On Terminal-Bench captures of DeepSeek V4 Flash (207 attempts), a +median of 14 model calls passed between plan updates, and half the attempts +that wrote a plan ended with steps still open. The block puts the current plan +and the hard facts at the tail of every request. + +## What it shows + +| Section | Source | Rule | +|---|---|---| +| Goal | `goals::store` for the run's thread | One line: status (active with budget left, paused, budget exhausted, complete) and the objective. | +| Plan | `todos::store` for the run's thread | Every step with its mark (`[x]` `[>]` `[ ]` `[-]`), the step in progress and the tool rounds it has run. At most 20 steps. | +| Recent failures | `after_tool` results with `is_error` | The last 3, each with its age, tool, command (or argument summary) and the exit code plus first `[stderr]` line. Dropped after 4 rounds, or when the same command later succeeds. Exit codes 1, 2 or 141 with no `[stderr]` line from a search or compound command (including pipelines and multi-line scripts) are treated as exploration misses and omitted. | +| Reported not found | Shell wording in error output (`X: command not found`, `sh: 1: X: not found`, `command not found: X`) | Cleared when a later successful command runs `X`. | +| Files written this run | Paths extracted from filesystem tool calls, patch envelopes and unified-diff headers | The last 6, distinct. | + +No section is ever a model's interpretation, so nothing in the block can be +wrong in a way the tool results are not. With no goal, plan or fact, no block +is added. + +## Placement and caching + +The block is added in `before_model_dispatch` through +`push_ephemeral_instruction`, and re-added in `after_model_rewrite` if a +request rewrite removed it or later guidance followed it. It therefore follows the model profile's +placement rules (a tail system message, or a `[harness note]` on the last tool +result or user turn for providers that hoist system messages), and is never persisted. It is included in the admission estimate when `BudgetMiddleware` runs after dispatch staging. `after_model_rewrite` also moves it back to the +end when a middleware pushed its own note after it in `before_model` (which runs after +`before_model_dispatch`), so the block is always the last thing the model reads: the next request is rebuilt from +the transcript, so the previous block is simply absent and the provider's +cached prefix is untouched. + +## Wiring + +```rust +use tinyagents_harness_tools::state_block::StateBlockMiddleware; + +harness.push_middleware(Arc::new(StateBlockMiddleware::new(todo_store))); +``` + +Enable the crate's `state-block` feature to use this module. + +For a run with no thread id, `with_fallback_thread(key)` names the scope the +host's `todo` tool falls back to (OpenHuman: the session id), so a headless run +still sees its plan. Pass the store the goal and `todo` tools write (in OpenHuman both live in the +session key-value store). Install it on the turns that have +the `todo` tool; it is an observer, so another middleware's control outcome +never hides a call from its ledger. Per-run state is keyed by the run +instance and dropped in `after_agent` / `on_error`. diff --git a/crates/tinyagents-harness-tools/src/state_block/ledger.rs b/crates/tinyagents-harness-tools/src/state_block/ledger.rs new file mode 100644 index 000000000..40ffdcb9d --- /dev/null +++ b/crates/tinyagents-harness-tools/src/state_block/ledger.rs @@ -0,0 +1,327 @@ +//!

The host implements session checkout and fingerprint +validation, supplies origin metadata, executes the turn, and checks the +session back in. Separate ports own ingress policy, reply persistence, +progress and terminal delivery, failure classification, and grounded closing +or suggestions. + +Ingress policies run in a fixed order: stage attachments, apply the guardrail, +intercept approval replies, then run before-submit hooks. A consumed approval +reply or a policy rejection never starts a turn. The runner owns TinyAgents' +`RunQueue` and its Steer, Followup, and Collect lanes. Accepted work retains +its generic, typed host payload in that queue; Followup requests dispatch as +fresh turns after the current turn completes. Steer requests still pending at +that boundary also dispatch as fresh turns, so an accepted steer cannot be +lost after host execution has stopped. `Interrupt` cancels the prior +primary generation; `Parallel` uses a host-created fork session and a separate +request-scoped cancellation slot, without serializing against the primary. + +Primary sessions serialize by `(agent_id, profile_id, thread_id)`. The active +slot is installed before waiting for that lock, so an interrupt can stop the +current owner and stale cancellation ids cannot stop its replacement. +Host-authored turns use the same session checkout and reply store but never +occupy the user cancellation slot. Hosts own session identity and checkout, +including fork isolation for parallel runs, and must check a session back in +after every successful checkout. The runner persists a deterministic reply +id before emitting exactly one terminal event. + +The idle guard defaults to 900 seconds and resets on progress. Hosts signal +`WorkStarted` and `WorkFinished` around model or tool work so a quiet but +healthy request is not treated as idle. The optional wall deadline remains a +separate total ceiling. Either guard cancels child work and asks the +`Summarizer` for a bounded grounded close before classifying the turn as failed. + +`AgentProgress` is the canonical channel-independent progress vocabulary. +Hosts translate it to their own event wire format; this module does not define +channel event names or transport payloads. diff --git a/crates/tinyagents-harness/src/turn_runner/mod.rs b/crates/tinyagents-harness/src/turn_runner/mod.rs new file mode 100644 index 000000000..52a0fda09 --- /dev/null +++ b/crates/tinyagents-harness/src/turn_runner/mod.rs @@ -0,0 +1,19 @@ +//!
