What it does

Deadlines is an agent skill from anthropics/claude-for-legal, published by the product's own GitHub organization. Track case deadlines — add, cross-case rollup report, update, complete, close. Warns at configurable thresholds (default 14/7/3/1 days); overdue items stay flagged until resolved. The operational record for a clinic workload. Use when a student or supervisor needs to add a deadline, ask what's due this week, get a deadline report, or update a case deadline.

Its SKILL.md is about 2.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: A suite of plugins for legal workflows. The licence is Apache-2.0.

When your agent uses it

  • Supervisor needs to add a deadline
  • Ask whats due this week
  • Get a deadline report
  • Update a case deadline

Example prompts

  • “/deadlines”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Load ~/.claude/plugins/config/claude-for-legal/legal-clinic/CLAUDE.md → jurisdiction, practice areas, warning-day cadence.
  2. Use the workflow below.
  3. Route by flag
  4. Confirm any write before committing.

What it can do on your machine

Read from SKILL.md and the folder at commit 4a6c651. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Deadlines loads about 2.8k tokens when it runs. Until then it costs about 92 tokens; SKILL.md has 1,304 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~92
When it runs · the whole SKILL.md, loaded when a task matches
~2.8k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

  2. Use the workflow below.
  3. Route by flag:
    • --add: capture case, type, description, due date, source, owner. Write to ~/.claude/plugins/config/claude-for-legal/legal-clinic/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.
  4. Confirm any write before committing.

Deadlines

Purpose

A clinic's biggest operational risk is a missed deadline. Students carry multiple cases, work part-time, turn over every semester. Deadlines that live only in individual students' heads get dropped at handoff, get forgotten during finals week, get missed when a student unexpectedly withdraws from the clinic. This skill is the central operational record.

The supervising attorney is on the hook if a deadline is missed. The skill is calibrated to that stakes level — warnings fire early, overdue items stay visible until explicitly resolved, handoffs (via /semester-handoff) pull the deadline list forward to the next student.

Load context

  • ~/.claude/plugins/config/claude-for-legal/legal-clinic/CLAUDE.md → jurisdiction, practice areas, deadline warning days (default 14/7/3/1), supervising attorneys
  • ~/.claude/plugins/config/claude-for-legal/legal-clinic/deadlines.yaml — the ledger

Jurisdiction assumption. Deadline calculations and warning thresholds assume the jurisdiction set in CLAUDE.md. Deadlines, tolling rules, computation-of-time rules, and local court practices vary materially by jurisdiction and by specific court. If a matter involves a different state, a specific court's local rules, or a federal vs. state forum question, confirm the deadline against the governing rule with your supervisor before relying on it.

Modes

Flag: --add | --report | --update | --complete | --close (default: report)

--add — log a new deadline

Inputs:

  • Case ID + name (which case)
  • Practice area
  • Type (filing / hearing / statute-of-limitations / discovery / cure-period / response / notice / other)
  • Description — one line of what's due
  • Due date (and time + timezone if applicable)
  • Source — where the deadline came from (court order served 2026-04-20, statute 8 USC § 1229a, cure period in contract §7)
  • Owner student — the student responsible

The skill generates an id slug automatically: [case]-[short-desc]-[YYYY-MM].

Extraction from other skills: when /client-intake, /draft, or /status surface a deadline in their output, they should hand off to this skill with pre-populated fields. Student confirms and adds.

Pre-add check: if a deadline with the same case_id + type + due_date already exists, flag as likely duplicate and ask before adding.

Plausibility sanity band. After the student enters a due date, do NOT compute or verify — but apply a rough plausibility check against typical ranges for the filing type, and flag the student if the date falls far outside. This is scaffolding to catch gross errors in the student's own math, not an alternative to computing against the rule.

Bands are jurisdiction-keyed. Load the band file for this clinic's jurisdiction from references/plausibility-bands/{state}.md where {state} is the two-letter code from ~/.claude/plugins/config/claude-for-legal/legal-clinic/CLAUDE.md → clinic jurisdiction (and federal always loads alongside). The legal-clinic plugin ships references/plausibility-bands/CA.md (fully populated) and references/plausibility-bands/IL.md (placeholder structure) as starting points.

