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.

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 | $0.00400 |
| Opus 5 | $0.00000 | $0.00200 |
| Sonnet 5 | $0.00000 | $0.00080 |
| Haiku 4.5 | $0.00000 | $0.00040 |
Grade A, and why
agent-terminal 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.
What it actually says
Agent Terminal
Browser-based xterm.js terminal providing direct access to the agent's Claude Code TUI, with mode switching between Claude, Gemini, and Bash.
How It Works
- Open the agent detail page and click the Terminal tab.
- The terminal connects via WebSocket to the agent container's PTY.
- The default mode is the Claude Code TUI (interactive AI assistant).
- A mode toggle in the terminal header switches between Claude, Gemini, and Bash:
- Claude -- Claude Code interactive mode.
- Gemini -- Gemini CLI (requires
GEMINI_API_KEYcredential). - Bash -- Raw shell access to the agent container.
- The terminal supports resize and adapts to the browser window dimensions.
- Per-agent API key control: toggle between the platform API key and your own Claude subscription in the Terminal tab.
SSH Access
- Admin-only: SSH access is restricted to admin users for security.
- Generate ephemeral SSH credentials via the API or MCP.
- ED25519 keys with configurable TTL, controlled by ops settings.
- API:
POST /api/agents/{name}/ssh-access - MCP:
get_agent_ssh_access(name) - SSH ports: 2222-2262 (incrementing per agent).
System Agent Terminal
- Admin-only browser terminal for the system agent (
trinity-system). - Accessible via the System Agent page.
For Agents
Each agent container runs an SSH server and a PTY multiplexer. The browser terminal connects through the backend's WebSocket proxy -- agents do not need to expose ports directly. Mode switching restarts the PTY process inside the container without dropping the WebSocket connection.

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.

agent-terminal is an agent published in the GitHub repository Abilityai/trinity (496 stars, last pushed 4d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 400 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.
