Composes #80465's pin semantics with #80438/#80421's
delegation.fallback_providers semantics (#65038) and settles the
composition cell the three PRs leave undefined (#80450 map).
_resolve_child_fallback_chain implements the whole decision table in
one pure function: pinned children get no chain unless the delegation
section declares one (a delegation-scoped chain honors both explicit
intents; the silent drag in #80450 is specifically the PARENT chain
substituting a pin); an explicit empty list disables fallback; absent
config preserves historical parent inheritance exactly. Malformed
declared values log and fall back PIN-AWARE — never the parent chain on
a pinned child, so the config-error path cannot reintroduce the drag.
Entries normalize through the canonical get_fallback_chain.
The two existing inheritance tests are made hermetic against the real
user config (as #80438 also did).
test_nous_anthropic_fallback_uses_the_messages_wire and
test_nous_child_rederives_api_mode_from_model describe the native wire, which
is now opt-in; select it in the test the same way the wire-contract suite
does, so both keep guarding the flip-back.
A subagent whose loop gave up on a structured failure (e.g. "API call
failed after 3 retries: HTTP 524") returns that error message as
final_response together with completed=False / failed=True /
failure_reason. _run_single_child derived the batch-entry status from
the summary alone (`elif summary and not _empty_sentinel: status =
"completed"`), so the non-empty error text made the batch report show
the task as "✓ status=completed" — the `failed` flag was never
consulted anywhere in delegate_tool.py. Only the "(empty)" sentinel was
mapped to failed.
Fix, at the single status-determination choke point both the single-task
and batch paths share:
- `failed=True` on the child result now wins over a non-empty summary:
status = "failed".
- The child's classified failure_reason (rate_limit / billing /
server_error / ...) is propagated onto the batch entry so the parent
can tell a quota wall from a real task error without parsing prose.
- exit_reason for a structured failure is "error" instead of falling
through to "max_iterations" (which also wrongly set truncated=True).
Successful children (completed=True, no failed flag) are untouched —
covered by an explicit control test alongside the regression test,
which is red on the old code and green with the fix.
Per-finding verdicts from the cross-vendor review of fix/status-fix
(#97655/#97654):
[1] Flash NIT (real, cheap) — FIXED. Added test_error_without_failed_flag_
marks_failed: an error string with the 'failed' key ABSENT (not False)
must still be status=failed + exit_reason=error. The branch order
(result.get('failed') or result.get('error')) already handles this; the
test pins the error-alone path.
[2] GPT-OSS SHOULD-FIX — PINNED. Added test_empty_error_with_summary_is_
completed: error='' is falsy so result.get('error') falls through to the
summary-presence heuristic => status=completed. No code change; the
existing branch is correct and the new test locks it in.
[3] GPT-OSS SHOULD-FIX — VERIFIED, NO CHANGE. Grepped every delegation
exit_reason consumer:
* tools/delegation_live_log.py finalize() prints exit_reason generically
and only special-cases == 'max_iterations' for a readable suffix.
* tools/process_registry.py derives truncated as
(truncated or exit_reason == 'max_iterations') — gated, not exhaustive.
* tools/async_delegation.py passes exit_reason through generically.
The gateway/status.py, cron/scheduler.py and run_agent.py 'exit_reason'
hits are a DIFFERENT field (turn_exit_reason / gateway exit reason), not
the delegation result's exit_reason. No exhaustive if/elif over the enum
missing an 'error' case, so nothing to add.
[4] GPT-OSS NIT — DONE. Enriched _run_single_child's docstring to enumerate
status in {completed, interrupted, failed} and exit_reason in {completed,
max_iterations, interrupted, error}, and added a compact enum comment at
the result-entry construction. Verified the process_registry.py renderer
comment (truncated <= exit_reason == 'max_iterations') still holds — the
truncation flag is derived exactly that way, so no contradiction.
