Implement

Read and follow the shared delegation protocol
before launching any session. This skill is manually invoked; treat the user's
arguments as the implementation assignment and as authoritative instructions
about scope, models, session count, and ownership.

Defaults

• Model: openai-codex/gpt-5.6-sol
• Thinking: medium
• Sessions: one, unless the work separates cleanly into non-overlapping pieces
• Name pattern: impl-<topic>

When launching multiple implementers, assign non-overlapping files or pieces so
they cannot overwrite one another. If ownership cannot be divided cleanly, use
one session.

Brief

In addition to the shared briefing contract, specify:

• the exact behavior to implement
• files the session owns and files it must not touch
• structural and compatibility constraints
• verification commands and acceptance criteria
• that it must report files changed and verification results

Completion

Inspect every changed file and review the combined diff yourself. Run the
required verification before reporting completion. Do not treat a spawned
session's success claim as sufficient evidence.
