What is workflows-ai-by-zapier?

A procedure for adding an AI reasoning step to a Zapier workflow, including context, outputs, connected tools, web search, and a failure path. Zapier is a service for connecting apps into automated workflows.

Use it when a workflow needs language-based decisions or AI-directed searches and app lookups.

It helps configure the AI step from Zapier's current action definitions instead of guessing the required fields and nested data structures.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add zapier/agent-skills --skill ai-by-zapier

Clone the repo

git clone --depth 1 https://github.com/zapier/agent-skills

Made for: Claude Code.

Or install agent-skills, the plugin that ships this one along with the rest of its 7 skills.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00058	$0.03733
Opus 5.5	$0.00023	$0.01493
Sonnet 5.5	$0.00012	$0.00747
Haiku 4.5	$0.00006	$0.00373

Security

Grade A, and why

workflows-ai-by-zapier scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

AI by Zapier Workflow Steps

Use this companion with workflows-create or workflows-modify; it sets up the bounded AI step but does not replace the workflow lifecycle. If the request involves creating, testing, publishing, or enabling a complete workflow and neither lifecycle skill is loaded, load the appropriate one first.

SDK CLI discovery

Use the public SDK CLI's live catalog before writing the AI step:

Find the current implementation: zapier-sdk list-apps --search "AI by Zapier" --json.
Inspect actions: zapier-sdk list-actions <appKey> --json.
Inspect editable fields: zapier-sdk list-action-input-fields <appKey> <actionType> <actionKey> --json.
Prefer the complete contract: zapier-sdk get-action-input-fields-schema <appKey> <actionType> <actionKey> --json; retain the whole data schema, including nested contentSchema and root references. If that discovery is unavailable, use the version-scoped basic fallback below, not an invented nested contract.
Resolve dependent choices: zapier-sdk list-action-input-field-choices with the settled parent inputs.
Resolve an embedded app's connection: zapier-sdk list-connections <appKey> --owner me --json. Match the intended account by its returned name/label, paginate as needed, and ask when ambiguous. If none is usable, use the installed SDK's supported connect/reconnect flow and rediscover after the user finishes; never ask for raw credentials.

Keep three namespaces separate:

Managed model credentials: inputs.authentication_id: "0"; no outer connection lookup is needed for this selector.
Model BYOK: use the authentication_id field choice's returned value after settling its provider dependencies, not a UUID from list-connections.
Embedded app tools: copy the selected connection's public UUID id from list-connections unchanged into tools[].connection_id. Use a version whose live contract or the validated fallback supports this field. A legacy numeric auth_id is usable only when discovery supplies that format; never decode or coerce a UUID. For connectionless tools, omit both references.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