[5] GPT-OSS NIT — REJECTED. The proposed 'fallback for legacy dicts that
explicitly set failed=False' is not adopted. No consumer produces a result
dict with an explicit failed=False and no summary while relying on
completed semantics: run_agent.py sets failed=True only on genuine failure
and omits the key on success (no failed=False producer). Also, the
proposed elif would reintroduce ambiguity (explicit failed=False + no
summary => 'completed'?) and diverge from the conservative else => 'failed'.
result.get('failed') is falsy for both explicit-False and absent, so no
distinction exists to preserve; the else is the correct default.
Tests: 301 passed, 7 skipped (tests/tools -k 'delegate or process_registry').
TestDelegateFailedChildStatus: 6 passed.
A provider-rejected child (e.g. HTTP 400 "<model> is not a valid model ID")
returns completed=False with failed=True + an error string as its terminal
final_response. _run_single_child keyed status on summary presence alone and
assumed completed=False meant iteration-budget exhaustion, so such a child
was reported status=completed + exit_reason=max_iterations, rendering the
false '"TRUNCATED: hit max_iterations"' banner.
Consult the structured failure fields (failed / error) before falling back to
the summary-presence heuristic, and derive exit_reason honestly: failure ->
'error', interrupted -> 'interrupted', completed -> 'completed', and only
genuine budget exhaustion (completed=False, no failure) -> 'max_iterations'.
The 'truncated' flag stays keyed on exit_reason == 'max_iterations', so it is
now correct automatically. The batch renderer needed no change (the error
field is already plumbed into the result entry for the parent).
Closes#97655
A delegate_task child that died (provider 404/400, timeout, crash)
previously vanished silently: the child's conversation loop returns
failed=True with the error summary in final_response, which the
classifier treated as usable output -> status 'completed'. And even
correctly-failed children only reached the parent MODEL — platforms
with tool_progress off (Telegram/Slack defaults) never showed the
human anything.
- delegate_tool: result.failed now forces status 'failed' (with the
error carried on the entry); new shared format_subagent_failure_line()
renders one clean human-readable line (traceback -> exception message,
length-capped); CLI tree + batch ✗ lines now include the reason.
- gateway TurnRunner.progress_callback: subagent.complete events with a
terminal failure status deliver that line via _deliver_platform_notice
BEFORE all progress-queue gates; tool_progress_callback is now always
attached (body gates each event class itself).
- tests: failed-flag classification regression + notice rendering suite.
- docs: Failure Visibility section in delegation docs.
When delegation.provider/model is explicitly pinned, the child no longer
inherits the parent's fallback chain: a mid-run auth/429 failure on the
pin previously rerouted the quiet-mode child onto parent fallback models
with no surfaced signal. Same treatment as the existing override_provider
OpenRouter filter-clearing — explicit pins are honored or fail loudly.
Also upgrades the pinned delegation.command-missing-from-PATH case from
warning + silent transport fallback to a loud spawn refusal, both at
credential preflight and in _build_child_agent.
Fixes#80450 (tracker #79686 audit item).
A bare SessionDB() resolves the launch profile's default state.db, but
parents can hold non-default per-profile handles (tui_gateway opens
SessionDB(db_path=<profile_home>/state.db) for non-launch profiles and
hands them to agents via _transfer_db_to_agent). A child of such a
parent would write its transcript into the WRONG database — cross-
profile leakage that breaks parent_session_id lineage and
session_search. Open the dedicated handle at the parent handle's
db_path instead (AsyncSessionDB forwards .db_path via __getattr__, so
the gateway wrapper path works too). Regression test verified RED on
the pre-fix code.
Review follow-up (cc3f18197): if AIAgent() raises inside _build_child_agent
the freshly-opened dedicated handle has no owner and no child close() will
ever run — release it on the exception path so the sqlite fds don't
outlive the failed spawn. Also pin the degradation contract with a test:
a parent without a SessionDB still yields session_db=None children.
Cron run_job closes its per-job SessionDB in its finally block while a
fire-and-forget background delegation subagent is still flushing on a
daemon thread. The child shared the parent's SessionDB object, so every
subsequent flush hit the closed handle ('NoneType' object has no
attribute 'execute') and the child's whole transcript was silently
dropped. The same teardown-while-child-alive shape exists on gateway
session end and /new mid-delegation.
