Use for Bash 5.2+/5.3 scripts, shell CLIs, entrypoints, CI jobs, cron, text-processing pipelines, ShellCheck remediation, and shell reviews. Enforces strict mode, dispatch-table routing, fork-minimal primitives, atomic I/O, signal-safe cleanup, and pragmatic functional shell patterns.
Enforces C# + LanguageExt functional/ROP style, type discipline, runtime-record effects, Scrutor composition, and module organization standards. Use when writing, editing, reviewing, refactoring, or debugging .cs modules, implementing domain models, sealed DU hierarchies, Eff/Fin/Validation pipelines, or configuring .csproj, analyzers, or DI.
Use for PostgreSQL 18 SQL, migrations, DDL, functions, RLS policies, indexes, query plans, extensions, and SQL embedded in TypeScript via @effect/sql-pg. Enforces set-algebraic queries, schema-level invariants, current PostgreSQL features, extension-first design, tenant security, observability, and migration safety.
Enforces Python + expression style, type discipline, error handling, concurrency, and module organization standards. Use when writing, editing, reviewing, refactoring, or debugging .py/.pyi modules, implementing domain models, ROP pipelines, Protocol-driven services, or configuring pyproject.toml, Ruff, or ty.
Enforces TypeScript + Effect functional/ROP style, type discipline, polymorphic surfaces, and module organization standards. Use when writing, editing, reviewing, refactoring, or debugging .ts/.tsx modules, implementing domain models, Effect services, persistence adapters, or boundary handlers, or configuring TypeScript, Effect, or lint/type-check posture.
Generates and validates project documentation: READMEs, ADRs, changelogs, ARCHITECTURE.md, and code documentation. Use when creating, updating, or reviewing any non-code markdown artifact, README file, architecture decision record, ARCHITECTURE document, CHANGELOG entry, or code documentation (docstrings, XML docs, TSDoc). Activates for: (1) scaffolding README, CHANGELOG, ADR, CONTRIBUTING, ARCHITECTURE, or SECURITY files; (2) writing or reviewing doc comments on exported APIs; (3) auditing documentation coverage or staleness; (4) generating release notes from commit history.

Dictum: Three commands mirror MCP capabilities plus unified convenience.
Query Context7 library documentation. Matches MCP tool structure (resolve-library-id, query-docs).
[IMPORTANT] Context7 pulls up-to-date, version-specific documentation from source. Supports private documents (early access). Community-driven library coverage.
| [CMD] | [ARGS] | [RETURNS] |
|---|---|---|
| resolve | <library> [query] | Top 5 matching IDs with scores |
| docs | <library-id> <query> | Documentation filtered by query |
| lookup | <library> <query> | Resolve + docs in one call |
# Resolve library -> see options
uv run .claude/skills/context7-tools/scripts/context7.py resolve effect
# Resolve with query filter
uv run .claude/skills/context7-tools/scripts/context7.py resolve react "server components"
# Fetch docs for specific ID
uv run .claude/skills/context7-tools/scripts/context7.py docs /effect-ts/effect "Services"
# Unified: resolve + docs
uv run .claude/skills/context7-tools/scripts/context7.py lookup react "hooks"
# Unified: with version-specific query
uv run .claude/skills/context7-tools/scripts/context7.py lookup vite "v7 migration guide"
resolve: <library> [query]
library — Library name to search (required, e.g., effect, react, vite)query — Optional query to narrow resultsdocs: <library-id> <query>
library-id — Context7 library ID (required, e.g., /effect-ts/effect)query — Documentation topic to retrieve (required)lookup: <library> <query>
library — Library name (required)query — Topic to fetch docs for (required)lookup auto-selects library by: VIP status -> highest benchmark score.
Use resolve first when disambiguation needed (e.g., multiple React packages).
Commands return JSON or plain text.
| [INDEX] | [CMD] | [RESPONSE] |
|---|---|---|
| [1] | resolve | JSON array: [{id, title, score, vip}] |
| [2] | docs | Plain text documentation prefixed with [library-id] |
| [3] | lookup | Plain text documentation (same as docs) |
| [VAR] | [REQUIRED] | [DESCRIPTION] |
