Follow-up to #346, as discussed in #347: when a tool's describe_fn names the actual action, the card's heading and badge use the engine's risk_label instead of the tool-name rules.

  • A browser click's describe_fn reads the clicked element, so clicking an ordinary button now reads as a click, while clicking "Place order" still reads as a purchase.
  • The engine always fills risk_label, so the card only trusts it when it differs from the generic per-risk fallback in sentient/tools/base.py (Looks something up / Changes something / Sends / Runs code): that means a describe_fn actually ran. Otherwise the fix(desktop): name approval card from tool name and risk, never argument content #346 tool-name rules keep naming the action, so email tools and the rest read exactly as before.
  • Unknown future labels are shown as-is with a plain verb ("Sentient wants to do this") and the risk's tone, so new engine labels never break the card.
  • The trash-kind preview check (Previews, undo windows and reversible defaults #142) still runs first.

Checks: 72/72 desktop unit tests green (7 new for the label precedence), npm run typecheck clean. No engine or API contract changes (risk_label was already in docs/API.md).

Fixes #347

Summary by CodeRabbit

  • Bug Fixes
    • Browser approval cards use the clicked element’s label and action category to distinguish ordinary clicks, feedback submissions, and purchases.
    • Approval cards retain tool-specific wording and use engine-provided labels to clarify generic descriptions when available.
    • Trash previews follow consistent wording rules, with execution actions handled separately.
    • Cards display action-appropriate icons, with a fallback icon for unrecognized risk labels.

📝 Walkthrough

The approval card uses engine risk labels and tool-based rules to determine action wording and tone. Browser tools use nonempty engine labels directly. Other tools retain specific tool-based wording and use engine labels to refine generic wording. The card also maps engine labels to icons.

Change: Bug fix · Severity of issue fixed: Medium

Suggested reviewers: itsskofficial

Merge Risk: 🔵 Low · up to 869c1

Some approval cards can describe an action inaccurately. These are bounded wording issues, but the label behavior should be corrected or explicitly accepted before merge.

Security architecture risk: ⚪ Minimal · up to 869c1

The approval wording changes without expanding execution permissions. Broader approvals remain constrained by server-generated choices, and sensitive tool warnings remain intact. No material security risk was found introduced or worsened by this change.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The changed exposure is approval presentation for existing tool calls, including browser and device actions. The inspected path does not add execution authority: grant eligibility remains based on server-side tool risk, purchase status, and untrusted-content controls rather than the displayed label.

Trust Boundaries and Controls

  • observed — Browser descriptions derive labels from snapshot element and nearby page text, so the descriptive input is page-influenced. The engine bounds produced descriptions to 120 characters, and the card renders labels as text with tone derived from effective risk. Separately, the browser call-time guard rejects missing, stale, or insufficient risk evaluations for send-looking actions when its confirmation controls are enabled.

Resilience and Maintainability Implications

  • observed — The unchanged approval lifecycle binds responses to a pending approval ID, rejects completed or unknown requests, and removes pending state on completion or timeout. Timeouts deny execution. If saving a broader grant fails after approval, later calls ask again rather than inheriting an unsaved grant.

Explanation

The changes satisfy the coding requirements in [#347]. resolveWording gives browser_click, browser_type, and browser_press labels precedence when riskLabel is present. This produces Clicks for an ordinary click and Purchase for a place-order click. Generic labels and missing labels retain the tool-name rules. The trash-preview override remains first. ApprovalCard uses the resolved label, verb, tone, and icon. Tests cover ordinary clicks, purchases, fallback behavior, unknown labels, and trash previews.

Thanks @azmi2409, this is a nice, careful follow-up, and the precedence and tests read well. Delete, post and plain-click buttons now get the right heading.

I ran the built app against a local shop page (claude-code/sonnet, a fresh home, every card denied):

Button Engine label Card heading
Email via a mail tool (#346) Sends "send an email" ✅
Place order Purchase Purchase ✅
Send feedback Sends Purchase ❌
Subscribe to newsletter Purchase Purchase (engine side, see below)

Two things before this fully closes #347:

  1. A browser click labelled Sends still shows Purchase. This covers Send, Submit, Confirm and Reply buttons. engineWording drops Sends because it equals the generic send fallback, so approvalRisk guesses from browser_click's description ("Buttons that buy, pay…") and gets Purchase. The browser's describe_fn always runs, so could you trust risk_label whenever approval.name.startsWith('browser_')? Or more generally, for tools known to have a describe_fn. Please also add a test for browser_click + Sends → "Sends".
  2. Put the tool-name rules ahead of the engine label. That means terminal_run, and the Home Assistant rules from #372, which is about to land. Otherwise a label like "Unlocks a door" reads as "Sentient wants to do this", and it loses the Home security warning and icon.

