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.

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 | $0.00047 | $0.00664 |
| Opus 5 | $0.00023 | $0.00332 |
| Sonnet 5 | $0.00009 | $0.00133 |
| Haiku 4.5 | $0.00005 | $0.00066 |
Grade A, and why
workflows-history 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 12d 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.
How it starts
The opening of the file, as written. The whole thing — 74 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Zapier Workflows History
Use the public SDK CLI experimental command surface. Do not use zapier-sdk-code-substrate.
Compatibility Gate
Before using this skill, run the workflows-doctor bundle compatibility check. If workflows-doctor is not installed or cannot be loaded, run workflows-install or install workflows-doctor from zapier/agent-skills before continuing. If workflows-doctor reports SDK/skill drift, follow its refresh instructions, stop this skill invocation, reload the agent workspace if needed, and ask the user to rerun the original request.
Identify The Workflow
If the user provides a workflow ID, use it directly.
If the user refers to the workflow by name or description, list workflows first and find the matching ID:
zapier-sdk --experimental list-workflows --json
If multiple workflows match, show the candidates and ask the user which one they mean.
Fetch Run History
zapier-sdk --experimental list-workflow-runs <workflow-id> --json
Parse the JSON output. Useful fields may include id, status, started_at, finished_at, input, and output.
When the workflow ID is known, include the Zapier editor link:
https://zapier.com/durables-editor/<workflow-id>
Drill Into A Run
If a single deployed workflow run failed or the user wants step-level detail:
zapier-sdk --experimental get-workflow-run <run-id> --json
Use get-durable-run <run-id> only for one-off synthetic runs created by zapier-sdk --experimental run-durable, not for deployed workflow runs returned by list-workflow-runs.
If a manual trigger response returns a trigger ID before a workflow run ID is available, bridge from trigger to run:
zapier-sdk --experimental get-trigger-run <trigger-id> --json
Summarize the failure, status, timing, input, output, and any step error details that appear in the response. Avoid dumping raw JSON unless the user asks for it.
Draft State
Runs execute published versions — unpublished draft edits never show up in run history. If the user expects a recent change to be reflected in runs and it isn't, check for an open draft holding that change:
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.
- 12d ago First seen · 74 lines · 47 tokens per session scan A 851369a3d233
workflows-history is a skill published in the GitHub repository zapier/agent-skills (18 stars, last pushed 18d ago), licensed MIT. It adds 47 tokens to every session and 664 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