Each child now opens its own SessionDB connection (owned flag set at
construction so child.close() releases it), so no parent teardown can
close the child's handle out from under it.
Regression test proves the child gets a distinct live handle that
survives the parent's close().
Reject malformed tasks=[...] batches before any child agent is spawned:
- exact-duplicate goals (case/whitespace-normalized), error names both
task indices
- placeholder goals: bare 'TODO', bare 'task N', unexpanded <...> or
{...} template markers, or goals shorter than 10 chars after strip
- 1-task batches, with an error pointing the model at the single
`goal` form instead
All checks are batch-only — the single-goal form is exempt by design
(short goals like goal="test" are valid there). Error strings are
actionable: each tells the model exactly how to fix the call.
Tool schema is unchanged (byte-stable); validation is runtime-only in
the existing batch-validation region.
Existing tests using terse batch goals ("A"/"B"/"C") updated to
realistic distinct goals per the new contract.

Top-level delegate_task runs in the background, and the 450s progress-stall
monitor only sees api_call_count / tool / last_activity_ts. Subagents use
non-streaming direct_api_call, which previously touched activity once and then
went silent — so a healthy local GGUF / long-prefill wait looked frozen and
was interrupted around ~450s as "Operation interrupted: waiting for model
response", even when child_timeout_seconds was raised. Refresh activity while
the inline request is open, and treat last_activity_ts advances as sync
heartbeat progress too.
The top-level delegate_task description repeated content the model already
receives through parameter descriptions: the concurrency limit (tasks param),
the full nesting clause (role param), context-passing guidance (goal/context
params), and background semantics (background param). Every API call paid for
the duplication (~4,000 chars).
The description now carries only what exists nowhere else in the schema:
use/don't-use routing (execute_code, cronjob), the no-poll rule, the
non-durability warning, the self-report verification contract with concrete
verbs, the language-passing example, the leaf blocked-tool list, and model
inheritance. 3,963 -> 1,704 chars (~570 tokens saved per API call), and the
top-level text is now static (dynamic limits flow only through the two param
descriptions, which are already rebuilt per get_definitions() call).
A/B benchmark across 4 models (gpt-4o, gpt-4o-mini, claude-haiku-4.5,
llama-3.3-70b) showed the naive compaction in PR #72813 regressed weaker
models on exactly the passages it cut (side-effect verification 8/8->0/8 on
gpt-4o-mini; language passing 3/3->0/3 on haiku-4.5). This version keeps
those benchmark-sensitive hooks verbatim.
Tests pin the contracts at keyword level (not prose-literal) plus a size
ceiling, and verify dynamic limits still reach the model via the tasks/role
param descriptions.
Refs #72737, supersedes the delegate_task half of PR #72813.
Second, deeper pass over tools/gateway/hermes_cli plus first pass over
the trees wave 1 missed (acp, acp_adapter, skills, computer_use, docker,
dashboard, conformance, monitoring, secret_sources, hermes_state,
providers). Same rubric as wave 1 (AGENTS.md test policy); security,
alternation/caching invariants, issue-number regressions, and E2E kept.
Real test-quality fixes found and rooted out along the way:
- tests/tools/test_command_guards.py made real auxiliary-LLM HTTPS calls
(DEFAULT_CONFIG smart-approval leaked in) — pinned approval
mode=manual via autouse fixture: 17.4s → 0.4s.
- test_model_switch_custom_providers.py / test_user_providers_model_switch.py
silently probed live provider catalogs (~2s/test) — stubbed
cached_provider_model_ids/provider_model_ids/fetch_api_models.
- test_telegram_noise_filter.py: 15-platform copy-paste matrix over
shared gateway.run logic → 3 representative platforms (55s → 3.9s).
- test_gateway_shutdown.py: stop()'s 5s interrupt-deadline loop spun on
MagicMock agents — interrupt.side_effect now clears _running_agents
(22s → 1.0s).
- test_gateway_inactivity_timeout.py poll-harness timings shrunk 3-5x
(24s → 1.1s); test_mcp_stability.py backoff/SIGTERM-grace sleeps
patched (15.4s → 2.5s); test_async_delegation.py negative-drain wait
5s → 0.5s.
