Also: `sessionKey` can only come from the + JSON body's `sessionKey` field — a sender that can't change its payload + (fixed-shape hooks) gets a new one-shot session per request, and the + response (`{...result}`) carries no `sessionId` for the caller to + correlate (contrast `httpChannel`, which returns `sessionId`). +- **Fix:** warn (or document loudly) when mounted without `auth`/`secret`; + add a `sessionKey?: (body, req) => string` option and `sessionId` in the + response. + +### F13: Discord signature check has no timestamp freshness — captured requests replay indefinitely + +- **Evidence:** `checkSignature` (`discordChannel.ts:82-90`) verifies + Ed25519 over `timestamp + body` but never checks the timestamp's age — + unlike Slack's 5-minute window (`slackSignature.ts:31-33`).

The README (`README.md:53`) and `docs/installation.md` both tell new users to run `npm install @lousho/build-ai-agent ai@^7.0.0 zod` — that resolves `latest` → **alpha.0**, an API generation that predates the `createAgent()`-centric docs (there is even a `migrating-to-create-agent.md` doc for APIs newer than that build). Snippets like `createAgent({ model })`, `agent.approvals.resolve`, `@lousho/build-ai-agent/testing` may not exist or behave differently there. +- **Why it matters:** the documented happy path installs a different product than the docs describe. Every other finding in this file is downstream noise compared to this. +- **Fix:** `npm dist-tag add @lousho/build-ai-agent@1.0.0-alpha.19 latest` (or repoint docs to `@lousho/build-ai-agent@alpha`), and add a release step/CI check asserting `latest` is the newest published version.

Looks unpolished exactly where a MCP-curious evaluator lands. +- **Fix:** detect `fs.statSync(p).isDirectory()` (reuse `detectTarget` or a `SPEC_EXT` check) and throw `LOUSHO_CONFIG_INVALID` ("agent spec file required; agent directories aren't supported by `lousho mcp`") — or better, accept agent dirs like the sibling commands do. + +### F3 — `lousho add` writes into any directory — in an `init` project it drops a dead tool file nothing loads + +- **Severity:** high +- **Persona:** AI engineer +- **Evidence:** `src/cli/add.ts:175-181` validates only that `--dir` exists and is a directory. Repro: `lousho init my-agent` (scaffolds `src/agent.ts`, no `agent.json`), then `lousho add open-meteo-weather --yes --allow network` from inside it → succeeds, writes `tools/open-meteo-weather.ts` + `lousho-registry.json` at project root. The scaffolded agent (`src/agent.ts`: `const tools = [currentTime]`) never reads `tools/`, so the install is a no-op the user cannot detect — `npm run dev` still has one tool. +- **Why it matters:** the two headline onboarding flows (`init` then `add`) are structurally incompatible and nothing says so. A new user concludes "`add` is broken" or "the agent ignores tools". +- **Fix:** when `--dir` contains no `agent.json`/`agent.yaml`/`agent.ts`, either refuse with a hint ("this isn't an agent directory — `lousho init` projects import tools in `src/agent.ts`; import it there, or create an agent dir") or at minimum warn post-write that nothing loads the file automatically.

