vocabulary

vocabulary is a skill for Claude Code from xiaolai/nlpm. It costs 57 tokens per session (3,999 once invoked), scanned A, original, ISC.

A vocabulary list for naming and describing NLPM commands, agents, skills, rules, and workflows. NLPM is the project’s own system of reusable natural-language development tools.

In plain words
What is it for?
Use it when writing or reviewing an NLPM artifact, or when choosing its name and wording. It helps select the project’s established nouns and verbs instead of inventing synonyms.
Why use it?
It prevents different add-ons from using inconsistent names for the same concept. The scorer and checker use it to detect wording that differs from the project’s agreed terminology.

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

vocabulary 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.

The opening of the file, as written. The whole thing — 228 lines — stays where its author put it; the contents beside it link to each section on GitHub.

NLPM Domain Vocabulary

The canonical noun-and-verb set NLPM uses to name what it does. Every artifact name, command name, agent name, rule wording, and prose description should draw from this registry. Synonyms are flagged by /nlpm:check and penalized by /nlpm:score.

Sister skill: nlpm:conventions holds upstream Claude Code framework terms (hook events, frontmatter fields, manifest keys). This skill holds NLPM-internal domain language. If a term is from Anthropic's docs, it belongs in conventions. If it is from NLPM's own corpus, it belongs here.


How this registry is built

Every term listed below has literary warrant — it appears in at least one NLPM artifact today, captured by analysis/scripts/extract-vocabulary.py. Re-run that script after adding or renaming artifacts; the freshest output lives at analysis/vocabulary-extract/summary.md. New terms enter the registry only after one of the four warrant types from analysis/vocabulary-design-principles.md (P6) is satisfied — literary warrant alone is the entry bar for terms already in use; new coinages need user, structural, or domain warrant.


Two scopes (P1)

NLPM has two declared scopes. A homonym across them is a boundary, not a collision.

Scope Lives in What it operates on
internal commands/, agents/, skills/, bin/, scripts/, project CLAUDE.md NLPM's own behavior — scoring, checking, fixing, testing, listing, trending NL artifacts in the current project.
auditor .github/workflows/auditor-*.yml, auditor/ The self-evolution pipeline that audits external repos, opens contribution PRs, tracks outcomes, refines rules.

A verb that appears in both scopes (scan, test, discover) carries the same identity criterion in both — these are sanctioned homonyms. A verb that appears in only one scope (audit, contribute, track in auditor; score, check, fix, ls, trend, init in internal) is scope-bound; using it in the other scope requires either renaming or declaring a second scope-specific definition.

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.
