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 | $0.00102 | $0.00493 |
| Opus 5 | $0.00051 | $0.00246 |
| Sonnet 5 | $0.00020 | $0.00099 |
| Haiku 4.5 | $0.00010 | $0.00049 |
Grade A, and why
seo-toolkit 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 10d 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
SEO Toolkit — DEPRECATED (router)
This skill is deprecated. The 13 commands were split into four focused skills. Do not run the old 13-command workflow — load the matching sub-skill directly.
Routing table
| Need | Load this skill instead |
|---|---|
| Full technical audit, Core Web Vitals, scored report, autonomous fixes | seo-audit |
| JSON-LD schema.org, meta tags, Open Graph, Twitter Cards | seo-schema |
| Content quality, keywords, headings, image SEO | seo-content |
| Crawlability, internal linking, URL structure, competitors | seo-crawl |
The old command docs moved into the four new skills:
- seo-audit / seo-speed / seo-report / seo-fix →
seo-audit - seo-schema / seo-meta +
seo_schema.py(meta, jsonld) →seo-schema - seo-content / seo-keywords / seo-headings / seo-images +
seo_content.py(density) →seo-content - seo-crawl / seo-structure / seo-compare →
seo-crawl
Removal plan
Keep this router for one release cycle for backward compatibility, then delete.
What ships with it
4 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.

seo-toolkit is a skill published in the GitHub repository bestdeejay-design/agent-skills (5 stars, last pushed 3d ago), licensed MIT. It adds 102 tokens to every session and 493 once invoked, about $0.0005 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.

workflow
Use when a task is too large for turn-by-turn orchestration and should run through the big-task workflow lane: system-wide changes, large migrations, repo-wide audits, high-confidence verification, or tasks explicitly asking to run a workflow. Claude Code uses native dynamic workflows; Codex, OpenCode, and Grok use…
skill-compiler
Automatic solved-to-skill compiler — detects novel task completions and autonomously drafts new SKILL.md files. Stolen from Hermes Agent's learning loop (NousResearch, 2026-05-11).
context-compactor
9-section context compression with analysis scratchpad. Adapted from Claude Code's /compact system (2026-03-31).
daemon-loop
Autonomous recurring agent tasks — converts workflows into persistent background daemons that run on intervals. Stolen from Boris Cherny's Claude Code /loop pattern (2026-03-31).
trade-journal-analyzer
Unified post-trade analytics: journal pattern extraction + drawdown classification. Absorbs: drawdown-classifier.
Deep Research Loop
Multi-step web research, compilation, and synthesis workflow. Scrapes multiple sources, cross-references claims, and produces a structured research brief.
