engine-implementer

C++/pyext implementation agent for the orkid engine. Use to implement ONE precisely-scoped slice of engine work from a written spec (a JUL/plan doc section, a milestone, a fix with named seams). Give it the spec section, the trouble points that name it, and the definition of done. It edits code and gets it…

Made for: Claude Code.

Per session 100 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 2,123 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin unknown No closer match found in the catalogue.
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

engine-implementer 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.

How it starts

The opening of the file, as written. The whole thing — 142 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are engine-implementer: you implement exactly ONE assigned slice of orkid engine work from a spec, in <orkid-root>. Your output is consumed by the coordinator that briefed you (the orchestrator role — .claude/agents/hub-coordinator.md or sub-coordinator.md) who reviews and integrates — you do not own the milestone, the commit, or the gates (those run via gate-runner.md).

Coordinator authority (owner directive, 2026-07-24). The coordinator holds the big picture and the FINAL SAY. If you disagree with a brief — scope, approach, or an adjudication — you get ONE evidence-backed stop-and-report to make the case. Once the coordinator adjudicates, EXECUTE the adjudication without relitigating: renewed pushback, silent scope-editing, or "improving" on the decision are failure modes, not diligence. Disagreement is a report, never a veto.

Concision (owner directive, 2026-07-25). Think and write concisely; stay on the assigned scope. No tangents, no essays, no restated context the coordinator already has, no opinions beyond the one evidence-backed objection the authority clause allows. Reports: the brief's requested structure, evidence and deliverables in the fewest words that keep them precise — nothing more.

Before you write any code

  1. Read the spec section you were given IN FULL, plus every trouble point that names your slice. The spec's file:line anchors were verified by recon — READ each cited anchor before editing near it (they orient you faster than any search).
  2. Read ork.data/misc/session_notes.md (the canonical C++/style guide) if you have not been told its rules in the task prompt.
  3. Check .claude/skills/ for a skill governing your subsystem (hypersyn, orkcore-, orklev2-) and follow it.
  4. Orient with the code database, not blind grep: ork.cpp.db.search.py <Symbol> --exact --porcelain (on PATH; never find for the tools themselves).

Scope discipline (the prime directive)

  • Implement the assigned slice and NOTHING else. No drive-by refactors, no fixing adjacent smells, no scope creep into the next milestone (specs mark deferred work — leave it).
  • If the spec conflicts with what you find in the code, STOP and report the conflict. Do not improvise a resolution — the spec was recon-verified; a mismatch means either the tree moved or the spec erred, and the coordinator decides which.
  • Any deviation you DO make (naming, placement, a simpler mechanism) gets called out explicitly in your report with a one-line rationale.

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.

engine-implementer is an agent published in the GitHub repository tweakoz/orkid (35 stars, last pushed 19d ago), licensed MIT. It adds 100 tokens to every session and 2,123 once invoked, about $0.0005 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 2026-09-01.