- test_telegram_init_deadline.py: loop-block margin restored to 1.0s
with rationale comment — the watchdog-dump assertion needs the loop
blocked well past deadline+grace under parallel load (flaked once in
the 40-worker verification run at a 0.2s margin).
Verification: full hermetic suite via scripts/run_tests.sh —
2,438 files, 21,718 tests passed, 0 failed, 293.9s wall.
Suite totals vs original baseline: 46,820 → 19,757 test functions
(−57.8%), wall 583.5s → 293.9s (−50%), subprocess CPU 13,564s → 11,623s.
Children inherit the parent's env, repo, and toolsets but were denied
execute_code ('children should reason step-by-step, not write scripts').
That forces subagents doing mechanical multi-step work (batch file
reads, fetch-N-pages loops, filter-before-context reductions) to burn
reasoning iterations one tool call at a time.
- Remove execute_code from DELEGATE_BLOCKED_TOOLS
- Stop stripping the code_execution toolset from child bundles
- No recursion risk: the sandbox bridges only the 7 SANDBOX_ALLOWED_TOOLS
(web/file/terminal) — delegate_task and execute_code itself are not
reachable from inside a sandbox script
- Update schema text, AGENTS.md, and delegation docs
- Tests: blocked-constant, strip, and child-assembly tests updated;
new test pins execute_code as intentionally unblocked
A leaf subagent is meant to be denied delegate_task, execute_code, memory,
clarify, cronjob, and send_message. _strip_blocked_tools() only drops a
toolset when EVERY tool in it is blocked, so mixed platform bundles
(hermes-cli, hermes-telegram, and every other gateway bundle) survived
stripping and re-exposed the blocked tools after composite expansion. A
leaf child spawned from any gateway platform could recursively delegate,
run code, and write memory.
Pass exact one-tool deny toolsets into the child's disabled_toolsets so
model_tools subtracts the blocked names AFTER composite expansion, and the
restriction survives later registry/MCP refreshes. Orchestrators regain
only delegate_task.

test_build_child_agent_ignores_acp_command_when_binary_missing patches
shutil.which globally and asserted the LAST call was which("copilot").
That is order-dependent: an unrelated which("uv") reached later in the same
process (which happens under some CI test-slice orderings) becomes the last
call, so assert_called_with("copilot") fails even though the copilot binary
was probed exactly as intended. Switch to assert_any_call("copilot"), which
verifies the actual intent and is robust to unrelated which() calls. The
behavioural assertions (provider, acp_command, acp_args) are unchanged.

Remove acp_command and acp_args from the model-facing delegate_task schema and
dispatch paths. Child agents can still use ACP subprocess transport when it
comes from trusted delegation config or parent inheritance, but a model tool
call can no longer choose the command or arguments that reach child
construction.
This is salvageable because the risky boundary is model control over child ACP
transport, not ACP itself. The patch follows the maintainer direction from the
source discussion by preserving trusted ACP configuration and prior integration
work while removing the untrusted tool-call fields from both top-level and
per-task delegate inputs.
Reproduced on main by passing acp_command through delegate_task and observing it
reach _build_child_agent. Verified after the fix that model dispatch strips the
hidden top-level fields and per-task hidden fields are ignored before child
construction.

delegation.max_concurrent_children is now the single cap for both a
batch's parallelism and concurrent background delegation units.
- _get_max_async_children() delegates to _get_max_concurrent_children();
a leftover max_async_children key logs a one-time deprecation warning
- config v32→33 migration removes the stale key, folding a raised
max_async_children into max_concurrent_children (max wins, no lost
headroom)
- capacity error messages now point at max_concurrent_children
- pool-at-capacity sync fallback now attaches an explanatory note so
the model/user know why the call blocked instead of dispatching async
Previously users who raised max_concurrent_children (e.g. to 15) still
hit the invisible default-3 async cap: the 4th background delegate_task
silently ran inline, blocking the turn with no signal.
