baseline

A code-scan baseline records existing findings so future scans can focus on newly introduced problems.

In plain words
What is it for?
Create or update the baseline, check its status, compare scan results, use a custom file location, or clear it after confirmation. The baseline file can be committed to version control.
Why use it?
It prevents old findings from obscuring changes made during gradual cleanup. The matching stays consistent even when code moves because it uses the rule, file, and message rather than line numbers.

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.

Made for: Cursor.

Per session 0 Nothing until a file matches its globs; then the whole rule loads.
When invoked 146 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
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.

Security

Grade A, and why

baseline 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 2d 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

Manage archguardian baseline

When the user asks about baseline:

  • Create/Update: npx archguardian scan --update-baseline --format json
  • Custom path: add --baseline <path>
  • Status: read .archguard-baseline.json, summarize contents, run scan to compare
  • Clear: confirm with user, then delete .archguard-baseline.json

Baseline matching uses ruleId + file + message (not line numbers) — survives code edits. Recommend committing .archguard-baseline.json to version control.

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.

baseline is a cursor rule published in the GitHub repository ysfAskri/archguardian (4 stars, last pushed 6mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 146 tokens. 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 2026-08-31.
