What is fluentbit-validator?

A validator for Fluent Bit configuration files, which define how log data enters, is filtered, and is sent elsewhere.

Use it to lint, audit, or check classic-mode Fluent Bit files containing INPUT, FILTER, and OUTPUT sections. It reports static issues and, when available, validates the configuration by running Fluent Bit.

It catches configuration mistakes such as broken tag routing, mismatched inputs and outputs, and security problems before deployment. It can also perform a Fluent Bit dry run when the program is installed.

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.

Model	Per session	Once invoked
Fable 5	$0.00026	$0.01293
Opus 5	$0.00013	$0.00647
Sonnet 5	$0.00005	$0.00259
Haiku 4.5	$0.00003	$0.00129

Security

Grade A, and why

fluentbit-validator 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.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/validate_config.py, scripts/validate.sh, tests/test_validate_config.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 181 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Fluent Bit Validator

Use this skill to run deterministic, repeatable validation for Fluent Bit classic-mode configs.

Trigger Phrases

Use this skill when prompts look like:

"Validate this fluent-bit.conf before deploy"
"Lint my Fluent Bit config and report issues"
"Check tag routing and output matches in Fluent Bit"
"Run security checks for Fluent Bit config"
"Dry-run Fluent Bit config and tell me what failed"

Execution Model

Run steps in order. Do not skip Stage 0.

Stage 0: Precheck (Required)

Run from skill directory:

cd devops-skills-plugin/skills/fluentbit-validator

Check required and optional binaries:

command -v python3 >/dev/null 2>&1 && echo "python3: available" || echo "python3: missing"
command -v fluent-bit >/dev/null 2>&1 && echo "fluent-bit: available" || echo "fluent-bit: missing (dry-run will be skipped)"

Precheck protocol:

If python3 is missing: stop script-based validation, report blocker, and switch to manual config review only.
If fluent-bit is missing: continue static checks, skip dry-run, and record a Recommendation explaining skip reason and next step.

Stage 1: Static Validation (Required)

Default command:

python3 scripts/validate_config.py --file <config-file> --check all

Use targeted checks only when requested:

python3 scripts/validate_config.py --file <config-file> --check structure
python3 scripts/validate_config.py --file <config-file> --check sections
python3 scripts/validate_config.py --file <config-file> --check tags
python3 scripts/validate_config.py --file <config-file> --check security
python3 scripts/validate_config.py --file <config-file> --check performance
python3 scripts/validate_config.py --file <config-file> --check best-practices
python3 scripts/validate_config.py --file <config-file> --check dry-run

Strict CI gate (optional):

python3 scripts/validate_config.py --file <config-file> --check all --fail-on-warning

Files

What ships with it

11 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
