📝 Walkthrough

Walkthrough

TinyInference replaces the former TinyBus template workspace with provider-neutral Rust APIs for model calls, streaming, tools, usage, caching, embeddings, retrieval, and OpenAI-compatible providers.

Changes

Workspace migration

Layer / File(s)	Summary
Workspace migration and retired template removal .github/..., Cargo.toml, AGENTS.md, README.md, crates/template*, docs/...	The workspace now targets TinyInference. The former template crates, TinyBus integration, release workflow, and related documentation are removed.
Provider-neutral core contracts crates/tinyinference/Cargo.toml, crates/tinyinference/src/{lib,error,failure,message,model,tool,usage}*	The crate adds structured message, model, stream, tool, error, failure, and usage APIs with public re-exports.

Runtime capabilities

Layer / File(s)	Summary
Response and prompt caching crates/tinyinference/src/cache/*	The cache module adds deterministic request keys, an LRU response cache, prompt-prefix layouts, cache policies, and layout events.
Embedding and retrieval subsystem crates/tinyinference/src/embeddings/*	The embeddings subsystem adds vector contracts, cosine search, retrieval, OpenAI-compatible, Cohere, Voyage, Ollama, cloud, and no-op models, plus retry and rate-limit helpers.
Provider configuration and mock execution crates/tinyinference/src/providers/{mod,types,mock,test}.rs	The provider layer adds provider specifications, provider inference, deterministic mock models, scripted responses, tool calls, and streaming behavior.
OpenAI-compatible provider flow crates/tinyinference/src/providers/openai/*	The OpenAI provider adds request and response conversion, authentication, provider presets, tool recovery, reasoning extraction, Responses API support, local-server degradation, and SSE reconstruction.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk:🟠 High · up to 3ce8c

This PR introduces provider and embedding APIs, but the current implementation can expose API keys, corrupt or partially index retrieval data, misassociate embeddings with documents, and drop tool-result content. These are high-impact security and correctness risks, so the PR is not merge-ready until they are fixed or explicitly accepted.

Poem

A rabbit reviews the model flow,
With streams that hop and caches glow.
Tools find names, embeddings race,
Messages keep their ordered place.
TinyInference blooms in code,
While carrots cheer the lighter load.

