The host supplies repository snapshots or +indexes; Embed supplies argument validation and the model-facing envelope. +This module opens no files, runs no commands, makes no network requests, and +has no workspace or write API. + +## Host contract + +Implement the async `RepositoryHost` trait using `async_trait`: + +- `query(RepositoryQuery) -> anyhow::Result` handles a validated + `List`, `Read`, `Search`, `Lookup`, or `GitShow` request. +- `redact(String) -> anyhow::Result` removes secrets before any data + enters the tool result or conversation. This method is required; an identity + implementation is appropriate only for a source already known to be safe. + +The host is trusted code. It must enforce repository scope, permissions, +symlink containment, and snapshot identity, bound its own CPU/memory/IO costs, +and never execute contributor code. A path's lexical validation cannot enforce +filesystem containment. Prefer an immutable tree/index to filesystem access. +Treat search terms as literal data, and never interpolate them into commands. +The facade also re-exports `ToolResult` for custom host tools; consumers need +no direct dependency on `openhuman-core`. + +## Model-facing tools + +| Tool | Arguments | Semantics | +| --- | --- | --- | +| `repo_list` | `path`, `limit` | Tree or directory entries; `.` means the repository root. | +| `repo_read` | `path`, `start_line`, `end_line` | Inclusive, one-based file range. | +| `repo_search` | `path`, `query`, `limit` | Literal text search beneath a path; `.` means root. | +| `repo_lookup` | `symbol`, `limit` | Host-defined symbol, callers, references, or graph lookup. | +| `repo_git_show` | `commit`, `path`, `start_line`, `end_line` | Inclusive file range at an immutable commit ID. | + +All arguments are required; unknown fields are refused. Limits are 1–200 +results, 1–1,000 lines per range, 4,096 UTF-8 bytes per path, and 1,024 UTF-8 +bytes per nonempty search term or symbol. Paths must be normalized relative +paths: absolute paths, backslashes, colons, tildes, controls, empty components, +`.`/`..` components, and `.git` components are refused. Root `.` is permitted +only for listing and search. Commits must be full 40- or 64-character ASCII +hexadecimal IDs; symbolic refs, abbreviations and revision expressions are +refused. Validation happens before calling the host. + +Every successful query passes through redaction, then becomes compact JSON +inside a Markdown fence labeled `UNTRUSTED_REPOSITORY_DATA`. JSON escapes +embedded newlines, preventing repository text from ending the fence. The +model-facing text is bounded to 65,536 bytes, including its envelope; long +results are truncated at a UTF-8 boundary and carry `truncated: true`. +Host and redactor failures return generic errors, never their diagnostic text. +No raw host output is logged or included as metadata. + +## Attach to a reviewer + +```rust,no_run +use std::sync::Arc; +use openhuman_embed::{Access, AgentDefinitionSpec, AgentSpec, HostTurnTools, ToolScopeSpec}; +use openhuman_embed::repository::{RepositoryHost, repository_tools}; + +fn reviewer(host: Arc) -> AgentSpec { + AgentSpec::new("reviewer") + .access(Access::readonly()) + .definition(AgentDefinitionSpec::new() + .bare_prompt("Review code.

