Context Engineering Planner

Use this skill when an agent workflow needs deliberate context design instead of a large undifferentiated prompt.

Plan

• Identify the decision the agent must make and the evidence it needs.
• Split context into durable source, transient working context, generated evidence, and memory candidates.
• Prefer repo files, issues, manifests, tests, traces, and docs over prose recollection.
• Define what may be retrieved automatically and what must be explicitly requested.
• Define what should be compressed, summarized, or excluded.
• Name stale-context risks and refresh checks.

Context Classes

• source: canonical specs, code, issues, policies, manifests
• evidence: tests, logs, screenshots, traces, evaluation results
• memory: reusable lessons worth recording with the project memory mechanism
• working: temporary notes used only for the current run
• excluded: secrets, private data, raw traces, irrelevant history, stale generated output
