The two TestSourceGuardrail tests asserted the presence of literal
strings ("#58753", "_user_survives") in context_compressor.py. Those
are change-detector tests that break on any refactor without catching a
real regression. The four behavioral tests in
TestCompressAlwaysKeepsAUserTurn already exercise the real compress()
path and fully cover the invariant (user turn survives, summary pinned
to user, no consecutive user roles, surviving tail user untouched).
Regression coverage for the kanban-worker crash where compression left a
transcript with no user-role messages, triggering a non-retryable
`400 No user query found in messages` from vLLM/Qwen.
Exercises the real `compress()` path with the reporter's shape (no system
prompt in the list, a re-compaction with the only user turn in the
compressed middle) and asserts the output always keeps >=1 user turn,
never introduces consecutive user roles, and leaves a surviving tail user
message untouched. A source guardrail pins the guard so a future refactor
cannot silently drop it.
Compression could produce a transcript with ZERO user-role messages,
which OpenAI-compatible backends (vLLM/Qwen) reject with a non-retryable
`400 No user query found in messages`. This crashes `hermes kanban`
workers unrecoverably: every resume replays the same poisoned history and
fails on the very first request after a successful compaction.
The existing #52160 guard pins the handoff summary to role="user" only
when `last_head_role == "system"` — i.e. when the system prompt sits
inside `messages` (the gateway `/compress` path). The main
auto-compression path prepends the system prompt at request-build time,
so the list handed to `compress()` starts with a user/assistant turn,
`last_head_role` defaults to "user", and the summary is emitted as
role="assistant". A kanban worker seeded with a single short
`"work kanban task <id>"` prompt followed by nothing but assistant/tool
turns therefore ends up user-less once that early turn is summarised.
Generalise the guard: when no user-role message survives in the protected
head or the preserved tail, force the summary to carry role="user" so the
request always has at least one user turn. When a user does survive
(e.g. in the tail), the guard does not fire, so alternation is preserved.
Fixes#58753.
Add an opt-in toggle (require_admin_for_exec_approval, default false) that
restricts who can click Approve/Deny on a dangerous-command prompt to admins
listed in allow_admin_from. Off by default, so the v0.16-restored user-scope
behavior is unchanged. When on, the clicker must pass the normal admission
check AND be an admin; fails closed (logged) when no admins are configured.
Only ExecApprovalView is gated — model picker / clarify / update-prompt stay
user-scope.
coerce_tool_args only repaired the outermost value, so JSON-encoded
*elements* of array properties (and nested object sub-fields) were left
as strings. Three core tools have array<object> schemas — todo.todos,
delegate_task.tasks, memory.operations — so a model emitting
{"todos": ["{...}"]} would pass raw JSON strings into the tool and fail
downstream on item["id"]/item["goal"] access.
Adds a schema-guided recursive pass (_normalize_json_strings_for_schema)
that parses JSON-string array items and nested object fields only when
the matching schema position expects an array/object, preserving
legitimate JSON-looking string fields (type: string).
Adapted from cline/cline#11803 to hermes-agent's existing coercion layer.
Follow-up to the salvaged #58696 (devatnull) + #41343 (annguyenNous)
commits: instead of fully suppressing commentary/analysis-phase stream
deltas, fire on_reasoning_delta so the CLI/gateway display them like
thinking text. Matches Codex CLI semantics where commentary is never
the turn's final answer, while keeping the narration visible in the
reasoning display. Adds devatnull to AUTHOR_MAP.
GPT-5.x models on the Codex Responses API emit short pre-tool-call
"preamble" text as message items with phase="commentary". Previously,
_normalize_codex_response() added ALL message items to content_parts
regardless of phase, causing commentary text to leak as visible
assistant content on chat gateways.
Fix: when normalized_phase is "commentary" or "analysis", route the
message text to reasoning_parts instead of content_parts. This keeps
preamble/internal planning in the reasoning channel where it belongs.