Hard stop at cold-start if the band file is missing. If references/plausibility-bands/{state}.md does not exist for the clinic's jurisdiction, do NOT silently run without plausibility checks. At cold-start, tell the supervisor:

"I don't have deadline plausibility checks for [state] — the sanity band for this clinic's jurisdiction isn't in the shipped reference files. I can still track deadlines (add, report, update, complete, close), but I cannot sanity-check them against typical ranges. Here's how to build the band file from your state's rules: copy references/plausibility-bands/IL.md as a template, fill in one row per deadline type your clinic sees most (typical range, triggering-event handling, computation-of-time rule, short cite), save at references/plausibility-bands/{state}.md, and re-run /legal-clinic:deadlines. Until then, every deadline I accept will carry warnings: no-plausibility-band and your review should treat dates as unchecked."

Do not fall back to the CA table for a non-CA clinic. The silent-degradation case — shipping a California sanity check to an Illinois clinic — is the failure this fix exists to close.

Sanity check logic:

  1. Load the bands table for this clinic's jurisdiction from references/plausibility-bands/{state}.md (plus federal-always).
  2. After the student enters due:, compare to triggering-event date + typical range for that type: (if a typical range exists in the loaded band file for the filing type).
  3. If inside the range, write the entry. Say nothing — the band exists to catch errors, not to congratulate correct math.
  4. If outside the range by a material margin, stop before writing and say:

    The date you entered falls outside the typical range for [type] in [jurisdiction]. [Type] deadlines for [filing type] typically fall ~[range] after [triggering event]. Your entry: [date], which is [N] days from [triggering event]. Re-check your calculation against [cited rule from the band file] and the jurisdiction's computation-of-time rule. If your calculation is correct (local rule exception, atypical triggering event, tolling, waiver), confirm and I will add the entry as-is. Otherwise, recompute and re-run /deadlines --add.

  5. If no band is known for this type: (unusual filing, non-standard deadline), do not sanity-check — write the entry and note in the warnings: field that no plausibility band applies.
  6. If the band file is missing entirely for this jurisdiction, the hard stop above applies at cold-start; in steady-state (supervisor acknowledged the gap and proceeded), every entry is written with warnings: no-plausibility-band.

The skill does not compute. If the student enters [VERIFY] in the due: field because they haven't done the math yet, write the entry with due: [VERIFY] — the sanity band runs only when the student supplies a concrete date. The computation stays with the student and supervisor.

## Unassigned deadlines

[list — flag if any active deadline has no owner_student]
--update — modify an existing deadline

Common updates: due date changed (court continuance), owner changed (reassignment), notes added.

Every update writes a dated note inline; history is visible in the entry.

--complete — mark done
  • Sets status: completed, completed_date: [today].
  • Confirms with the student that the actual work is done and filed/submitted.
  • Removes from active reports but stays in the yaml.
--close — close without completing

For deadlines that no longer apply — case settled, motion withdrawn, client dropped the matter. Requires a notes: entry explaining why.

Warning cadence

Per ~/.claude/plugins/config/claude-for-legal/legal-clinic/CLAUDE.md deadline warning days. Default 14, 7, 3, 1.

Warnings don't auto-surface — this plugin has no scheduled/agent behavior. But any time /deadlines is invoked (or /status, which routes to this skill for deadline checks), the report pulls forward anything hitting a warning threshold.

If a deadline passes its due date without being marked complete, it moves to status: overdue and stays there in every report until explicitly resolved. Overdue deadlines do not auto-close.

Integration

  • /client-intake: when intake surfaces a timeline urgency (eviction notice date, asylum filing deadline, hearing date), offer to /deadlines --add with pre-populated fields.
  • /draft: when a filing draft references a deadline (answer due, objection window), offer to add.
  • /status: the status skill reads ~/.claude/plugins/config/claude-for-legal/legal-clinic/deadlines.yaml for the relevant case and includes upcoming deadlines in its output.
  • /semester-handoff: reads deadlines.yaml to identify all active deadlines across departing-student cases; each handoff memo carries the deadlines forward.
  • /supervisor-review-queue (if formal review enabled): deadlines near their cutoff get priority in the review queue.

What this skill does not do

  • Calculate deadlines from triggering events. If a complaint was served today and the answer is due in 21 days per local rules, the skill doesn't do that math — the student does, using the rule, and logs the resulting date. (Doing the math autonomously creates a liability the skill shouldn't own; rules vary by jurisdiction and court.)
  • File or serve anything. The skill tracks dates; filing happens outside the plugin.
  • Auto-notify. No scheduled notifications. The report surfaces warnings when invoked; it doesn't push. A scheduled cron could be added later but would need explicit professor opt-in per clinic.
  • Override local rules. If the student logs a due date that contradicts local rules, the skill doesn't catch it. Another reason to calendar with [VERIFY: confirm against local rule] for any non-routine deadline.
