feat(ce-plan): reduce token usage by extracting conditional references#489
Conversation
…vings Extract three large conditional/late-sequence blocks from ce:plan SKILL.md into on-demand reference files, reducing the base skill from 1,023 lines (~15,525 tokens) to 685 lines (~9,971 tokens) — a 36% reduction. For orchestration-heavy skills like ce:plan with 20-40+ tool/agent calls per session, unused content carried in every message exchange compounds significantly. This saves ~130,000-167,000 context tokens per planning session depending on which code paths execute. Extracted files: - references/deepening-workflow.md (5.3.3-5.3.7, ~3,808 tok) — loaded only when the deepening gate passes - references/visual-communication.md (4.4, ~823 tok) — loaded only when plan has complex visual-worthy content patterns - references/plan-handoff.md (5.3.8-5.4, ~1,304 tok) — loaded only at end of workflow for document review and post-generation options Also adds a "Conditional and Late-Sequence Extraction" rule to the plugin AGENTS.md to guide future skill optimization.

The 4.4 stub was missing the Key Technical Decisions and Alternative Approaches triggers. Restores the complete condition set so the agent loads visual-communication.md for all cases the reference file covers. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Summary
Token savings evidence
ce:plan is an orchestration-heavy skill that makes 20-40+ tool/agent calls per session. Every message exchange carries the full SKILL.md in context. Extracting unused content eliminates that compounding cost:
references/deepening-workflow.mdreferences/visual-communication.mdreferences/plan-handoff.mdPer-session savings: ~130,000-167,000 context tokens (extracted tokens x messages before they're needed).
Validation
Ran 3 test plans exercising all code paths:
Zero premature reference file reads across all tests. All 582 unit tests pass.