- bridge: only enqueue poll_update events for polls Hermes itself created
(tracked via recentlySentIds when /send-poll returns) so arbitrary human
polls in group chats don't inject agent-visible messages on every vote
- update test_already_whatsapp_italic for the new markdown-italic mapping
- AUTHOR_MAP entry for @devatnull (PR #58704 salvage)
The SOM/AX element list dropped labels for two extremely common cua-driver
render forms, leaving the model unable to target elements by name:
- [79] AXButton (Dark) -> parenthesised label
- [4] AXStaticText = "Wi-Fi" -> = "value" form
- [92] AXPopUpButton = "Automatic" -> = "value" form
The old regex only matched quoted "label" and id=Label, so System Settings
buttons/text/popups all surfaced with empty labels. That's why selecting the
macOS Appearance 'Dark' button by element index required guessing — the
labels weren't available to aim with.
Fix: extend _ELEMENT_LINE_RE to capture all four label forms (= "value",
"quoted", (parenthesised), id=Label), skipping a pure-digit (N) order number
in favour of the id= label. Verified live against System Settings: the
Appearance buttons now surface as Auto/Light/Dark.
Adds a regression test covering all label forms. Full suite: 84 passed.
The first fix handled the EAGAIN McpError path. But the persistent MCP
session (long-running gateway/desktop worker) has a second failure mode:
list_windows or get_window_state 'succeed' over MCP yet return a
degenerate/empty payload (no windows, or no screenshot + blank tree)
WITHOUT raising — typically when the bridge reconnected mid-call and
dropped the heavy response. That surfaced to the model as a silent 0x0
capture with no error and no fallback firing (0.00s empty return).
Fix: detect empty results in capture() and re-fetch over the CLI
transport before giving up:
- empty list_windows -> CLI re-fetch the window list
- empty get_window_state (som/ax) -> CLI re-fetch the AX tree + screenshot
- empty screenshot (vision) -> CLI re-fetch get_window_state for the PNG
Adds 2 regression tests. Full suite: 83 passed.
The cua-driver MCP stdio bridge intermittently (and on some machines
persistently) fails to forward heavier calls like get_window_state to
the daemon with POSIX EAGAIN — 'daemon transport error forwarding
get_window_state: Resource temporarily unavailable (os error 35)'.
The wrapper surfaced this as an empty 0x0 capture, so computer_use
returned blank screenshots even though the display, permissions, and
the daemon were all healthy (the direct 'cua-driver call' CLI path
worked fine throughout).
Fix: when the MCP path raises the transient/transport error, fall back
to the 'cua-driver call' subprocess transport, which talks to the
daemon over a different socket. The CLI fallback routes get_window_state
screenshots to a temp file via screenshot_out_file (tiny JSON response
instead of a multi-MB base64 blob that congests the socket), reads the
PNG back, retries with backoff, and remaps the JSON into the same
{data, images, structuredContent, isError} shape the MCP path produces
so capture()/_action() are transport-agnostic.
Adds _is_transient_daemon_error() classifier and 3 regression tests.
Verified live: captures that returned 0x0 now return full
1567x905 screenshots with the AX element tree.
The 'never reached ready' error (issue #57025) was undiagnosable — doctor
and MCP test pass while the wrapper times out, with no hint where startup
stalled. Track a phase marker through _lifecycle_coro (binary-check →
manifest-discovery → mcp-initialize → capability-discovery → ready) and
include it in the timeout RuntimeError plus a pointer to doctor and the
agent.log phase timings.
Complements the 15s→30s bump + success-path phase timing log from #58760.
Replaces the POSIX `/bin/bash -c "$(curl …)"` invocation with a
download-then-exec flow: curl the upstream install.sh into a mkstemp
temp file (unpredictable name, 0600) and run it as a plain argv list.
No shell=True, no command substitution. The temp script is removed in
a finally block; download failures return cleanly without exec.
Salvages the intent of #34974 by @ErnestHysa. His original patch
targeted a fixed /tmp/cua-driver-install.sh path (symlink/TOCTOU-prone
on multi-user hosts) and predates Windows/Linux installer support;
this version uses mkstemp and keeps the powershell path untouched.

