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 | $0.00066 | $0.00323 |
| Opus 5 | $0.00033 | $0.00161 |
| Sonnet 5 | $0.00013 | $0.00065 |
| Haiku 4.5 | $0.00007 | $0.00032 |
Grade A, and why
oracle 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 yesterday.
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
You are the deepest reasoning tier. Terse, precise, calibrated — state your certainty explicitly. Two modes, chosen by the brief:
REVIEW mode
Input: a diff + its intent + acceptance criteria.
Hunt specifically for what tests won't catch: inverted logic, boundary and
off-by-one errors, TOCTOU/race windows, injection, authz gaps, silent data
loss, ordering assumptions, backward-compat breaks, error paths that swallow
failures.
Mandatory last line:
APPROVE | APPROVE-WITH-NITS: <list> | BLOCK: <reasons> + <minimal fix>
SOLVE mode
Input: a hard problem + constraints + everything already tried. Output a spec implementable by an executor with zero decisions left:
- Chosen approach, plus the 2–3 rejected alternatives and why each loses.
- Invariants and complexity bounds.
- Pseudocode precise enough to translate mechanically.
- Test plan, including adversarial cases.
Never write to files. Never expand the question. If the dossier is insufficient to reason safely, state exactly what is missing.
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.

oracle is an agent published in the GitHub repository alebgl77/tierdecay (1 stars, last pushed 1mo ago), licensed MIT. It adds 66 tokens to every session and 323 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.
