Expose advisor tools from explicit read-only annotations instead of a static allowlist. Restrict advisor MCP discovery and dispatch to tools that opt into read-only use without destructive hints. Document the MCP annotation trust boundary and cover the production advisor tool set, including webFetch, with regression tests. Co-authored-by: GPT-5 Codex <codex@openai.com>

Advisor tool exposure now comes from tool annotations instead of the previous static allowlist. This lets the advisor receive any host-marked read-only tool while keeping recursive, mutating, and user-visible tools out of the advisor runtime.
MCP Read-Only Filtering
searchMcpTools and callMcpTool can now be constructed in read-only mode for the advisor. They expose only MCP tools with readOnlyHint: true and reject tools with destructiveHint: true.
Tool Metadata
Local read-only tools now declare MCP-style annotations, including webFetch, webSearch, file reads, system time, and read-only Slack surfaces. The advisor spec documents the trust boundary for remote MCP annotations.
