Adds Klaat Code (npm klaatai) as the 22nd supported harness, following the shape of the Devin adapter in #1214.

Klaat Code is a Bun/TypeScript terminal coding agent with a full MCP client (stdio + Streamable HTTP + OAuth 2.1), a lifecycle hooks system, and a skills loader — so it can use all three agentmemory surfaces.

What this adds

MCPagentmemory connect klaatcode merges the standard block into ~/.klaatai/mcp.json. Klaat Code keys its servers under servers rather than mcpServers, so the adapter reuses the same wrapperKey escape hatch Zed already needs for context_servers. Klaat Code supports ${VAR:-default} expansion, so AGENTMEMORY_MCP_BLOCK goes in verbatim.

Hooks--with-hooks installs six native auto-capture hooks into ~/.klaatai/hooks.json.

Klaat Code event script
session_start session-start.mjs
before_message prompt-submit.mjs
before_tool pre-tool-use.mjs
after_tool post-tool-use.mjs
after_message stop.mjs
session_end session-end.mjs

Klaat Code's hooks config is flat — event name straight to a list of entries, where an entry is a bare shell string (v1) or { command, matcher?, timeout? } (v2) — and its event names are snake_case. buildMergedHooks() in codex-hooks.ts assumes the nested Claude shape, so it does not apply here. klaatcode-hooks.ts is a small sibling that keeps the same two guarantees:

  • ${CLAUDE_PLUGIN_ROOT} resolved to the absolute bundled plugin path, so the written file needs no env expansion
  • re-installs strip our previous entries first, so upgrading never duplicates and never touches the user's own hooks (verified for both v1 string and v2 object entries)

Hook payload compat — Klaat Code names the project path project_root and exports KLAATAI_PROJECT_ROOT, neither of which hookCwd() knew about, so observations would have been attached to the wrong project. Both are now in the resolution chain alongside the existing Devin and Claude Code fallbacks. plugin/scripts/*.mjs are rebuilt accordingly (the only diff in those files is this one change).

Deliberately not done

  • No context injection. Klaat Code discards hook stdout except for before_tool block decisions, so there is no return channel. contextPayload() in session-start.ts is untouched — and AGENTMEMORY_INJECT_CONTEXT is default-off since bursting token allocation (re-open) #143 anyway. Recall runs through the MCP tools and the skills.
  • No guideline entry. guidelineTargets() is for hook-less agents; Klaat Code has hooks.
  • No skills wiring needed. Klaat Code already auto-loads ~/.claude/skills and .claude/skills, so npx skills add rohitg00/agentmemory covers all 17 with no extra step.
  • No website grid entry — I don't have a logo asset for Klaat Code. Happy to add one if you'd like to point me at it.

Known limitation

Hooks and MCP are wired into Klaat Code's interactive TUI only — klaatai run (headless), klaatai serve, and ACP sessions are not captured. This is upstream's architecture, not something the adapter can work around. It's called out in the README row and printed after install.

Testing

npm run build && npm run skills:check && npm test — green (1665 passed, 1 skipped).

New test/klaatcode-connect-hooks.test.ts covers placeholder rewriting, the six-event set, the snake_case tool matcher (and that it rejects Claude's Edit/Write/Bash), user-hook preservation in both entry forms, re-install idempotency, project_root / KLAATAI_PROJECT_ROOT resolution, and fail-open when the server is unreachable. test/cli-connect.test.ts bumped to 22 adapters.

Manually verified against a temp HOME:

  • --dry-run --with-hooks reports the merge and writes nothing
  • real install merges servers.agentmemory alongside a pre-existing github server, and appends hooks alongside a pre-existing user after_message string hook and before_tool guard script
  • three consecutive --force re-installs produce a byte-identical hooks.json, 6 agentmemory entries total, no ${CLAUDE_PLUGIN_ROOT} leakage

End-to-end against a running server: feeding Klaat-Code-shaped payloads through session-startpost-tool-usesession-end produced a session with project: klaat-e2e, cwd: /tmp/klaat-e2e, status: completed and the observation captured with channel: tool, detail: edit_file. The MCP shim handshakes at protocol 2025-06-18 and lists all 54 tools.

