Subject: [PATCH 2/5] feat(mcp): steer agents to explore-first; fix
 Kotlin/Swift test detection (#191)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

* feat(mcp): steer agents to explore-first; fix Kotlin/Swift test detection

Two changes from diagnosing why Claude Code's Explore agent wasn't using
codegraph_explore on a benchmark run (37 calls / ~90k tokens via
search+Read+grep, vs a general-purpose agent that led with explore: 13
calls / ~55k tokens for the same question).

1. Tool guidance reframed across server-instructions.ts,
   instructions-template.ts, and .cursor/rules/codegraph.mdc (+ the
   explore/search tool descriptions): codegraph_explore is the workhorse
   for understanding/architecture/"how does X work" questions. Seed it with
   the key symbol names (a quick search/context first if the question names
   nothing concrete), read its output, and fill gaps with node/Read —
   instead of searching then Reading each file. The old "search first to
   find names, then explore" wording was short-circuiting: agents searched,
   got file:line locations, and Read them, never reaching explore.

2. isTestFile now recognizes Kotlin (*Test.kt, jvmTest/commonTest/
   androidTest source sets), Swift (*Tests.swift), and other camelCase test
   conventions, so test code is deprioritized in explore/context ranking.
   Previously only Java/JS/Python were known, letting tests dominate
   Kotlin/Swift exploration (OkHttp "trace a request" went from 8/9 test
   files to surfacing Call.kt/OkHttpClient.kt/Request.kt/Response.kt).
   Capital-led matching keeps latest.kt/manifest.kt unflagged.

An IDF common-term down-weighting was prototyped for the cold-query case
but dropped — it was a measured no-op (the "common" terms weren't actually
common in the test indexes); the test-detection gap was the real cause.

* chore(agent-eval): add agent-behavior eval harness for codegraph MCP usage

Tooling to measure how a Claude Code agent actually uses the codegraph
MCP tools on a real repo — does it lead with codegraph_explore, how many
Read/Grep follow-ups, token cost — for validating tool-guidance changes
(server-instructions, tool descriptions) against real agent behavior.

- itrun.sh drives the real interactive TUI via tmux (the faithful
  Explore path). Hardened for unattended runs: type-and-verify prompt
  delivery (the ❯ glyph is drawn ~6s before the input accepts keys),
  auto-accepts the "trust this folder" dialog, busy-detection keys on
  the universal "(Ns · …)" spinner so the pre-stream thinking phase
  counts as busy, and fails loudly instead of capturing an empty pane.
- parse-session.mjs reports the tool breakdown + token accounting
  (gen / fresh-in / cached-in / billable) from the session and subagent
  logs, consistent across main-thread and subagent runs; counts
  main-thread Bash in the grep verdict.
- run-agent.sh / parse-run.mjs are the headless stream-json complement
  (exact per-tool tokens/cost via claude -p).
- run-interactive-test.md documents how to run it and how completion is
  detected.

 ### Rules of thumb
 
+- **`codegraph_explore` is the workhorse for understanding questions** ("how does X work", "trace…", "explain the Y system"). Feed it the key symbol/file names and read its output (line-numbered source from many files in one call). If the question names nothing concrete, do one quick `codegraph_search`/`codegraph_context` to surface the names, then explore with them. Fill gaps with `codegraph_node`/Read — don't grep-and-read your way through; that's the loop explore replaces.
+- **Delegating exploration to a subagent?** Tell it to call `codegraph_explore` first and trust the result. A generic "explore"-style agent defaults to grep+Read and treats codegraph as just a search index, throwing away the token savings.
 - **Trust codegraph results.** They come from a full AST parse. Do NOT re-verify them with grep — that's slower, less accurate, and wastes context.
 - **Don't grep first** when looking up a symbol by name. `codegraph_search` is faster and returns kind + location + signature in one call.
-- **Don't chain `codegraph_search` + `codegraph_node`** when you just want context — `codegraph_context` is one call.
-- **`codegraph_explore` is the heavy hitter** for unfamiliar areas — it returns full source from all relevant files in one call, but is token-heavy. If your harness supports parallel subagents (e.g., Claude Code's Task tool), spawn one for explore-class questions to keep main session context clean.
 - **Index lag**: the file watcher debounces ~500ms behind writes; don't re-query immediately after editing a file in the same turn.

