What it does
Vero Source Verus is an agent skill from sunblaze-ucb/vero. Load BEFORE translating Verus source (Rust with verus! macro) to Lean 4. Provides Verus-specific classification rules (spec/proof/exec fn modes), type mappings (Seq/Map/Set vs List/AssocList), and patterns for mapping Verus constructs into the ratified bundle paradigm (Impl/ + Spec/ + Bundle + Harness). Pair with vero-discover, vero-plan, vero-translate, and vero-verus-pitfalls.
Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Writing & Content, covering Translation. It works with Rust. The licence is Apache-2.0.
When your agent uses it
- Tasks that involve Translation
Example prompts
- “/vero-source-verus”
Requirements
- Pre-approved tools (allowed-tools): Read, Write, Edit, Bash, Grep, Glob
What it can do on your machine
Read from SKILL.md and the folder at commit 0a7325d. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadWriteEditBashGrepGlob
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are rust, json and lean).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Vero Source Verus loads about 1.8k tokens when it runs. Until then it costs about 100 tokens; SKILL.md has 565 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: Read, Write, Edit, Bash, Grep, Glob
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

VCG Source: Verus → Lean 4
Verus-specific classification and translation patterns for the
ratified curation paradigm. The shape of the emitted Lean is
pinned by reference/BankLedger/ + .claude/skills/vero-translate/SKILL.md —
this skill teaches the language mapping.
Worked upstream exemplar: reference/BankLedger-source-verus/
translates 1:1 into reference/BankLedger/. Cite it when the mapping
is non-obvious.
When to use
- Classifying items in a Verus source (with
vero-discover). - Writing the translation plan (with
vero-plan). - Emitting Lean from Verus (with
vero-translate).
Output-shape recap (non-negotiable)
Per source module, translate emits:
<Project>/Impl/<Module>.lean— types +abbrev <Fn>Sigper API +def Bank.<fn> : Bank.<Fn>Sig := <translated reference impl>incode/code_auxmarkers.!curation @review v1annotations.<Project>/Spec/<Module>.lean—def spec_<…> (impl : RepoImpl) : Prop := …only. Frozen, no markers.- Bundle.lean, Harness.lean, Test.lean — shared, once per benchmark.
See .claude/skills/vero-translate/SKILL.md for file templates.
Verus fn modes → Lean classification
Verus declares every fn as exec, spec, or proof.
| Verus | Lean artifact | Markers? |
|---|---|---|
exec fn (an API) | def Bank.<fn> : Bank.<FnSig> := <translated reference impl> in Impl | Yes — code / code_aux |
exec fn (helper, not an API) | Full body in Impl | No |
spec fn (vocabulary) | def <name> : <type> := … in Impl or Spec helpers; full body | No |
proof fn / lemma (property worth tracking) | spec_<name> entry → def spec_<name> in Spec | No (Spec frozen) |
proof fn (pure proof helper) | Drop from plan — becomes proof_aux downstream | — |
#[verifier::external_body] | opaque in Impl; axiomatize | No |
axiom macro | axiom <name> : <type> near the related opaque | No |
#[test] | #guard in Test.lean | No |
Classify by role. A spec fn describing an invariant →
vocabulary, no markers. A proof fn capturing a postcondition →
spec_* entry.
Type mapping
| Verus | Lean 4 |
|---|---|
u64 / u32 / u8 | Nat (usually) |
i64 / i32 | Int |
bool | Bool |
String | String |
Vec<T> | List T |
Seq<T> (spec-only) | List T |
Map<K, V> (spec-only) | List (K × V) with uniqueness spec |
Set<T> (spec-only) | List T with uniqueness spec |
Option<T> | Option T |
Result<T, E> | Except E T |
(T, U) | T × U |
struct Foo { x: u64 } | structure Foo where x : Nat |
enum Foo { A, B(u64) } | inductive Foo where | A | B (_ : Nat) |
u64 → Nat policy. Verus forces overflow bounds via
requires/ensures; Lean's Nat has no overflow. Prefer Nat and
elide overflow conditions — #guard tests still pin observable
behavior. Note the divergence in the plan if the curator wants
explicit overflow specs.

