Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00037 | $0.00967 |
| Opus 5.5 | $0.00015 | $0.00387 |
| Sonnet 5.5 | $0.00007 | $0.00193 |
| Haiku 4.5 | $0.00004 | $0.00097 |
Grade B, and why
strategic-compact scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Strategic Compact Skill
Suggests manual /compact at strategic points rather than relying on arbitrary auto-compaction.
Why Strategic Compaction?
Auto-compaction triggers at arbitrary points:
- Often mid-task, losing important context
- No awareness of logical task boundaries
- Can interrupt complex multi-step operations
Strategic compaction at logical boundaries:
- After exploration, before execution — Compact research, keep plan
- After completing a milestone — Fresh start for next phase
- Before major context shifts — Clear old context before different task
Focus-Aware Compaction (inspired by OpenClaw)
Blind compaction = blind discards. Focus-directed compaction = preserving key information.
Usage: Specify what to preserve when manually compacting.
Scenario: Completed 3 hours of debugging, now starting a new feature
✅ /compact preserve root cause analysis and fix approach, discard trial-and-error debugging
❌ /compact (blind compaction may discard root cause analysis)
Common focus templates:
| Scenario | Focus Directive |
|---|---|
| After debugging | Preserve root cause and fix approach, discard trial-and-error |
| After planning | Preserve final plan and key decisions, discard alternative discussions |
| After code review | Preserve items to change, discard confirmed-OK sections |
| After strategy discussion | Preserve strategic decisions and metrics, discard brainstorming process |
| After multi-file edits | Preserve which files changed and why, discard file content details |
When to Trigger Compaction
| Signal | Action |
|---|---|
| Completed a full milestone | ✅ Good time to compact |
| Switching from exploration to execution | ✅ Good time to compact |
| Debugging complete, starting new feature | ✅ Good time to compact |
| In the middle of multi-step implementation | ❌ Do NOT compact |
| Still analyzing a problem | ❌ Do NOT compact |
/ctx shows 60-70% consumed |
🟡 Consider compacting |
/ctx observes ≥80% pressure |
Save the current Lane, compact if supported, verify and continue |
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

strategic-compact is a skill published in the GitHub repository myths-labs/muse (36 stars, last pushed 3d ago), licensed MIT. It adds 37 tokens to every session and 967 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
