flash-mod-bridge: Instructions file for Codex

AGENTS.md

flash-mod-bridge AGENTS.md is an instructions file for Codex, OpenCode from rkuhn153/flash-mod-bridge. It costs 219 tokens per session, scanned A, original, MIT.

Repository instructions for the Flash mod bridge, a local connection between an agent and Flash games running in a modified Ruffle player. They describe the required checks, tool order, and object paths.

In plain words
What is it for?
Use them when inspecting Flash game objects, changing properties, calling game functions, or working with saved game data through the bridge.
Why use it?
They help prevent changes from being sent to the wrong player or game object, and require reading values back after a change.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is rkuhn153/flash-mod-bridge's own configuration. It tells Codex and OpenCode how to work on flash-mod-bridge itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything flash-mod-bridge configures →

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

flash-mod-bridge 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 1mo 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

Flash mod-bridge — agent rules

MCP server id: flash-mod-bridge
Hub: http://127.0.0.1:8767

Mindset

  1. Ruffle fork only — Coolmath AwayFL will not expose modBridgeRpc until rehosted on this player.
  2. Ping first — ping_flash_bridge before mutations.
  3. Find before set — flash_find / flash_list_so / flash_list_props.
  4. One write at a time, then flash_get readback.
  5. Prefer structured tools over raw flash_mod_rpc.

Tool order

ping_flash_bridge
  → flash_ping
  → flash_list_display / flash_find
  → flash_list_so / flash_list_props
  → flash_get / flash_set / flash_set_so_prop / flash_call

Changes

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.
