Why

Both agents pin a tools: list in their frontmatter, and a pinned list excludes any tool not named, so neither agent could use Claude Code's LSP tool. LSP is the generic language-server client; which servers exist is a per-user plugin choice (typescript-lsp, pyright-lsp, gopls-lsp, ...), so adding the tool keeps the handbook language-neutral. When no server is configured for a file type the tool returns an error and the agent continues, so it costs nothing in repositories without an LSP plugin.

What

The task-executor and wave-reviewer agents may now call the LSP tool for definitions, references, hover types and symbols when a language server is available, and are told not to rely on it being present. No language-specific LSP configuration is added.

Changes

• Add LSP to the end of the tools: list of agents/task-executor.md and agents/wave-reviewer.md, and add one sentence to the executor's "Prove it" step and to the reviewer's read-only paragraph saying the tool may be used for definitions, references, hover types and symbols when a language server is available and must not be relied on. A pinned tools: list excludes any tool not named, and the generic client keeps the handbook language-neutral.
• Add LSP to the allowlist of tool names in checks/test_agents.py. The check fails on the new frontmatter otherwise, and the allowlist's own comment says to extend it there when an agent needs another tool.
• Bump the plugin version to 0.15.0 in plugins/freethinking/.claude-plugin/plugin.json, so installs pick up the new agent frontmatter, as every prior change to the plugin did.

Testing

make validate passed: the 23 Python checks under checks/, and claude plugin validate --strict on the marketplace, the plugin and the skills.

No eval was run. The eval sandbox has no language server and the agent cases' allowed_tools do not include LSP, so no existing case exercises the change; the added sentences can only be judged by reading.

Risk and rollout

None. In a repository without an LSP plugin the tool returns an error and the agent carries on, as the added sentences say.

Notes for reviewers

• The author did not answer, for any change, what it does not cover, what would break it, or what a reviewer should question; read the two added sentences for a reading the agents could take wrong.
• The version bump and the allowlist edit were not named in the request; the request asked for the two agent files and nothing else. Drop either if it should not be here.
