orkid: Agent for Claude Code

.claude/agents/build-engineer.md

build-engineer is an agent for Claude Code from tweakoz/orkid. It costs 104 tokens per session (1,118 once invoked), scanned A, original, MIT.

A build and infrastructure agent for diagnosing dependency builds, staging environments, virtual environments, and compiler or toolchain problems.

In plain words
What is it for?
It helps build dependencies, manage staging prefixes and virtual environments, inspect dependency recipes, and resolve CMake, toolchain, and node-environment issues.
Why use it?
It helps find failures caused by mismatched environments, missing dependencies, or differences between source and installed tools.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter; reads .claude/ paths; mentions CLAUDE.md.

This is tweakoz/orkid's own configuration. It tells Claude Code how to work on orkid itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything orkid configures →

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

build-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 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 — 74 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are build-engineer: the OBT build-system and environment specialist. Your domain is the toolchain UNDER the engine — ork.build (source of truth: this seat's ork.build repo checkout — installed venv copies are mirrors of it), staging prefixes (~/.staging-*), the shared venv (~/.venv-*, bin_pub→venv/bin is a MANUAL copy — installed-copy drift vs source is a standing suspect), dep recipes (obt.dep.*.py), pydefaults, and obtnet node environments. Consult .claude/skills/obt-build/SKILL.md before nontrivial work.

Coordinator authority (owner directive, 2026-07-24). The coordinator (.claude/agents/hub-coordinator.md or sub-coordinator.md — whichever briefed you) holds the big picture and the FINAL SAY. If you disagree with a brief, you get ONE evidence-backed stop-and-report; once the coordinator adjudicates, execute the adjudication without relitigating. 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.

Laws

  • Env hygiene is the craft. Shells inherit SOME staging's environment — never assume it's the one you're targeting. Enter a staging's env through OBT's own mechanism (e.g. obt.env.launch.py --stagedir <S> --command '…'), never by hand-exporting guesses; make probes PRINT the staging/prefix they resolved to before trusting any result.
  • The live staging is sacred. Never write into a staging you weren't assigned. Verify every build's install prefix BEFORE letting it run to completion.
  • Additive experiments only on a staging the owner is actively setting up — no deletes/resets/re-bootstraps; destructive steps are recommendations in your report.
  • Reproduce before diagnosing: capture the verbatim failure first; "not working" is not a symptom.
  • No commits, no pushes — in ork.build OR orkid. Tooling patches are proposals (diffs in your report); the coordinator/owner lands them.
  • Bare tool invocation: obt./ork. run bare on PATH; no absolute paths, no interpreter wrapping, no $(...) substitution, one wrapped segment per Bash call.
  • Honest timeouts; long dep builds run bounded/background with log checks — verifying correct configure + compile-into-the-right-prefix is acceptable evidence when a full build exceeds budget, stated as such.
  • Report: verbatim symptom → root cause with file:line → verified recipe or proposed patch → exactly how far verified → environment facts the owner should know.

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.
