Pubmed MCP Server

Scaffold a new MCP tool definition. Use when the user asks to add a tool, create a new tool, or implement a new capability for the server.

API reference for all utilities exported from `@cyanheads/mcp-ts-core/utils`. Use when looking up utility method signatures, options, peer dependencies, or usage patterns.

Reference for core and server configuration in `@cyanheads/mcp-ts-core`. Covers env var tables with defaults, priority order, server-specific Zod schema pattern, and Workers lazy-parsing requirement.

McpError constructor, JsonRpcErrorCode reference, and error handling patterns for `@cyanheads/mcp-ts-core`. Use when looking up error codes, understanding where errors should be thrown vs. caught, or using ErrorHandler.tryCatch in services.

Exercise tools, resources, and prompts against a live HTTP server via MCP JSON-RPC over curl. Starts the server, surfaces the catalog, runs real and adversarial inputs, measures every call (bytes, token estimate, wall-clock) and weighs the catalog, and produces a tight report with concrete findings and numbered follow-up options. Use after adding or modifying definitions, or when the user asks to test, try out, or verify their MCP surface.

Land working-tree changes as logical commits — the work grouped by concern, topped by a release commit (version bump, changelog, regenerated artifacts). Verify, commit. Stops at "committed locally on main" — or, when the project releases through a release PR, at "release branch pushed, PR open". No tag, no push to main, no publish: the release-and-publish skill merges, tags, and ships from here. Distilled from the git_wrapup_instructions protocol.

Cloudflare Workers deployment using `createWorkerHandler` from `@cyanheads/mcp-ts-core/worker`. Covers the full handler signature, binding types, CloudflareBindings extensibility, runtime compatibility guards, and wrangler.toml requirements.

API reference for built-in service providers (LLM, Speech, Graph). Use when looking up service interfaces, provider capabilities, or integration patterns.

Catalog of OpenTelemetry instrumentation built into framework `@cyanheads/mcp-ts-core` — spans, metrics, completion logs, env config, runtime caveats, custom instrumentation patterns, and cardinality rules. Use when enabling OTel export, adding custom spans or metrics in services, debugging missing telemetry, looking up attribute names, or deciding what's safe to put on a metric attribute vs. a span.

Pick and run a multi-phase workflow that chains foundational task skills (`git-wrapup`, `release-and-publish`, `maintenance`, `field-test`, `setup`, etc.) end-to-end. Routes user intent to a workflow file under `workflows/` — greenfield builds, maintenance + release, field-test + fix, or known-work + release. Single source for the universal rules (no commits without authorization, no destructive git, no marketing language), the orchestrator posture (own the goal, ground sub-agents in primary sources, verify against the goal), and the sub-agent strategy (orient block, parallel fanout, isolation, normalization) that apply across every workflow. Sub-agents are an optional capability — workflows run linearly when fanout isn't available.

Post-session code review and cleanup against a working tree of changes. Analyzes `git diff` to simplify, consolidate, and align changed code with the existing codebase — modernize syntax, remove unnecessary complexity, consolidate duplicated logic, catch efficiency issues. Use after a substantive working session, or when asked to clean up, simplify, reduce slop, consolidate, modernize, tighten up, or de-slop code. For `@cyanheads/mcp-ts-core` projects, includes specific transformations for tool/resource/prompt definitions, the ctx pattern, error factories, and framework idioms.

Design the tool surface, resources, and service layer for a new MCP server. Use when starting a new server, planning a major feature expansion, or when the user describes a domain/API they want to expose via MCP. Produces a design doc at docs/design.md that drives implementation.

Review pass on an open release PR (`release/<version>` → `main`) — the step between `git-wrapup` and `release-and-publish` when a project releases in gated release PR mode. Reads the PR's commit range through the `code-simplifier` lens plus a correctness review, verifies whatever an automated reviewer left on the PR, lands fixes as fixup commits autosquashed back into the stack, force-with-lease pushes the release branch, keeps the PR body in sync with what ships, and leaves one summary comment. The only agent role that both edits and commits — and it never tags, merges, touches `main`, or publishes.

Ship a release end-to-end across every registry the project targets (npm, MCP Registry, GitHub Releases for `.mcpb` bundles, GHCR). Runs the final verification gate, fast-forwards `main` when the release rode a release PR, creates the annotated tag on the commit `main` now points at, pushes commits and tags, then publishes to each applicable destination. Assumes git wrapup (version bumps, changelog, commit stack — and in release PR mode, the pushed branch and open PR) is already complete — this skill is the post-wrapup merge + tag + publish workflow. Retries transient network failures on publish steps; halts with a partial-state report when retries are exhausted or the failure is terminal.
