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 | $0.00058 | $0.00333 |
| Opus 5 | $0.00029 | $0.00167 |
| Sonnet 5 | $0.00012 | $0.00067 |
| Haiku 4.5 | $0.00006 | $0.00033 |
Grade A, and why
markdown-token-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 9d 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
Markdown Token Optimizer
This skill analyzes markdown files and suggests optimizations to reduce token consumption while maintaining clarity.
When to Use
- Optimize markdown files for token efficiency
- Reduce SKILL.md file size or check for bloat
- Make documentation more concise for AI consumption
Workflow
- Count - Calculate tokens (~4 chars = 1 token), report totals
- Scan - Find patterns: emojis, verbosity, duplication, large blocks
- Suggest - Table with location, issue, fix, savings estimate
- Summary - Current/potential/savings with top recommendations
See ANTI-PATTERNS.md for detection patterns and OPTIMIZATION-PATTERNS.md for techniques.
Rules
- Suggest only (no auto-modification)
- Preserve clarity in all optimizations
- SKILL.md target: <500 tokens, references: <1000 tokens
References
- OPTIMIZATION-PATTERNS.md - Optimization techniques
- ANTI-PATTERNS.md - Token-wasting patterns
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.

markdown-token-optimizer is a skill published in the GitHub repository Tyler-R-Kendrick/agent-skills (11 stars, last pushed 3mo ago), licensed MIT. It adds 58 tokens to every session and 333 once invoked, about $0.0003 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.
