Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.
npx agentmods add agents/sstraus/tuicommander/opencodegit clone --depth 1 https://github.com/sstraus/tuicommanderWhat 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 | $0.00000 | $0.02856 |
| Opus 5 | $0.00000 | $0.01428 |
| Sonnet 5 | $0.00000 | $0.00571 |
| Haiku 4.5 | $0.00000 | $0.00286 |
Grade A, and why
opencode 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 2d 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 — 271 lines — stays where its author put it; the contents beside it link to each section on GitHub.
OpenCode — UI Layout Reference
Agent-specific layout reference for OpenCode. See agent-ui-analysis.md for shared concepts.
Observed version: v1.2.20 (2026-03-22), re-audited on v1.18.5 (2026-08-02) Rendering engine: Bubble Tea (Go TUI framework) Rendering approach: Full-screen TUI, ANSI absolute positioning, mouse tracking
Key Difference from Other Agents
OpenCode is a full-screen TUI application, not a CLI that renders inline in the terminal like Claude Code or Codex. It takes over the entire terminal screen with its own layout, panels, and navigation. This means:
- The "bottom zone" concept from CC/Codex does not directly apply
- OpenCode manages its own screen regions (panels, status bar, prompt)
- Mouse tracking is enabled (
\033[?1000h,\033[?1003h,\033[?1006h) - It uses bracketed paste (
\033[?2004h) and focus events (\033[?1004h)

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.

opencode is an agent published in the GitHub repository sstraus/tuicommander (123 stars, last pushed 5d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 2,856 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
