A deadline tracker for cases handled by a UK law clinic. It records due dates, owners, case details, and whether work is overdue or completed.

It helps students and supervisors add, update, complete, close, and review deadlines across cases, including overdue work and upcoming dates.

It reduces the risk of missing filing dates or other time limits when students are handling several cases and may change each term.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00118	$0.02773
Opus 5.5	$0.00047	$0.01109
Sonnet 5.5	$0.00024	$0.00555
Haiku 4.5	$0.00012	$0.00277

Security

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 1mo 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.

/legal-clinic-uk:deadlines

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.
