| Tool | Description | Behaviour |
|---|---|---|
| worlds_advise_hard_problem | Choose the maximum-depth model-and-effort pairing for one difficult problem within the caller's actual CLI set. For a single CLI it selects that provider's strongest catalog role; with multiple CLIs it returns provider candidates but does not invent a universal cross-provider winner. It uses single-task depth, never ultra or ultracode orchestration, defaults to read-only, and does not launch a CLI or grant permissions. | Read-only |
| worlds_compare_cli_workflows | Find evidence for the same task across Claude Code, Codex, and Grok Build without pretending their commands or authority models are identical. Returns separately ranked groups with source dates and canonical links. Best for questions such as configuring MCP, repository instructions, approvals, subagents, or headless CI. | Read-only |
| worlds_get_cli_command | Return one current command path with all captured flags, arguments, value shapes, availability, risk, release metadata, and official source links. Accepts a stable id or full command path. | Read-only |
| worlds_get_cli_configuration | Search configuration keys and environment-variable names for one CLI. Returns public schema metadata and source links, never local values. | Read-only |
| worlds_get_cli_workflow | Find one provider-specific workflow and its recorded command steps without translating flags between providers. | Read-only |
| worlds_get_document | Read the bounded public excerpt and metadata for one source-checked CLI manual returned by worlds_search_knowledge. Follow canonical_url for the complete manual. Structured CLI command tools remain complete. | Read-only |
| worlds_list_catalog | Return public corpus counts, supported worlds, languages, products, source-quality counts, the build commit, and the current publication gate. This public DTO deliberately excludes local paths, package names, and private repository URLs. | Read-only |
| worlds_list_cli_models | Return dated, source-grounded model catalogs for Claude Code, Codex, and Grok Build, including selector syntax, per-model effort support, availability constraints, and provider-native orchestration modes. These are snapshots; verify the live account catalog before launch. | Read-only |
| worlds_list_cli_versions | Return the exact release snapshot, capture date, factual entity counts, official sources, generated website reference, and drift status for all three CLIs. | Read-only |
| worlds_plan_cli_work | Create a read-only, dependency-aware work plan across Claude Code, Codex, and Grok Build. It selects a concrete dated-catalog model and supported native effort for each workstream, while keeping CLI fit, orchestration, permissions, handoff context, and verification separate. Routing is continuity-first and does not claim benchmark superiority, launch another CLI, or enable permission bypass. Clients that support MCP prompts can enter the same workflow through the `worlds_plan_model_aware_work` prompt (or `worlds_consult_hard_problem` for one hard problem). | Read-only |
| worlds_search_cli_reference | Search current command paths, flags, interactive commands, configuration names, environment-variable names, workflows, and release drift for Claude Code, Codex, and Grok Build. Results contain factual metadata and official source links. | Read-only |
| worlds_search_knowledge | Search 162 multilingual, source-checked operating manuals for Claude Code, Codex, and Grok Build: 18 CLI usage and feature modules per product in English, Traditional Chinese, and Japanese. Website articles, news, newsletters, opinion, and release archives are not in this corpus. Returns bounded excerpts, commands when present, canonical links, official sources, and review dates. It never modifies state. | Read-only |
