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.

Security

Grade A, and why

hera-godot 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 24d 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

Hera live Godot workflow

Use Hera only with a running Godot editor where the Hera Agent Godot addon is enabled (verified on Godot 4.2–4.7; 4.7 recommended). Treat CLI output as the source of truth for live editor and runtime state.

  1. Start with hera-godot status. If it finds no editor, ask the user to enable the addon under Project Settings → Plugins. If several editors are present, run hera-godot instances and use hera-godot --instance <pid> for mutations.
  2. Before UI work, run hera-godot guidance ui. Keep reads compact: prefer hera-godot --ids scene tree, node get --prop/--props, scoped game ui tree, and game qa discover before full dumps.
  3. Use undoable editor commands (node add/set/remove, signal connect/disconnect) for normal changes. Do not use eval as a shortcut for a normal write. Scene/resource/script/project changes persist; game node set/call, game click, and game input are runtime-only.
  4. Prove each change: re-read the node/property or tree, check hera-godot output --type error or hera-godot diagnostics after runs, and use hera-godot screenshot --runtime --analyze plus game ui tree/semantic clicks for visual QA. Use requirement-covered game qa --file scenarios when validating a prompt implementation.
  5. After editing GDScript, run the project's headless --check-only gate when available. Never print or commit HERA_AGENT_GODOT_TOKEN.

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.
