Summary

The docs were built around a positioning the project no longer has: a "recursive language model (RLM) harness", CodeAct, a .ragsh REPL/interpreter language, and "self-authoring" models. This replaces that framing across the README, docs/, the root project files, and the wiki.

New positioning, used consistently everywhere:

TinyAgents is a small, provider-neutral agent harness for Rust, plus a durable typed state-graph runtime. It takes its shape from LangChain (models, tools, middleware, structured output, streaming, usage/cost) and LangGraph (START/END, nodes, conditional edges, channels/reducers, checkpoints, interrupts, subgraphs, time travel) — rebuilt as ordinary, typed Rust.

Sub-agents and subgraphs still exist in the code and stay documented, but as ordinary composition ("an agent can be exposed as a tool to another agent"; "a node can embed a compiled graph") rather than as a recursion thesis. The .rag blueprint language is unchanged and still documented.

Changes

  • README.md — rewritten, 328 → 233 lines. Real crate layout, real feature flags, quickstart, providers, examples index.
  • docs/spec/README.md — dropped the "Host-side surfaces" interpreter essay and the RLM/CodeAct positioning bullet. Also dropped the rust-langgraph and "OpenHuman PR #4261" precedent bullets, which read as internal scratch notes rather than specification. The LangChain/LangGraph lineage is kept.
  • docs/modules/expressive-language/ — CodeAct branding removed; repl_agent kept and described factually.
  • docs/modules/harness/local-models.md — fixed two pre-existing broken links to tests/live_local_*.rs, which moved to crates/tinyagents-integration-tests/tests/.
  • CONTRIBUTING.md — removed the .ragsh Rhai repl feature section (no such feature or dependency exists); replaced with the real package-local feature list. Corrected build/test commands to --workspace and the example command to -p tinyagents-integration-tests.
  • SECURITY.md.ragsh reference removed; dropped a false "pre-1.0" claim (the workspace is at 2.1.2).
  • ROADMAP.md — removed the .ragsh REPL language and Rhai session-runtime items; corrected the stale v1.5.0 version line.
  • AGENTS.md — removed the "CodeAct/REPL loop is a host concern" line.
  • wiki — submodule pointer bumped to 5b8f592.

Wiki

The wiki submodule commit is on branch docs-minimal-harness in tinyagents.wiki.git. GitHub wikis have no pull request interface, so that branch is pushed for review but cannot be merged through a PR — it needs a separate push to the wiki's master to publish.

It deletes Recursion-and-RLM.md and REPL-Language-RAGSH.md and rewrites all 13 remaining pages. Beyond the positioning, the wiki was structurally stale: it still described a single tinyagents crate with src/harness/, src/graph/, src/repl/, and linked to crates.io and docs.rs.

Notable findings

  • Every workspace crate is publish = false. Nothing is on crates.io, so the old cargo add install instructions and all crates.io/docs.rs links were wrong. The README now documents git dependencies.
  • repl_agent is still a real node kind in tinyagents-language and tinyagents-registry. It stays documented, minimally, as a hook for a host-supplied script node; only the CodeAct framing around it was removed.
  • docs/spec/README.md keeps one .ragsh mention under "Open Questions", correctly framed as a settled historical decision explaining the .rag extension. Left in place as accurate.

Verification

  • Both README code samples were extracted into a temporary example and cargo checked against the real API; they compile. The scratch file was removed.
  • A relative-link check over README.md, the root project files, and all of docs/ reports zero broken links.
  • grep -rniE "\bRLM\b|ragsh|codeact|recursive language|self-author" across the superproject and wiki is clean apart from the historical note above.
  • Crate names, module paths, and feature flags were each checked against the relevant Cargo.toml and src/lib.rs.

Docs only — no source changes.

Summary by CodeRabbit

  • Documentation

📝 Walkthrough

Walkthrough

The pull request updates TinyAgents documentation for its workspace structure, package features, architecture, .rag language, project scope, roadmap, security policy, and test links. It also advances the TinyInference and wiki subproject references.

Changes

TinyAgents documentation alignment

Layer / File(s) Summary
Workspace onboarding and usage
CONTRIBUTING.md, README.md
Workspace commands, package-local features, crate dependencies, examples, providers, and usage sections were updated.
Architecture and execution scope
docs/spec/README.md, docs/modules/expressive-language/*, AGENTS.md
The documentation now defines harness, graph, registry, and .rag boundaries without CodeAct-style recursive orchestration.
Project status and documentation links
ROADMAP.md, SECURITY.md, docs/modules/harness/local-models.md
Project status, .rag scope, and integration-test links were updated.

Repository pointer updates

Layer / File(s) Summary
Vendored and wiki revision pins
vendor/tinyinference, wiki
Both subproject references now point to newer commits.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to d25a7

The README quick-start example is missing a direct tinyinference dependency even though the code imports it, so users following the documented setup may encounter a compile error; add the dependency or use a documented re-export before merging.

Poem

A rabbit reads the workspace guide,
With typed graphs hopping side by side.
The .rag paths shine clear and bright,
New pins settle the repo right.
Documentation blooms in morning light.

P1 Badge Keep TinyInference on the same Cargo source

When an external project copies this git-dependency block, Cargo loads two distinct tinyinference packages: the harness uses the path dependency inside the TinyAgents git checkout, while this entry uses the separate TinyInference repository. Consequently the harness example cannot pass its Vec<tinyinference::Message> to invoke_default, which expects the identically named type from the other package identity. Fresh evidence beyond the earlier missing-dependency report is a Cargo reproduction with the same git-submodule/path arrangement, which produces E0308 and reports multiple versions of the dependency; re-export these types or otherwise make consumers use the harness's package identity.

P2 Badge Describe .rag as producing only a Blueprint

For users expecting the documented lowering into runtime types, the available compiler APIs return tinyagents_language::Blueprint; this package has no tinyagents-graph dependency, and the referenced rag_blueprint example stops after validating capability names. The repository contains no exported build_graph/NodeFactory materialization API, so the claim that compilation produces the same graph and harness types as handwritten Rust is not currently actionable; document the Blueprint-only boundary or provide the missing materializer.
