AGENTS.md

devspace-ultra AGENTS.md is an instructions file for Codex, OpenCode from enwong93-sketch/devspace-ultra. It costs 1,570 tokens per session, scanned A, original, MIT.

A set of AGENTS.md instructions for the DevSpace Ultra project. AGENTS.md is a file of rules that guides a coding agent's behaviour while it works in a repository.

In plain words
What is it for?
Controlling how DevSpace Ultra sessions handle read-only investigations, risky changes, progress plans, and routing work across available tools.
Why use it?
It gives the agent project-specific rules for approvals, progress updates, and when to use different capabilities.

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.

Security

Grade A, and why

devspace-ultra AGENTS.md 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 today.

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.

DevSpace Ultra Agent Notes

Execution approval

When the user explicitly asks this DevSpace Ultra plugin session to investigate, research, diagnose, audit, inspect, or run a non-destructive read-only probe, treat that request itself as approval to begin immediately. Do not insert a separate “continue?”, “start?”, or design-approval checkpoint before gathering evidence.

Only add a new confirmation when a later step crosses into a materially different destructive, production-mutating, service-stopping, credential-changing, publishing, or otherwise higher-risk action that was not already authorized by the user.

Interactive ChatGPT progress routing

Every user-facing ChatGPT Classic Main conversation uses one conversation-scoped floating DevSpace progress narration card. Never rely on, create, or remount the retired inline black Goal Dock or inline Plan Card as the progress surface.

Before the first substantive work tool in any task expected to require more than one tool call, more than roughly 30 seconds, or multiple verification gates, start or resume exactly one conversation-bound DevSpace Plan. When the requested outcome needs autonomous continuation across assistant turns, start or resume Goal Mode first and keep a fresh turn-scoped Plan beneath it. Keep Goal and Plan state current as execution structure and backend telemetry; neither tool events nor timers may author visible narration.

Visible progress is authored only by the working Agent. Call devspace_progress_report when a meaningful medium-sized step has completed, an important verification result is available, the execution direction materially changes, or a genuine blocker is useful to report. There is no fixed time or tool-count cadence, and low-level tool events, timers, heartbeat rows, step counters, and generic status boilerplate must never be shown as narration. Write the update yourself in natural language for this user and current task. The report binds to the current authoritative conversation and waits for identity correlation instead of failing on a short wall-clock deadline. Do not expose hidden reasoning, and do not create synthetic user turns, reloads, or navigation merely to update progress. A genuinely atomic one-tool task may leave the blank conversation card untouched.

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.