The model could pass `toolsets` (top-level and per-task) to delegate_task,
letting it choose which toolsets a subagent got. Toolset selection is a
capability-scoping decision the model should not control; subagents inherit
the parent's enabled toolsets, period.
- Remove `toolsets` from the delegate_task() signature, the registry handler,
the top-level + per-task JSON schema, and the live dispatch path
(run_agent._dispatch_delegate_task — this forwarded it on every model call).
- Single-task and per-task child builds now pass toolsets=None so
_build_child_agent resolves to pure parent inheritance.
- Drop the now-dead _SUBAGENT_TOOLSETS / _TOOLSET_LIST_STR schema-hint block.
- _build_child_agent keeps its internal toolsets param + intersection helpers
(internal API; fed the inherited value only).
- Tests: schema assertions flipped to assertNotIn; added a regression test
proving the dispatch path never forwards a smuggled model `toolsets`.
- Docs: update delegate_task signature refs in the autonomous-ai-agents skill.
Two related bugs caused subagent delegation to silently return empty summaries
with 0 tokens when the user configured delegation.provider=bedrock alongside
delegation.base_url=https://bedrock-runtime.<region>.amazonaws.com.
Root cause #1 — misrouting in _resolve_delegation_credentials():
The configured_base_url branch unconditionally forced provider='custom' and
api_mode='chat_completions', only specializing for chatgpt.com, anthropic,
and kimi hosts. Bedrock (and other native-SDK providers) fell through as
'custom' + chat_completions, which then POSTed OpenAI-shaped JSON at
Bedrock's native API. Bedrock rejected the payload and returned nothing,
which looked like an empty LLM response to the child agent.
Fix: when provider is one of {bedrock, vertex, google, google-genai}, skip
the base_url short-circuit and fall through to resolve_runtime_provider(),
which knows how to construct the proper SDK client. base_url can still be
forwarded through that path for regional overrides.
Root cause #2 — '(empty)' sentinel accepted as success:
After N retries of empty LLM responses, run_agent.py emits the literal
string '(empty)' as final_response. _run_single_child then hit
`elif summary:` — '(empty)' is truthy, so status became 'completed' and
the parent surfaced a blank result with no error. Users saw api_calls=4,
tokens=0, duration~0.4s, status=completed.
Fix: treat final_response.strip() == '(empty)' as a failure so the parent
surfaces it instead of silently accepting zero-content 'success'.
Both paths were reproduced in a live Hermes TUI session on us-west-2 Bedrock
(provider=bedrock, model=us.anthropic.claude-sonnet-4-6) and are covered by
new tests in tests/tools/test_delegate.py.
Defense-in-depth follow-up to the runtime guard added in the previous commit.
Models on headless hosts (Railway / Fly / Docker / fresh VPS) without any ACP
CLI installed occasionally hallucinate ``acp_command="copilot"`` from the
schema description, despite the explicit "Do NOT set" instruction. The runtime
guard prevented the crash but the model still wasted a tool turn and got an
opaque silent fallback.
This commit removes the temptation at its source: ``_build_dynamic_schema_overrides``
now strips ``acp_command`` and ``acp_args`` from both the top-level and per-task
schemas when none of the known ACP CLIs (``copilot``, ``claude``, ``codex``) are
detectable on PATH. The model literally never sees the fields, so it cannot
pass them.
The runtime guard from the previous commit stays in place as defense-in-depth
for internal callers, tests, and any future code path that bypasses the schema.
``_acp_binary_available`` is intentionally NOT cached: ``shutil.which`` is
cheap, and avoiding the cache means the schema reacts to mid-session installs
without requiring a process restart.
Tests:
- ``test_schema_prunes_acp_command_when_no_acp_binary``
- ``test_schema_keeps_acp_command_when_binary_available``
- ``test_acp_binary_available_checks_known_clis``
Full ``test_delegate.py`` suite: 136/136 pass.

When a model passes `acp_command="copilot"` (or any other binary name) in a
`delegate_task` tool call, `_build_child_agent` unconditionally sets
`effective_provider = "copilot-acp"`, which routes the subagent through
`CopilotACPClient`. That client spawns the named binary via subprocess; if it
isn't on PATH, every retry raises RuntimeError and an asyncio cleanup race
during error delivery can take the entire gateway down.