Pairs with KlaatAI/klaatcode#57, which asks for this integration from the Klaat Code side. A companion PR there adds an agentmemory MCP preset so /mcp enable agentmemory works without leaving the TUI.

Summary by CodeRabbit

  • New Features

    • Added Klaat Code integration through MCP.
    • Added optional hooks for session, message, and tool activity.
    • Added automatic project-root detection and agentmemory skill discovery.
    • Added onboarding support, setup documentation, verification steps, and limitations.
    • Added guideline generation for Klaat Code projects.
    • Captures interactive TUI sessions through supported hooks.
  • Bug Fixes

    • Improved hook reliability across project-directory configurations.
    • Preserved custom hooks during installation and reinstallation.
    • Prevented duplicate bundled hooks during repeated setup.

Adds Klaat Code (KlaatAI/klaatcode) as the 22nd supported harness.

`agentmemory connect klaatcode` merges the MCP entry into
~/.klaatai/mcp.json. Klaat Code keys its servers under `servers`
rather than `mcpServers`, so the adapter reuses the same wrapperKey
escape hatch Zed already needs for `context_servers`.

`--with-hooks` installs six native auto-capture hooks into
~/.klaatai/hooks.json. Klaat Code's hooks config is flat — event name
straight to a list of entries, where an entry is a bare shell string
(v1) or { command, matcher?, timeout? } (v2) — and its event names are
snake_case, so buildMergedHooks() from codex-hooks.ts does not apply.
klaatcode-hooks.ts is a small sibling that keeps the same two
guarantees: ${CLAUDE_PLUGIN_ROOT} is resolved to the absolute bundled
plugin path, and re-installs strip our previous entries first so
upgrading never duplicates and never touches the user's own hooks.

Klaat Code names the project path `project_root` in its hook payload
and exports KLAATAI_PROJECT_ROOT, neither of which hookCwd() knew
about, so the hooks would have attached observations to the wrong
project. Both are now in the resolution chain, alongside the existing
Devin and Claude Code fallbacks.

Context injection is left alone: Klaat Code discards hook stdout
except for before_tool block decisions, and AGENTMEMORY_INJECT_CONTEXT
is default-off anyway. Recall runs through the MCP tools and the 17
skills, which Klaat Code already picks up from .claude/skills without
any extra wiring.

Known limitation, documented in the README row and printed after
install: hooks and MCP are wired into Klaat Code's interactive TUI
only, so `klaatai run` (headless) and ACP sessions are not captured.

Adds Klaat Code guideline generation. Documents MCP configuration, hook installation, verification commands, capture behavior, and skill discovery. Adds Klaat Code to adapter and website listings.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 0789f

This PR adds Klaat Code MCP and hook integration. It is otherwise mergeable, but the new test still uses a CommonJS path global in an ESM codebase, so the test should be corrected or explicitly accepted before merge.

Pull request overview

Adds first-class support for Klaat Code as a new “connect” harness in agentmemory, wiring both MCP configuration and native lifecycle hooks so Klaat Code can participate in agentmemory’s capture surfaces and project attribution.

Changes:

  • Adds a new agentmemory connect klaatcode adapter that merges MCP config under Klaat Code’s servers key and optionally installs native hooks.
  • Introduces a Klaat Code–specific hooks merge engine + bundled hook manifest (hooks.klaatcode.json) with snake_case event/tool matchers.
  • Extends hook project-root resolution to support Klaat Code payload/env conventions, and updates docs + adapter counts accordingly.

Two updates: the logo is in, and I've now verified this end-to-end against a real Klaat Code session rather than synthetic payloads.

Logo

Added website/public/klaatcode.png plus the website/components/Agents.tsx entry and a README grid tile, so the "no logo asset" caveat in the description is resolved.

End-to-end, driven through the actual TUI

Previously I'd only fed Klaat-Code-shaped payloads to the hook scripts directly. I've now wired a temp HOME with agentmemory connect klaatcode --with-hooks, launched the real klaatcode TUI in a sized pty, and had it run a live task (read a file, write a file).

