tscodesearch AGENTS.md

Repository instructions for Microsoft’s TypeScript code-search project, including preferred GitHub workflows and troubleshooting notes for its indexer.

In plain words
What is it for?
Handling GitHub issues and pull requests, configuring the indexer, restarting it, and inspecting real-time CSV logs.
Why use it?
It tells agents how to work with the repository and how to investigate repeated indexing by enabling CSV debug logs.

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.

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

tscodesearch AGENTS.md scanned grade A 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 yesterday.

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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 418 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Agent notes

This is the canonical instructions file for repository guidance. Put all long-form agent instructions in AGENTS.md. CLAUDE.md is a placeholder that points here.

Operational notes for agents working in this repo are maintained below.

GitHub workflow preference

This repository is hosted on GitHub. When working with pull requests, comments, checks, issues, and repository metadata, prefer GitHub-native tooling (for example, GH CLI and available GitHub-integrated tools) whenever possible.

Debugging the indexer: real-time CSV logs

When something goes wrong on the indexer side (the classic symptom: files get re-indexed on every restart even though the index already contains them), turn on the CSV debug log.

Enable

Set csv_debug in config.json:

{
  "port": 8108,
  "csv_debug": true,
  "roots": { "default": { "path": "q:/spocore/src" } }
}

Then node ts.mjs restart (or ts restart if the cmd is on PATH).

Accepted values:

value effect
false / "" / unset off
true / "1" / "on" / "true" logs to <repo>/.tantivy_csv/
any other string treated as an explicit directory path -- logs land there

Logging is opt-in and append-only; rows from successive restarts share a file and are distinguished by the per-row pid column.

CSV files

Written by indexserver/debug_logger.py, one file per event type. Each row starts with ts (ms-precision local time) and pid.

file rows are written when useful columns
session.csv daemon start/stop action = start/stop
backend_export.csv verifier exports the index map at scan start (once per session) doc_id, mtime, relative_path
fs_walk.csv every file the verifier walks against the exported map decision = matched / missing / stale
orphan.csv index entries with no matching file on disk (about to be deleted) doc_id
enqueue.csv every IndexQueue.enqueue (including dedup hits) action, reason, is_new
parse.csv every tree-sitter parse the queue worker runs parse_ms, ok, error
commit.csv every Tantivy commit, success or failure duration_ms, success, error
watcher.csv every watchdog event src_path, action

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.
