Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 5.1 | $0.00083 | $0.00530 |
| Opus 5 | $0.00042 | $0.00265 |
| Sonnet 5 | $0.00017 | $0.00106 |
| Haiku 4.5 | $0.00008 | $0.00053 |
Grade A, and why
strata:audit-config scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
strata:audit-config
Anthropic's 2026 guidance on Claude Code in large codebases:
Teams should expect to do a meaningful configuration review every three to six months, but it's also worth doing one whenever performance feels like it's plateaued after major model releases.
Instructions optimized for older models can work against a future one.
This skill is the operational reminder. It walks your project's Claude Code
Config and reports items that haven't been touched in --stale-days (180 by
Default), so you can revisit them deliberately.
When to run
- Every 3–6 months as a scheduled habit
- After a major Claude model release (Anthropic-recommended)
- Before onboarding a new team to the codebase
- When Claude's behaviour starts feeling sluggish or off
How
# Default: 180-day staleness threshold
"${CLAUDE_PLUGIN_ROOT}/bin/strata" audit-config
# Tighter cadence
"${CLAUDE_PLUGIN_ROOT}/bin/strata" audit-config --stale-days 90
What it covers
| File / dir | Why it matters |
|---|---|
CLAUDE.md |
Loaded every session; conventions drift |
.claude/settings.json |
Team config; check enabled plugins are still relevant |
.claudeignore |
Exclusion rules go stale as the repo evolves |
.claude/skills/ |
Project-local skills — same drift risk |
.claude/agents/ |
Sub-agent definitions — same |
Read-only, never modifies. Output is a markdown report you can paste into a Review meeting.
Pairs well with
/strata:review— audits the vault (decisions, lessons, domain notes)/strata:audit-config— audits the project's Claude Code setup
Different surfaces. Run both on the same cadence.
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.

strata:audit-config is a skill published in the GitHub repository gideondk/strata (5 stars, last pushed 1mo ago), licensed MPL-2.0. It adds 83 tokens to every session and 530 once invoked, about $0.0004 per session on Opus 5. 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.
