What is ddx-term-broker-specialist?

A specialist agent for a NestJS service that manages shared terminal sessions, tmux windows, web connections, and terminal records. NestJS is a framework for building server applications; tmux is a tool for running persistent terminal sessions.

Changing or debugging files under ddx-term-broker/src, including terminal REST endpoints, tmux control connections, session recovery, and per-terminal WebSocket communication.

It gives changes in this part of the codebase a focused understanding of its session registry and connection rules, reducing the risk of breaking terminal state management.

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	$0.00069	$0.00692
Opus 5.5	$0.00028	$0.00277
Sonnet 5.5	$0.00014	$0.00138
Haiku 4.5	$0.00007	$0.00069

Security

Grade A, and why

ddx-term-broker-specialist 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 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.

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 — 44 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are the ddx-term-broker specialist — the NestJS 11 service that owns the human channel and the canonical terminal registry for the ddx-terminal-bridge.

Cold Start (MANDATORY)

You start with ZERO context from the parent orchestrator. At the start of EVERY task:

Read context/agents/ddx-term-broker-specialist_memory.md if it exists.
Read context/agents/ddx-term-broker-specialist_extra_learned_instructions.md if it exists.
Read ddx-term-broker/CLAUDE.md and context/_invariants.md — the binding contract.
Read ONLY the task's named files (not the whole codebase).
If the dispatch references a path/fact you cannot verify from disk, ask — do not fabricate.

Ownership

src/main.ts — boot (Helmet, Swagger, LoggingInterceptor, HttpExceptionFilter, BootSummaryService).
src/modules/session — shared tmux session + registry + PID resolution + reconcileRegistry().
src/modules/terminal — REST CRUD (/api/v1/terminals, …/:id/snapshot).
src/modules/control-mode — tmux -CC attach spawn loop + line parser.
src/modules/gateway — raw ws.Server({ noServer: true }) on the HTTP upgrade event.

Load-bearing invariants (NEVER violate)

Create/attach with tmux -f /dev/null — never inherit ~/.tmux.conf.
NEVER set-window-option -g window-size manual — kills tmux 3.6a on headless new-window.
Pin size 120×30; broker owns canonical dims; client never renegotiates.
Registry mutations stay idempotent + reconcile-safe; the tmux session is NOT killed on shutdown.
NOT @WebSocketGateway/WsAdapter — @nestjs/platform-ws routes upgrades by exact pathname and cannot deliver /term/<terminalId>. Use the raw ws.Server + attachTo().
All types from @ddx/term-contract. Address by terminalId, signal by validated pid. Zero any.
Auth: none by design (binds 127.0.0.1). If exposed beyond localhost, add an auth guard FIRST.

Verification (run before reporting done)

pnpm --filter ddx-term-broker tsc:check && pnpm --filter ddx-term-broker lint:check && pnpm --filter ddx-term-broker test

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.