Follow-up to #57987: after /skill-a the completer previously went silent
for a second /skill token. Now, while the leading tokens form an unbroken
skill chain (each token a distinct installed skill, under the 5-cap) and
the word under the cursor starts with '/', the completer keeps offering
the remaining skill commands, and SlashCommandAutoSuggest ghost-suggests
the rest of the next skill name. Instruction text, path-like tokens, and
broken chains get no suggestions. The TUI's complete.slash RPC reuses
SlashCommandCompleter, so it inherits the behavior with no changes.
/model switches, primary-model fallback, and credential-pool key
rotation all change the prompt-cache key (model and/or account), so
the next turn re-reads the entire conversation at full input price.
Add cost warnings everywhere docs recommend or describe these paths:
- reference/slash-commands.md: cost note on both /model rows

* fix(cli): unwedge cua-driver installer timeouts — group-kill on timeout, stale-lock pre-clear, 660s ceiling
The cua-driver refresh in hermes update could wedge permanently:
subprocess timeout (300s) killed only the outer shell, orphaning the
curl|bash grandchildren and the upstream installer's concurrent-install
lock (~/.cua-driver/packages/.install.lock.d). The installer only
reclaims a stale lock after 600s of waiting — longer than our old
ceiling — so every subsequent run was killed before recovery could
fire: 'always times out'.
- Run the installer in its own process group (start_new_session) and
SIGKILL the whole group on timeout, so no lock-holding orphans survive.
- Pre-clear a provably-stale lock (dead holder pid, or pid-less and
older than the upstream 600s window) before invoking the installer.
- Raise the ceiling to 660s (> upstream LOCK_STALE_AFTER_SECONDS=600).
- Timeout message now names the lock path and the manual re-run command.
Fixes#58762
* chore: suppress windows-footgun lint on platform-gated kill calls
Both sites are POSIX-only: _clear_stale_cua_install_lock early-returns
on win32, and os.killpg sits in the 'not is_windows' branch.
On Windows, the cua-driver MCP session initialization can exceed the 15s
timeout due to manifest subprocess discovery + MCP transport setup.
This makes the computer_use tool permanently unavailable even though
hermes computer-use doctor and hermes mcp test both pass.
- Increase _ready_event.wait timeout from 15s to 30s
- Add startup timing instrumentation (manifest + mcp_init durations)
- Log timing at INFO level for diagnosability
Fixes#57025
The salvaged #54550 converted AIAgent._build_keepalive_http_client but the
near-identical build_keepalive_http_client in agent/process_bootstrap.py
(used by auxiliary clients: compression, vision, web_extract, titles) kept
the socket_options transport and the api.githubcopilot.com bypass. Same
conversion: httpx.Limits(keepalive_expiry=20) + pool timeouts, verify
forwarded on client and no-proxy mounts, copilot hardcode removed.
The custom ``httpx.HTTPTransport(socket_options=[SO_KEEPALIVE, ...])``
in ``_build_keepalive_http_client()`` was introduced to fix CLOSE-WAIT
socket accumulation on long-lived connections (#10324).
That approach broke streaming for providers behind reverse proxies
(OpenResty, Cloudflare, etc.) because the custom socket options
conflict with the proxy's chunked-transfer handling (#54049, #12952).
It also stripped TCP_NODELAY, stalling TLS handshakes and SSE encoding.
Narrow per-provider bypasses were added for Copilot (#50298), Codex
(#36623, #12953), but the root cause remained.
The fix moves connection lifecycle management from the socket layer to
the HTTP pool layer:
- ``httpx.Limits(keepalive_expiry=20.0)`` tells httpx to close idle
pooled connections at 20 s, before a reverse proxy's typical 30-60 s
timeout drops them and causes CLOSE-WAIT accumulation.
- The default httpx transport preserves OS TCP defaults (including
TCP_NODELAY), so TLS handshakes and SSE chunked encoding work
correctly.
- ``trust_env=False`` prevents httpx from double-dipping on env vars
(we handle proxy detection ourselves via ``_get_proxy_for_base_url``
which respects NO_PROXY).
- The Copilot host bypass (line 3632) is no longer needed since all
providers now use the same standard httpx.Client.
Closes#54049. Supersedes #12010, #36623, #12953, #50298.
