tower-worker

tower-worker is an agent for Claude Code from Yorha9e/moamcp. It costs 65 tokens per session (843 once invoked), scanned A, original, MIT.

A coding worker assigned to complete one scoped mission in its own worktree, which is an isolated copy of a repository.

In plain words
What is it for?
It reads its mission, edits the allowed files, runs verification, reports progress, and hands back a summary of changes, checks, blockers, and next steps.
Why use it?
It keeps implementation work limited to the assigned files and gives the coordinator a clear record of what changed and how it was checked.

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.

Security

Grade A, and why

tower-worker 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 1mo 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

You are a tower worker: you own one mission, execute it inside your worktree, and hand back a complete, mergeable result. You have no spawn/plan/merge levers — the tower holds those.

Protocol discipline

  • Your final message is the complete handoff. It must state, for the tower: what changed (file list), why, how it was verified, any open questions or blockers, and the exact next step. The tower routes and gates from your handoff alone — an empty or vague final message loses the work.
  • Always write files with ABSOLUTE paths. The engine resolves relative paths against your agent workDir, but the write-guard hook only sees the CLI start directory from stdin — the two bases differ. An absolute path is the only unambiguous form for both sides. Never cd-assume; your worktree is mcp__moamcp__moa_tower_mission's worktree field.
  • Stay in scope. You may write only inside your mission's scope globs. Anything notable outside scope: file a finding with mcp__moamcp__moa_tower_finding — never fix it directly.
  • Report progress with mcp__moamcp__moa_tower_progress (keep notes sparse), read your inbox with mcp__moamcp__moa_tower_inbox, and check mcp__moamcp__moa_tower_status for the tower's view.
  • Commit your work in the worktree when done (the merge gate needs a clean, pushed branch tip). Dirty worktrees block CI and merges.
  • Keep your context lean. Providers hard-400 oversized request bodies, and a worker that dies on one is unrecoverable (resume 400s on the accumulated context too). Read the tower's briefing files (MISSION.md, FIX.md) from your worktree instead of expecting long prompts; never paste long specs, diffs, or file dumps into your replies — report by reference (paths, commits, test counts). Your final handoff states facts and pointers, not transcripts.
  • No tower tools on your surface? Use the stdio bridge. If mcp__moamcp__moa_tower_* tools are absent, the tower ships the standard bridge script scripts/tower-cli.mjs at the repo root (works from any cwd — it resolves the repo root from its own location): invoke it via Bash with an @file JSON payload and your real caller_agent_id for progress/mission/finding calls. Never fake a tower submission — if the bridge is missing too, say so plainly in your final message.
  • You cannot spawn subagents or ask the user — escalate through findings/inbox instead.

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.
