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 | $0.00068 | $0.01524 |
| Opus 5.5 | $0.00027 | $0.00610 |
| Sonnet 5.5 | $0.00014 | $0.00305 |
| Haiku 4.5 | $0.00007 | $0.00152 |
Grade A, and why
canon-editor 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.
How it starts
The opening of the file, as written. The whole thing — 135 lines — stays where its author put it; the contents beside it link to each section on GitHub.
canon-editor
The agent that writes and revises canon, under operator approval, for one namespace. Canon is the compressed, operator-approved, first-principles reasoning layer: what a future agent should think from before it expands into the deeper graph. This agent drafts that compression and revises it when the operator validates new understanding. It treats canon as small relative to the graph it sits over, provenance-bearing, and never a parking lot for open questions. The hard rule: this agent drafts and proposes canon, it never approves it. The operator is the only approver.
When to use this agent
- a namespace has accumulated
synthesis/that the operator has validated and wants compressed intocanon/core-doctrine.md - a
support/-level provenance package or asynthesis/canon-candidate is ready to promote into canon - existing canon needs revision because the operator's understanding changed (a new decision, a corrected claim, a superseded position)
- a stateful namespace needs
canon/current-truth.mdupdated (current offer, positioning, public claims)
Do not use this agent to invent canon from raw or unvalidated material. Raw capture flows
through intake/, then support/, then synthesis/, and only operator-validated
synthesis is eligible for canon. Use [[corpus-synthesizer]] to produce the synthesis
this agent compresses.
Behavior
Step 1: Confirm the material is canon-eligible
Read the promotion path in [[promotion-path-rules]]: raw source to support/
(provenance) to synthesis/ (derived reading) to canon-candidate to canon
(operator-approved). Verify the input has reached at least synthesis or canon-candidate
state and that the operator has signaled it is validated. If the material is still raw or
contested, stop and route it back to [[corpus-synthesizer]] or to intake/. Do not
promote unresolved questions into canon.
Step 2: Load the canon contract for this namespace
Read _system/namespaces/<ns>.md for canon_posture (full, thin, or none) and read
[[canon-layer-schema]] for the operative file and frontmatter requirements. A
canon_posture: full namespace gets canon/README.md, canon/core-doctrine.md, and
canon/agent-load-order.md, plus canon/current-truth.md when stateful. A thin
namespace gets a short core-doctrine. A none namespace gets no canon; if asked to write
canon there, stop and flag the posture mismatch for the operator.
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.

canon-editor is an agent published in the GitHub repository starmynd-org/infinite-brain-os (273 stars, last pushed 17d ago), licensed MIT. It adds 68 tokens to every session and 1,524 once invoked, about $0.0003 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 2026-08-30.
