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 | $0.00031 | $0.01279 |
| Opus 5 | $0.00015 | $0.00639 |
| Sonnet 5 | $0.00006 | $0.00256 |
| Haiku 4.5 | $0.00003 | $0.00128 |
Grade A, and why
check-rumination 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 11d 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 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.

check-rumination is a skill published in the GitHub repository tlennon-ie/neurodock (12 stars, last pushed today), licensed AGPL-3.0. It adds 31 tokens to every session and 1,279 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.

save
Substrate-mediated pre-compaction — turn recent dialogue into engrams and standing rules BEFORE the context window collapses, so memory survives the cut. Run BEFORE Claude Code's native /compact (which only summarizes-and-drops; engrams persist across sessions, summaries don't). Previously named compact (collided with…
forget
Soft-delete substrate engrams matching a pattern by recording a tombstone. Originals stay for audit; retrieval excludes them.
troth-memory
Use this skill when starting any code task in a project that has a troth substrate. It mandates a query-first workflow — load prior verified work and unresolved page-handles before editing, instead of re-deriving from scratch.
init
Scan the current working directory and write project anchors so future turns load that context automatically.
think
Emit a structured reasoning trace and persist it to substrate as a causal record for future /recall to walk.