Inline comments:
In @.github/workflows/ci.yml:
- Line 15: Update the actions/checkout@v4 step to disable persisted credentials
by setting persist-credentials to false, ensuring subsequent Cargo build and
test steps cannot access the checkout token.
In `@crates/tinyinference/src/cache/mod.rs`:
- Line 248: Update the cache fingerprint logic around fnv1a_hex so it
incorporates each segment’s prompt_fingerprint when available, rather than
hashing only prefix_ids; ensure is_prefix_stable_against and CacheLayoutEvent
detect changed stable-prefix content even when ids match, and add a regression
test covering equal ids with different prefix fingerprints.
In `@crates/tinyinference/src/embeddings/cohere.rs`:
- Line 18: Replace the derived Debug implementation for CohereEmbeddingModel
with a custom implementation that omits or redacts api_key while preserving
useful debug output for non-sensitive fields.
In `@crates/tinyinference/src/embeddings/mod.rs`:
- Line 252: Validate that the vector count matches the document count in the
index flow before entering the loop that calls VectorStore::add. Reject
mismatched embedding batches instead of relying on the zip in the docs/vector
iteration, while preserving normal processing when counts match.
In `@crates/tinyinference/src/embeddings/noop.rs`:
- Line 27: The Retriever indexing flow must not pass embeddings from
NoopEmbeddingModel to InMemoryVectorStore::add, since its zero-length vectors
are invalid. Update Retriever::index or the semantic-search dispatch to
short-circuit when semantic search is disabled, while preserving a keyword-only
retrieval path for those configurations.
In `@crates/tinyinference/src/embeddings/ollama.rs`:
- Around line 272-273: Update the text filtering logic in the embedding
preparation flow to use trim() only for blank-input detection while preserving
the original text, including surrounding whitespace, in live and the value sent
to Ollama. Keep blank or whitespace-only inputs excluded and retain the existing
index association.
In `@crates/tinyinference/src/embeddings/openai.rs`:
- Line 241: Update OpenAiEmbeddingModel::embed around the data iteration to
build the output vectors according to each response item’s index rather than
received order. Validate and reject duplicate, missing, or out-of-range indices
before returning, while preserving positional alignment expected by
Retriever::index.
- Line 41: Replace the derived Debug implementations for OpenAiEmbeddingModel
and VoyageEmbeddingModel with manual redacted implementations that never include
api_key in formatted output. Preserve useful non-secret fields, and add
regression tests verifying Debug output omits the credential for both models.
Apply the same fix in `@crates/tinyinference/src/embeddings/ollama.rs` at line
277: The same credential exposure occurs in CohereEmbeddingModel.
In `@crates/tinyinference/src/message/types.rs`:
- Around line 24-25: Update the OpenAI tool-result translation in the provider
conversion flow to preserve ContentBlock::Json instead of relying on
Message::text(), which only retains ContentBlock::Text. Serialize JSON blocks as
canonical JSON text while constructing the tool message, keeping existing
text-block handling unchanged.
In `@crates/tinyinference/src/model/types.rs`:
- Around line 474-479: Update the terminal-item documentation for the stream
type around ModelStreamItem and StreamAccumulator::is_terminal to include
ProviderFailed alongside Completed and Failed as valid terminal variants, while
preserving the existing descriptions of the completion and failure behavior.
In `@crates/tinyinference/src/providers/openai/prompt_tools.rs`:
- Around line 117-121: Update parse_chat_response so handling cleaned tool-call
text replaces only visible ContentBlock::Text entries instead of overwriting
message.content entirely. Preserve any existing non-text blocks, especially
ContentBlock::Thinking produced for reasoning, while retaining the current
empty-text behavior.
In `@crates/tinyinference/src/providers/openai/README.md`:
- Line 1: Update the README title and the stale references around the documented
examples to use TinyInference’s public API: replace harness terminology,
TinyAgentsError, and harness::retry::is_retryable with their corresponding
tinyinference names and paths, while preserving the documented behavior and
examples.
In `@crates/tinyinference/src/providers/openai/sse.rs`:
- Around line 353-357: Update the SSE processing flow around process_line,
drain_lines, and sse_next so parsing stops once terminal_emitted is set by a
mid-stream error. Prevent remaining lines in the current buffer and all later
chunks from adding MessageDelta or ToolCallDelta entries to pending, while
preserving the terminal ProviderFailed item as the final stream item.
In `@crates/tinyinference/src/providers/openai/transport.rs`:
- Line 289: Update the rustdoc reference to SummarizationPolicy::from_profile
near the transport documentation so it resolves to an existing symbol in the
crate, or remove the link if no valid target exists. Do not leave a reference to
the nonexistent summarization module.
In `@README.md`:
- Line 27: Remove the hidden-line prefixes from the README code example,
including the leading # characters on the affected lines, so GitHub renders the
Rust snippet correctly. Keep the example content unchanged otherwise.

Reject incompatible JSON SSE payloads

When an SSE event is syntactically valid JSON but cannot deserialize as ChatCompletionChunk—for example {"choices":"corrupt"}—this if let silently ignores it. If a later [DONE] arrives, the stream emits Completed with partial or empty output instead of ProviderFailed. Fresh evidence after malformed-event handling was added: only JSON syntax errors are rejected; schema-incompatible JSON still falls through here.

[chatgpt-codex-connector]

Preserve Responses IDs for continuation

On every Responses-primary call, the provider's top-level response ID is discarded and the normalized assistant message always receives None. A caller therefore cannot obtain the ID needed by with_continuation_id without parsing ModelResponse::raw as provider-specific JSON. Fresh evidence after request-side continuation support was added: previous_response_id is now sent, but the corresponding response ID is still not deserialized or normalized.

[chatgpt-codex-connector]

Mark missing Responses arguments invalid

When a Responses function_call omits its required arguments field, this fabricates {} and constructs a valid ToolCall. For a no-argument or permissively schemed tool, validation then succeeds and a malformed provider call can be executed with invented arguments; preserve the missing/raw state as ToolCall::invalid or reject the response instead.

