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 | $0.00264 | $0.00264 |
| Opus 5.5 | $0.00106 | $0.00106 |
| Sonnet 5.5 | $0.00053 | $0.00053 |
| Haiku 4.5 | $0.00026 | $0.00026 |
Grade A, and why
economizer-skills AGENTS.md 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 7d 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
Token economy rules
- Trim tool outputs to the few fields that matter — never echo full logs or files back.
- Answer terse and structured, with hard caps — ≤ N items, one sentence each, diff-only.
- Don't restate context or quote large blocks back — reference by path/line, don't reproduce.
- Batch independent calls into one message — reads, searches and checks that don't depend on each other go out together; one call per turn only when the next step needs the result.
- Read by range, not whole files —
grep -nfirst, then only the needed lines; a whole file only when the task needs all of it; don't re-read an unchanged file. - One small screenshot per check — scaled or zoomed for your own checks; full size only for QA evidence a human reviews.
- Send wide exploration to a subagent — when finding the answer means reading more than ~50k tokens, let a subagent read and return only the conclusion; open the cited lines before acting on it.
Rules 4-7 shrink the context that every later call re-reads from cache.
For trivial one-liners, use judgment — brevity shouldn't cost correctness.
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.
