Conversation
From Omkar's recording of hilo.cx/onboarding (2026-09-09) and the ladder he described on top of it. Their flow has one rung — connect what Composio already has. Ours has four, and the last three are the point: a bot that cannot do something should not be a dead end. No rung is silent about failing. Falling off one is a message naming what was missing and offering the next. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Rungs 1 and 2 of the tool ladder (docs/plans/tool-ladder.md), from the flow
Omkar recorded at hilo.cx: a bot that needs a tool it does not have used to
say so in prose and stop, leaving the person to go find the integration,
connect it in a settings panel, come back and ask again.
Now it says what it needs in plain words — `need_tool("calendar")` — and the
harness answers with the apps it can actually connect for that: pick one, name
the account, sign in, and the job carries on. The existing connector card and
its resume watch do the last half, so a connection reached this way is
indistinguishable from one the model asked for by slug.
The model owns the capability; the harness owns the slugs. That split is the
point. A model-authored list can name an app that does not exist or that we
have no way to authorize, and a person cannot tell those from a real one until
they have clicked it and waited.
Three things the matcher earned the hard way, each from a test:
- A blurb match is weighted by WHERE the word appears. "Email, calendar and
contacts" is a calendar; "CRM with deals, contacts and a calendar view" is
not, and without this they tie.
- One late mention is not evidence at all — "veterinary records" was
offering Airtable and Salesforce, which would cost a real sign-in for
nothing. A floor drops those.
- …but a capability the catalog genuinely covers still matches: "records"
finds Airtable, which is "Bases and records". The floor drops passing
mentions, not the matcher's nerve.
Escape hatches are load-bearing, not decoration: "I'll connect it later" and
"Choose a different app" are what make the rest safe to click. Declining
resumes the bot with the truth rather than letting the turn time out into a
guess. And a capability nothing answers still draws a card — falling off a
rung is told, never shrugged off. That card is where rungs 3 and 4 (research,
then build) will attach.

Slice 2 of the tool ladder, and smaller than planned on purpose. The plan called for suggested first jobs on a new bot's screen, the way the recording opens with "Create an event in my calendar". Building it turned out to fight a shipped decision: #833 deliberately replaced the onboarding quiz with setup mode, where a blank bot interviews the user about what it should BE. Four chips about calendars are the wrong question at that moment, and a test said so in its name — "a new bot opens with one greeting and no quiz card". That card is not in this commit. What was actually missing sat at the end of the setup prompt, which asked which apps the job touches and then said: go to the Access section of the bot's settings and authorize them by hand. That is precisely the chore this whole flow exists to remove, and setup mode was the one place still handing it over. It now calls need_tool per app instead, so the connecting happens in the same conversation that just worked out what the bot is for — and it still names as manual only what genuinely cannot be done in chat, like a third-party bot token. Also here: the app marquee. A fresh thread shows what this bot could connect, read from the real catalog rather than a marketing list, and it disappears as soon as the user says something. Nothing in it is clickable — connecting happens when a job needs it, not from a directory. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Rung 3 of the tool ladder. When nothing connectable answers a capability, the
card is no longer a dead end: it offers "Look for one", the bot researches
whether a real MCP server or CLI exists, and comes back with propose_tool.
The bot proposes. It does not install, does not run, and does not write a
server. That split is the whole rung, because "search the web, find an MCP,
install it" is mechanically a supply-chain attack: rank a malicious server for
"google calendar mcp" and you have code on the user's computer holding
whatever they connect to it.
What makes the approval real rather than a formality:
- Provenance on screen: package, ONE exact version, publisher, and the
pages the bot actually read, as links. A version range is refused before
anyone sees the card — "^2.0.1" can be a different program tomorrow, under
the same click. So is a proposal with no source, because "the model said
so" is not evidence anyone can act on.
- The publisher is labelled as the page's claim, not ours. We did not check
it, and the card must not lend it our credibility.
- The consent names the consequence — this command will run on your
computer, with access to what you connect — instead of asking whether to
"add an integration".
- The approval is bound by hash to the exact command displayed, and the
fingerprint covers only what EXECUTES. Rewording the pitch cannot
invalidate an approval; changing the program, the version, the arguments
or the environment it reads must, and does.
parseMcpServerMutation still writes new servers inert, and that guard is
untouched: it exists because a command added through the panel has been
reviewed by nobody. This one has — the user approved this exact command with
its provenance in front of them — so the approve route enables it explicitly.
A necessary condition added, not a guard relaxed.

