Nexus Tool Schemas

Context: the exporter boots the agent registry headlessly and asks the live ToolCliNormalizer for each tool's CLI schema, so the JSON is the caller's-eye view of the tools rather than a parse of the TypeScript. It runs with no Obsidian, no vault and no build — but it does need npm install, and it writes to two different files for two different jobs.

Workflow

1. Decide which job this is. The answer is the output path, and choosing it by default is the standard failure here — the default path is a scratch file nothing reads.
   • Reading, answering a question, inspecting a subset → protocols/export-subset.md
   • Refreshing the catalog the repo ships and tests against → protocols/refresh-catalog.md
2. Run that protocol end to end. You MUST NOT hand-write or hand-patch either JSON file: both are generated, and an edited catalog makes the drift test the only thing standing between a wrong doc and a caller.
3. Validate what you produced with scripts/check_catalog.py before reporting it, and treat a non-zero exit as a stop.
4. At the end of a session that used this skill, run protocols/self-refine.md.

Map

• protocols/ the two export jobs, plus self-refine.
• references/ consumers.md (which file each reader expects, and what breaks when it is stale) and exporter-internals.md (how the headless boot works, what it needs, and its failure modes).
• scripts/check_catalog.py validates an exported catalog; scripts/check_exporter_coverage.py catches an agent the exporter cannot see. Run them, do not reimplement.
• refinement-log.md what past sessions changed here and why.

Siblings

• Adding or renaming an agent or tool, or a command that does not resolve: nexus-agents. It owns the slug-to-CLI-name transform (cli_name.py) and the checker for commands written in docs (check_documented_commands.py).
• Jest lanes, the shipped-docs gate and how to make a failing test fail for the right reason: nexus-testing.
• Shipping the refreshed catalog in a version: nexus-release.
