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 | $0.00079 | $0.00383 |
| Opus 5.5 | $0.00032 | $0.00153 |
| Sonnet 5.5 | $0.00016 | $0.00077 |
| Haiku 4.5 | $0.00008 | $0.00038 |
Grade A, and why
archagent-auth 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.

What it actually says
ArchAgent CLI Authentication
Authenticate the user with the ArchAstro developer platform via browser-based login.
Workflow
-
Check whether the user is already authenticated:
archagent auth statusIf the user is already authenticated, show their status and ask whether they want to re-authenticate.
-
Reset any stale settings overrides that may point to localhost:
archagent settings resetThis ensures the CLI uses the production URLs.
-
Start the login flow:
archagent auth login <email>Keep the session responsive while the browser-based auth flow runs.
-
Tell the user the auth flow is running and they should complete login in their browser. The CLI opens
https://developers.archastro.aiand prints a URL if the browser does not open automatically. -
When the user says they have logged in, or when it is time to re-check, wait for the login command to finish and then run:
archagent auth status -
On success, confirm authentication succeeded and show the user their status.
-
On failure, show the error and suggest:
- Check their internet connection.
- Try
archagent settings resetif URLs look wrong. - Try again with
archagent auth login <email>.
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.
