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 | $0.00080 | $0.01970 |
| Opus 5.5 | $0.00032 | $0.00788 |
| Sonnet 5.5 | $0.00016 | $0.00394 |
| Haiku 4.5 | $0.00008 | $0.00197 |
Grade A, and why
extend-schema 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 — 170 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Extend the dismech LinkML Schema
When to use
- Adding a class, slot, or enum to
src/dismech/schema/dismech.yaml. - Narrowing, deprecating, or removing an existing one.
- Deciding whether a curation need warrants a schema change at all.
- Migrating
kb/content after a schema change lands.
Do not use for: filling an existing slot (use the curation skills),
ontology meaning / reachable_from bindings inside dynamic enums (use
dismech-terms), or kb/groupings/ membership logic (use curate-grouping).
The schema files
| File | Class it governs |
|---|---|
src/dismech/schema/dismech.yaml |
Disease (disorders, modules), Grouping, ModuleCollection — 322 KB, the main one |
src/dismech/schema/curation_stub.yaml |
CurationStub (stubs/) |
src/dismech/schema/history.yaml |
history/ records |
src/dismech/schema/hypothesis_assessment.yaml, hypothesis_reconciliation.yaml |
kb/hypotheses/ |
src/dismech/schema/research_synthesis.yaml |
deep-research synthesis |
src/dismech/schema/classifications/ |
the classifications block |
src/dismech/schema/dismech.history.yaml |
not a schema — an auto-appended edit log beside dismech.yaml. Never hand-edit it; validate-all skips *.history.yaml |
This guide mostly pertains to the core schema ie dismech.yaml
Do Background Research
It is likely your proposal has been discussed before. Be sure to check issues.
Major Schema Changes should be approved
If you are reviewing a schema change and it is not trivial, block merging until approved by @cmungall or @mellybelly.
Have a data population strategy
It is easy to have "nice to have" new slots. But think hard about the population strategy.
Will this be deterministically populated? If so, include code.
If non-deterministic, you MUST include string guidelines on how to populate. Especially if subjective in nature. We want to avoid situations where agent and reviewer go back and forth arguing on populating the slot because we underspecified how it was to be populated.
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.

extend-schema is a skill published in the GitHub repository monarch-initiative/dismech (69 stars, last pushed today), licensed BSD-3-Clause. It adds 80 tokens to every session and 1,970 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 2026-09-18.