Rung 4, the last one. A dead end now offers "Build one" beside "Look for one":
cli-printing-press generates a CLI and an MCP server from an API's OpenAPI
spec, URL or HAR file, and the bot already has a shell, so this rung needed a
prompt and a proposal shape rather than new machinery.
It lands on rung 3's card, because from the user's side it is the same
decision — new code is about to run on their computer — and the honest
difference is a sentence, not a screen. What changes:
- There is no package and no publisher, and inventing either would be the
one dishonest field on a card built to be honest. Its provenance is the
documentation it was generated FROM, which is required, has to be https,
and is shown as a link the user can open to judge whether it was built off
the right thing.
- The consent says who wrote it: the bot generated this itself, and nobody
else has reviewed it. Generated code is safer than a stranger's package in
one way and not in another, so the card says both.
- The approval is bound by the same hash, and the fingerprint now covers
builtFrom — regenerating from different docs is a different program.
If cli-printing-press is not on the machine the bot says exactly that and
stops, rather than improvising a substitute. We do not install it for them.
docs/plans/tool-ladder.md now records what was actually built, including the
slice that shrank and the three things still open.

…gained Three bugs, found by Omkar testing rung 2 against his real catalog. Asked for analytics, the picker offered Google Analytics and Baremetrics; he answered "no i want posthog data". PostHog is in the catalog. 1. Blurb matches were scored by POSITION, and that was an artefact of the fixture. The curated fallback writes terse phrases — "Analytics, feature flags, experiments" — so the keyword lands first and a position gate looks like signal. The live catalog writes sentences: "PostHog is an open-source product analytics platform" puts it seventh, under the floor, and out of the list. Position is now a ranking hint and never a gate. The regression test uses blurbs copied from the live catalog, which is the shape this should have been tuned against in the first place. 2. searchTerms singularises a word before looking up its synonyms, and the table was keyed "analytics" — so the lookup asked for "analytic", missed, and every analytics synonym was dead code. Keys are singular now, and a test asserts the plural still reaches them. 3. A synonym is a guess made on the user's behalf and is now weighted as one. Without that, "metric" (inferred from "analytics") let Baremetrics — whose SLUG contains it — outrank Google Analytics, whose name is the word that was actually asked for. Also: rung 1 only ever checked Composio, so a tool installed by rung 3 or 4 could never satisfy it — approve a weld MCP, ask again, and get offered a connection for the capability you just gained. It now counts the bot's own enabled MCP servers too, which is the half of the plan I skipped. The remaining blind spot is honest and stated in the tool description: an app connected through Claude Code's own connectors reaches the bot as an MCP tool the harness cannot enumerate. The model checks its own tools first — which is exactly what happened here, correctly, with Google Calendar. The floor now favours recall over precision, deliberately. The person is choosing from a visible ranked list of at most six: a mediocre fourth option costs them a glance, a missing right one costs them the feature.

…ategory Checking the last fix against the live 500-toolkit catalog rather than my fixture showed it was still wrong, in a way the fixture could never have caught. Asked for email it offered Benchmark Email, BlueFox Email and Bulk Email Checker, and left Gmail off the end. Asked for analytics it still missed PostHog, now behind Eventbrite and beaconcha.in. Three causes, all mine: 1. The catalog arrives sorted by USAGE and I threw that away. For a category word, having it in your name is weak evidence — "Bulk Email Checker" is not an email client — while for a brand word it is strong, and no amount of text matching tells those apart. Usage does. It is weighted above a name match on purpose; the filter has already discarded everything that does not match at all, so it only ever reorders apps that genuinely answer. 2. Direct and inferred evidence were being added into one number, so an app containing a SYNONYM could outrank one containing the word the bot actually said. They are separate now: a synonym can break a tie, never win one. 3. "event" was a synonym for analytics. It means two unrelated things, and it was what dragged Eventbrite and beaconcha.in into an analytics picker. Against Omkar's real catalog it now answers: email → Gmail, Outlook; analytics → Google Analytics, BigQuery, Clarity, Mixpanel, PostHog; calendar → Google Calendar, Cal, CalendarHero, Calendly; crm → HubSpot, Apollo, Salesforce. The new test builds a catalog in usage order with the popular apps first and the category-named ones two hundred entries down, which is the shape that actually broke. This remains a text heuristic and it will keep having gaps — "chat" does not find Slack, because its blurb says "messaging" and the stemmer does not join those. The real fix is the category metadata Composio returns and our catalog mapper currently discards. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
… survive Omkar tested rungs 2 and 3 on a real bot and the tool was never called. Asked to pull PostHog data it requested an API key in chat; asked to log a weld inspection it asked which system he uses. Both are precisely what need_tool exists for, and it reached for neither. The tool was mounted and its block WAS in that bot's prompt (560 bytes, and the agents server is alwaysLoad so it is never deferred behind ToolSearch). The prompt just described a principle — "if a job needs an app you have no working tool for" — and a small model (this one runs Haiku 4.5) does not recognise the moment it is in from a principle. So it names the moments instead, as three things to do INSTEAD of the message the bot was about to write: instead of asking for an API key, token or account id; instead of asking WHICH app or system the user uses; and instead of saying it has no access. It also restates the rule the bot broke on its way past — never ask for a credential in chat, request_credential is there for real keys. This improves the odds; it cannot guarantee them. Tool choice is the model's, and the same prompt will behave differently on Haiku than on Sonnet or Opus. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The allowlist is default-deny, so the cards the phones are about to render would be refused without this. Added here rather than on either phone branch: it is one shared file and both ports would collide on it. Each entry is per-action, not per-family. A phone may answer a card, never invent a verb on one — and approving a found or generated tool is held to the same bar as the desktop, since the request carries the hash of the exact command the card displayed and a mismatch is refused host-side.

