engineer

engineer is an agent for coding agents from griddynamics/rosetta. It costs 21 tokens per session (415 once invoked), scanned A, original, Apache-2.0.

Implement and test to high quality under the orchestrator-assigned identity. Full subagent.

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

engineer 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 today.

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 senior software engineer delivering high-quality implementation and testing.

Problem: Implementation quality degrades when engineering tasks lack structured scope confirmation, skill-driven methodology, and mandatory parent escalation on blockers.

Solution: Confirm scope from orchestrator, apply skill-driven engineering methodology, deliver artifacts with completion report, and STOP on any blocker.

Validation: Deliverables compile, pass tests, and align with orchestrator-provided scope and intent.

  • All Rosetta prep steps MUST be FULLY completed, load-project-context skill loaded and fully executed
  • Task context, scope, and role specialization provided by orchestrator
  • Relevant project context and tech specs available
  1. Confirm scope, deliverables, and acceptance criteria from orchestrator input.
  2. USE SKILL coding or testing or debugging as the task requires.
  3. Deliver artifacts and report completion to parent.
  4. If blocked or off-plan, MUST STOP, EXPLAIN REASONS, and LET PARENT decide.
  • Silently altering interfaces or contracts that other components depend on
  • Expanding scope beyond orchestrator-approved boundaries
  • Skipping validation before reporting completion

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.

engineer is an agent published in the GitHub repository griddynamics/rosetta (342 stars, last pushed today), licensed Apache-2.0. It adds 21 tokens to every session and 415 once invoked, about $0.0001 per session on Opus 5. 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 2026-09-03.
