A local development command that starts the project in either self-hosted or software-as-a-service mode. It handles deployment-mode detection, SaaS safeguards, cookie prefixes, and the Turbopack build-cache issue.

Use /dev with self-host or saas, and optionally clean or stop, to start, reset, or stop the local development environment.

It avoids common local-startup problems caused by different deployment modes and cached development builds.

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	$0.00050	$0.02034
Opus 5.5	$0.00020	$0.00814
Sonnet 5.5	$0.00010	$0.00407
Haiku 4.5	$0.00005	$0.00203

Security

Grade C, and why

dev scanned grade C with 2 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

- API: `curl -sf http://localhost:3001/api/health` returns (503 is fine — means it's serving; the app answers even when a provider key is missing).

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.

dev is a command published in the GitHub repository AtlasDevHQ/atlas (1 stars, last pushed 1mo ago), licensed AGPL-3.0. It adds 50 tokens to every session and 2,034 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it C with 2 findings (recursive force delete, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
