Added
- Default archive exemption for code/doc MCP fetchers — MCP tools whose whole purpose is returning verbatim code or docs inline (octocode
githubGetFileContent/localGetFileContent, context7query-docs, official GitHubget_file_contents, deepwikiread_wiki_contents) are no longer compressed to a preview by default. Previously the PostToolUse optimizer cut these to ~1500 chars, defeating the tool. - Scoped to content fetchers only — search / tree / list tools still compress, preserving the optimizer savings.
TOKEN_OPTIMIZER_ARCHIVE_EXEMPT_TOOLSis now additive on top of the defaults (one-line to exempt more tools); setTOKEN_OPTIMIZER_ARCHIVE_EXEMPT_DEFAULTS=offto drop the built-ins.