Biggest contributors: `apps/agent-forge/dist-server/index.cjs` 1.4 MB + client bundle ~1.2 MB, `llms-full.txt` 978 kB, `src/` 405 files (kept deliberately for sourcemap `sources`, `tsup.config.ts:82-85`), `dist/` 503 files incl. maps. `files` (`package.json:117-140`) also ships all `docs/*.md` and `CHANGELOG.md` (268 kB). +- **Why it matters:** every `npm install` — including CI and Docker images — downloads a bundled React dashboard, a megabyte of docs-as-text, and the full TS source. Competitors' agent SDKs install a fraction of this. It also makes `create-lousho-agent` (which hard-depends on the SDK, `packages/create-lousho-agent/package.json`) a 19 MB scaffold. +- **Fix:** consider a separate `@lousho/agent-forge` / `lousho-studio` package (or download-on-first-`studio`), and move `llms-full.txt` to docs-site/lazy-fetch (keep `llms.txt` small index). If `src/` stays for sourcemaps, say so in `docs/installation.md` so the size is a stated trade-off, not a surprise. + +### F5 — Examples import `../../src` instead of `@lousho/build-ai-agent`; the audit's own rules forbid it + +- **Severity:** medium +- **Persona:** AI engineer +- **Evidence:** 48 files under `examples/` import `from '../../src'` / `../../src/testing` (e.g. `examples/support-bot/index.ts`, `examples/data-analyst/index.ts`); only the kit tests use `@lousho/build-ai-agent/testing` and a few examples have `package.json` stubs. `audit/AUDIT_BRIEF.md:28` explicitly instructs consumer harnesses: "Import only from `@lousho/build-ai-agent` (and its subpaths) — never from `../../src`." +- **Why it matters:** copying an example into a real project fails at the first import line; examples also can't validate the *published* surface (exactly the class of drift this audit hunts). Users learn a path style that only exists inside this repo. +- **Fix:** point example `package.json`s at `file:../..` (or the published spec) and rewrite imports to `@lousho/build-ai-agent` and `@lousho/build-ai-agent/testing`; keep a CI job type-checking them against the packed tarball. + +### F6 — README's "flagship" example and two others teach the legacy `AgentBuilder`/`AgentExecutor` API + +- **Severity:** medium +- **Persona:** AI engineer / PM +- **Evidence:** 9 files in 3 examples use `AgentBuilder`, `AgentExecutor`, `ToolRegistry`: `examples/ops-pipeline/{index,monitor,fixer,slackInteractions,pipeline.eval}.ts` (README:276 calls ops-pipeline "Flagship"), `examples/tracing/{run-console,run-otel,weather-scenario}.ts`, `examples/openrouter/index.ts`. `weather-scenario.ts:8` even does `import { tool } from 'ai'` — the Vercel helper, not `defineTool`. Meanwhile README and `docs/migrating-to-create-agent.md` position `createAgent()` as *the* API and executor pieces as "lower-level". +- **Why it matters:** an evaluator following README → "flagship" example meets an API the docs tell them to migrate *away* from. It reads as two products. +- **Fix:** port ops-pipeline and tracing to `createAgent` (or clearly retitle them "advanced/executor API examples"), and replace `tool` from `ai` with `defineTool`. + +### F7 — `lousho build` leaks raw esbuild errors where `lousho dev` gives a coded, actionable one + +- **Severity:** medium +- **Persona:** Software engineer / Designer (error quality) +- **Evidence:** same agent dir, missing `zod`: `lousho dev` → `LOUSHO_AGENT_DIR_INVALID` with "npm install zod" guidance; `lousho build ./adir --target=node-server` → raw `X [ERROR] Could not resolve "zod"` + `ESM Build failed` + esbuild's own hint ("mark the path as external" — wrong advice here), and it leaves a half-written `out/` (scaffold files present, `dist/` missing). `src/deploy/adapters/node-server.ts:291-317` calls `loadTsup().build` with no error translation (`LOUSHO_BUILD_VERBOSE` only controls noise). +- **Why it matters:** inconsistent error quality across commands; esbuild's suggestion actively misleads. +- **Fix:** catch bundling failures and map unresolved-module errors to the same "install X in the agent dir's project" guidance `loadAgentDir` produces; consider cleaning `out/` on failure or warning that it's partial. + +### F8 — `lousho chat` / `lousho acp` report path errors as "`lousho dev:`" + +- **Severity:** medium +- **Persona:** Designer (error correctness) +- **Evidence:** `lousho chat ./missing-dir` prints `lousho dev: './missing-dir' does not exist.` `src/cli/devReload.ts:81` hard-codes `lousho dev:` inside `detectTarget`, which `chat.ts:62` and `acp.ts` share.

Honestly: 'lousho' is a weak name (hard to say, spell, or recall; auto-corrects to "lousy"/"Lou, sho?"); flagging per the brief, but at minimum unify `studio`/Agent Forge. +- **Fix:** pick one public name for the dashboard (either `lousho forge`/`lousho studio` or "Agent Forge", used everywhere); delete or restore `packages/create-loushy-agent`; consider a short import alias (`lousho`) before 1.0 freezes the name. + +### F12 — `create-lousho-agent@latest` (0.1.1) lags `alpha` (0.1.2-alpha.4) and drags the whole SDK in to scaffold + +- **Severity:** low +- **Persona:** SWE / AI engineer +- **Evidence:** `npm view create-lousho-agent dist-tags` → `latest: 0.1.1`; its dep `@lousho/build-ai-agent@^1.0.0-alpha.8` resolves the newest alpha at install (so the *generated* project is fine), but the scaffolder itself is stale and installs ~19 MB + peers to print a wizard. +- **Fix:** same dist-tag hygiene as F1; consider `--tag alpha` on `npm create` docs until 1.0. + +### F13 — `engines: node >=22.19.0` is a patch-level floor that excludes Node 20 and almost all of 22.x + +- **Severity:** low +- **Persona:** Software engineer (install friction) +- **Evidence:** `package.json:224-226`; `docs/installation.md` justifies it via `undici@8` (and native type-stripping for `lousho dev agent.ts` on ≥22.18 helps explain the floor). Any evaluator on Node 20 LTS or 22.0–22.18 gets an `EBENGINE` warning on every install. +- **Fix:** fine to keep, but surface it earlier — the README does say "Requires Node.js 22.19"; consider a sentence on *why* (native `.ts` import for `lousho dev/chat/acp`) since it reads arbitrary. + +### F14 — Three vocabularies for the same fields: spec `prompt`/`provider.{type,model}` vs agent dir `instructions`/`model` vs `createAgent` `instructions`(+`prompt`) + +- **Severity:** low +- **Persona:** Designer (API consistency) +- **Evidence:** `spec.yaml` `{name, prompt, provider:{type,model}}` (`src/spec/schema.ts:315-316`, `150-151`); `agent.json` `{model}` + `instructions.md`; `createAgent({ model, instructions })` where `prompt` is only an alias (`docs/quick-start.md` §1). Guessing `model:` + `instructions:` in a spec fails validation (good error, but a needless trip-wire: "missing required field 'prompt'; 'provider': Required"). +- **Fix:** accept the `createAgent` spellings in the spec schema as aliases, or add a table in `docs/configuration.md` mapping the three vocabularies. + +### F15 — `cp .env.example .env` is Linux/macOS-only advice in the README, generated README and quick-start + +- **Severity:** low +- **Persona:** Designer (polish) +- **Evidence:** `README.md:45`, `docs/quick-start.md` §"Start a new project", and the generated project `README` (`src/cli/init` templates) all say `cp .env.example .env` — fails in Windows `cmd`/PowerShell (`copy`/`Copy-Item`).

