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 | $0.02000 | $0.02000 |
| Opus 5.5 | $0.00800 | $0.00800 |
| Sonnet 5.5 | $0.00400 | $0.00400 |
| Haiku 4.5 | $0.00200 | $0.00200 |
Grade A, and why
aios CLAUDE.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 1mo 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 — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE — AI OS entry point
This vault is an AI Operating System (plain markdown, no plugins, portable across AI tools). Everything the AI needs lives in AIOS/.
New vault? Run
/aios-bootstrap(or pasteBOOTSTRAP.mdinto your agent) once. It interviews you, fills in the<placeholders>below, and rewrites this file.
Start here, every session
- Read
AIOS/Systems/layers.tsv— the scopes this vault partitions knowledge into. A single-scope vault is normal; if there's one row, skip the ceremony. - Read the me file for the scope this task belongs to:
<scope>/me.md. - Read
AIOS/Maps/Vault Map.md— how to navigate and where new notes go. - Read
AIOS/Maps/Skill Map.md— every skill/system and its trigger. Skills live inAIOS/Skills/, systems inAIOS/Systems/.
Scopes
A scope is a bucket of context — a job, a side project, a client, a life area. Its job is routing: it keeps one project's accumulated memory out of an unrelated one, and tells the AI which me.md file to read.
- The scope is the filesystem: each scope is one top-level directory named by its slug —
<scope>/me.md,<scope>/notes/,<scope>/content/,<scope>/projects/,<scope>/sources/. A path's first segment names its scope; that prefix is what the write guard, ingest, and leak audits key on. - Every content note also carries a
layer:frontmatter field naming its scope. - Ingest, query, and lint each work one scope at a time, so a synthesis note never blends two unrelated contexts. This is about keeping knowledge coherent, not about secrecy.
Strict separation (optional — off by default)
Most vaults do not need this. Skip the whole section unless it applies to you.
Some people keep scopes that must never appear in the same file — a pen name that can't be linked to a legal name, employer-proprietary code that can't reach a public portfolio or a job application, one client's internals that can't surface in another's repo. If that's you, enable the wall by filling in the tokens column of AIOS/Systems/layers.tsv.
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.

aios CLAUDE.md is an instructions file published in the GitHub repository sublimecoder/aios (2 stars, last pushed 1mo ago), licensed MIT. It adds 2,000 tokens to every session, about $0.0080 per session on Opus 5.5. 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.
