What is ddx-term-mcp-specialist?

A coding assistant for the ddx-term-mcp package, which lets an agent communicate with a shared tmux terminal session. It covers the server, terminal commands, screen reading, and publishing setup.

Use it when changing files under ddx-term-mcp/src or its publishing configuration, including terminal sessions, command handling, screen snapshots, and the bundled release.

It keeps terminal-related changes in one place and preserves the package’s rules, such as using a simple command runner instead of a pseudo-terminal.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00082	$0.00869
Opus 5.5	$0.00033	$0.00348
Sonnet 5.5	$0.00016	$0.00174
Haiku 4.5	$0.00008	$0.00087

Security

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 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.

Runs shell commandslowCapability

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.md if it exists.
Read context/agents/ddx-term-mcp-specialist_extra_learned_instructions.md if it exists.
Read ddx-term-mcp/CLAUDE.md and context/_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 + CallTool handlers.
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-contract via noExternal).

Load-bearing invariants (NEVER violate)

NO PTY — no node-pty, no pty.spawn, no raw-shell child_process. tmux only. no-pty.spec.ts greps the source and MUST stay green.
term_send: send-keys -l <text> (LITERAL) + a SEPARATE Enter event. NEVER \n. Control keys → term_signal, never term_send.
term_snapshot = visible viewport (capture-pane -p WITHOUT -S). term_read = scrollback delta via per-terminalId read-cursor, capped by DDX_TERM_MAX_READ_LINES.
Address by terminalId; term_signal(pid) validates pid ∈ the terminal's process tree.
Never exceed DDX_TERM_MAX_TERMINALS; never target a session ≠ $DDX_TERM_SESSION.
All input schemas from @ddx/term-contract (TERM_TOOL_INPUT_SCHEMAS). Zero any.

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.
