* fix(agiloft): make the block work, and align it with the REST documentation
The native Agiloft block could not authenticate against any instance. A
customer reported it; production traces for their workspace confirm every
failure mode verbatim. Fixing that exposed a second, larger problem, and a
per-endpoint audit against the full published documentation found the rest.
Authentication
- EWLogin sent only $KB/$login/$password as query parameters. A live instance
answers `400 EWWrongDataException ... One has to specify $table, $KB, $lang
parameters`. $table is required even though only $KB/$login/$password/$lang
are documented. Parameters now travel in a form-encoded body, which the docs
permit and which keeps the password out of URLs and access logs.
- The authentication scheme is read from the login response and trimmed;
Agiloft returns it as "Bearer " with a trailing space.
- EWLogout was missing $lang.
Surfaces
- Record create, read, update, search and saved-search now use the endpoints
that accept the token EWLogin issues; the legacy operations authenticate from
inline credentials, which is what that surface expects. Nothing sends both
forms at once — the documented 400 for doing so is what the original report
had run into.
- EWSelect passes credentials in a POST body, one of the five operations
documented to support it.
- Attachment retrieval uses the documented EWRetrieve endpoint, with
filePosition rather than position, and no longer needs a login/logout pair.
Defects found in the audit
- remove_attachment reported zero on every call: its body is the EWREST
assignment form but the route ran JSON.parse then Number(), yielding NaN.
- The EWREST parser could not read EWActionButton's documented response, which
puts both assignments on one line.
- EWLock treated any 200 as success, including the documented
{error, error_description} envelope, and invented an 'UNKNOWN' status.
- EWTable discarded the linked-field details, required flag and text field type
it had asked for, making includeLinkedInfo inert.
- select_records had no result ceiling at all; both it and search now cap and
report a truncated flag rather than reporting a capped length as a total.
- Optional string inputs rejected null, so a blank Page field failed validation
before any request was made.
- Upsert treated the documented 202 async acknowledgement as a missing-ID
failure, and returned no callback ID for the caller to poll.
- Every response contract required an output that the 401 and 500 paths never
return.
Coverage added
- Table and field discovery (EWTable), upsert (EWUpsert), async status
(EWAsyncStatus), natural language search (EWNLPSearch), action buttons
(EWActionButton), the REPLACE_WITH_ANOTHER delete rule with its substitute
records, $async on upsert, and <fieldName>$overwrite on attach.
- Reads with a named field list go through the search projection; an unfiltered
contract record runs to roughly 184KB and swamps downstream agent context.
- Errors are readable: Agiloft wraps failures in HTML around a typed exception
and an internal task id, and the JSON endpoints now request real status codes
rather than a 200 the caller has to interpret.
Not implemented: $searchSQL and $operationHints=NOLOCK are EWRead/EWUpdate
parameters and those operations do not run on that surface here; EWQuestion,
EWHotlinks, EWOData, EWBroadcast and webhook registration have no documentation
beyond their names.
Verified against the published documentation, not against a live instance.
* fix(agiloft): give natural language search a sentence that paints
check:canvas-sentences failed: the nlp_search card resolved to nothing on an
untouched canvas, so it painted empty. Its only basic-mode field was the
long-input query, and the field list is advanced, so every segment dropped.
The sentence now leads with the knowledge base, matching the shape List Tables
already uses — both operations are knowledge-base scoped rather than
table-scoped, so it also reads more accurately.
* fix(agiloft): stop retrying refusals, and expose the outputs the new operations return
Five findings from review that had gone unanswered.
An Agiloft refusal was surfacing as HTTP 500. readAlrestJson throws when the
envelope reports success:false, the route catch mapped that to 500, and the
tool runner retries 500s — so a create the server had already rejected could be
retried and duplicate the record. Refusals now return a settled failure with the
message intact; genuine faults still 500.
list_tables could not run in its primary mode. EWTable is knowledge-base scoped,
but some instances reject EWLogin without a $table, so whole-knowledge-base
discovery failed at login with nothing to fall back to. It now says what the
caller can do about it rather than surfacing the raw login error.
Upsert corrupted structured values. Every field went through String(), so a
multi-value field collapsed into one joined string instead of the documented
repeated key/value pairs, and an object silently wrote "[object Object]" into
the record. Arrays now encode as repeated pairs and objects are refused, since
Agiloft documents no encoding for them.
Two outputs were invisible in the editor. `records` was conditioned on
search_records alone, so natural language search results could not be chained,
and `callbackId` on run_action_button alone, so a queued upsert's callback could
not be wired into Async Status even though both values exist at runtime.
A workspace to build, deploy and manage AI agents and workflows.
Quickstart
Cloud-hosted: sim.ai
Self-hosted
git clone https://github.com/simstudioai/sim.git && cd sim
bun install
bun run setup
Capabilities
- Connect 1,000+ integrations and every major LLM
- Add Slack, Notion, HubSpot, Salesforce, databases, and more
- Build agents visually, conversationally, or with code
- Ingest files, knowledge bases, and structured table data
- Monitor runs, logs, schedules, and workflow activity
One workspace, every surface
Chat and workflows are just the start — tables, files, and knowledge all live in the same workspace.
Tables — a database, built in |
Files — one store for your team and every agent |
Knowledge — your agents' memory |
Self-hosting
bun run setup is an interactive wizard: it provisions the database, generates secrets, writes your .env files, connects a Chat API key, and starts Sim the way you choose:
- Local dev — run from source to contribute or hack on Sim
- Docker Compose — a self-contained instance for testing self-hosting
- Kubernetes (Helm) — deploy to a local cluster
When it finishes, open http://localhost:3000.
Reconfigure an optional capability without rerunning the full wizard:
bun run setup status
bun run setup email
bun run setup storage
bun run setup sandbox
bun run setup jobs
bun run setup cache
bun run setup knowledge
bun run setup llm
bun run setup integration slack
bun run setup status detects the effective local-dev, Docker Compose, or current-context
Helm configuration and reports configured, missing, or invalid capabilities and OAuth
integrations without printing credential values. This is separate from bun run sim status,
which reports whether installed services are running and healthy.
Manage your install with bun run sim:
bun run sim start | stop | restart # bring your install up / down / cycle
bun run sim update # pull/rebuild and apply Compose images
bun run sim status # what's installed and healthy
bun run sim logs # follow logs
bun run sim doctor # diagnose configuration problems
bun run sim down # remove containers (data kept)
bun run sim reset # archive .env and wipe managed data
sim detects how you're running (Docker Compose, local dev, or Kubernetes) and acts accordingly.
Prefer a bare sim? Run bun link once — but note sim lands in ~/.bun/bin, which Homebrew's bun doesn't add to your PATH, so you may need export PATH="$HOME/.bun/bin:$PATH" in your shell profile.
Sim also supports local models via Ollama and vLLM. See the self-hosting docs for details.
Chat API Keys
Chat is a Sim-managed service. bun run setup connects a Chat API key for you — sign in when it opens your browser and the key is stored automatically. To view, create, or revoke keys later, go to sim.ai/selfhost/settings/chat-keys.
Environment Variables
See the environment variables reference for the full list, or apps/sim/.env.example for defaults.