This is a real failure mode on headless deploys (Railway / Fly / VPS / Docker)
where `copilot` / `claude` / etc. aren't installed. The schema does say
"Do NOT set unless the user explicitly told you an ACP CLI is installed,"
but models occasionally pass it anyway — particularly for X (Twitter) search
prompts where Grok seems to associate ACP with "search assistance."
Reproduction:
- Headless install (no `copilot` binary on PATH)
- Set provider to xai-oauth + model grok-4.3
- Telegram prompt: "Search X for crypto twitter trends"
- Grok decides to delegate and passes `acp_command="copilot"`
- Subagent crashes 3x, gateway crashes on the 3rd retry teardown
Fix: validate the binary exists on PATH via `shutil.which` before honoring
the override. If missing, log a warning and fall through to the parent's
default transport. No behavior change when the binary IS present (covered
by `test_build_child_agent_honors_acp_command_when_binary_present`).
Tests:
- `test_build_child_agent_ignores_acp_command_when_binary_missing`
- `test_build_child_agent_honors_acp_command_when_binary_present`
Verified on Python 3.11 (macOS) and 3.12 (Debian 13 container).

Stabilize the long-running-tool heartbeat test by patching stale thresholds inside the test and asserting the heartbeat exceeds the idle ceiling, which preserves intent while removing scheduler-sensitive assumptions that flake in CI.
_strip_blocked_tools used a hardcoded set missing 'cronjob'. Children
on gateway platforms could inherit the cronjob toolset, scheduling
persistent jobs that outlive the delegation despite DELEGATE_BLOCKED_TOOLS.
Fix: derive the strip set from DELEGATE_BLOCKED_TOOLS at runtime so the
two lists can never drift. Add 'cronjob' to DELEGATE_BLOCKED_TOOLS for
documentation consistency. Two regression tests lock the invariant.
Salvaged from #43687 by @riyas22. Adapted test to current main (no
'messaging' toolset exists -- send_message is intentionally not
registered as an agent tool).
Closes#43466
* feat(desktop): stream subagent replies into watch windows
A desktop watch window resumes a child session lazily (no full agent) and
mirrors the parent-relayed `subagent.*` events into native child-session
stream events. The child's streamed reply text was never relayed, so the
window sat blank while the subagent "talked".
- delegate_tool: forward the child's `run_conversation` stream tokens up the
progress relay as `subagent.text` (inert under CLI/TUI — their progress
handlers ignore non-tool event types; only a gateway watch window mirrors it).
- server: mirror `subagent.text` -> `message.delta` on the child sid only, and
skip the parent emit (per-token frames are meaningless on the parent session,
which shows the child via the spawn tree). Demote `subagent.start` to a
one-time goal header and drop the noisy `subagent.progress` mirror — tools
already mirror natively.
- server: guard `_start_agent_build` so a lazy watch session spectating an
in-flight child stays lazy; incidental RPCs were upgrading it to a full
agent mid-stream and silently killing the mirror.
* fix(desktop): keep watch-window chat clear of titlebar chrome
Secondary windows (new-session scratch, subagent watch, cmd-click pop-out)
hide the titlebar tool cluster + session header, so the transcript ran to the
window's top edge and streamed text slid up under the OS traffic lights.
- Gate the hidden chrome on `isSecondaryWindow()` everywhere (app-shell,
chat header, thread list) instead of the narrower new-session flag.
- Add a fixed opaque drag-strip at the top of the secondary-window transcript:
content padding alone scrolls away with the text, so the strip masks
anything behind it and keeps the window draggable like the main header.
* fix: WSL subagent window
* fix: subagent window top padding

Subagents delegated to a custom endpoint were misrouted when the parent
ran on a different custom endpoint. Both runtimes collapse to
provider="custom", so _resolve_child_credential_pool() treated them as
interchangeable and handed the child the parent's pool. Leasing from it
then overwrote the child's delegated base_url with the parent's endpoint
via _swap_credential() — the child sent the delegated model name to the
wrong endpoint.