Vec<T> vs Seq<T> and the @ view
In Verus, v@ lifts Vec<T> to Seq<T> for spec reasoning:
fn push(v: &mut Vec<T>, x: T)
ensures v@ == old(v)@.push(x)In Lean, both become List T. The @ view has no direct analogue —
drop it and operate on the List directly.
plan.json:
{
"name": "spec_push_appends",
"nl_description": "push extends the list with the new element at the end.",
"lean_form": "∀ (v : List T) (x : T), impl.bankLedger.push v x = v ++ [x]",
"apis_referenced": ["push"],
"curator_intended_truth": "prove"
}API translation pattern
Verus:
pub fn create_account(id: AccountId, ledger: Ledger) -> (r: Ledger)
requires /* … */
ensures /* post */
{ … }plan.json:
{
"upstream_name": "create_account",
"lean_name": "createAccount",
"sig_abbrev": "CreateAccountSig",
"lean_type": "AccountId → Ledger → Ledger",
"opaque": false,
"nl_description": "Add a new account with the given id to the ledger."
}Emitted Impl:
namespace Bank
abbrev CreateAccountSig := AccountId → Ledger → Ledger
end Bank
-- !benchmark @start code_aux def=createAccount
-- !benchmark @end code_aux def=createAccount
-- !curation @review v1 [ ] createAccount — Impl/Account, code, reference impl
def Bank.createAccount : Bank.CreateAccountSig :=
-- !benchmark @start code def=createAccount
-- translated Verus exec body, not `sorry`
...
-- !benchmark @end code def=createAccountPartial functions
- Type-enforced: use dependent argument or
Option. - Caller-error explicit:
Option <return>orExcept Err <return>. - Pick consistently within a benchmark.
Spec translation pattern
proof fn stating a property
proof fn deposit_preserves_sum(id: AccountId, amt: u64, l: Ledger)
ensures sum(deposit(id, amt, l)) == sum(l) + amt
{ … }plan.json:
{
"name": "spec_deposit_preserves_sum",
"nl_description": "Depositing `amt` adds exactly `amt` to the total.",
"lean_form": "∀ (id : AccountId) (amt : Balance) (l : Ledger), impl.bankLedger.totalAssets (impl.bankLedger.deposit id amt l) = impl.bankLedger.totalAssets l + amt",
"apis_referenced": ["deposit", "totalAssets"],
"curator_intended_truth": "prove"
}Emitted Spec:
/-- Depositing `amt` adds exactly `amt` to the total. -/
def spec_deposit_preserves_sum (impl : RepoImpl) : Prop :=
∀ (id : AccountId) (amt : Balance) (l : Ledger),
impl.bankLedger.totalAssets (impl.bankLedger.deposit id amt l) =
impl.bankLedger.totalAssets l + amtlemma_* proof helper
Many auxiliary lemmas per API under Verus — in the new paradigm they
don't become separate benchmark artifacts. Drop from plan.json. The
LLM may introduce similar helpers in proof_aux slots downstream.
external_body and opaque functions
#[verifier::external_body]
pub fn now() -> u64 { … }Translate to:
opaque Bank.now : Unit → Nat
-- If Verus guarantees a postcondition:
axiom Bank.now_positive : ∀ u, Bank.now u > 0Mark opaque: true in plan.json. No code markers for opaque
functions.
Common pitfalls (see vero-verus-pitfalls)
&mut+old(x)@has no Lean analogue; specs become value-passingf x = ….- Verus
assumeclauses are red flags; surface as!curation @review. decreasesclauses are proof hints; use them only when Lean needs termination help for the translated Impl body.- Trait-method calls may dispatch dynamically; Lean pins to concrete
