Generation offers active registered tools through positional system entries and
hands a tool-calling answer to parallel or sequential pi.tool tasks and a
pi.post-tools task that applies addTools/terminate and continues the run. Tool
tasks validate, run beforeTool/afterTool, record intent with the replay policy,
publish bounded, sanitized, adaptively throttled progress in pi.live.tools, and
write results with a rendered diagnostics block. Hook dispatch with conversation
and subtree scopes, prepareArguments, HarnessOptions.env, and read/bash/edit/write
tools in pi-durable/tools. The env shell now streams raw output and spills past
thresholds; its bounded capture and publisher are removed.
Durable generation imports retry helpers from pi-ai/utils/retry; examples use
pi-ai/models and pi-ai/providers/faux. Entry graph budgets and an import
footprint test guard the models entry.
Submissions with request-ID deduplication and handles, the pi.live run
control and presentation document, the built-in pi.generation task
(system prompt preparation, streamed durable partials, retries, deferred
polling, abort), typed entry tokens, stream options and retry policy,
TaskRuntime reads, Tx.settleSubmission, registry conversation setups,
Storage.scanSubmissions, Harness.inspect, and byTaskId attribution.
Waiting calls enable scheduling. The scratch tour is split into
test/examples.
