XERJ is a local search tool that automatically indexes folders so coding agents can retrieve relevant code, documents, logs, and PDFs without reading files one at a time. It is for developers and agents using code search, retrieval-augmented generation, security audits, or agent memory.
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 | $0.00029 | $0.00305 |
| Opus 5.5 | $0.00012 | $0.00122 |
| Sonnet 5.5 | $0.00006 | $0.00061 |
| Haiku 4.5 | $0.00003 | $0.00030 |
Grade A, and why
index 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 5d 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
Index the folder $1 with XERJ so its documents can be searched.
- Choose the prefix: use
$2if it was given, otherwise a short lowercase name derived from the folder name (letters, digits and dashes only). - Run
xerj autoindex "$1" --prefix <prefix>and wait for it to finish. Re-runs are incremental, so this is also how to pick up changed files later. If it stops with exit code 4 and prints a JSON list of plans, the full folder would not fit the node's disk. Show the user the plans and ask which one to use before re-running with--yes(the recommended plan) or--plan <name>. Never pass--drop-indexedwithout asking: it confirms deleting already-indexed data. - Report how many files were indexed and any files that were skipped and why,
as printed by the command. Tell the user the prefix to search with:
/xerj-knowledge:find <question>.
If xerj is not installed or no node is running, do not try to work around it:
show the install and start steps from the plugin README.
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.

index is a command published in the GitHub repository xerj-org/xerj (19,064 stars, last pushed today), licensed Apache-2.0. It adds 29 tokens to every session and 305 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-11-01.
