Add HelpBuiltin that provides runtime tool schema introspection: - `help --list` lists all tool names + descriptions - `help <tool>` prints human-readable usage - `help <tool> --json` prints machine-readable JSON schema (pipeable to jq) Add `compact_prompt(bool)` builder method to ScriptedToolBuilder. When enabled, system_prompt() emits only tool names + one-liners and instructs the LLM to use `help` for full details — reducing context window usage for large tool sets. 8 new tests. Update spec 014. Closes #519
Extend ToolDef with tags and category fields for progressive discovery. Add DiscoverBuiltin with --categories, --category, --tag, --search, and --json modes. Register alongside help builtin. 11 new tests. Update spec 014. Closes #521
