What is openmelon CLAUDE.md?

A project guide for openmelon, a content-creation agent command-line tool with interactive, headless, and public programming interfaces.

Working on openmelon’s command-line commands, interactive terminal interface, project and content registries, local installation, and Go packages.

It gives the coding agent the repository’s structure, commands, setup instructions, and usage rules.

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	$0.02113	$0.02113
Opus 5.5	$0.00845	$0.00845
Sonnet 5.5	$0.00423	$0.00423
Haiku 4.5	$0.00211	$0.00211

Security

Grade A, and why

openmelon CLAUDE.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 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 this is

openmelon is a content-creation agent CLI. Three usage modes:

Interactive TUI — openmelon (no args, in a project) drops into a bubbletea REPL with slash commands, palette, model + skill pickers, bash approval modal, session resume.
Headless prompt — openmelon -p "<intent>". Inside an OpenMelon project, runs the same tool-driven runtime as the TUI without the TUI. Outside a project, falls back to the legacy one-shot skillplus → LLM JSON → optional image/artifact path. Used by integrations and scripts.
Public Go surface — pkg/openmelon currently exposes version metadata; pkg/contracts holds public contract types for embedding/integration surfaces.
