clearance

clearance is a skill for Claude Code from anthropics/claude-for-legal. It costs 69 tokens per session (6,328 once invoked), scanned A, original, Apache-2.0.

A first-pass trademark search that looks for obvious legal barriers and similar marks. A trademark is a name, logo, or other sign used to identify goods or services; this tool gives a flag list, not a final legal clearance opinion.

In plain words
What is it for?
Use it when proposing a new trademark, checking whether a name may be available, or reviewing possible confusion with existing marks.
Why use it?
It can reveal visible conflicts and risk factors early, before the cost of a full professional search. A result with no obvious conflict does not prove that a mark is safe to use.

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.

Security

Grade A, and why

clearance 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 6d 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.

/clearance

This is a triage, not a clearance opinion. A trademark clearance opinion requires a full professional search and registered trademark counsel's judgment. A "no obvious conflicts" result means the triage didn't find anything — it does not mean the mark is clear. Clients have been sued over marks that passed a knockout search.

Instructions

  1. Read ~/.claude/plugins/config/claude-for-legal/ip-legal/CLAUDE.md. If it contains [PLACEHOLDER], stop and direct to /ip-legal:cold-start-interview.
  2. Follow the workflow below.
  3. Run intake (mark, goods/services, classes, jurisdictions, visual/stylization).
  4. Knockout check for intrinsic bars — generic, descriptive, deceptive, geographic, surname, false connection, prohibited matter, functional.
  5. Similar-marks search against what's connected (Solve Intelligence, CourtListener, Descrybe, or whatever MCP is available). If nothing is connected, say so in the output and proceed with the factor analysis only.
  6. Walk the applicable circuit's likelihood-of-confusion factors — du Pont / Polaroid / Sleekcraft / other. Flag each; never conclude.
  7. Write the triage memo to the matter folder (if a matter is active) or the practice outputs folder. Apply the work-product header per role.
  8. End with recommended next steps and the non-lawyer gate if the role is non-lawyer.

This skill never concludes a mark is clear. If uncertain, flag — the attorney decides.

Examples

/ip-legal:clearance "APEXLEAF for an outdoor apparel line, planned launch US + EU"
/ip-legal:clearance

(And the skill will ask for the mark, goods, classes, and jurisdictions.)


THIS IS A FIRST PASS, NOT A CLEARANCE OPINION

Say this at the top of every output. Do not drop it. Do not soften it.

This is a first pass, not a clearance opinion. A trademark clearance opinion requires a full professional search (TESS, state registries, common law sources, international registries, domain and social, trade dress and design marks where relevant) and attorney judgment on likelihood of confusion, which depends on factors a structured triage cannot fully assess. A "no obvious conflicts" result from this skill means the triage didn't find anything — it does not mean the mark is clear. Clients have been sued over marks that passed a knockout search. A registered trademark attorney evaluates before anyone adopts, files, or invests in this mark.

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.
