/strategic-compact — Smart Context Management
Identifies the optimal moment to run /compact based on your current workflow state. Proactive compaction prevents quality degradation that happens when context fills up.
Usage
/strategic-compact # Analyze and suggest
/strategic-compact now # Compact immediately with state preservation
When to Compact
Good Times (Low Risk)
- After planning is complete — exploration clutter no longer needed
- After a commit — implementation context can be summarized
- After switching tasks — previous task context is stale
- After a long research phase — findings are in files, not just in context
- When token-warning fires — 70%+ usage, quality starts degrading
Bad Times (High Risk)
- Mid-implementation — lose track of what you're building
- During debugging — lose the error context and investigation trail
- Before committing — lose track of what changed and why
- While waiting for test results — lose context for interpreting results
State Preservation
Before compacting, the skill ensures critical state is saved:
- Current task context — What are we working on?
- Key decisions made — Architecture choices, approach decisions
- Files modified — What was changed in this session
- Pending actions — What still needs to be done
- Known issues — Problems encountered, workarounds applied
This state is passed to /compact as additional context for the summary.
Workflow Integration
The ideal development cycle:
1. Plan (explore, research, design)
2. /strategic-compact → clear exploration clutter
3. Implement (write code, tests)
4. Commit
5. /strategic-compact → clear implementation details
6. Next task
Output Format
## Compaction Analysis
**Recommendation:** COMPACT NOW
**Reason:** Planning phase complete (47 tool calls since last compact).
Implementation context is 34% of budget. Exploration results are in
STATUS.md — safe to compact.
**State to preserve:**
- Working on: ECC Phase 2 integration
- Last commit: feat(skills): add verification-loop
- Next: Create context-budget skill
- Key decision: Using skill format, not command format
**Command:** /compact
Compaction Loop Cap
To prevent infinite compact-work-compact cycles that indicate the task is too large for a single session, strategic-compact enforces a maximum of 3 compactions per session.
How It Works
The skill tracks compaction count internally. On each invocation:
- Count < 3 — Proceed normally with compaction analysis and execution
- Count = 3 — Issue a warning and block further compaction:
## Compaction Limit Reached
You have compacted 3 times this session. This indicates context is being
consumed faster than expected.
**Recommended actions:**
1. Break the current task into smaller, independently completable sub-tasks
2. Commit current progress and start a fresh session for the next sub-task
3. Use /handoff to preserve context for the next session
Further compaction is blocked to prevent quality degradation from
repeated context loss.
Why This Matters
Each compaction loses nuance — decisions, investigation trails, and subtle context that summaries cannot fully preserve. After 3 compactions, the accumulated loss significantly impacts quality. It is better to commit progress and start fresh than to continue with degraded context. Reference: oh-my-opencode v3.16.0 added a similar cap to prevent infinite compaction cycles.
Inspired by ECC's strategic-compaction skill and GSD v2's fresh-context-per-task concept.
Post-Compact Recovery: /recap
After compaction, use /recap (Claude Code v2.1.108+) for quick context recovery instead of re-reading all files. /recap generates a focused summary of what was happening before compaction — faster than /handoff read and more targeted than re-reading STATUS.md.
Flow: /strategic-compact now → compaction happens → /recap → resume work with context.
Tiered Context Injection
For projects with large context requirements, consider GSD v2's tiered context injection pattern (v2.67.0+) which achieves 65%+ context reduction by loading context in tiers:
- Always loaded — Project identity, active phase, critical decisions
- On-demand — File-level details, implementation specifics
- Never loaded — Completed phases, archived decisions
This pattern complements strategic-compact: instead of compacting everything, inject only the tier relevant to the current task. Reference: GSD v2 Decision Scope Cascade.
