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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Output Handling · line 111 Output size or generation rate is not bounded. Unbounded output enables denial-of-service through resource exhaustion, log flooding, or context-window stuffing.Fix: Set explicit limits on output length, generation count, and rate. Use max_tokens and truncation to prevent unbounded output.
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 5.1 | $0.00067 | $0.02903 |
| Opus 5.5 | $0.00027 | $0.01161 |
| Sonnet 5.5 | $0.00013 | $0.00581 |
| Haiku 4.5 | $0.00007 | $0.00290 |
Grade A, and why
memstack-seo-meta-tag-optimizer 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 1mo 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.

🏷️ Meta Tag Optimizer: Scanning and optimizing page meta tags...
Scans all pages for existing meta tags, identifies issues, and generates optimized replacements: titles, descriptions, Open Graph, canonical URLs, and robots directives.
Activation
When this skill activates, output:
🏷️ Meta Tag Optimizer, Scanning pages for meta tag issues...
Then execute the protocol below.
| Context | Status |
|---|---|
| User says "optimize meta tags" or "fix meta tags" | ACTIVE |
| User says "title tags" or "meta description" or "og tags" | ACTIVE |
| Improving SEO for specific pages | ACTIVE |
| Running a full site audit (broader scope) | DORMANT: use site-audit |
| Adding structured data / JSON-LD | DORMANT: use schema-markup |
Anti-patterns
| Trap | Reality Check |
|---|---|
| "Same meta description on every page" | Duplicate descriptions get ignored by Google. Each page needs unique, relevant meta. |
| "Title = just the page name" | "About" tells Google nothing. "About [Company] - [Key Differentiator]" ranks. |
| "OG tags are optional" | Without og:image, your shared links look broken on social. No image = no clicks. |
| "Canonical URLs don't matter" | Duplicate content splits ranking signals. Canonical tags consolidate authority to one URL. |
| "Longer titles rank better" | Google truncates after ~60 chars. Truncated titles look unprofessional and lose clicks. |
Protocol
Step 1: Scan All Pages
Identify every page and its current meta tags:
# Find all page/route files
find app/ pages/ src/ -name "*.tsx" -o -name "*.jsx" -o -name "*.html" 2>/dev/null | grep -v node_modules | grep -v "_\|layout\|loading\|error\|not-found"
# Next.js metadata exports
grep -rn "export const metadata\|export function generateMetadata" --include="*.tsx" --include="*.ts" . | grep -v node_modules
# Check for global/shared metadata
cat app/layout.tsx 2>/dev/null | head -30
Build the page inventory:
| Page | Route | Has Title | Has Description | Has OG | Has Canonical |
|---|---|---|---|---|---|
| Homepage | / |
? | ? | ? | ? |
| About | /about |
? | ? | ? | ? |
| Pricing | /pricing |
? | ? | ? | ? |
| Blog index | /blog |
? | ? | ? | ? |
| Blog post | /blog/[slug] |
? | ? | ? | ? |
| ... | ... | ... | ... | ... | ... |
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.
