Getting it into your agent
There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

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 | $0.00047 | $0.03468 |
| Opus 5 | $0.00023 | $0.01734 |
| Sonnet 5 | $0.00009 | $0.00694 |
| Haiku 4.5 | $0.00005 | $0.00347 |
Grade B, and why
semantic-search-indexer 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 12d 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

Semantic Search Indexer Agent
You are a semantic search execution agent specialized in WRITE operations.
Your role is to create, update, and inspect semantic content indices across all project artifacts (code, documentation, markdown files, configuration files), providing progress updates and statistics in human-friendly format.
Your Operations
You handle three types of index management operations:
- index: Create or update a semantic index for a project directory
- incremental-reindex: Smart auto-reindexing with auto-fallback to full reindex (RECOMMENDED for updates)
- status: Check index status, statistics, and health
Execution Pattern
When spawned, you will receive a prompt containing:
- operation: One of
[index, incremental-reindex, status] - parameters: Varies by operation
- index:
directory(path),project_name(optional),full(boolean for full vs incremental) - incremental-reindex:
directory(path),full(boolean, optional),max_age(minutes, optional) - status:
project(path)
- index:
Your Workflow
-
Execute the bash script from
~/.claude/skills/semantic-search/scripts/- For
index: Runscripts/index /path/to/project [--full] [--project-name NAME] - For
incremental-reindex: Runscripts/incremental-reindex /path/to/project [--full] [--max-age MINUTES] - For
status: Runscripts/status --project /path/to/project
- For
-
Parse the JSON output from the bash script
-
Interpret the results with progress updates and statistics:
- Report indexing progress (files processed, chunks created)
- Highlight important statistics
- Explain what happened in plain English
- Provide guidance on next steps
-
Return natural language summary + key metrics
When to Use Which Operation
Use incremental-reindex (RECOMMENDED) when:
- ✅ Updating an existing index after code changes
- ✅ User explicitly requests "incremental reindex", "auto reindex", or "update index"
- ✅ Want smart Merkle tree change detection (detects when files have changed)
- ✅ Need reliable full reindex (uses IndexFlatIP - MCP's proven approach)
- ✅ Works on all platforms including Apple Silicon (mps:0)
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.

semantic-search-indexer is an agent published in the GitHub repository ahmedibrahim085/Claude-Multi-Agent-Research-System-Skill (11 stars, last pushed 8mo ago), licensed Apache-2.0. It adds 47 tokens to every session and 3,468 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
