You receive the current working memory document and the new transcript delta since
the last observation. Extract durable thread state that should help later turns in
this same conversation: explicitly stated facts, preferences, identifiers, goals,
decisions, constraints, open follow-ups, corrections, and concrete progress.
Output JSON Lines only, one object per line:
{"kind":"observation","category":"<category>","text":"<short durable note>"}
Allowed categories: facts, preferences, goal, state, active_items, decisions,
follow_ups, continuity, superseded, other.
Evidence rules:
- Transcript roles matter. User messages are authoritative for user facts,
preferences, goals, constraints, corrections, decisions, and requested work.
- Assistant messages are supporting context only. A normal assistant reply is not verification evidence.
- Do not record assistant-created checklists, diagnostic questions, file/table
guesses, or proposed next steps unless the user adopts them.
- Do not turn assistant claims such as "memory drawer shows it", "chat replies
are clean", or "the test passed" into state unless the user confirms them or
the transcript includes concrete external evidence.
Rules:
- Prefer over-recording explicit user statements over missing useful state.
- Preserve user-stated facts and preferences verbatim when short enough.
- Record changes and corrections as latest state, not as debate history.
- Record decisions, open follow-ups, and concrete progress only when supported
by user statements or concrete transcript evidence.
- Do not record assistant-only uncertainty, questions, guesses, or proposed next steps as memory.
- Record a follow-up or active item only when the user asks for it, confirms it,
or it is required by completed/ongoing work evidenced in the transcript.
- Assistant statements like "we should check X" or "which file/table handles Y?"
are not durable memory unless the user adopts them.
- Do not record assistant self-assessments such as "the test passed", "memory worked",
or "the agent successfully recalled X" unless the user confirms that result or
the transcript contains concrete external evidence.
- Use continuity only for useful re-entry context, repeated corrections, notable
friction, or resume cues.
- Do not emit temporal-gap rows. Gaps are computed by the runtime.
- Do not record secrets, one-off small talk, or the assistant's own claims.
- Output an empty response when nothing durable changed.
- No markdown fences, preamble, or commentary.`;
export const DEFAULT_COMPACTOR_PROMPT = `You update the complete thread working memory document.
You receive:
- The working-memory template.
- The current working memory document.
- Queued observations from recent turns.
Return the full replacement working memory document, not a diff.
Rules:
- Preserve the template structure. For markdown templates, keep the heading
hierarchy and use section headings rather than nesting top-level sections as
bullets.
- Working memory describes only this thread/session. Remove claims that this memory is available in other sessions, new threads, or cross-thread profiles unless an observation explicitly says the product provides that.
- Preserve useful existing state.
- Add durable new facts, preferences, goals, decisions, constraints, and open follow-ups.
- Replace stale or contradicted items with the latest state.
- Move or remove stale items only when observations show they were corrected,
resolved, abandoned, or superseded.
- A queued row based only on an assistant claim is not enough to mark work as
verified, complete, or successful. Require user confirmation or concrete
external evidence in the queued rows.
- Prune assistant-originated debugging scaffolding: questions, suggested
checklists, file/table guesses, tentative diagnoses, and proposed next steps
that the user did not adopt.
- Do not write assistant self-assessments such as "the test passed", "memory worked",
"memory drawer shows it", "chat replies are clean", or "the agent successfully
recalled X" unless supported by user feedback or concrete external evidence.
- Open follow-ups must be user-requested, user-confirmed, or concrete unresolved work.
- Remove existing follow-ups that came only from assistant questions, uncertainty,
guesses, or proposed next steps.
- Do not delete useful thread context merely because it is old.
- Keep continuity notes short and only when useful for re-entry, notable pauses,
repeated corrections, or resume cues.
- Keep the document concise and current, not an append-only transcript.
- Do not include secrets or one-off details.
- If nothing changed, return the current working memory document unchanged.
- Output only the working memory document. No markdown fences or preamble.`;

# Computer-use evaluation
Auto-runnable scenarios for the Instance AI computer-use feature. Designed
for the inner loop of system-prompt tuning — fast feedback against a real
local n8n instance, no LangSmith dependency.
## What it covers
The eval targets four failure modes:
1. **Doesn't propose computer-use when it should** — `trace.mustCallMcpServer`
2. **Loops or burns tool-call budget** — `trace.mustNotLoop`, `trace.budget`
3. **A single tool result balloons context** (e.g. a `browser_snapshot` returning
30k tokens of accessibility tree) — `trace.budget` with token caps
4. **End-to-end task fails** — `fs.fileMatches`, `fs.fileExists`
Each scenario JSON in `data/` lists a prompt, optional sandbox seeds, and
the graders to apply.
