Individual skill
context-crusher
Compress tool outputs, logs, and JSON before they enter the context window — structural compression via a deterministic stdlib script (schema + samples + stats instead of 300 raw rows), no API, no summarization loss. Use when asked shrink this tool output, my context is full of JSON, compress these logs before analysis, or stop wasting tokens on raw data. Produces the crushed artifact with its token math shown, the crush-or-keep decision rules, and the fetch-the-original escape hatch.

# Context Crusher Skill
The most expensive tokens in agent work are the ones nobody reads: 300 identical JSON rows when the schema plus three samples would do, a log where one error hides among four hundred heartbeats, a file pasted whole for one relevant section. This skill crushes those *structurally* — schema + head/tail samples + numeric stats for JSON arrays, dedupe-with-counts plus guaranteed error-line survival for logs, head/tail windowing for text — with a deterministic stdlib script, no model call, no summarization risk. The information that defines meaning survives; the repetition that defines cost doesn't.
## What This Skill Produces
- **The crushed artifact** — the compressed version, with its token math in the header (~6,000 → ~130 is typical for uniform JSON)
- **The crush decision** — what to crush, what to keep raw, and what to *link instead of load*
- **The escape hatch** — every crush names how to fetch the original when a detail turns out to matter
- **The pipeline habit** — where in the agent's workflow the crush step belongs (between tool and context, always)
