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 5.1 | $0.00084 | $0.01262 |
| Opus 5.5 | $0.00034 | $0.00505 |
| Sonnet 5.5 | $0.00017 | $0.00252 |
| Haiku 4.5 | $0.00008 | $0.00126 |
Grade A, and why
archagent-concepts 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 2mo 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 — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ArchAgents Concept Map
Every ArchAstro support conversation eventually hits a concept question.
Answer it with the platform's real vocabulary, not your own paraphrase.
When you are unsure, link the customer to the canonical doc (see the
archagent-docs-map skill) rather than inventing a definition.
Primary nouns
AgentTemplate
A YAML file with kind: AgentTemplate that declaratively defines an
agent's identity, tools, routines, and installations. Version-controlled
in git. Deployed with archagent deploy agent <file>.yaml. The source
of truth for what an agent is.
Agent
A deployed, persistent AI worker created from an AgentTemplate. Has a name, identity prompt, tools, knowledge, memory, and routines. Lives on the ArchAgents platform and is addressable across threads, webhooks, schedules, and API calls.
Thread
A persistent conversation where human users, system users, and agents
exchange messages over time. Supports multiple participants and
cross-company collaboration. Agents join threads via
thread.session.join routines and leave via thread.session.leave.
Routine
An agent-scoped event handler. Attached to a specific agent; fires
when a matching event (schedule.cron, webhook.*,
thread.session.join, etc.) occurs. Routines are the primary way an
agent reacts to the world.
Automation
A project-scoped event handler. Same event-and-handler shape as a routine, but not tied to a single agent. Use for project-wide jobs (e.g., a webhook that fans out to multiple agents).
Script
The smallest unit of custom logic. A functional, expression-oriented
language (no loops, no return statement) authored in .aascript
files. Used as a tool handler, a workflow node handler, or a routine
handler. Authoritative syntax: archagent describe scriptdocs.
Workflow
A directed JSON graph of nodes (WorkflowGraph kind) referenced by a
routine when a handler needs branching, approvals, retries, or
multi-step state. Prefer a routine + single script for simple handlers;
reach for a workflow only when you need structure.
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-concepts is a skill published in the GitHub repository ArchAstro/archagents (7 stars, last pushed 29d ago), licensed MIT. It adds 84 tokens to every session and 1,262 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-08-31.
