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.

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 | $0.00087 | $0.02235 |
| Opus 5 | $0.00044 | $0.01118 |
| Sonnet 5 | $0.00017 | $0.00447 |
| Haiku 4.5 | $0.00009 | $0.00224 |
Grade A, and why
archagent-build-workflow 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 4d 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.
This is a copy
91% identical to build-workflow — 33 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 275 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ArchAstro Workflow Builder
Create, edit, and deploy workflows — multi-step processes that agents execute via routines.
This skill assumes the ArchAgent CLI is already installed and authenticated. Install or upgrade archagent if missing, and run archagent auth login <email> if not authenticated.
What is a Workflow?
A workflow is a directed graph of nodes that defines a multi-step process. Use the dedicated top-level workflow resource for authoring: archagent list workflows, describe workflow, create workflow, update workflow, validate workflow, and describe workflowdocs. Workflows are then attached to agent routines for execution.
Always Start with State
Every invocation must begin by understanding the current context:
archagent auth status
archagent list agents
Determine:
- Which agent will run this workflow?
- Is this a new workflow or an update to an existing one?
- What trigger should start it? (schedule, webhook, manual, message event)
Routing
Workflow commands not exposed in the current archagent build
The source tree has dedicated top-level workflow commands, but some archagent builds may not expose them yet. Verify first:
archagent list workflows
archagent describe workflowdocs
If those commands are unavailable, do not keep insisting on them. Fall back to the config-managed workflow path and explain that the dedicated workflow resource exists in source but is not wired into the current binary.
User wants to create a new workflow
Phase 1: Gather requirements
Understand the workflow before writing any config:
- What triggers it? (cron schedule, webhook, message, manual)
- What are the steps? (in plain language)
- Are there branches or conditions?
- Does it need to call external APIs?
- Does it need to send emails, Slack messages, or other notifications?
- Does it loop over a collection?
Discover available events to understand what can trigger the workflow and what data the trigger provides:
archagent list events
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.

archagent-build-workflow is a skill published in the GitHub repository ArchAstro/archagents (5 stars, last pushed 3d ago), licensed MIT. It adds 87 tokens to every session and 2,235 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. It is 91% identical to build-workflow, differing in 33 lines, and is treated as a copy.
