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 | $0.00143 | $0.01035 |
| Opus 5.5 | $0.00057 | $0.00414 |
| Sonnet 5.5 | $0.00029 | $0.00207 |
| Haiku 4.5 | $0.00014 | $0.00103 |
Grade A, and why
map-limitation-periods-l0cka 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 22d 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 — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Map Limitation Periods
Map a described cause of action to candidate limitation periods with assumptions stated, candidates for every plausible characterisation and jurisdiction, and the earliest candidate marked as the conservative marker — a triage convention, never advice.
Read the source and control method, use an approved profile per the deadline profile schema and work from the limitation registry.
Workflow
- Fix the claim and the inputs.
- Record the described facts, every plausible characterisation of the cause of action, every plausibly applicable jurisdiction and the assessment date.
- Record the lawyer-supplied accrual or discoverability date for each
characterisation as an assumption. Never derive one: a missing accrual
date makes that candidate
cannot be computed from inputs.
- Map candidates from the registry.
- For each characterisation and jurisdiction, take the candidate period
and statutory basis from the registry. Registry entries are routing
leads: verify each period relied on through the jurisdiction's checker
(
$check-commonwealth-legislation,$check-nsw-legislation,$check-victoria-legislationor the applicable sibling) at the assessment date and record the evidence state. - Flag every potentially engaged special regime and every postponement or extension provision as a flag, never a conclusion.
- For each characterisation and jurisdiction, take the candidate period
and statutory basis from the registry. Registry entries are routing
leads: verify each period relied on through the jurisdiction's checker
(
- Rank conservatively.
- Order candidates by date and mark the earliest as the conservative marker. State plainly that the marker is a triage convention and that characterisation, accrual and any extension are the responsible lawyer's calls.
- Set the human decision gate.
- Name the confirmer who must resolve characterisation, confirm the controlling candidate and enter dates in the diary system of record.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

map-limitation-periods-l0cka is a skill published in the GitHub repository ThomasMoreAI/legal-skills-open (95 stars, last pushed 15d ago), licensed Apache-2.0. It adds 143 tokens to every session and 1,035 once invoked, about $0.0006 per session on Opus 5.5. 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 2026-10-06.
