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 | $0.00043 | $0.01503 |
| Opus 5 | $0.00022 | $0.00751 |
| Sonnet 5 | $0.00009 | $0.00301 |
| Haiku 4.5 | $0.00004 | $0.00150 |
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 5d 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.
This is a copy
94% identical to oracle — 5 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 112 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Oracle (CLI) — best use
Oracle bundles your prompt + selected files into one “one-shot” request so another model can answer with real repo context (API or browser automation). Treat outputs as advisory: verify against the codebase + tests.
Main use case (browser, GPT‑5.2 Pro)
Default workflow here: --engine browser with GPT‑5.2 Pro in ChatGPT. This is the “human in the loop” path: it can take ~10 minutes to ~1 hour; expect a stored session you can reattach to.
Recommended defaults:
- Engine: browser (
--engine browser) - Model: GPT‑5.2 Pro (either
--model gpt-5.2-proor a ChatGPT picker label like--model "5.2 Pro") - Attachments: directories/globs + excludes; avoid secrets.
Golden path (fast + reliable)
- Pick a tight file set (fewest files that still contain the truth).
- Preview what you’re about to send (
--dry-run+--files-reportwhen needed). - Run in browser mode for the usual GPT‑5.2 Pro ChatGPT workflow; use API only when you explicitly want it.
- If the run detaches/timeouts: reattach to the stored session (don’t re-run).
Commands (preferred)
-
Show help (once/session):
npx -y @steipete/oracle --help
-
Preview (no tokens):
npx -y @steipete/oracle --dry-run summary -p "<task>" --file "src/**" --file "!**/*.test.*"npx -y @steipete/oracle --dry-run full -p "<task>" --file "src/**"
-
Token/cost sanity:
npx -y @steipete/oracle --dry-run summary --files-report -p "<task>" --file "src/**"
-
Browser run (main path; long-running is normal):
npx -y @steipete/oracle --engine browser --model gpt-5.2-pro -p "<task>" --file "src/**"
-
Manual paste fallback (assemble bundle, copy to clipboard):
npx -y @steipete/oracle --render --copy -p "<task>" --file "src/**"- Note:
--copyis a hidden alias for--copy-markdown.
Attaching files (--file)
--file accepts files, directories, and globs. You can pass it multiple times; entries can be comma-separated.
- Include:
--file "src/**"(directory glob)--file src/index.ts(literal file)--file docs --file README.md(literal directory + file)
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.

oracle is a skill published in the GitHub repository davidtoby/agent-skills (10 stars, last pushed 1mo ago), licensed MIT. It adds 43 tokens to every session and 1,503 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 94% identical to oracle, differing in 5 lines, and is treated as a copy.