The sidebar showed MCP Servers 1 — agentmemory, and agentmemory captured the session unprompted:

id:      2026-08-17T21-23-52-a6r6      <- Klaat Code's own session id format
project: klaat-tui
cwd:     /private/tmp/klaat-tui        <- resolved from `project_root`
status:  completed                     <- session_end fired
observations: 3

with the observations proving three distinct hook events fired natively:

channel tool type hook
user conversation before_message
tool read_file file_read after_tool
tool write_file file_write after_tool

That covers session_start (session registered), before_message, after_tool, and session_end (status completed) through Klaat Code's real dispatcher — and confirms the project_root fix in _project.ts is what makes the project resolve correctly.

Separately, driving Klaat Code's own MCPManager against the config this adapter writes connects in 12.1s and exposes all 54 tools as mcp__agentmemory__*.

One finding worth flagging

The first connect in a cold environment hit Klaat Code's 30s stdio init timeout while npx -y @agentmemory/mcp downloaded. It recovers on reconnect and affects every npx-based MCP server equally, so nothing to change here — but it's the reason a first-run user might see the server as disconnected before it settles.

I also found and fixed a related bug on the Klaat Code side (KlaatAI/klaatcode#58): native .klaatai/mcp.json entries weren't expanding ${VAR} refs, so a user's custom AGENTMEMORY_URL was silently ignored. Our shim's literal-placeholder guard in rest-proxy.ts:41-46 masked it for the default case, which is exactly what that guard is for.

Full gate still green: npm run build && npm run skills:check && npm test — 1665 passed.

A `||` chain stops at a whitespace-only earlier value, so a blank
DEVIN_PROJECT_DIR would shadow a valid KLAATAI_PROJECT_ROOT and leave
the project unresolved. Select the first non-blank var instead.

Raised by CodeRabbit on rohitg00#1222.

Thanks — went through the three review findings. One was real and is now fixed; two I've skipped with reasons.

1. First non-blank project dir env var — fixed (0178ec9)

Valid catch, and it was mine: extending the || chain to a third variable meant a whitespace-only DEVIN_PROJECT_DIR would short-circuit the chain, fail the subsequent .trim() check, and leave the project unresolved instead of falling through to KLAATAI_PROJECT_ROOT. Now selects the first non-blank var. Regression test added, and the bundled plugin/scripts/*.mjs are rebuilt from it.

2. Remove explanatory comments — skipping

These explain why, not what: which host quirk each branch exists for. The direct sibling of the new file, src/cli/connect/codex-hooks.ts, opens with a ~30-line block comment of exactly this kind documenting the Codex plugin-dispatch workaround, and klaatcode-hooks.ts exists for the same category of reason (Klaat Code's flat, snake_case hook shape). Matching the established house style seemed better than diverging from it in one new file. Happy to trim if you'd rather they go.

3. __dirname in an ESM test — not applicable

Vitest provides __dirname in its module transform, so this works as written; test/devin-connect-hooks.test.ts already uses the identical resolve(__dirname, "..", "plugin") line. The suite passes (1666 tests), which wouldn't be the case if __dirname were undefined here.

Full gate re-run after the fix: npm run build && npm run skills:check && npm test — green, 1666 passed.

Trims the comment blocks in klaatcode.ts, klaatcode-hooks.ts and
_project.ts down to the non-obvious why, per the 'no comments
explaining WHAT' rule in AGENTS.md and CONTRIBUTING.md.

Correcting my previous comment: I was wrong to push back on the comment findings.

I justified keeping them by pointing at codex-hooks.ts as precedent, but I should have checked the written rule first. AGENTS.md:102 says "No code comments explaining WHAT — use clear naming instead", and CONTRIBUTING.md:59 says the same, allowing a comment only where the why is non-obvious. CONTRIBUTING.md:41 also makes CodeRabbit green a merge gate, so leaving those open was blocking the PR on my own preference. Existing code that predates the rule isn't licence to add more.

