opencode-cache-hit AGENTS.md

A project guide for OpenCode Cache Hit, a sidebar plug-in for the OpenCode terminal interface that shows cache hit rate, tokens, cost, and totals from child sessions.

In plain words
What is it for?
Use it when maintaining the sidebar, its optional JSONL call timeline, token-speed information, or related English and Chinese documentation.
Why use it?
It helps coding agents understand the project’s purpose, documentation, commands, and code conventions before making changes.

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-cache-hit 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 3d 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.

How it starts

The opening of the file, as written. The whole thing — 77 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md — maintainer & AI assistant guide

Instructions for humans and coding agents working in opencode-cache-hit. End-user docs: README.md · README.zh-CN.md.

Project purpose

OpenCode TUI sidebar plugin: cache hit rate, tokens, cost, with sub-agent (child session) rollup. Optional per-call JSONL timeline (timeline.enabled).

Not a fork of opencode-visual-cache. UI patterns and src/tui-panel/ are heavily inspired by visual-cache; product focus differs (see README comparison table).

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.
