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 | $0.00225 | $0.00225 |
| Opus 5.5 | $0.00090 | $0.00090 |
| Sonnet 5.5 | $0.00045 | $0.00045 |
| Haiku 4.5 | $0.00022 | $0.00022 |
Grade A, and why
possible 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 2mo 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
Possible
Possible is an open-source directory of inspectable results and exact reusable prompts.
Before editing:
jj status
npm run test -w @possible/catalog
Outcome publishers own canonical outcome.json, outcome.md, and prompt.md files in their public repository or domain. This repository owns the directory clients and public contract; it does not own Product or Skill catalogs. Do not add canonical Outcomes here.
Keep the separation exact: human title and explanation in outcome.md; full prompt in prompt.md; models, Products, Skills, requirements, provenance, and file metadata in outcome.json. Do not reintroduce a pack compiler, authored expectations, workstreams, lifecycle, or execution ceremony.
Publishers own their canonical public GitHub repository or domain source. Possible stores immutable discovery snapshots but does not host publisher accounts. The optional $possible Skill may prepare a new prompt at run time; it must not rewrite a published prompt.
Run npm run check before handoff. Use Jujutsu. Do not push or deploy unless explicitly requested.
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.
