-**Hooks are structurally non-blocking** (exit code 0, every failure path).
-For Claude Code, the `PreToolUse` hook intercepts `Grep`/`Glob` (never `Read` —
-gating `Read` breaks the read-before-edit invariant) and, when the search
-token matches indexed symbols, injects them as `additionalContext` via
-`search_graph` so the agent gets structured context alongside its normal
-search results. For Codex, Gemini CLI, and Antigravity, a `SessionStart` hook
-injects a one-line code-discovery reminder as session context (Gemini CLI also
-keeps its `BeforeTool` reminder).
-The installed Claude shim file is named `cbm-code-discovery-gate` for
-backward compatibility with existing installs; despite the legacy name it
-never gates and never blocks.
+### Sessions, compaction, and subagents
+
+Hooks installed by this project are fail-open and context-only. Claude Code's
+`PreToolUse` observes `Grep`/`Glob` and injects matching graph symbols as
+`additionalContext`; `Read` only adds a coverage warning when the graph could not
+fully parse a file. It never denies or replaces the requested tool call.
+
+Claude Code, Codex CLI, Qwen Code, GitHub Copilot CLI, and VS Code's Copilot
+runtime receive paired session/subagent context where the vendor exposes a
+documented context-output contract. Codex users must review and trust installed
+hooks through `/hooks`; changing a hook definition changes its trust hash, so an
+update can require re-trust. On macOS/Linux, Qoder and Kimi use the current
+`UserPromptSubmit` event, while Hermes uses `pre_llm_call`; Kimi and Hermes also
+retain their documented Windows execution paths. Devin installs
+`UserPromptSubmit` and `PostCompaction` on macOS/Linux and adds `SessionStart`
+only when Claude's equivalent managed hook is not present. GitLab Duo gets a
+narrowly scoped macOS/Linux user `SessionStart` entry on its experimental hook
+surface. Qoder, GitLab Duo, Devin, and Factory hooks are withheld on Windows
+because those vendors do not document a deterministic shell/executor contract
+there. Gemini CLI, Factory Droid, and Augment expose reliable session
+augmentation but no equivalent documented child-start context.
+
+For runtimes without a stable context-producing lifecycle event, durable files
+carry the contract across fresh sessions and compaction: verify the graph project
+and index freshness, query structural facts in the parent, then pass the project,
+qualified symbols, paths, and call-chain evidence in every delegated task.
+Claude, Gemini, Kiro, Qwen, CodeBuddy, Kilo, Vibe, and Qoder receive explicit
+graph-tool subagent profiles; Kiro embeds only this MCP server, while Kilo and
+Vibe enumerate the read-only query tools instead of granting a server wildcard.
+Junie and Factory can restrict the child to this server, but their current
+schemas do not provide per-MCP-tool filtering, so the profile also carries a
+no-state-change contract. Rovo, Cursor, Pochi, and Cline use parent handoff where
+direct child MCP is unavailable or unsafe; Pochi is limited to `readFile`, and
+Cline child agents cannot use MCP.
+
+Cline's file hooks auto-activate when present, and current Cline does not
+reliably consume their context output, so automatic adapters are withheld and
+older owned adapters are cleaned up. CodeBuddy's beta, version-gated hooks are
+not auto-installed. Junie's EAP
+`SessionStart` output is documented as ignored, so no context hook is installed.
+Cursor context
+hooks are withheld: session context injection has a known race, `subagentStart`
+is control-only, and read-only subagents cannot safely receive MCP access. Rovo
+has no documented session context-output hook, and Bob
+documents neither a suitable hook nor a custom-agent surface. Those surfaces are
+not approximated with invented augmentation. Kimi plugins, Amp plugins, and
+GitLab experimental global skills remain opt-in.
+
+OpenClaw reinjects the `Codebase Knowledge Graph (codebase-memory-mcp)` AGENTS
+section after compaction and places the same guidance in `TOOLS.md`, the bootstrap
+files inherited by its subagents. Automatic augmentation covers the active/default
+workspace. Separate `agents.list[].workspace` directories require making that
+workspace active for installation or copying the managed block there.
+
+The installed Claude shim is named `cbm-code-discovery-gate` for backward
+compatibility; despite the legacy name, it never gates or blocks.
