Allowed advisor streams to treat Google STOP responses without visible content as successful silence while preserving the default retry behavior for interactive agents.
Added provider and advisor-path regressions covering retry counts, system instructions, and the advise declaration.
Fixes#8223
- seal() now runs before the final dispose close() and bumps the disk
epoch: work an event handler enqueues while dispose awaits the closing
tail is superseded, and an already-running fenced or authoritative
rewrite fails its commit guard at the rename fence instead of
publishing over a file a revival reopened.
- The authoritative repair path resets the disk tail itself, escaping the
close() serialization, and would atomically publish the emptied entry
list; it now no-ops once sealed and commit guards also check the seal.
- Execution-time gates cover the queued title persist and fenced rewrite
callbacks; setSessionName/appendCustomEntry attempted by a handler that
outlives dispose are dropped and covered by the seal regression, and a
failed atomic batch across the seal can no longer truncate the file.
- AgentLifecycleManager.park() resolves as soon as dispose() returns, so
ensureLive() may reopen the same JSONL through a new manager while a
timed-out event handler still holds the old one; a late append reopened
a second writer on that file and the deferred finalize then closed it.
- A post-release rewrite was worse: it persisted the emptied entry list,
truncating the transcript on disk.
- releaseRetainedEntries() now seals the manager: appends, title changes,
and rewrites become dropped no-ops and the append writer is closed, so
the deferred dispose pass is in-memory only and can never touch the file.
- File-backed regression: dispose on the drain deadline, revive the JSONL
immediately, unpark the late handler, and prove the file is byte-stable
and the revival writer owns it exclusively.
- The dispose drain deadline does not cancel in-flight event handlers: one
parked in a slow extension hook resumed after close/release, reopened the
append writer for its late persist, and repopulated the released state.
- Track whether the drain settled; on deadline, redo the final close +
release once the pipeline genuinely settles (hook runtime is bounded by
the extension runner).
- Expose drainTimeoutMs on AgentSessionDisposeOptions for bounded teardown
paths and deterministic coverage of the deadline branch.
- Added account-scoped policy error detection to correctly identify Codex cyber-policy rejections.
- Updated credential storage and retry logic to route denied accounts through sibling rotation instead of bypassing it.
- Ensured coding-agent sessions exhaust all sibling accounts before falling back on cyber denials.
- Added comprehensive test coverage for credential rotation and retry behavior on policy errors.
agent-core dispatches the session's event subscriber fire-and-forget (agent.ts #emit), so a message_end/agent_end handler can still be awaiting extension/subscriber/maintenance work — and its sessionManager/agent.state append — after agent.waitForIdle() resolves. The earlier settle waited only on the core run, so a late handler could append the finished message/entries back into the disposed session and re-pin the transcript.
Track every #handleAgentEvent dispatch in #inFlightEventHandlers and drain it (alongside agent.waitForIdle) inside the bounded settle before reset/clear/release. Added a regression test using a real extension whose message_end hook blocks before persistence, asserting dispose does not release memory until the in-flight handler settles.
dispose() only *signalled* the agent loop via abort(); it never awaited the run, so a mid-turn dispose (Ctrl-C/timeout/hard-killed subagent) could let the loop unwind after the release ran — its response/SSE interceptors re-recording wire frames into rawSseDebugBuffer and its terminal message re-appending to agent.state.messages, repopulating the disposed session with exactly the retained state the release drops.
Detach the response/SSE interceptors and await a bounded agent.waitForIdle() before the reset/clear so it lands on a quiescent session. Added a deterministic regression test that gates the active turn and asserts dispose blocks on it before clearing.
Disposed sessions remained reachable through lifecycle reviver closures. Agent.reset() cleared the live message array but left AppendOnlyContextManager attached, retaining its normalized provider transcript and stable prompt/tool prefix.
Detach the append-only manager during terminal disposal and extend the memory-release regression test to cover that second transcript copy.
Keep-alive subagents are handed to AgentLifecycleManager.adopt, which stores
their reviver closure in the process-global #adopted map. The closure is
defined inside runSubagent's scope, which also captures the live AgentSession
(extension-runner callbacks, buildSubagentSessionOptions), so its lexical
environment pins the whole session graph. park() disposes and detaches the
session but leaves the adoption record indefinitely, and #doDispose never
dropped the in-memory transcript, session-manager entries, or the raw-SSE
debug buffer (whose trimmed records retain slice() views of full wire frames),
so every completed subagent's heavy state leaked for the process lifetime.
dispose() is terminal and every revival path reopens from disk, so #doDispose
now sheds retained conversation memory via agent.reset(),
RawSseDebugBuffer.clear(), and SessionManager.releaseRetainedEntries(). The
adoption record can still reference the session, but only as a husk.
Fixes#8003
Harness-initiated session aborts previously cancelled compaction before the handoff reason was recorded. The handoff catch then saw only an aborted signal and replaced the harness reason with "Handoff cancelled".
Abort the handoff first with the session reason, forward caller-signal reasons, and reserve "Handoff cancelled" for direct or unreasoned cancellation. Add a regression test for an in-flight handoff aborted through AgentSession.abort.
Fixes#7993
The #7904 fix stopped masking provider errors as "Handoff cancelled", but
an empty or whitespace-only generation still fell through: whitespace-only
text passed the `!handoffText` guard and produced a bogus handoff, while
empty text returned undefined which the interactive /handoff caller mapped
to "Handoff cancelled" with no detail and no log entry.
Treat empty/whitespace-only output as a real failure: a user-initiated
handoff throws "Handoff generation produced no content" (surfaced as
"Handoff failed: ...") and logs it; auto-handoff keeps returning undefined
so maintenance falls back to context-full compaction. Also log genuine
handoff failures in the command controller so they persist for debugging.