+# Running the agent-behavior test (how agents actually use codegraph)
+
+This explains how to measure **how a Claude Code agent uses the codegraph MCP
+tools** on a real repo — which tools it calls (does it lead with
+`codegraph_explore`?), how many follow-up `Read`/`Grep`s it does, and the token
+cost. Use it when changing tool guidance (`server-instructions.ts`,
+`instructions-template.ts`, tool descriptions) or retrieval, to verify the
+change actually shifts agent behavior.
+
+Scripts live in `scripts/agent-eval/`.
+
+## Why two harnesses (read this first)
+
+| | Interactive (`itrun.sh`) | Headless (`run-agent.sh`) |
+|---|---|---|
+| Drives | the real TUI via tmux | `claude -p` print mode |
+| Subagent it picks | **Explore** (matches real UX) | general-purpose (diverges) |
+| Metrics | tool breakdown (from session logs) + `Done(…)` token summary | exact per-tool calls + tokens/cost (stream-json) |
+| Cost | Claude Max subscription | API $ (`total_cost_usd`) |
+
+**Headless `claude -p` does NOT reproduce what users see** — it silently picks
+the general-purpose subagent, while interactive sessions delegate to the
+read-first **Explore** subagent. So for "what does my session actually do," use
+the interactive harness. For a clean per-tool/token breakdown in one shot, use
+headless (and ask for the Explore subagent in the prompt if you want that path).
+
+## Prerequisites
+
+- **tmux 3.0+**
+- A logged-in `claude` CLI (Claude Max or API).
+- codegraph configured as an MCP server (`claude mcp list` shows `codegraph`).
+  The interactive harness uses your global config, so it runs whatever
+  `codegraph` resolves to — point that at your dev build (`npm link` / the
+  symlinked global) to test local changes.
+- A target repo, cloned and indexed:
+  ```bash
+  git clone --depth 1 https://github.com/square/okhttp /tmp/corpus/okhttp
+  cd /tmp/corpus/okhttp && codegraph init -i
+  ```
+  Good scale spread for a sweep: Alamofire (~100 files), Excalidraw (~600),
+  OkHttp (~640), VS Code (~10k).
+
+## Interactive test (the faithful one)
+
+```bash
+scripts/agent-eval/itrun.sh <repo-path> <label> "<question>"
+```
+
+Example:
+```bash
+scripts/agent-eval/itrun.sh /tmp/corpus/vscode vscode \
+  "How does the extension host communicate with the main process?"
+```
+
+It opens `claude` in a tmux session, types the question, waits for the agent to
+finish, then prints:
+- the `Done (N tool uses · Xk tokens · Ym)` subagent summary (from the pane),
+- the `Context Xk/1.0M` main-session size,
+- a **tool breakdown** parsed from the session logs (main + subagents), ending
+  in a `VERDICT: codegraph_explore used Nx | Read N | Grep/Bash N` line.
+
+### Startup robustness (so unattended runs don't silently no-op)
+
+Two things bite an unattended driver before the prompt even runs:
+- **The `❯` glyph is drawn ~6s before the input accepts keystrokes.** Waiting
+  for `❯` is necessary but not sufficient. The harness sends the prompt, then
+  **verifies a chunk of it actually landed in the input box**, retrying until it
+  does — so it can't type into a not-yet-live input and submit nothing.
+- **First time claude opens a repo it shows "Is this a project you trust?"**
+  (which also contains `❯`). The harness detects that dialog and presses Enter
+  to accept it before typing.
+
+If the prompt never lands or work never starts, the harness now **fails loudly**
+(non-zero exit) instead of capturing an empty pane and reporting a bogus run.
+
+### How completion is detected (the tricky part)
+
+Claude's TUI redraws in place, so you can't just wait for output to stop. The
+harness polls `tmux capture-pane` and treats the pane as **busy** when it shows
+the spinner's elapsed-time-in-parens — `(8s · …)` / `(1m 3s · …)`, matched by
+`\(([0-9]+m )?[0-9]+s ·`. That's the *universal* working signal: it shows during
+the pre-stream **thinking** phase (`(8s · thinking with max effort)`, which has
+no token arrow yet) *and* during streaming. The `↓ N`/`↑ N` token arrow,
+`esc to interrupt`, and `Initializing…` are OR'd in as belt-and-braces (some TUI
+versions show one but not the others). It declares **idle** when the `❯` prompt
+is present and not busy for 10 consecutive polls (~5s, long enough to ride out
+mid-conversation thinking gaps that briefly drop the spinner). (Technique
+adapted from devpit's `WaitForIdle`.)
+
+### Where the breakdown comes from
+
+`parse-session.mjs` reads the newest session log under
+`~/.claude/projects/<escaped-cwd>/<session>.jsonl` and its subagent transcripts
+under `<session>/subagents/*.jsonl`. The **subagent** file is where the real
+tool calls are — the main log only shows the `Agent` delegation. You can run it
+standalone:
+```bash
+node scripts/agent-eval/parse-session.mjs /tmp/corpus/vscode
+```
+
+## Headless test (clean tokens, forceable Explore path)
+
+```bash
+scripts/agent-eval/run-agent.sh <repo-path> <label> "<question>"
+```
+Writes stream-json and prints the tool sequence + exact tokens/cost. To
+reproduce the Explore-subagent path headlessly, ask for it:
+`"Use an Explore subagent to investigate, then answer: …"`.
+
+## Running a sweep
+
+Single runs vary a lot (the VS Code question has ranged 26–37 tool uses /
+88–105k tokens across runs). For a real signal, run N≥3 and take the median:
+```bash
+for i in 1 2 3; do
+  scripts/agent-eval/itrun.sh /tmp/corpus/vscode "vscode-$i" "<question>"
+done
+```
+
+## What "good" looks like
+
+After the explore-first guidance (PR #191), an understanding question should
+show the agent **leading with `codegraph_explore`** and using `search`/`node`
+to fill gaps — not a wall of `Read`/`Grep`. Example faithful run:
+`VERDICT: codegraph_explore used 3x | Read 8 | Grep/Bash 1`. If `explore` is 0
+and `Read`/`Grep` dominate, the guidance regressed.
+
+## Output artifacts
+
+Transcripts and logs go to `$AGENT_EVAL_OUT` (default `/tmp/agent-eval/`):
+`itrun-<label>.txt` (pane capture), `run-<label>.jsonl` (headless stream-json).

