What is semantic-search-reindex?

A command that rebuilds the semantic-search index for a codebase. The index is the stored data that lets semantic search find related code by meaning.

Use it to start a full reindex, optionally clear the old index first, and check the initial background progress.

It refreshes search data when the codebase has changed or the existing index is outdated.

When invoked 134 The whole file, excluding the scripts and references it only reads on demand.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00012	$0.00134
Opus 5.5	$0.00005	$0.00054
Sonnet 5.5	$0.00002	$0.00027
Haiku 4.5	$0.00001	$0.00013

Security

Grade A, and why

semantic-search-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 2mo 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

Semantic Search Reindex

Trigger a full reindex of the codebase for semantic search.

Action

Call mcp__semantic-search__reindex tool with force: true
Immediately call mcp__semantic-search__get_status to show initial progress
Inform the user that indexing is running in the background
Tell them they can check progress with /semantic-search:status

Options

If the user says "clean" or "fresh", use clear_first: true to wipe the index before rebuilding.

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.
