From 7e4201ca9903ac28be5e498dba570d2930aa3eb0 Mon Sep 17 00:00:00 2001 From: yh928 Date: Sun, 2 Aug 2026 22:30:38 +0900 Subject: [PATCH 01/31] feat(mcp): surface a server's own instructions when it has no description MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit An MCP server returns `instructions` in its `initialize` response — the server's own statement of what it is for and how to drive it. We asked for it, threw it away, and told the agent nothing. That was survivable while every connected server came from the registry inventory, which carries a curated description. Hand-entered custom servers have no such entry, so the orchestrator prompt listed them by name and tool count alone. `Connection` now keeps the `instructions` from `initialize`, and `ConnectedServerOverview` carries them through. The prompt block falls back to them only when the registry has no description — an existing description still wins, so nothing that reads well today changes — and the text is untrusted input from a third-party server, so it goes through `sanitize_for_llm` with a 600-character cap and flattened newlines before it can reach the prompt. Three tests cover the ladder: instructions used when there is no description, description preferred when there is one, and untrusted instructions sanitized.

The test asserts the rendered server line stays near the 600-byte bound for input several times that size. Description precedence, the no-description fallback, and instruction sanitization were already pinned. Adds the `[rpc]` boundary events around both `initialize` calls with `server_id`, transport, and `instructions_present`. The instruction content stays out of the log — it is untrusted remote text, and the block already scrubs it before the prompt sees it. orchestrator::prompt connected_mcp 8 pass.

The `--test-threads=1` constraint was removed because the process-global state concerns it addressed are no longer relevant with the current test architecture, and the CI path update ensures that modifications to the coverage dispatch logic correctly invalidate the module scoping cache.