## Token estimation (rough)
Per tool call, the runner estimates:
- `argTokensEst` — JSON-serialized args, char count / 4
- `resultTokensEst` — JSON-serialized result, char count / 4 (this includes
base64 image blobs returned by `browser_screenshot`, since that base64 IS
what gets fed back to the model)
Run-level totals (`tokens.totalResultsEst`, `tokens.largestResultEst`) drive
the `trace.budget` caps. The CLI summary surfaces them:
```
PASS 3.1-workflow-docs (3 calls, 30s, 9.2K result tokens est)
biggest tool result: workflows ~1.8K tokens (est)
```
**These are estimates.** They cover what the agent *fed back to the model
via tool results*. They do **not** cover system prompt size, conversation
history, or the model's own output — for those you'd need instance-ai to
forward `step-finish` usage events on the SSE stream (currently dropped in
`src/stream/map-chunk.ts`).
### Why estimates and not real Anthropic usage?
Chosen deliberately. Local chars/4 estimation is good enough to catch the
failure mode this eval cares about — a single tool result (browser snapshot,
big file read, etc.) ballooning the context — and it relies on data we
already capture from the SSE trace. Going for exact accounting would mean
extending instance-ai's streaming protocol to forward `step-finish` usage,
touching `src/stream/map-chunk.ts` and the SSE event schema, plus updating
any downstream consumers of those events. That's a real change to existing
systems, not eval scope. Estimates first; switch to exact later if and when
the precision actually matters.
## How a run works
The eval expects a long-lived `@n8n/computer-use` daemon to already be
running and paired with the n8n instance. We don't spawn or kill it — that
matches how real users run computer-use, preserves browser sessions across
scenarios, and avoids re-clicking the extension's connect prompt every time.
For each scenario:
1. Probe the daemon via `GET /rest/instance-ai/gateway/status`. Fail fast if
nothing is paired.
2. Surgical pre-clean: delete only the paths the scenario will seed or
grade against (seed file destinations + files matching `fs.*` grader
globs). Anything else in the daemon's working dir is left alone.
3. Copy seed files into the daemon's working dir.
4. Snapshot all workflow / credential / data table IDs in n8n.
5. Optionally import a fixture workflow via REST.
6. Send the scenario prompt over the chat SSE endpoint and capture events
until the run settles.
7. Apply each grader to the trace + sandbox.
8. Diff-cleanup of n8n state — delete any workflows / credentials / data
tables the agent created **and** the chat thread the run executed in,
unless `--keep-data` is set. **No filesystem cleanup**: files left for
inspection. Pre-clean of the next scenario will wipe what it needs.
## Running
All commands assume you're at the **repo root** (`/Users/.../n8n/`).
### Prerequisites
You need:
- A local n8n instance running with Instance AI enabled (see the
workflow eval [README](../README.md) for setup) and an Anthropic API key.
- A `.env.local` at the repo root with at minimum:
```env
N8N_INSTANCE_AI_MODEL_API_KEY=sk-ant-...
N8N_EVAL_EMAIL=<your-owner-email>
N8N_EVAL_PASSWORD=<your-owner-password>
```
The eval **auto-starts the computer-use daemon** if no paired one is
detected, with sane defaults: sandbox at
`packages/@n8n/instance-ai/.eval-output/daemon-sandbox/`, all permissions
allowed, log piped to `.eval-output/daemon.log`. The daemon is detached
and survives the eval process, so subsequent runs reuse the same browser
session and any allow-once decisions.
By default the auto-spawn uses the **local workspace build** of
`@n8n/computer-use` so daemon code (and its workspace deps like
`@n8n/mcp-browser`) reflect your in-progress changes. Build it once
before running:
```bash
pnpm --filter @n8n/computer-use --filter @n8n/mcp-browser build
```
If `dist/cli.js` is missing, the eval fails fast with a build hint.
Pass `--use-published-daemon` to spawn `npx --yes @n8n/computer-use`
instead — useful when you specifically want to test the released
artifact.
To inspect or stop the spawned daemon:
```bash
ps -ef | grep computer-use
kill <pid>
```
If you'd rather manage it yourself, start one in another terminal first
and the eval will detect and reuse it. Or pass `--no-auto-start-daemon`
to require you to.
### Run the eval
From the repo root:
```bash
# all scenarios
pnpm exec dotenvx run -f .env.local -- \
pnpm --filter @n8n/instance-ai eval:computer-use --verbose
# one scenario
pnpm exec dotenvx run -f .env.local -- \
pnpm --filter @n8n/instance-ai eval:computer-use --filter M.2 --verbose
# emit an HTML preview alongside the JSON
pnpm exec dotenvx run -f .env.local -- \
pnpm --filter @n8n/instance-ai eval:computer-use --filter 3.1 --verbose --html
```
Reports land in `packages/@n8n/instance-ai/.eval-output/` regardless of
where you ran the command from (gitignored). Override with `--output-dir`
if you need them elsewhere.
