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 | $0.00118 | $0.02773 |
| Opus 5 | $0.00059 | $0.01386 |
| Sonnet 5 | $0.00024 | $0.00555 |
| Haiku 4.5 | $0.00012 | $0.00277 |
Grade A, and why
deadlines 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 7d 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 — 179 lines — stays where its author put it; the contents beside it link to each section on GitHub.

- Load
~/.claude/plugins/config/uk-legal-plugins/legal-clinic-uk/CLAUDE.md→ jurisdiction, practice areas, warning-day cadence. - Use the workflow below.
- Route by flag:
--add: capture case, type, description, due date, source, owner. Write to~/.claude/plugins/config/uk-legal-plugins/legal-clinic-uk/deadlines.yaml. Check for duplicates first.--report(default): cross-case rollup — overdue, next 3d, next 7d, next 14d; by owner; by practice area; unassigned flags.--update [id]: modify fields; log note with date.--complete [id]: mark done; confirm with student that work is actually filed/submitted.--close [id]: close-without-completing; require rationale in notes.
- Confirm any write before committing.
Deadlines
Purpose
A UK law school clinic's biggest operational risk is a missed deadline. Students carry multiple cases, work part-time, and turn over every term. The Employment Tribunal's 3-months-less-one-day rule is one of the strictest limitation periods in UK law — and it is unforgiving. The supervising solicitor or barrister is professionally responsible if a deadline is missed. This skill is the central operational record.
Load context
~/.claude/plugins/config/uk-legal-plugins/legal-clinic-uk/CLAUDE.md→ jurisdiction (E&W / Scotland / NI), practice areas, deadline warning days (default 14/7/3/1), supervising solicitor/barrister~/.claude/plugins/config/uk-legal-plugins/legal-clinic-uk/deadlines.yaml— the ledger
Jurisdiction assumption. Deadline calculations and warning thresholds assume the jurisdiction set in CLAUDE.md. Limitation periods, computation-of-time rules, and court/tribunal practice vary materially between E&W, Scotland, and Northern Ireland, and between different courts and tribunals. Confirm every deadline against the governing rule with your supervisor before relying on it.
Employment Tribunal special note. The 3-months-less-one-day rule ([LIMITATION-ACT-1980]-equivalent in employment law: Employment Rights Act 1996 s 111(2) for unfair dismissal; Equality Act 2010 s 123 for discrimination) is strict and jurisdiction-specific. ACAS early conciliation pauses (does not extend) the limitation period — the ACAS certificate issue date and expiry date must be recorded alongside the deadline. Students must NOT calculate ET deadlines unassisted — they must confirm with the supervising solicitor/barrister and check current ACAS guidance.
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.

deadlines 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 118 tokens to every session and 2,773 once invoked, about $0.0006 per session on Opus 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 2026-09-03.