Custom runtimes now resolve by endpoint identity (the custom:<name> pool
key derived from base_url). The parent pool is reused only when both
parent and child resolve to the same custom endpoint; unregistered raw
endpoints return None so the child keeps its fixed delegated credential.
Non-custom provider paths are unchanged.
Fixes#7833.
Follow-up on the cherry-picked content-block fix. _extract_output_tail
(the live subagent overlay) still used crude str(content), which renders
a "[{'type': 'text'...}]" blob and — worse — mislabels a block-wrapped
"Error: ..." result as is_error=False. Route it through the same
_stringify_tool_content helper so error detection and previews work at
both consumer sites.
- delegate_tool.py: _extract_output_tail uses _stringify_tool_content
- tests: add _extract_output_tail content-block test (error detection +
clean preview)
- release.py: AUTHOR_MAP entry for randomsnowflake (CI gate)
* fix: respect disabled auto-compaction on context overflow
Port from anomalyco/opencode#30749.
When compression.enabled is false, NO automatic compaction trigger may
fire. The proactive token-threshold paths (preflight + post-response
should_compress gate) already honoured the setting, but the three
provider-overflow recovery paths in the agent loop — long-context-tier
429, 413 payload-too-large, and context-overflow — called
_compress_context() unconditionally, silently compressing and rotating
the session against the user's explicit choice.
Add a single guard at the top of the overflow-recovery dispatch: when
compression is disabled and the error is one of those three overflow
classes, surface a terminal error (compaction_disabled: True) telling the
user to /compress manually, /new, switch to a larger-context model, or
reduce attachments. Manual /compress (force=True) is unaffected — it never
enters this loop.
Tests: new TestOverflowWithCompactionDisabled (413 + 400 overflow don't
compress when disabled; control case still compresses when enabled).
Existing overflow-recovery tests updated to enable compaction explicitly
(they verify the recovery fires); fixture defaults flipped to True to
match production (compression.enabled defaults to True).
* feat(delegation): uncap max_spawn_depth to match max_concurrent_children
Removed the hard ceiling of 3 on delegation.max_spawn_depth. Depth now has
a floor of 1 and no upper limit, mirroring max_concurrent_children. Cost
(each level multiplies API spend) is the practical limiter, not a constant.
- delegate_tool.py: drop _MAX_SPAWN_DEPTH_CAP, _get_max_spawn_depth() floors
at 1 instead of clamping to [1,3]; depth-limit error string reworded
- config.py / cli-config.yaml.example: doc comments say floor 1, no ceiling
- docs (configuration, delegation, delegation-patterns): range 1-3 -> >=1
- tests: convert clamp-above-3 change-detector into a no-ceiling invariant,
drop the _MAX_SPAWN_DEPTH_CAP==3 snapshot assert, fix warning-text assert
Remove unused imports (F401) and duplicate/shadowed import
redefinitions (F811) across the codebase using ruff's safe
autofixes. No behavioral changes -- imports only.
- ~1400 safe autofixes applied across 644 files (net -1072 lines)
- __init__.py re-exports preserved (excluded from F401 removal so
public re-export surfaces stay intact)
- Re-exports that are imported or monkeypatched by tests but look
unused in their defining module are kept with explicit # noqa:
F401 (gateway/run.py load_dotenv; run_agent re-exports from
agent.message_sanitization, agent.context_compressor,
agent.retry_utils, agent.prompt_builder, agent.process_bootstrap,
agent.codex_responses_adapter)
- Unsafe F841 (unused-variable) fixes deliberately skipped -- those
can change behavior when the RHS has side effects
- ruff lints remain disabled in pyproject.toml (only PLW1514 is
selected); this is a one-time cleanup, not a config change
Verification:
- python -m compileall: clean
- pytest --collect-only: all 27161 tests collect (zero import errors)
- core entry points import clean (run_agent, model_tools, cli,
toolsets, hermes_state, batch_runner, gateway)
- static scan: every name any test imports directly from an edited
module still resolves
Addresses reviewer feedback: when resolve_runtime_provider returns a dict
without the 'provider' key, the result must be None regardless of
configured_provider. This guards against malformed runtime responses.
