frigg-first-code-search

frigg-first-code-search is a skill for Claude Code, Codex from bnomei/frigg. It costs 0 tokens per session (28 once invoked), scanned A, original, MIT.

A code-search helper that prefers Frigg, a system for searching indexed source code, and uses result handles and match reading for evidence.

In plain words
What is it for?
Searching indexed code and inspecting matching source as proof.
Why use it?
It helps locate source code and check the exact matches found. The limited description does not say how it handles other search methods.

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

frigg-first-code-search 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

frigg-first-code-search (dogfood fixture stub)

Prefer Frigg MCP for indexed source. result_handle + read_match for proof.

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.

frigg-first-code-search is a skill published in the GitHub repository bnomei/frigg (5 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 28 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.
