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 | $0.00045 | $0.00787 |
| Opus 5 | $0.00023 | $0.00394 |
| Sonnet 5 | $0.00009 | $0.00157 |
| Haiku 4.5 | $0.00005 | $0.00079 |
Grade A, and why
info-defrag 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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Info Defrag
Scan the codebase for stale information, inconsistencies, and broken references. This catches drift that happens when experiments get merged but docs don't get updated.
What to check
1. Experiment count
The number of experiments appears in multiple files. They drift.
# Actual count
wc -l research/log.jsonl
grep -c "^| exp" DISCOVERIES.md
# Where the number appears
grep -rn "33 experiment\|34 experiment\|35 experiment\|36 experiment" docs/ CLAUDE.md README.md
Fix any file that shows a different number than the log.
2. Best methods table
CLAUDE.md and DISCOVERIES.md both have a methods ranking table. They should match.
# Compare the two
grep -A10 "Current Best Methods" CLAUDE.md
grep -A10 "DMC baseline rankings" DISCOVERIES.md
3. People descriptions
Contributors change roles. Check docs/context.md People table against recent git log.
# Who contributed recently
git log --format="%an" --since="2 weeks ago" | sort -u
If someone submitted experiments, their bio should mention it.
4. Timeline coverage
The gantt chart in docs/context.md should cover recent work.
# Last date in the timeline
grep -o "2026-[0-9-]*" docs/context.md | sort | tail -1
# Last commit date
git log --format="%ai" -1 | cut -d' ' -f1
If the gap is more than a week, extend the timeline.
5. Index pages
Check that index files list all their children.
# Catchups
ls docs/catchups/*.md | wc -l
grep -c "\.md" docs/catchups/index.md
# Sessions
ls docs/sessions/*.md | grep -v transcript | wc -l
grep -c "\.md" docs/sessions/index.md
# Findings in nav
ls docs/findings/exp*.md | wc -l
grep -c "findings/" mkdocs.yml
6. Broken file references
Check that files mentioned in docs actually exist.
# Find markdown links and check targets
grep -roh '\[.*\](\.\./[^)]*\.md)' docs/ | grep -o '(.*\.md)' | tr -d '()' | sort -u | while read f; do
resolved="docs/$f"
[ ! -f "$resolved" ] && echo "BROKEN: $f"
done
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.

info-defrag is a skill published in the GitHub repository cybertronai/SutroYaro (16 stars, last pushed 3mo ago), licensed Unlicense. It adds 45 tokens to every session and 787 once invoked, about $0.0002 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 2026-08-30.