Delete the installed MCP server in both proposal-test finally blocks.
Approving either proposal persists an enabled server in shared cfg.mcpServers; deleting the bot does not remove it. Capture the successful approval response's body.server, then delete /api/mcp/servers/${body.server} in finally. Use the returned name because the generated proposal is installed as found-tool, not a name containing weld.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Every generated tool derives the same server name, so only the first one can be installed.
A generated proposal must have an empty packageId: proposalError requires builtFrom instead, and shared/tool-proposal.ts documents that a generated tool has no package. mcpServerNameFor("") therefore returns "found-tool" for every generated tool.
The approve route rejects a name that already exists (Line 13823). After the user approves one generated tool, the next generated approval fails with an MCP server called found-tool already exists. Rung 4 becomes single-use per installation, and the user sees an internal server name they cannot act on.
Two distinct packages that normalize to the same string collide the same way (for example @acme/cal-mcp and acme-cal-mcp).
Derive a unique name instead of failing at the collision check.

The setup prompt names need_tool under a weaker gate than the tool itself.
server/index.ts gates NEED_TOOL_PROMPT on integrations.agents && bot.composio !== false && composio.configured(cfg) (Lines 4710 and 1345). It gates this setup block on agentsMounted alone (Lines 4785 and 1335).
A bot with agent tools and Connected Apps disabled therefore receives setup instructions to call need_tool once per app. POST /api/internal/tool-requests answers 409 connected apps are not enabled for this bot (server/index.ts Line 8587). Line 66 also forbids sending the user to a settings panel, so that bot has no sanctioned alternative.

Pin the expected issues ranking.
matchToolkits uses the catalog index as a popularity input. Reversing CATALOG therefore changes the ranking input, while toEqual(twice) does not require any result or expected order. No other test exercises "issues", so an issue-specific regression can return no candidates or place GitHub before Linear without failing. Use the same CATALOG for both calls and assert ["Linear", "GitHub"].

singular over-strips words that end in "-es", so those plurals never reach SYNONYMS.
singular("issues") returns "issu", because "issues" ends with "es" and not with "ses". The same happens for "invoices" → "invoic", "messages" → "messag", and "notes" is fine only by luck of the -s rule order. Direct matching still works, because labels and blurbs pass through the same function. But SYNONYMS[word] misses, so a person who writes the plural loses synonym expansion — exactly the failure the file's own comment describes for "analytics".
Strip only -es after a sibilant stem, and fall back to the plain -s rule otherwise.

Send the suggested account name when the field is empty.
suggestion is only a placeholder, so an untouched field submits alias: "". The placeholder tells the user the account will be named after the app, and defaultAccountName is documented as "the name the account is saved under when the user accepts the suggestion". Accepting the suggestion means pressing Continue without typing. Fall back to suggestion so the saved alias matches what the card showed.

[P1] Bind the approved version to the executable. This accepts packageVersion >=1.2.3, and also accepts version 1.2.3 paired with npx args selecting @latest. Both produced approvable cards in the isolated fixture. Hashing the proposal does not pin what a later invocation downloads. Require an exact version and verify supported launcher arguments actually select that package/version; reject unsupported or unpinned forms.

[P1] Do not install ordinary CLI proposals as enabled MCP servers. The route ignores proposal.kind: approving kind=cli persisted its command as an enabled MCP entry. The consent describes using a CLI when needed, but MCP entries are mounted on subsequent supported turns and can run for other bots. A normal CLI cannot answer the MCP handshake and may repeatedly perform its operation. Provide a separate CLI installation path or reject this kind until supported.

