Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

syn-elasticsearch-reindex 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 8d 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

Elasticsearch: reindexing and zero-downtime migration

When to use

Use this skill for reindexing and zero-downtime migration in Elasticsearch. This skill specifically handles reindexing and zero-downtime migration and nothing else in the Elasticsearch family.

Procedure

Use the reindex API with aliases to migrate data to a new mapping, throttle reindex, and cut over with zero downtime.

Notes

This is the Elasticsearch skill dedicated to reindexing and zero-downtime migration. Sibling skills cover other Elasticsearch capabilities; this one is the right choice only when the task is about reindexing and zero-downtime migration.

Changes

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.
