configuration-logging

configuration-logging is a skill for Codex from greenpau/caddy-security. It costs 36 tokens per session (2,867 once invoked), scanned A, original, Apache-2.0.

A configuration guide for filtering diagnostic messages from the AuthCrunch security component and safely redacting credentials in Caddy logs. It does not control authentication decisions or the separate Caddy authentication logger.

In plain words
What is it for?
Use it to add message or component skip rules and to configure safe credential-related diagnostics in a Caddy security setup.
Why use it?
It helps reduce unwanted security diagnostics without hiding returned errors, redirects, or access denials. It also makes clear which logger a setting actually affects.

Skill for Codex

About the project

caddy-security is a security application and set of plugins for Caddy v2, a web server, that handles user authentication and controls access to HTTP requests. It supports methods including local, LDAP, OpenID Connect, OAuth 2.0, SAML, JWT, and PASETO, and is used to protect web services behind Caddy.

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

configuration-logging 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 today.

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.

How it starts

The opening of the file, as written. The whole thing — 247 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Configuration Logging

Supported Scope

The root security logging block configures AuthCrunch component diagnostics. The selected Caddy's independent http.handlers.authentication logger remains unfiltered. Issue #280 is not fixed by this adapter. Read the host boundary below before recommending the issue's message/error patterns to an operator. Current authorize Caddyfiles use http.handlers.authorization; the legacy JSON authentication-provider chain is still supported and emits the host error. Do not change that chain's behavior to silence it.

The selected AuthCrunch module supplies Config.Logging, pkg/logging, the shared parser, and root logger wrapping. No local replacement or library release is needed for these interfaces. Recheck go list -m -json when dependencies change; the dependency workflow owns selection changes. Sibling source and skills remain read-only references.

Configuration

Inside the global options block:

{
	security {
		logging {
			skip exact text "token validation error"
		}
	}
}

This suppresses the AuthCrunch gatekeeper's diagnostic message; it leaves its returned errors, HTTP denial, redirects and authorization decisions unchanged. Other security declarations and site routes are configured normally.

The complete body grammar is one statement per line:

skip <exact|partial|prefix|suffix|regex> text <value>

Every statement has four tokens. Quote multiword values. Repeated rules, including identical rules and imported rule bodies, append in order and match with OR. Duplicate logging blocks, header arguments, nested blocks, empty tokens, malformed keywords/arity, invalid regular expressions, whitespace-only text and raw newlines are rejected with location-aware errors. Omission or an empty multiline block suppresses nothing; there are no implicit rules. The enclosing global security option also occurs once; repeating it fails instead of silently replacing the earlier app and discarding its rules.

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.
