Repository instructions for OpenCode-Relay, a JetBrains IDE plugin that brings the OpenCode AI coding assistant into IntelliJ-based editors. They describe project rules and which JetBrains tools to prefer when working on the code.

In plain words
What is it for?
Use them when changing the plugin, including its editor tool window, settings, lifecycle management, or its integration with the OpenCode command-line program.
Why use it?

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

OpenCode-Relay 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 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.

Prefer JetBrains Tools

When searching the code base or attempting to run a build Take a look at the available run configurations(webstorm_get_run_configurations) Always prefer jetbrains_* tools over generic alternatives when both are available:

Task Prefer Over

Create a file jetbrains_create_new_file Write / echo
Find files by name jetbrains_find_files_by_name_keyword Glob / find
Find files by pattern jetbrains_find_files_by_glob Glob / find
Search content jetbrains_search_in_files_by_text or jetbrains_search_in_files_by_regex Grep / rg / grep
Browse directory jetbrains_list_directory_tree ls / find
Rename symbols jetbrains_rename_refactoring text search-replace

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.
