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 | $0.00105 | $0.02705 |
| Opus 5 | $0.00053 | $0.01352 |
| Sonnet 5 | $0.00021 | $0.00541 |
| Haiku 4.5 | $0.00011 | $0.00270 |
Grade A, and why
is-this-a-problem 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 — 157 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/is-this-a-problem
- Load
~/.claude/plugins/config/uk-legal-plugins/product-legal-uk/CLAUDE.md→ Risk calibration. - Apply the triage workflow below.
- Pattern-match. Check for common UK-specific traps.
- Answer in one minute: ✅ Fine / ⚠️ Needs a look / 🛑 Hold. One sentence why.
- If ⚠️ or 🛑: name the next step.

Matter context
Matter context. Check ## Matter workspaces in the practice-level CLAUDE.md. If Enabled is ✗ (the default for in-house users), skip the rest of this paragraph — skills use practice-level context and the matter machinery is invisible. If enabled and there is no active matter, ask: "Which matter is this for? Run /product-legal-uk:matter-workspace switch <slug> or say practice-level." Load the active matter's matter.md for matter-specific context and overrides. Write outputs to the matter folder at ~/.claude/plugins/config/uk-legal-plugins/product-legal-uk/matters/<matter-slug>/. Never read another matter's files unless Cross-matter context is on.
Destination check
Before producing output, check where it's going. If the user has named a destination (a channel, a distribution list, a counterparty, "everyone"), ask whether it's inside the legal professional privilege circle. Public channels, company-wide lists, counterparty/opposing counsel, vendors, and clients (for legal advice) can break privilege. When the destination looks outside the circle, flag it and offer (a) the privileged version for legal only, (b) a sanitised version for the broader channel, or (c) both.
Purpose
Most "quick legal question" Slacks are one of three things: (a) not a problem, say so fast, (b) a real thing that needs a real look, route it, (c) a thing that looks fine but has a UK-specific trap, catch the trap. This skill sorts in under a minute using the calibration table.
The goal is speed. The PM asked at 4:47pm. They want an answer, not a memo.
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.

is-this-a-problem 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 105 tokens to every session and 2,705 once invoked, about $0.0005 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.
