Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00149 | $0.01790 |
| Opus 5 | $0.00075 | $0.00895 |
| Sonnet 5 | $0.00030 | $0.00358 |
| Haiku 4.5 | $0.00015 | $0.00179 |
Grade A, and why
seo-content-audit 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 12d 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.
This is a copy
92% identical to seo-content-audit — 6 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 194 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Content Audit
Inventory existing content, score it, and decide for each piece: keep, update, merge, redirect, or delete. Stack-agnostic. Works on blogs, marketing sites, knowledge bases, and product content.
When to use
- Inheriting a content library you did not create
- Diagnosing site-wide traffic decline
- Resolving cannibalization (two pages competing for the same query)
- Pre-migration cleanup
- Annual or semi-annual content health check
- Pruning before a redesign or replatform
When NOT to use
- Optimizing a single page (use
seo-onpage) - Planning new content (use
seo-keyword) - Comparing your content to competitors (use
seo-competitor) - Site-level technical issues (use
seo-technical)
Required inputs
- The site URL and access to crawl it (or a complete URL list)
- Search console access (or a 12-month export)
- Analytics access (sessions, conversions, engagement)
- A backlink tool (to identify pages with referring domains worth preserving)
The framework: 5 actions
For every content piece, the audit produces one of five decisions.
1. Keep
The page performs well, has clear intent, and needs no changes.
Signals:
- Top 10 ranking for its primary query
- Consistent traffic with no decay
- Healthy engagement (above-site-average time on page or interaction rate)
- Up-to-date information
2. Update
The page has potential but is underperforming due to fixable issues.
Signals:
- Page 2 ranking for high-value queries (rank 11 to 30)
- Traffic decay over the last 6 to 12 months
- Information gone stale
- Title or meta need rewriting for CTR
- Thin content that could expand to match competitor depth
- Missing schema or other technical hygiene
3. Merge
Two or more pages target overlapping queries and should consolidate.
Signals:
- Cannibalization (multiple pages ranking for the same query, none ranking well)
- Significant content overlap between pages
- Combined, they would outperform either alone
- Both have backlinks worth preserving
What ships with it
2 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.
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.