Create it, or pass --dir`. For a *kit* (which creates a whole agent dir) requiring the parent to pre-exist is a papercut — `mkdir my-agent` is missing from the docs flow. +- **Fix:** either create the dir for kit installs (`--dir` absent target → offer to create), or add `mkdir my-agent` / a one-liner to the README and `docs/registry.md`. + +### F19 — `lousho init --yes` scaffolds an OpenAI project even with no API key; first `npm run dev` then dead-ends + +- **Severity:** low +- **Persona:** AI engineer +- **Evidence:** `lousho init my-agent --yes` in a keyless env → "Creating minimal openai agent…". `--provider` defaults "detected from your API key env var, else openai" (`init --help`).

An empty result returns `{loaded: [], more: N}` — the model + reads "no such tool" and either fishes with synonyms or gives up. +- Why it makes us look bad: the deferred-tools story depends on the model finding the tool; + pure keyword search fails on synonyms — the exact thing embeddings solve. There is a `search` + escape hatch, but no built-in embedder-backed ranker despite the SDK shipping + `EmbeddingProvider`/`hashEmbedder` infra. +- Suggested fix: ship an optional embedder-backed `toolSearch.search` preset (cosine over + name+description embeddings, computed once), or at least tokenize symmetrically + (character n-gram fallback when keyword score is 0). + +### F14: `compaction.start`/`compaction.done` fire on every step even when nothing compacts +- Severity: low +- Persona: AI engineer (observability DX) +- Evidence: `compaction.ts:406-446` — both events are emitted unconditionally once the request + is over threshold, then `if (result.messages === messages && !error) return` skips only the + mutation/`onCompaction`. A run stuck over threshold with nothing prunable (e.g. F5's small + window, or a transcript that's all user text) emits a `compaction.start`+`done` pair per step + with identical token counts — indistinguishable in a stream from real compaction. +- Suggested fix: emit `compaction.start` lazily (after the strategy reports a change), or add a + `noop`/`unchanged` flag to `compaction.done`; consider a "gave up" marker after repeated + no-ops. + +### F15: `remember_<name>` description claims memory is "recalled in later conversations" — false for `scope: 'session'` +- Severity: low +- Persona: Designer +- Evidence: `withMemory.ts:36` hardcodes `"so it is recalled in later conversations"`.

It checks only +that the loaded checkpoint is `in-progress` — nothing verifies the checkpoint belongs to the run +that failed. The next `send()` hits `resumePending` +(`AgentSession.ts:1032-1040`): `failed.retryable === false` → `LOUSHO_SESSION_TURN_FAILED`, forever — +the victim run's only way out is `discardPending()` (losing its work) or an explicit `resume()`. + +**Why it matters.** A stale/zombie run (the exact scenario run leases exist for) can permanently +poison the live run's durable state with a failure the live run never had. Unfenced writes are the +bug class leases were added to prevent; this writer was left out. + +- **AI engineer:** every checkpoint writer must go through the lease (or compare-and-store on a run identity field); `recordFailure` is the one path that skips it. +- **PM:** rare but catastrophic for durable sessions — a healthy long-running turn becomes unrecoverable because an unrelated stalled attempt died. +- **Software engineer:** minimal fix — load-and-save under the run's lease (`saveIfLeased`), or stamp `runId` on checkpoints and refuse the write on mismatch. +- **Designer:** n/a — invisible corruption; only shows as "this session can never continue" to the end user. + +## 3.

The gap is small in wall-clock terms but +deterministic under any store latency — and a crashed process between the two writes leaves the +marker absent *permanently* while the awaiting checkpoint persists, so a post-restart durable send +is admitted beside a pending approval. + +- **AI engineer:** the marker and the pause checkpoint must be one write (or the guard must also treat an awaiting-approval turn checkpoint as paused); two durable writes for one logical transition is the bug. +- **PM:** approval-paused sessions can silently double-execute work — for gated tools that's "the human said wait, the system ran anyway" in a narrow but real window, wider after a crash. +- **Software engineer:** `pausedSessionTurn` could also scan `<id>.turn-*` for `status === 'awaiting-approval'` instead of trusting the pointer — defense in depth for the crash window. +- **Designer:** "waiting for approval" must be a state the moment the run pauses, not a second I/O later. + +## 4.
