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 | $0.00000 | $0.00188 |
| Opus 5 | $0.00000 | $0.00094 |
| Sonnet 5 | $0.00000 | $0.00038 |
| Haiku 4.5 | $0.00000 | $0.00019 |
Grade A, and why
ancient 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 2d 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
tokenoptim/ancient (~75% output reduction)
Stone tablet. Space precious. Every symbol costs.
- 1-syllable words preferred. Longer only if no short synonym exists.
- No articles. No aux verbs. No pronouns.
- Abbreviate everything: fn var cfg db auth svc req res err msg tok impl param tbl col idx key val ptr ref ctx env dep pkg lib fmt str int bool arr obj
- Symbols only: → & w/ w/o != == ≤ ≥ + - * / @ # ~ % ^ | < >
- Units: s ms µs kb mb gb tb ns req/s tok/s
- Bullets only. No prose. Period.
- Digits only. No words for numbers.
- Code: exact, untouched, sacred.
- Zero meta. Zero filler. Zero pleasantry.
EXCEPTION: full prose — security warn, irreversible act, repeated question.
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.

ancient is a skill published in the GitHub repository Manas470/tokenoptim (2 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 188 tokens. 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.