Small things:

  • RISK_ICONS as Record<string, Icon> loses the compiler check that every label has an icon. A Record<RiskLabel, Icon> plus a fallback would keep it.
  • The test file imports from the same module twice.
  • A rebase is needed for a CHANGELOG conflict.

"Subscribe to newsletter" reads as Purchase because the engine's _LABEL_RULES classes subscribe as a purchase. That changes what always asks, so we'll handle it on our side.

When a tool's describe_fn names the actual action, the card's heading and
badge use the engine's risk_label: a browser click's describe_fn reads the
clicked element, so an ordinary button reads as a click, 'Send feedback'
reads as sending, and 'Place order' still reads as a purchase. For other
tools the tool-name rules come first (existence-master#346, existence-master#372: terminal_run, Home
security); only when they return a generic label does the engine's label
break the tie, and only when a describe_fn actually ran.

Fixes existence-master#347

Do not trust the generic fallback as a browser-specific label.

describe_call keeps the effective-risk fallback when a browser describe_fn is absent or returns no label. resolveWording accepts that fallback before applying approvalRisk, so a send-risk browser approval can show Sends instead of the Purchase or Deletes wording derived from its reason.

Do not replace the branch with engineWording alone. Sends is both a fallback and a valid browser describe_fn result. Pass provenance that identifies when describe_fn supplied the label, and use the browser override only in that case.

Thanks for the careful rework, @azmi2409! Everything from the last review is done, and the precedence reads really well now. I ran it in the built app against a real engine with a test page:

Button Card heading Badge
Delete account Sentient wants to delete something Deletes
Send message Sentient wants to send something on your behalf Sends
Buy now - $49.00 Sentient wants to make a purchase Purchase (with "Yes, buy it / Don't buy")

On main all three say Purchase, so #347 is fixed. With no risk_label it falls back to the old rules, which is right. Typecheck, build, the 80 desktop tests and CI are all green.

Two small things before merge, one commit should cover both:

  1. Labels not in ENGINE_VERBS read "Sentient wants to do this" (approvalRisk.ts around lines 232 and 273). That covers all of Home Assistant's labels ("Sets a temperature", "Turns something on", "Locks a door"...), which read "make a change" on main. Could the verb fall back to what the rules would have said (approvalRisk(approval).verb) instead? The badge still shows the engine's label, and the heading stays a real sentence. A quick test for home_assistant_set_temperature + "Sets a temperature" would lock it in.
  2. Heads-up on #382, which adds a "Signs up" label for free newsletter buttons. Your browser branch returns first, so once both land that card would say "Sentient wants to do this". Please add 'Signs up': 'sign you up for something' to ENGINE_VERBS (the fallback in point 1 softens it too). Whichever PR merges second takes care of the test-file conflict, so don't worry about that.

Optional:

  • Only browser_click, browser_type and browser_press have an engine describe function, so you could narrow startsWith('browser_') to those three. browser_select would then keep "Changes things".
  • The CHANGELOG entry could end after "still reads as a purchase", since users won't need the tie-break detail.

I'd leave CodeRabbit's "generic fallback label" finding. The engine only sends that when the browser service itself fails, and its own purchase check uses the same label, so the card and the engine agree.

Unknown engine labels (Home Assistant's 'Sets a temperature', the upcoming
'Signs up' from existence-master#382) read 'Sentient wants to do this'. Use what the
tool-name rules would have said for the heading instead; the badge still
shows the engine's label. Narrow the trusted browser branch to the tools
with a describe_fn (browser_click/type/press) and trim the CHANGELOG.

Use a plain verb for unknown engine labels.

If browser_click reports a future label such as Follows, its generic reason can make approvalRisk infer Purchase. Line 296 then shows “Sentient wants to make a purchase” beside a Follows badge. Line 300 also passes a rule verb instead of the specified plain “do this” verb. Use “do this” when an engine label has no known verb, and update the expectation in desktop/tests/approvalRisk.test.ts at Lines 264-268. The PR objective specifies that fallback for unknown future labels.

Also applies to: 300-300
