What is license-compat?

A fixed-rule checker for whether a project's software licenses and dependency licenses can be used together.

Use it to review license compatibility based on linking, distribution, and whether a dependency was modified.

It reduces the risk of overlooking obligations such as offering source code or applying the project's license when distributing software.

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	$0.00079	$0.00481
Opus 5	$0.00039	$0.00241
Sonnet 5	$0.00016	$0.00096
Haiku 4.5	$0.00008	$0.00048

Security

Grade A, and why

license-compat 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 11d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (assets/assess_license.schema.py, scripts/assess_license.py, scripts/test_assess_license_ratified.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

What it actually says

assess_license — skill (tempered by temper-skills)

You are an assistant.

The decision is frozen. Do not re-derive it from prose or your own judgment — the routing logic now lives in a deterministic decision tree (assess_license.assess_license, zero LLM calls, reviewed and version-controlled). Your job is the part the tree cannot do: turn the request into structured features, call the tree, and phrase its verdict.

How to answer

Extract these structured features from the request:
- project_license
- dependency_license
- linking
- distributing
- modified_dependency

Call the decision tree and treat its result as authoritative (bundled at scripts/assess_license.py):

from scripts.assess_license import assess_license
verdict = assess_license({"project_license": project_license, "dependency_license": dependency_license, "linking": linking, "distributing": distributing, "modified_dependency": modified_dependency})

Relay verdict to the user. Do not override it. If a feature can't be extracted, pass it as None — the tree is built to fall through safely.

Gray zones to surface

The tree flags these as underdetermined — mention the caveat when the answer touches them:

(n2) network-use scope is fact-specific — confirm deployment model
(n6) LGPL static-linking obligations are satisfiable (provide object files) — counsel can clear it

Generated by temper-skills from the original skill · 2026-07-01T12:45:19Z · model: claude-opus-4-8 via temper-skills. The decision logic is now testable (temper-skills validate) and evolvable (temper-skills incremental) — regenerate this skill when the tree changes.

Files

What ships with it

5 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.

Changes

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.

license-compat is a skill published in the GitHub repository CyrilLeMat/temper-skills (4 stars, last pushed 29d ago), licensed Apache-2.0. It adds 79 tokens to every session and 481 once invoked, about $0.0004 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 2026-08-31.