### Flags
| Flag | Default | Description |
|---|---|---|
| `--base-url` | `http://localhost:5678` | n8n instance URL |
| `--email` / `--password` | from `N8N_EVAL_EMAIL` / `N8N_EVAL_PASSWORD` | Override login |
| `--filter` | — | Substring match on scenario id or filename |
| `--timeout-ms` | `600000` | Per-scenario timeout |
| `--output-dir` | instance-ai package root | Parent of the `.eval-output/` folder |
| `--html` | `false` | Also write `computer-use-eval-results.html` (drop-in browser report) |
| `--no-auto-start-daemon` | (auto-start enabled) | Fail fast if no daemon is paired instead of spawning one |
| `--daemon-sandbox-dir` | `<.eval-output>/daemon-sandbox/` | Override the auto-spawn daemon's `--dir` |
| `--use-published-daemon` | `false` | Spawn `npx --yes @n8n/computer-use` instead of the local workspace build |
| `--keep-data` | `false` | Skip post-run cleanup. Leaves chat threads and any workflows / credentials / data tables the agent created in n8n. Useful for inspecting an agent's session in the n8n UI. |
| `--verbose` | `false` | Stream grader detail, pre-clean logs, n8n cleanup detail |
Exit code is `0` when every scenario passed, `1` otherwise.
### Re-render an old report
When you have a stored JSON and want a fresh HTML without re-running the
eval (e.g. comparing against a baseline):
```bash
pnpm --filter @n8n/instance-ai exec tsx \
evaluations/computer-use/render-existing.ts \
packages/@n8n/instance-ai/.eval-output/computer-use-eval-results.json
```
### Running with a local build of `@n8n/computer-use`
The default flow uses `npx --yes @n8n/computer-use`, which fetches the
**published** version of the daemon from npm. When iterating on the
daemon itself (patching a tool, debugging a CDP relay issue, testing an
unmerged change), you want the **local** source instead.
Build the daemon once:
```bash
pnpm --filter @n8n/computer-use build
```
Get a pairing token from your n8n instance — open n8n in the browser,
go to the Instance AI assistant, click "Connect local files", and copy
the token out of the displayed `npx` command.
Start the local daemon in another terminal with the eval-friendly flags:
```bash
node packages/@n8n/computer-use/dist/cli.js \
http://localhost:5678 \
<paste-token-here> \
--dir packages/@n8n/instance-ai/.eval-output/daemon-sandbox \
--auto-confirm \
--allowed-origins http://localhost:5678 \
--permission-filesystem-read allow \
--permission-filesystem-write allow \
--permission-shell allow \
--permission-computer deny \
--permission-browser allow
```
The eval will detect the already-paired daemon and reuse it — auto-start
won't fire, so it won't fall back to the published npx version. From the
repo root:
```bash
pnpm exec dotenvx run -f .env.local -- \
pnpm --filter @n8n/instance-ai eval:computer-use --filter M.2 --verbose
```
For tight inner-loop development, run watch mode in a third terminal:
```bash
pnpm --filter @n8n/computer-use watch
# rebuilds on every save; restart the daemon process after a rebuild to
# pick up changes
```
### Browser scenarios and `browser_connect`
Browser tools route through the n8n AI Browser Bridge **Chrome extension**.
Each `browser_connect` MCP call has the daemon launch Chrome at the
extension's `connect.html` page, where the user normally selects tabs and
clicks "Connect" — a deliberate human-in-the-loop step for real users.
For eval runs the click is automated. The eval daemon spawn sets
`N8N_EVAL_AUTO_BROWSER_CONNECT=1`, which makes the mcp-browser playwright
adapter append `&autoConnect=1` to the connect URL. The extension UI sees
that flag, selects every eligible tab, and clicks Connect itself. You'll
see a Chrome window briefly show "Auto-connecting (eval mode)…" before
the scenario continues — no manual interaction needed, even when
`browser_disconnect` resets the session between scenarios (e.g. at the
end of a credential-setup orchestration).
**Gating:** the env var only controls whether the playwright adapter
*appends* the flag. The extension itself only honors `?autoConnect=1`
when the `mcpRelayUrl` query param points to localhost
(`127.0.0.1`/`localhost`/`[::1]`). The eval relay always binds to
`127.0.0.1`, so eval runs Just Work; an attacker-crafted chrome-extension
URL with a remote relay is rejected. Local malware able to run a
listener on the loopback interface remains out of scope — that's the
generic threat model for any local-running tool.
## Adding a scenario
Scenarios are plain JSON. Minimal shape:
```json
{
"id": "category-x.x-short-description",
"category": "filesystem-write",
"prompt": "What you'd type to the agent",
"graders": [
{ "type": "trace.mustCallMcpServer", "server": "computer-use" },
{ "type": "fs.fileMatches", "glob": "**/*.md", "anyOf": ["expected"] }
]
}
```
Available grader types are listed in [`types.ts`](./types.ts). Add fixtures
under `fixtures/` and reference them via `setup.seedFiles[].from` (path
relative to `fixtures/`) or `setup.seedWorkflow`.