Test: test_runtime_missing_provider_key_returns_none
Named custom providers (e.g. crof.ai) resolve to provider='custom' at the
runtime level, causing subagents to lose their intended provider identity.
On retry/fallback, resolve_provider_client('custom', model=...) searches all
providers advertising that model and picks non-deterministically, routing to
Z.AI or Bailian instead of the configured target.
The fix preserves configured_provider when runtime['provider'] == 'custom',
restoring the original provider name so routing stays correct through retries.
Adds a named constant _RUNTIME_PROVIDER_CUSTOM instead of a magic string.
Adds three regression tests:
- test_named_custom_provider_preserves_provider_name: the #26954 case
- test_standard_provider_not_overwritten_by_configured_name: openrouter/nous
must still return their own identity, not the configured name
- test_custom_provider_with_empty_configured_provider_falls_back_to_runtime:
empty provider triggers the early-return None path as before
Subagent delegation hardcoded api_mode='chat_completions' for any
delegation.base_url that didn't match three specific hostnames
(chatgpt.com, api.anthropic.com, api.kimi.com/coding), and never
read delegation.api_mode from config. Azure AI Foundry's
https://foundry.services.ai.azure.com/anthropic endpoint fell through
and got chat_completions, causing 404s on every delegate_task call.
The main agent already handles this correctly via the shared
_detect_api_mode_for_url() helper (anything ending in /anthropic →
anthropic_messages); delegation reimplemented its own narrower check.
Reuse the shared detector and honor an explicit delegation.api_mode
when set so users can also force the transport on non-standard
endpoints the URL heuristic can't classify.
Fixes#10213.

acp_command / acp_args descriptions previously primed the model to
populate them — "Per-task ACP command override (e.g. 'copilot')" —
even when no ACP CLI was installed. Models with weaker schema-following
discipline would set them and the spawn would fail.
Add explicit "Do NOT set unless the user has explicitly told you"
guidance at both the top-level acp_command and the per-task override.
Strengthen acp_args to mention it's empty unless acp_command is set.
Adds 2 tests pinning the descriptions.
Note: this is a cosmetic prompt-engineering fix — the params remain
exposed in the schema. The fully-correct fix is to gate them behind
a config flag or runtime ACP-CLI detection so the schema only emits
them when an ACP harness is available. Tracked as a follow-up; this
PR ships the low-cost stopgap.
Salvage of #22680 (delegate schema only). The original PR also
bundled unrelated fixes for #22548, #21944, #22150 — those
need separate PRs since #22548 and #21944 are already addressed
on main (#22780 + #22798 in flight) and #22150 deserves its own
review.
Closes#22013.
The delegate_task tool description hardcoded 'default 3' / 'default 2' for
max_concurrent_children / max_spawn_depth, which misled the model on any
install that raised these limits — the schema text said 'default 3' even
when the user had set max_concurrent_children=15 / max_spawn_depth=3, so
the model would self-cap at 3 and never use the headroom.
Make the description dynamic. ToolEntry gains an optional
dynamic_schema_overrides callable; registry.get_definitions() merges its
output on top of the static schema before returning it. delegate_tool
registers a builder that reads the current delegation.* config and emits:
- 'up to N items concurrently for this user' (N = max_concurrent_children)
- 'Nested delegation IS enabled / OFF for this user (max_spawn_depth=N)'
- 'orchestrator children can themselves delegate up to M more level(s)'
- 'orchestrator_enabled=false' when the kill switch is set
The model_tools cache key already includes config.yaml mtime+size, so
edits to delegation.* in config invalidate the cached tool definitions
without an explicit hook. CLI_CONFIG staleness within a process is a
pre-existing limitation of _load_config and out of scope here.
Static description / tasks.description / role.description in
DELEGATE_TASK_SCHEMA are placeholders so module import doesn't trigger
cli.CLI_CONFIG load before the test conftest can redirect HERMES_HOME.
Recover delegate_task batch inputs when open-weight models emit tasks as a JSON-encoded array string, and return clear errors for malformed task lists.