 ### Rules of thumb
 
+- **\`codegraph_explore\` is the workhorse for understanding questions** ("how does X work", "trace…", "explain the Y system"). Feed it the key symbol/file names and read its output (line-numbered source from many files in one call). If the question names nothing concrete, do one quick \`codegraph_search\`/\`codegraph_context\` to surface the names, then explore with them. Fill gaps with \`codegraph_node\`/Read — don't grep-and-read your way through; that's the loop explore replaces.
+- **Delegating exploration to a subagent?** Tell it to call \`codegraph_explore\` first and trust the result. A generic "explore"-style agent defaults to grep+Read and treats codegraph as just a search index, throwing away the token savings.
 - **Trust codegraph results.** They come from a full AST parse. Do NOT re-verify them with grep — that's slower, less accurate, and wastes context.
 - **Don't grep first** when looking up a symbol by name. \`codegraph_search\` is faster and returns kind + location + signature in one call.
-- **Don't chain \`codegraph_search\` + \`codegraph_node\`** when you just want context — \`codegraph_context\` is one call.
-- **\`codegraph_explore\` is the heavy hitter** for unfamiliar areas — it returns full source from all relevant files in one call, but is token-heavy. If your harness supports parallel subagents (e.g., Claude Code's Task tool), spawn one for explore-class questions to keep main session context clean.
 - **Index lag**: the file watcher debounces ~500ms behind writes; don't re-query immediately after editing a file in the same turn.

 ## Tool selection by intent
 
-- **"What is the symbol named X?"** → \`codegraph_search\`
-- **"What's the deal with this task / feature / area?"** → \`codegraph_context\` (PRIMARY — composes search + node + callers + callees in one call)
+- **"How does X work? / trace X end to end / explain the Y system / architecture?"** → \`codegraph_explore\` (PRIMARY for understanding — seed it with the key symbol names, read its output, don't grep+Read your way there)
+- **"What is the symbol named X? / where is X defined?"** → \`codegraph_search\` (pinpoint lookups)
+- **"What's the deal with this task / feature / area?"** → \`codegraph_context\` (lighter composed view of search + node + callers + callees)
 - **"What calls this?"** → \`codegraph_callers\`
 - **"What does this call?"** → \`codegraph_callees\`
 - **"What would changing this break?"** → \`codegraph_impact\`
 - **"Show me this symbol's source / signature / docstring."** → \`codegraph_node\`
-- **"Survey an unfamiliar topic / pattern / module."** → \`codegraph_explore\` (heavier; deep dive)
 - **"What's in directory X?"** → \`codegraph_files\`
 - **"Is the index ready / what's its size?"** → \`codegraph_status\`
 
 ## Common chains
 
-- **Onboarding**: \`codegraph_context\` first. If still unclear, \`codegraph_explore\` for breadth, then \`codegraph_node\` on specific symbols.
+- **Understanding / onboarding**: feed \`codegraph_explore\` the key symbol/file names and read its output (line-numbered source from many files in one call). If the question names nothing concrete, do ONE quick \`codegraph_search\` / \`codegraph_context\` to surface the names, then explore with them. Fill remaining gaps with \`codegraph_node\` / Read — don't drop back to grep+Read for the whole topic.
 - **Refactor planning**: \`codegraph_search\` → \`codegraph_callers\` → \`codegraph_impact\`. The blast-radius answer comes from impact, not from walking callers manually.
 - **Debugging a regression**: \`codegraph_callers\` of the suspected symbol; widen with \`codegraph_impact\` if an unexpected call appears.
 
 ## Anti-patterns
 
+- **Don't search-then-Read your way through an understanding question** — feed the names you find into \`codegraph_explore\` instead of Reading the files one by one; it does that whole loop in one call and returns line numbers you can cite directly.
 - **Don't grep first** when looking up a symbol by name — \`codegraph_search\` is faster and returns kind + location + signature.
-- **Don't chain \`codegraph_search\` + \`codegraph_node\`** when you just want context — \`codegraph_context\` is one round-trip.
-- **Don't use \`codegraph_explore\` for narrow questions** — it's a multi-call deep dive, expensive in tokens. Save it for genuine "I'm new here" surveys.
+- **Don't reach for \`codegraph_explore\` on a pinpoint "where is X defined" lookup** — \`codegraph_search\` is one cheap call.
 - **Don't query the index immediately after editing a file** — the watcher needs ~500ms to debounce + sync. Wait for the next turn.
