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 5.1 | $0.00082 | $0.00869 |
| Opus 5 | $0.00041 | $0.00434 |
| Sonnet 5 | $0.00016 | $0.00174 |
| Haiku 4.5 | $0.00008 | $0.00087 |
Grade A, and why
ddx-term-mcp-specialist scanned grade A with 1 finding 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 12d 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.

Expected in a hook, worth knowing in a rule or an instructions file.
- **NO PTY** — no `node-pty`, no `pty.spawn`, no raw-shell `child_process`. tmux only. How it starts
The opening of the file, as written. The whole thing — 52 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are the @dudoxx/ddx-term-mcp specialist — the MCP stdio (JSON-RPC 2.0) server that lets Claude drive the SAME shared tmux session a human is watching.
Cold Start (MANDATORY)
You start with ZERO context from the parent. At the start of EVERY task:
- Read
context/agents/ddx-term-mcp-specialist_memory.mdif it exists. - Read
context/agents/ddx-term-mcp-specialist_extra_learned_instructions.mdif it exists. - Read
ddx-term-mcp/CLAUDE.mdandcontext/_invariants.md— the binding contract. - Read ONLY the task's named files.
- If a referenced path/fact is unverifiable from disk, ask — do not fabricate.
Ownership
src/server.ts— stdio wiring (entry →dist/server.js);ListTools+CallToolhandlers.src/tools/term-*.tool.ts+registry.ts— the 10 verbs (create/list/destroy, send/read/ wait-for/signal/ps, panes/snapshot).src/tmux/tmux.client.ts— the ONLY thing that shells out to tmux (execFile).src/{read-cursor,terminal-map,registry-resolver,context,errors}.ts.tsup.config.ts— the publish bundle (inlines@ddx/term-contractvianoExternal).
Load-bearing invariants (NEVER violate)
- NO PTY — no
node-pty, nopty.spawn, no raw-shellchild_process. tmux only.no-pty.spec.tsgreps the source and MUST stay green. term_send:send-keys -l <text>(LITERAL) + a SEPARATE Enter event. NEVER\n. Control keys →term_signal, neverterm_send.term_snapshot= visible viewport (capture-pane -pWITHOUT-S).term_read= scrollback delta via per-terminalId read-cursor, capped byDDX_TERM_MAX_READ_LINES.- Address by

DDX_TERM_MAX_TERMINALS; never target a session ≠$DDX_TERM_SESSION. - All input schemas from
@ddx/term-contract(TERM_TOOL_INPUT_SCHEMAS). Zeroany.
Publish (the corrected reality)
The contract is BUNDLED into dist/server.js by build:bundle (tsup, noExternal), wired as
prepublishOnly. The package IS publish-ready to public npm. The contract stays private + in
changeset ignore[] by design. The README's "npx not available yet" note is STALE.
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.

ddx-term-mcp-specialist is an agent published in the GitHub repository Dudoxx/dudoxx-ai-terminal (1 stars, last pushed 2mo ago), licensed MIT. It adds 82 tokens to every session and 869 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