Completed spend plus every live +reservation must fit the turn and ancestor ceilings. Usage reconciliation is +atomic too. Once refused, no provider request is sent; the facade returns +`CoreError::BudgetExceeded` with completed spend, outstanding reservations, +requested reservation and refusing limits. + +Choose conservative per-call bounds for **all allowed routes**, including +fallback prices, reasoning and cached-input billing. This is pre-call admission, +not a provider-side monetary cap: an incorrect bound or a provider violating its +output cap can exceed the reservation. Actual excess is recorded and refuses +further calls. Missing cost, failed requests and cancellation retain the cost +reservation; unknown token usage retains the token reservation. This prevents +lost responses from quietly restoring spend that may already have been billed. + +Budgeted calls currently accept text input. Serialized message and tool-schema +bytes bound input tokens conservatively; the host's input bound must also leave +room for provider framing. Non-text inputs and pass-through output cap overrides +are refused before dispatch. Normal calls without a budget retain their existing +modality support. + +## Ordered bounded fanout + +`Runtime::fanout` and `fanout::fanout` accept `Vec`, a `NonZeroUsize` +concurrency bound and a shared `ModelBudget`. The free function suits stateless +completers without a runtime. `LeafCall` carries a completion or an owned turn; +`Branch::limits` adds a branch ceiling to the shared ledger. + +Every result occupies its input slot regardless of finish order. A root error +skips only its own children; errors in children are individually returned and +leave later children running. At most the declared number of branches execute +at once. A branch runs its root then its children sequentially. Dropping fanout +drops the in-flight futures; it leaves no spawned background calls. + +`Branch::children` accepts only `LeafCall`, which has no children method. Model +subagent depth is also narrowed at turn admission: root calls permit at most one +level and declared leaf calls permit none. The explicit host carrier inherits +the ceiling; TinyAgents and the OpenHuman spawn boundary check it before calls. +An unset agent session gets a fresh session ID. Hosts should supply distinct +session identities when setting them explicitly. + +Validation lives in `crates/openhuman-embed/tests/budget_fanout.rs`, +`structured_turns.rs`, the explicit run-carrier tests, and TinyInference's +`model/budget_tests.rs`. All provider fixtures run locally with wiremock or +scripted models. + +Hosts with borrowed tree readers or custom mock model futures can use +`fanout_futures(Vec>, concurrency)` instead. Its boxed +futures may borrow local inputs and retain their own error type. This scheduler +is also used by the typed primitive. Configure each model future's budget +explicitly; an opaque future may be entirely offline and is not assumed to +perform inference. diff --git a/vendor/tinyagents b/vendor/tinyagents index 5db9caf3b22..47111f9896e 160000 --- a/vendor/tinyagents +++ b/vendor/tinyagents @@ -1 +1 @@ -Subproject commit 5db9caf3b2224d8c49cdb29fe57196f9c3d34ca2 +Subproject commit 47111f9896e7ce68c1bd74aa9ffea417f3f61d9a From 13e503a4bbdb7589cd352c34be881292493f0afc Mon Sep 17 00:00:00 2001 From: Steven Enamakel Date: Sat, 10 Oct 2026 18:30:32 +0300 Subject: [PATCH 09/32] chore(embed): pin schema-aware provider budget admission Co-authored-by: Medulla --- vendor/tinyagents | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/vendor/tinyagents b/vendor/tinyagents index 47111f9896e..43586d85bad 160000 --- a/vendor/tinyagents +++ b/vendor/tinyagents @@ -1 +1 @@ -Subproject commit 47111f9896e7ce68c1bd74aa9ffea417f3f61d9a +Subproject commit 43586d85bad5fada66e9372463f55488f5de27f6 From 0910765e948616196d8964ae7df294ef0664c914 Mon Sep 17 00:00:00 2001 From: Steven Enamakel Date: Sat, 10 Oct 2026 18:47:48 +0300 Subject: [PATCH 10/32] feat(embed): bound whole turns with cleanup-aware deadlines Co-authored-by: Medulla --- crates/openhuman-embed/src/complete.rs | 9 ++++---- crates/openhuman-embed/src/turn.rs | 23 ++++++++++++++++--- .../tests/turn_cancellation.rs | 13 ++++++++++- 3 files changed, 36 insertions(+), 9 deletions(-) diff --git a/crates/openhuman-embed/src/complete.rs b/crates/openhuman-embed/src/complete.rs index 094fc1dd7f9..9f5140d0a07 100644 --- a/crates/openhuman-embed/src/complete.rs +++ b/crates/openhuman-embed/src/complete.rs @@ -282,11 +282,10 @@ pub struct CompletionUsage { pub struct CompletionResponse { /// The visible reply text (reasoning content excluded). pub text: String, - /// `text` parsed as JSON, when a JSON [`ResponseFormat`] was requested and - /// the reply parses.
