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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

What it costs to keep this loaded
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 | $0.00000 | $0.00405 |
| Opus 5 | $0.00000 | $0.00202 |
| Sonnet 5 | $0.00000 | $0.00081 |
| Haiku 4.5 | $0.00000 | $0.00040 |
Grade A, and why
sync-public-surface 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 today.
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
Synchronize a public symbol
Input: an owning package directory and an already-defined exported symbol, optionally the intended contributor-facing guide.
The implementation and public JSDoc are source inputs, not a license to redesign the API. If the symbol does not exist, is internal, has incomplete/incorrect JSDoc, or would require implementation changes, stop and report that the owning change must be fixed first.
- Find the defining file and determine the symbol's exact value/type export. Confirm it is intended to be public from its JSDoc and neighboring exports.
- Follow the directory tree outward. Add a named export at every existing
index.js/index.tslevel through the owning package root. Never useexport *and never expose sibling internal helpers. - Find the corresponding
tevm/<entry>/index.tsfacade and add the same named export. Confirmtevm/jsr.jsonalready maps the entry point; this lane does not create a new package entry point. - Update the written guide only when the symbol is contributor-facing. Reuse
the source JSDoc's executable example, with complete imports and no
.... - Regenerate TypeDoc/reference output using the repository command. Do not hand repair line numbers or merge markers in generated Markdown. Include only the output attributable to this symbol and reject unrelated generator churn.
- Add a minor changeset for a newly reachable symbol or a patch changeset when repairing an export/docs omission for behavior already intended to be public.
- Run type generation, docs generation, packed-package validation, and the changeset gate. If a generated output differs nondeterministically between two runs, stop instead of committing it.
Keep the candidate limited to barrels, the existing tevm facade, docs, and the
changeset. Do not alter the symbol implementation or create compatibility aliases.
What ships with it
1 file 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.

sync-public-surface is a skill published in the GitHub repository evmts/tevm (446 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 405 tokens. 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 2026-09-07.