Fixes#7993
- Separated deterministic replacement generation, placeholder derivation,
placeholder-range scanning and message-tree transforms out of the 2647-line
module; obfuscator.ts now holds the types and SecretObfuscator.
- ephemeralPlaceholderKey stays a single instance and both global regexes stay
beside the code that resets their lastIndex, so placeholder stability and
the security argument in the moved comments are preserved verbatim.
- Repointed every importer at the real modules rather than leaving a re-export
shim; the public ./secrets barrel exports the same 15 names as before.
- A provider-supplied retry-after now bypasses the transient rate/concurrency
heuristic window instead of being overridden by it (regression from the
subscription-cap retry change).
- Updated event-controller/ui-helpers test doubles for provenance-gated
renderer selection (hasBuiltInTool), aggregated retryErrors on
auto_retry_end, and Bedrock override compat gaining streamIdleTimeoutMs.
A cooldown-expiry model revert runs at a turn boundary. The user-prompt
path reverts then re-checks accumulated context against the restored
model via runPrePromptCompactionIfNeeded, but the automatic
agent.continue() path (#scheduleAgentContinue) reverted and issued the
next request with no such check. When a transient failure had fallen
back to a larger-window model and the conversation then grew past the
original model's window, restoring the primary once its cooldown expired
sent a predictably oversized request to the smaller model.
maybeRestoreRetryFallbackPrimary now reports whether it actually
switched, and the auto-continue path runs the same post-revert
context-fit maintenance (compaction/promotion) the prompt path already
runs, but only when a revert occurred.
Fixes#7952
The handoff catch in session-handoff.ts and the /handoff handler in
command-controller.ts mapped any error named AbortError to "Handoff
cancelled" regardless of whether the handoff signal was actually
aborted. Providers throw name-AbortError errors on non-user conditions
(stalls, idle timeouts, nested resolution failures), so a genuine
generation failure surfaced as a user cancellation and hid the cause.
Only report "Handoff cancelled" when handoffSignal.aborted is set;
re-throw the real error otherwise. The controller now trusts the
normalized "Handoff cancelled" message and drops its own AbortError
check so re-thrown provider failures render as "Handoff failed: ...".
Fixes#7903
The isAwaitingUserAnswer guard that suppresses the todo completion reminder while the agent waits on a user question only recognized English question words and pronouns. A '？'/'?'-terminated Chinese, Japanese, Korean, or Spanish prompt went undetected, so the <system-reminder> interrupted the pause and the model misread it as the user's answer.
isQuestionPromptLine now also treats a question-mark-terminated line containing any non-ASCII character as a pending user question.
Fixes#7803
The per-turn systemPrompt returned by before_agent_start was applied only to the agent state, so any base-prompt rebuild firing in the prompt window (context-overflow compaction/promotion, memory promotion, MCP/RPC tool refresh, hindsight MM-TTL refresh) re-pushed the rebuilt base via setSystemPrompt and silently dropped the override before the request.
SessionTools now tracks the active per-turn override and re-applies it on every base rebuild during the turn, clearing it when the turn ends.
Fixes#7755
- Bounded rewind report recovery to messages created after the active checkpoint.
- Added resumed-context regression coverage for late stale rewind results.
Fixes#7739
The ExtensionAPI getAllTools() wired to session.getAllToolNames(),
returning bare tool-name strings. Upstream @earendil-works/pi-coding-agent
promises ToolInfo[] with sourceInfo, so extensions loaded through the
legacy-pi shim (e.g. gentle-pi) crashed on t.sourceInfo.source at every
session start.
Added SourceInfo/ToolInfo types plus SessionTools.getAllToolInfos(), which
returns { name, description, parameters, sourceInfo } and classifies each
tool as builtin/mcp/sdk/extension. Rewired every getAllTools action site
(interactive, acp, print/rpc, subagent executor) and the example extension.
Fixes#7732
- Implemented in-house, zero-dependency utility modules in `pi-utils` covering DOM manipulation, markdown parsing, templating, browser automation helpers, and terminal buffers.
- Migrated packages across the repository to consume the new internal utilities and `omptype` schema validators instead of external dependencies.
- Removed multiple external runtime and development dependencies including Zod, Marked, LRU cache, Turndown, and Puppeteer browser packages.
Registered live session resume commands with postmortem handling so a
fatal rejection or exception identifies every recoverable agent before
cleanup. Escaped terminal control characters in recovery output.
The 17.2.9 revert (172ce9b) restored the legacy path-based session
directory names but removed all migration, including the reverse path.
Sessions written under the short-lived hashed scheme (17.2.5-17.2.8,
`<scope>-<readable>-<sha256>`) were left orphaned, so `omp -r`
current-folder scope reported no sessions.
computeDefaultSessionDir now reconstructs the hashed dir name for the
cwd and performs a one-way best-effort migration into the legacy name,
alongside the existing legacy-absolute migration.
Fixes#7677
Reset-window rotation requires account-specific wording; concurrency caps require an actual cap signal; credential removal gated on AuthFailed without UsageLimit so a valid-but-blocked 403 credential is retained.
(cherry picked from commit 2f72752c2586352a4f7e9e814af1cdb0cf192af4)
Account-reset hint evaluated before short retry hints; account-scoped caps rotate on status 403 or undefined (Devin statusless trailer); statusless concurrency caps marked transient; transient same-model retries use the concurrency backoff.
Refuted: quota-worded concurrency caps were already excluded from rotation before the usage-limit text match.
(cherry picked from commit f2b9a18d715ddbcb6ae703670f2212da36bb2826)
