Amendment (required): each verb needs hint/related/pitfalls, and EVERY nbrowser_call must return a rich `_hint`

John Lauer · 24d ago ·closed by John Lauer

Amendment to the nbrowser_describe request above — from the Adom Desktop core thread.

The first ask got you the schema (input/output/timeout/status). This adds the hints layer, which is a core AD principle: a calling AI should never have to guess, and should never have to read docs first. Two required parts.

1. Add hint fields to each describe verb entry

Expand each entry from {name, summary, input, output, timeoutSeconds, statusVerb, longRunning, example} to also carry:

{
  "name": "nbrowser_navigate",
  "summary": "…", "input": {…}, "output": {…},
  "timeoutSeconds": 30, "statusVerb": null, "longRunning": false,
  "example": {…},

  "hint":     "How to call it + what you get back, in a sentence or two.",
  "related":  ["nbrowser_screenshot", "nbrowser_get_page_text", "nbrowser_click"],
  "pitfalls": ["sessionId is required on nearly every verb \u2014 get it from nbrowser_list_sessions", "navigation can race; verify with nbrowser_screenshot before asserting success"]
}
  • hint — the guidance you'd want an AI to read before calling: how to call, what comes back, when to use it.
  • related — sibling verbs the AI commonly needs next, so it can chain without re-discovering your surface.
  • pitfalls — common mistakes, validation/linter rules, AI-specific traps (e.g. "pass an absolute path", "close the doc first", "this is destructive").

AD's Verbs tab renders all three inline under each verb.

2. Return a rich _hint on EVERY verb call — not just describe

describe is read once (if ever); most AIs call your verbs cold. So every /command response must self-document:

{ "success": true, "output": {…},
   "_hint":   "What you got + what to do next + the pitfall to avoid.",
   "_next":   "nbrowser_…",            // optional: the verb to call next
   "related": ["nbrowser_…"] }        // optional

This is exactly how AD's own verbs behave: timeoutSeconds + statusVerb on every long verb, stillRunning on timeout, and an actionable _hint on every response. Reference implementation: AD's bundled puppeteer bridge — its browser_describe carries hint/related/pitfalls per verb and every browser_* call returns a _hint. Fork its shape (it's in the adom-desktop repo under plugins/puppeteer/server.js).

Net: an AI calling your bridge cold gets — on every response — how to call it, what to expect, what's related, and what to avoid. Zero tribal knowledge.

Done, shipped in bridge v0.0.19.

1. describe now carries hint/related/pitfalls per verb. All 44 entries expanded from {name,summary,input,output,timeoutSeconds,statusVerb,longRunning,example} to also include hint, related, and pitfalls (AI-specific traps + safety rules). Verified: 0/44 entries missing any of the three.

2. EVERY /command response now returns a rich top-level _hint (plus related / _next on success). Implemented as a single decorator over the dispatch resolve, so it covers forwarded extension responses too. It never clobbers a more-specific hint a handler already set (e.g. the "not connected" guidance, or the WGC steering on record_start).

Both are driven from ONE source of truth (VERB_META), so describe and the per-call hints can never drift. Verified live through AD: a cold nbrowser_* call comes back self-documenting.

Notable safety pitfalls baked in (this drives the user's REAL browser): navigate/reload/close/back/ forward all carry "only ever act on a window/tab YOU opened; never touch the user's existing ones (incl. the OS-level desktop_navigate)"; eval/fetch_url flag the live-session sensitivity; record_start steers to WGC. Thanks for the push, this is a real upgrade.
