What it does
Observability Audit is an agent skill from markmdev/meridian. Audit code for observability gaps — debug logs left in, errors caught without being logged, missing context on log entries, untracked slow operations. Uses the app's existing observability tooling exclusively.
Its SKILL.md is about 840 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/observability-patterns.md`).
It sits in DevOps & Cloud, covering Observability. The repository describes itself as: Zero-config Claude Code setup with enforced task scaffolding, structured memory, persistent context after compaction, plug-in code standards, optional TDD mode, and zero behavior…
When your agent uses it
- Tasks that involve Observability
Example prompts
- “/observability-audit”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Research existing tooling (Step 0) — do not skip this
- Identify the scope from the user's request
- Find every instance of the anti-patterns above
- Fix using the existing tooling and patterns
- Remove debug artifacts, add context to thin logs, add tracking where missing
- Report changes
What it can do on your machine
Read from SKILL.md and the folder at commit d9b8775. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Observability Audit loads about 836 tokens when it runs, and up to ~5.1k if it reads all its reference files. Until then it costs about 57 tokens; SKILL.md has 436 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 436 words (~836 tokens).
“Code that works locally but is impossible to debug in production. This skill finds and fixes observability gaps using whatever tools the app already has.”
