Coding Agent

Coding Agent is a skill for Claude Code, Codex from notforyou23/home23. It costs 17 tokens per session (426 once invoked), scanned A, original, MIT.

A guide for deciding when coding work should be handed to a separate coding worker or runtime. It covers splitting work, assigning file ownership, defining success, and checking the result.

In plain words
What is it for?
Use it to plan feature builds, bounded refactors, and other implementation tasks that can be separated into clearly owned pieces.
Why use it?
It helps prevent vague or oversized handoffs, while avoiding delegation when a small task would be faster to do directly.

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

Coding Agent 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

Coding and delegation

Choose the route by the outcome and coordination cost. A capable model can handle a substantial change directly; file count alone is not a reason to delegate. Use independent agents for separable investigation, implementation, or review, not obligatory stages.

  • Direct work: enough context is already present and delegation would delay the critical path.
  • coding_run: a detached CLI coding session, with Git worktree/checkpoint options. Read coding jobs before launching or integrating one.
  • spawn_agent: a background Home23 run with shared identity and machine access, normally a fresh chat. Read subagents and workers for context, model selection, and lifecycle limits.
  • worker_run: a reusable configured worker with its own contract; inspect worker_list first.

Give the child the intended outcome, relevant facts and paths, owned files, existing work to preserve, authority and limits, and completion evidence. It may discover the cause itself. Keep briefing proportional; do not require an elaborate template or solve the task before delegating.

Remain responsible for the result. A launch or successful child message is not a finished parent task. Inspect relevant evidence, integrate within the original authorization, and check the resulting behavior. Preserve exact handles and avoid duplicate final delivery.

Changes

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.