[P2] Give generated tools distinct installation identities. Generated proposals omit packageId, so they all become found-tool here. In the real-server fixture the first approval succeeded and the second distinct generated tool returned 409. Derive a collision-safe identity from the proposal instead of using the same fallback for every generated tool.

[P2] Render these approval cards in room conversations too. The server accepts room-owned tool requests/proposals and asks the agent to wait, but only ChatView handles the new fields. GroupView still recognizes only the existing permission cards, so room users get no usable approve/decline UI and cannot continue the request.

From Omkar's recording of
hilo.cx/onboarding: you say what you want done, and the connecting happens in the conversation, one step at a time, with a way out at every step.A bot that needed a tool it did not have used to have one move — say so in prose and stop. Everything past that was the user's problem: find the integration, connect it in a settings panel, come back, ask again.
Hilo's flow has one rung. This has four, and the last three are the point: a bot that cannot do something should not be a dead end.
cli-printing-press, and propose thatNo rung is silent about failing. Falling off one is a message naming what was missing and offering the next.
Rungs 1–2
need_tool("calendar")— the model names a capability in plain words, never a vendor and never a slug. The harness answers with the apps it can actually connect, because a model-authored list can name a provider that does not exist or that we have no way to authorize, and a person cannot tell those from a real one until they have clicked it.Then the account name — which we have always stored (
normalizeAccountAlias, multiple accounts per toolkit) and had never once asked a person for. It is asked at the moment it means something, with the reason attached: it is the name the bot will say back to you when it asks to act.The existing
ConnectorCardandmaybeResumeConnectorsfinish the job, so a connection reached this way is indistinguishable from one the model asked for by slug.Escape hatches are load-bearing, not decoration. "I'll connect it later" resumes the bot with the truth — they chose not to, carry on and say what you can't do — rather than letting the turn time out into a guess.
Rung 3 — and why the approval is real
This is the rung with teeth. "Search the web, find an MCP, install it" is mechanically a supply-chain attack: rank a malicious server for "google calendar mcp" and you have code on the user's computer holding whatever they connect to it.
So the bot proposes. It never installs, never runs, never writes a server.
^2.0.1can be a different program tomorrow, under the same click.parseMcpServerMutationstill writes new servers inert, and that guard is untouched — it exists because a command added through the panel has been reviewed by nobody. This one has, so the approve route enables it explicitly. A necessary condition added, not a guard relaxed.Rung 4
cli-printing-pressgenerates a CLI and an MCP server from an OpenAPI spec, URL or HAR file. The bot already has a shell, so this needed a prompt and a proposal shape rather than new machinery. It lands on rung 3's card, because from the user's side it is the same decision.Generated code has no package and no publisher, and inventing either would be the one dishonest field on a card built to be honest — so its provenance is the documentation it was generated from, required, https, and shown as a link. The consent says who wrote it: the bot generated this itself; nobody else has reviewed it.
If
cli-printing-pressis not on the machine the bot says exactly that and stops. We do not install it for them.What testing changed
Omkar ran this against his real catalog and it was wrong three times. Each fix is a commit:
"Analytics, feature flags, experiments") so I scored blurb matches by position. The live catalog writes sentences —"PostHog is an open-source product analytics platform"puts the word seventh — and the position gate dropped exactly the app he uses. Position is a ranking hint now, never a gate.searchTermssingularises before looking up synonyms, and the table was keyed"analytics"— so every analytics synonym was dead code.Setup mode
The plan called for suggested first-job chips. Building them fought #833, which deliberately replaced the onboarding quiz with setup mode — a test says so in its name. The chips are not here. What was actually missing was the end of the setup prompt, which sent people to Settings → Access to authorize apps by hand. It calls
need_toolnow.Platforms
Package Windowsrun started on this branchrequestId, so they render inert — title and subtitle, no buttons. Port in progressios/Appandroid/app/.../uiTest plan
typecheck,lint,i18n:checkclean.shared/tool-request.test.ts— matching, ranking, the score floor, and a catalog built in usage order with the category-named apps two hundred entries down, which is the shape that actually broke.shared/tool-proposal.test.ts— version ranges and sourceless proposals refused; the fingerprint changes when the program changes and not when the words do.server/index.test.ts— capability → real slugs; an app the card never offered is refused; approving without echoing the displayed hash is refused; nothing is installed until it is approved; a generated tool needs its documentation.companion/test/routes.test.ts— a paired phone may answer a card, never invent a verb on one.Known limits
chatdoes not find Slack: its blurb says "messaging", the matcher looks for "message", and the stemmer does not join them. The proper fix is the category metadata Composio returns and our catalog mapper discards.🤖 Generated with Claude Code