Trimmed in the latest commit:

  • src/cli/connect/klaatcode.ts — removed the config-layout block entirely; the constant names carry it.
  • src/cli/connect/klaatcode-hooks.ts — 26-line header down to 8, keeping only the two things not visible from the code: why this file exists separately from codex-hooks.ts, and why a ${CLAUDE_PLUGIN_ROOT} token appears for a host that never sets it.
  • src/hooks/_project.ts — dropped both the project_root comment and the first-non-blank rationale.

Full gate re-run: npm run build && npm run skills:check && npm test — green, 1666 passed.

The __dirname finding I'm still leaving as-is: Vitest provides it in its transform, test/devin-connect-hooks.test.ts uses the identical line, and the suite passes. Happy to switch it to fileURLToPath anyway if you'd prefer consistency over precedent — just say the word.

guidelineTargets deliberately omits Claude Code and Codex because their
hooks already auto-capture, and I originally skipped Klaat Code on the
same reasoning. That was wrong: Klaat Code discards hook stdout except
for before_tool block decisions, so unlike those two it has no path for
injecting recalled context. Capture worked, but nothing ever prompted
the model to call memory_recall, which left recall — the actual point
of the integration — inert.

Targets ~/.klaatai/rules.md, which system-prompt.ts reads globally
before the per-project rules, using the same marked-block format as the
other shared instruction files.

Verified end to end against a real Klaat Code session: with the
guideline in place a fresh session calls memory_recall and
memory_smart_search unprompted and gets back a fact saved by an earlier
session.

I went back and tested the thing that actually matters — does a memory saved in one Klaat Code session come back in the next — rather than just proving hooks fire. It surfaced a gap in this PR, now fixed, and one limitation worth your call.

The gap: recall was inert

I originally skipped guidelineTargets() for Klaat Code, reasoning that it has hooks so it's in the same bucket as Claude Code and Codex. That was wrong. Those two can inject recalled context back through their hooks; Klaat Code discards hook stdout except for before_tool block decisions. So capture worked fine, but nothing ever told the model to call memory_recall — the half users actually notice was doing nothing.

Fixed by adding a klaatcode target writing to ~/.klaatai/rules.md, which system-prompt.ts loads globally ahead of per-project rules, in the same marked-block format as the other shared instruction files.

Verified end to end, in the real TUI

Session 1 — model calls mcp__agentmemory__memory_save:

⏺ Mcp:agentmemory memory_save
  ⎿ {"memory":{"concepts":["billing","stripe","payment-intents","checkout","split-payouts"], …

Session 2 — brand new session, same repo, only the guideline in context:

⏺ Mcp:agentmemory memory_recall         "billing integration change"
⏺ Mcp:agentmemory memory_smart_search   "billing integration change reason"
  ⎿ "Moved billing from Stripe Checkout to Stripe Payment Intents …"  score 1

Unprompted recall of a fact from a previous session. That's the feature working. Also confirms the 54 tools connect in the real TUI (● agentmemory 54t) and that Klaat Code picks up the skills — it read skills/remember/SKILL.md off ~/.agents/skills with no extra wiring.

The limitation — your call on whether it blocks

Project scoping does not survive the MCP path, and this isn't Klaat Code-specific. The hook path resolves correctly (server logged {"project":"memproj"}), but memory_save's schema says the project "must match the value used when the session was started" while nothing in the MCP surface tells the model what that value is. resolveProject is only wired into src/hooks/*. In my run the model filled the field with a plausible-looking but wrong slug, and the memory was filed under an unrelated project.

Recall still found it — because the model doesn't scope its queries either, so search runs unscoped. Correct behaviour today, by accident. On a machine with many projects it would surface as cross-project bleed.

I've left it alone here because a fix belongs in the MCP layer for every host, not in one adapter — but say the word and I'll take it in a follow-up.

Gate green after the change: npm run build && npm run skills:check && npm test — 1667 passed.

One environmental note: roughly half my TUI runs died on KlaatAI is temporarily unavailable mid-request. Unrelated to agentmemory — a plain headless prompt hit the same API fine.