+
+### Manual or UI-managed integrations
+
+These are intentionally not counted as automatic installs: Qodo MCP is added
+through its UI and may be governed by enterprise allowlists; Warp MCP is managed
+through Warp Drive/UI or per invocation (only the shared skill is automatic);
+JetBrains AI Assistant / ACP is IDE-managed; GitHub Copilot coding agent, Jules,
+and CodeRabbit are cloud/repository-managed; Replit exposes a remote/service
+integration rather than a stable local user-global client; BLACKBOX AI does not
+document a stable arbitrary user-global MCP/instruction/agent schema; Plandex has
+no stable global registry safe to mutate; and SWE-agent uses explicit YAML and is
+no longer a suitable automatic global target.

 ## Installation

@@ -29,7 +29,13 @@ Restart your agent. Say **"Index this project"** — done.
 - **Plug and play** — single static binary for macOS (arm64/amd64), Linux (arm64/amd64), and Windows (amd64). No Docker, no runtime dependencies, no API keys.
 - **159 languages** — vendored tree-sitter grammars compiled into the binary. Nothing to install, nothing that breaks.
 - **120x fewer tokens** — 5 structural queries: ~3,400 tokens vs ~412,000 via file-by-file search.
- **11 agents, one command** — `install` auto-detects Claude Code, Codex CLI, Gemini CLI, Zed, OpenCode, Antigravity, Aider, KiloCode, VS Code, OpenClaw, and Kiro.
+- **43 supported automatic/conditional client surfaces** — `install` configures the appropriate MCP, durable-context, and documented hook surfaces without widening client permissions.
+- **Detected automatically (37)** — Claude Code, Codex CLI, Gemini CLI, Zed, OpenCode, Antigravity, Aider, KiloCode, VS Code, Cursor, Windsurf, Augment / Auggie, OpenClaw, Kiro, Junie, Hermes, OpenHands, Cline, Warp, Qwen Code, GitHub Copilot CLI, Factory Droid, Crush, Goose, Mistral Vibe, Qoder CLI, Kimi Code CLI, GitLab Duo CLI, Rovo Dev CLI, Amp, Devin CLI / Local, Tabnine, Amazon Q Developer IDE, CodeBuddy Code CLI, IBM Bob Shell, Pochi, and Pi.
+- **Conditional or explicit (6)** — Continue / cn, Visual Studio, TRAE, Roo Code, IBM Bob IDE, and Sourcegraph Cody. Bob IDE is touched only when `~/.bob/mcp.json` already exists.
+- **New documented adapters** — CodeBuddy uses `~/.codebuddy/.mcp.json` while preserving active older files; Bob Shell uses `~/.bob/mcp_settings.json`; Pochi uses the `mcp` section in `~/.pochi/config.jsonc`; Amazon Q Developer IDE defaults to `~/.aws/amazonq/default.json` while preserving either documented alternative.
+- **Lifecycle hooks stay conservative** — Kimi uses `UserPromptSubmit`; on macOS/Linux, GitLab Duo gets a fail-open user `SessionStart`, while Devin gets `UserPromptSubmit`, `PostCompaction`, and a deduplicated `SessionStart` when Claude does not already provide it. Qoder, GitLab Duo, Devin, and Factory hooks are withheld on Windows without a documented shell/executor contract. Cline's auto-activating file hooks are withheld because their context output is not reliably consumed, CodeBuddy beta hooks are not auto-installed, and Cursor context hooks remain withheld.
+- **Subagent access is explicit** — Claude, Gemini, Kiro, Qwen, CodeBuddy, KiloCode, Mistral Vibe, Qoder, Junie, and Factory get documented graph profiles with the narrowest tool/server filters their schemas support. KiloCode and Vibe enumerate read-only query tools rather than using server wildcards. Cursor, Rovo, Pochi, and Cline use explicit parent handoff where child MCP is unavailable or unsafe; IBM Bob receives no invented hook or agent.
+- **Manual, UI, cloud, or repository-managed (not counted)** — Qodo, Warp MCP, JetBrains AI/ACP, GitHub Copilot coding agent, Jules, CodeRabbit, Replit, BLACKBOX AI, Plandex, and SWE-agent. Warp is counted above for its detected skill installation; its MCP connection remains manual.