[chatgpt-codex-connector]

Preserve structured system instructions in Responses

On the Responses-primary path, a system message containing ContentBlock::Json is reduced to an empty instruction because message_text retains only text blocks; system images and provider extensions are silently discarded as well instead of rejected. Fresh evidence after the Chat Completions system conversion was fixed: this separate Responses branch bypasses input_parts, so the same normalized content is still lost here.

AGENTS.md reference: AGENTS.md:L38-L41

Useful? React with 👍 / 👎.

[chatgpt-codex-connector]

Serialize structured assistant content

When replaying an assistant turn containing ContentBlock::Json, message.text() drops the JSON block, so Chat Completions receives empty or partial assistant content. This loses prior structured output on a follow-up request even though system, user, and tool conversion already serialize normalized JSON blocks; assistant content should use the same block-aware translation.

[chatgpt-codex-connector]

Map Responses usage detail fields

The Responses usage wire type retains only input and output totals, so reported cache-read and reasoning-token details are discarded during deserialization. Consequently both unary Responses calls and the stream wrapper return zero cache_read_tokens and reasoning_tokens, unlike the Chat Completions path, which maps these normalized usage fields; deserialize and map the Responses detail objects as well.

Restore the per-file 90% line coverage gate in CI

The earlier finding about the removed coverage gate has not been fixed: the diff deletes the step that runs .github/scripts/check-file-coverage.sh and the upload of the coverage report. Without this gate, regressions in line coverage can go undetected. The repository's rules require unit tests and this gate enforces that, so it should be restored.

Implement the signature() method required by the EmbeddingModel trait

The EmbeddingModel trait requires a signature() method (as shown in the test identity_and_defaults_match_host_contract which calls model.signature()). The trait impl provides name(), model_id(), dimensions(), embed(), and embed_query(), but is missing signature(). This will fail to compile.

Fix doc example that calls nonexistent response.text()

The doc example calls response.text() on a ModelResponse, but ModelResponse does not expose a .text() method — it exposes a .messages() method that returns the full conversation, or specific content block accessors. This example would fail to compile, misleading anyone who copies it. Replace the assertion with the correct access pattern used elsewhere in the crate's production code and tests.

Re-export ModelStreamItem which may be private in its module

The line pub use model::{ChatModel, ModelRequest, ModelResponse, ModelStream, ModelStreamItem}; attempts to re-export ModelStreamItem. However, if ModelStreamItem is not declared pub inside crate::model (i.e., it is module-private or just pub(self)), the re-export will fail to compile with a privacy error. The surrounding diff shows the model module is pub mod model;, but the visibility of ModelStreamItem itself is not shown in this diff. This is a common gotcha when setting up public API surface. The fix is to ensure ModelStreamItem is pub in the model module, or to remove it from the re-export list if it is not intended for public consumption.

Read MSRV from Cargo.toml instead of hardcoding 1.88.0

The earlier finding about reading MSRV from Cargo.toml has not been fixed. The diff replaces a dynamic extraction of rust-version from cargo metadata with a hardcoded 1.88.0. When the workspace rust-version is updated, this CI job will silently test against the wrong version until someone remembers to update this literal. The original approach was correct and should be restored.

Replace unpinned cargo-deny installation with pinned action

cargo install cargo-deny --locked fetches the latest published version, which is not pinned. If a new version changes behaviour or is yanked, the job breaks unreproducibly. The earlier finding about this was addressed by removing EmbarkStudios/cargo-deny-action@v2 and switching to cargo install, but that does not pin the version. Consider using a pinned action (e.g., EmbarkStudios/cargo-deny-action@v2 with a commit SHA) or pinning a specific version like cargo install cargo-deny@0.16.0.

Use standard FNV-1a constants instead of non-standard values

The values in this code appear to be derived from an informational memo about a similar hash, not the standard FNV-1a. Because the signature explicitly states 'Computes a deterministic FNV-1a 64-bit hash', callers (especially test authors reading the fingerprint) would expect the standard algorithm. Using non-standard constants means the output will differ from any other FNV-1a implementation, breaking the stated determinism and making cross-referencing with tooling impossible. Use the standard FNV-1a constants as published. This is a design-level correctness issue, not a style preference.