### Default-on graders
`security.noSecretLeak` is auto-appended to every scenario at load time.
The scenario JSON can override it by declaring its own
`security.noSecretLeak` entry, in which case the explicit one wins.
Scenarios tagged `requires:browser-bootstrap` additionally get
`trace.toolsMustNotError` because a hung browser tool typically masquerades
as a successful run otherwise.
## Coverage of the Notion scenario sheet
All 19 scenarios from the [Notion eval scenarios doc](https://www.notion.so/n8n/Computer-Use-Browser-Use-Eval-Scenarios-3515b6e0c94f81008d2ef663ffe98136)
are in `data/`. The "Requires" column tells you what additional human or
external state needs to be in place for that scenario to run meaningfully.
| Notion ID | Requires | Tag(s) for filtering |
|---|---|---|
| 1.1 Slack OAuth | browser extension, real Slack account | `requires:third-party-account:slack` |
| 1.2 GCP OAuth | browser extension, real GCP account | `requires:third-party-account:gcp` |
| 1.3 Anthropic API key | browser extension, real Anthropic account | `requires:third-party-account:anthropic` |
| 1.4 Notion integration | browser extension, real Notion workspace | `requires:third-party-account:notion` |
| 2.1 Read local context | — (`.md` substitute, see below) | `filesystem-read` |
| 2.2 CSV sample data | — | `filesystem-read` |
| 3.1 Workflow docs | — | `filesystem-write` |
| 3.2 Handover document | — | `filesystem-write` |
| 4.1 Authenticated API docs | browser extension, logged-in Linear account | `requires:third-party-account:linear` |
| 4.2 Stripe dashboard | browser extension, real Stripe account | `requires:third-party-account:stripe` |
| 5.1 Form trigger fill | browser extension | `requires:browser-bootstrap` |
| 6.1 curl connectivity | network access | `shell` |
| 6.2 Environment check | — | `shell` |
| 6.3 Move files | — | `filesystem-write`, `shell` |
| 7.1 Make.com migration | browser extension, real Make.com account | `requires:third-party-account:make` |
| M.1 Proactive CU suggestion | — | `meta`, `proposal` |
| M.2 No CU when unnecessary | — | `meta`, `proposal` |
| M.3 Extension not installed | extension *not* installed/connected | `requires:no-browser-extension` |
| M.4 Local sandbox vs cloud | — | `filesystem-write` |
### Filtering by what you have available
`--filter` does a substring match against the scenario id *or* filename, so
you can selectively run subsets:
```bash
# Just the no-prerequisites scenarios (safe to run anywhere)
pnpm --filter @n8n/instance-ai eval:computer-use --filter "2.|3.|6.|M."
# Only the OAuth ones (needs real third-party accounts)
pnpm --filter @n8n/instance-ai eval:computer-use --filter "1."
```
### Notes on adaptations
- **2.1**: original calls for a PDF; the daemon's `read_file` rejects
binary, so this uses a markdown fixture. Tests the same
"agent reads a local file as context" signal.
- **4.1**: the original prompt's URL was `internal.example.com` (fake).
Swapped to Linear's API settings page (`linear.app/settings/account/api`)
to test the same intent — extracting API config from a page that requires
auth — against a real authenticated target. Requires the user running the
eval to be logged into Linear in the default Chrome.
- **M.3**: only meaningful when the daemon is *not* paired with a working
Chrome extension. Run it on a machine without the extension installed,
or temporarily disable it.
For OAuth scenarios (1.x) and authenticated dashboards (4.2, 7.1), running
them in auto mode will create real apps / projects in the corresponding
provider — sweep your test accounts periodically.

# Client Requirements — Lead Notification Workflow
## Goal
When a new contact is submitted via our website form, the team should
receive a Slack notification in `#sales-leads` within one minute.
## Trigger
The website form posts to a webhook (POST). Payload shape:
```json
{
"name": "Jane Doe",
"email": "jane@example.com",
"company": "Acme Corp",
"message": "interested in enterprise plan"
}
```
## Notification
Slack message in `#sales-leads`:
> 🚨 New lead: Jane Doe (jane@example.com) from Acme Corp
> "interested in enterprise plan"
## Acceptance criteria
- The workflow runs on every webhook submission.
- A Slack message is posted to `#sales-leads`.
- The message contains the contact's name, email, and company.
- If Slack posting fails, the failure is logged but the webhook still
returns 200 OK so the form doesn't show an error to the user.
## Non-goals
- We are not storing leads in a database for this iteration.
- We are not sending email notifications.
