide
Multiple guides are fine — one per practice area. Re-run this command to revise. Edit the guide file directly for quick changes.
Build Guide: Supervisor-Authored Practice-Area Guide
Purpose
The supervisor guide is the dial that turns student-facing skills from "get the work done" into "teach the student to do the work." Every student-facing skill in this plugin reads the guide before producing output: intake asks the questions the supervisor wants asked, drafting skills pick a pedagogy posture (assist / guide / teach), review gates route to the supervisor on the items the supervisor cares about, and cross-plugin checks wrap other-plugin skills in a supervision layer.
This skill helps a supervisor author that guide in 5-10 minutes per practice area. The guide is plain markdown at a well-known path — edit it by hand anytime.
Audience: the supervising solicitor or barrister. Not students. Students run /legal-clinic-uk:ramp and then the student-facing skills; they don't author guides.
Work-product header
Every output from this skill is a supervisor-facing configuration artifact, not student work product. Do NOT prepend [AI-ASSISTED DRAFT — requires student analysis and supervising solicitor/barrister review] to the output of this skill — that label is for student outputs. The guide file this skill writes is a supervisor configuration document; it sits next to CLAUDE.md in the plugin config directory.
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.

build-guide is a skill published in the GitHub repository uk-agents/uk-legal-plugins (9 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 90 tokens to every session and 3,481 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings.
