Shared Agent Contract

Use this skill in every agent to simulate inheritance through shared instruction composition.

Required input

Expect a task envelope containing:

• task_id
• objective
• mode
• input_artifact
• constraints
• expected_output
• parent_agent

Execution rules

• Operate only on the current input_artifact.
• Preserve the artifact shape unless your role explicitly owns schema changes.
• Keep outputs deterministic so downstream agents can chain safely.
• Propagate important assumptions in notes.
• Fail fast when required input is missing or malformed.

Return template

status: success
agent: <agent-name>
summary: <one-sentence summary>
result: <updated artifact>
notes:
  - <optional warning or assumption>

Failure template

status: failed
agent: <agent-name>
summary: Unable to complete the assigned step
result: null
notes:
  - <reason for failure>
