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 | $0.00028 | $0.00312 |
| Opus 5 | $0.00014 | $0.00156 |
| Sonnet 5 | $0.00006 | $0.00062 |
| Haiku 4.5 | $0.00003 | $0.00031 |
Grade A, and why
strategic-compact scanned grade A with 0 findings 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 6d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Strategic Compact
Guide for managing context window compaction without losing critical information.
When to Activate
- When edit count reaches threshold (tracked by suggest-compact.js hook)
- Before manual
/compactinvocation - When PreCompact hook fires
Preservation Checklist
Before any compaction, ensure these are preserved (written to session state or mentioned in compact summary):
- Current tasks — what is being worked on right now, including task IDs
- Changed files — list of files modified in this session and why
- Unresolved issues — blockers, open questions, pending decisions
- Architecture decisions — choices made during this session with rationale
- User feedback — corrections, preferences, or approach changes the user requested
Compaction Timing
The suggest-compact.js hook tracks edit count via a temp file:
- 15 edits: first suggestion ("Consider compacting to preserve context")
- 30 edits: stronger suggestion
- Every 15 edits thereafter: repeated suggestion
PreCompact Behavior
When PreCompact fires, the hook should:
- Read current session state from
~/.claude/sessions/ - Output preservation checklist items to stderr as reminders
- Save a snapshot to the session file before compaction proceeds
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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 OkminLee/everything-claude-code-ios (58 stars, last pushed 5mo ago), licensed MIT. It adds 28 tokens to every session and 312 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