Follow-up to #56236: the broadened root token /[/.]*\** treats any run of
dots after the root slash as a collapse spelling, so a literal root-level
directory named '...' (rm -rf /...) was unconditionally hardline-blocked
with no approval path. Tighten the token to /(?:(?:\.\.?)?/)*(?:\.\.?)?\**
so each inter-slash segment must be exactly '.' or '..' — all real collapse
spellings (//, /., /./, /.., //*, ///, /../..) stay on the hardline floor
while literal dot-run dirs fall through to the softer DANGEROUS_PATTERNS
rules like every other real path.
* feat(approvals): /deny <reason> relays denial reason to the agent
Port from qwibitai/nanoclaw#2832 (reject with reason).
Gateway /deny now accepts an optional trailing reason (/deny <reason>
or /deny all <reason>). The reason rides on the per-session approval
entry through resolve_gateway_approval -> _await_gateway_decision and is
appended to the BLOCKED tool result the agent receives, so a declined
agent can adapt instead of only hearing 'denied'.
Adapted to hermes-agent's synchronous single-command /deny model: no DB
state, no second-message capture step, no migration. Reason is capped at
280 chars and threaded through both the terminal-command guard and the
execute_code guard. Plain /deny and the approve paths are unchanged.
- tools/approval.py: _ApprovalEntry.reason; resolve_gateway_approval gains
optional reason; _await_gateway_decision returns it; both gateway BLOCKED
messages include it
- gateway/slash_commands.py: parse leading 'all' + trailing reason
- locales/en.yaml: deny.denied_reason_{singular,plural}
- hermes_cli/commands.py: /deny args_hint '[all] [reason]'
- tests: 3 new (with-reason, all+reason, plain-deny regression)
* fix(ci): localize deny-reason keys across all locales + update interrupt-path assertions
CI surfaced two enforced invariants broken by the deny-with-reason change:
- test_i18n catalog-parity requires every locale to carry the same keys as
en.yaml with matching placeholders. Added deny.denied_reason_singular/plural
(with {count}/{reason}) to all 15 non-English locales.
- test_approval_interrupt asserts the exact dict from _await_gateway_decision,
which now carries a 'reason' key (None on the interrupt/timeout paths).
Inspired by Claude Code v2.1.199 (July 2, 2026): stacked slash-skill
invocations load all leading skills (up to 5), not just the first.
- agent/skill_commands.py: split_stacked_skill_commands() consumes leading
/skill tokens (stops at the first non-skill token so slash-path arguments
are never swallowed); build_stacked_skill_invocation_message() composes
the multi-skill turn reusing the existing bundle scaffolding markers so
extract_user_instruction_from_skill_message() keeps memory providers
storing the user's instruction, not N skill bodies.
- cli.py + gateway/run.py: dispatch the stacked path on both surfaces.
- 11 new tests + docs section in skills.md.
Port from anomalyco/opencode#34529: MCP servers can emit
notifications/message logging notifications (RFC 5424 levels), but the
MCP SDK's default logging_callback silently discards them — server-side
warnings/errors during tool calls were invisible.
- tools/mcp_tool.py: pass a logging_callback to every ClientSession
(stdio, SSE, streamable HTTP old+new API paths via the shared
sampling_kwargs sites), mapping the 8 MCP log levels onto Python
logging levels and tagging entries with [server/logger] origin.
- JSON-serialize non-string payloads, cap at 2000 chars so a chatty
server can't flood agent.log, never raise from the handler.
- Gated on SDK support (_check_logging_callback_support) mirroring the
existing message_handler gate for old SDK versions.
- tests/tools/test_mcp_server_log_notifications.py: 10 tests covering
level mapping, origin tagging, JSON payloads, truncation, and the
never-raise contract.
Inspired by Claude Code v2.1.199 (July 2, 2026): SSL certificate errors
(TLS-inspecting proxies, missing CA bundles, expired certs) no longer
burn retries before showing actionable guidance — they fail immediately
with the fix hint.
- agent/error_classifier.py: new FailoverReason.ssl_cert_verification +
_SSL_CERT_VERIFY_PATTERNS, checked BEFORE the transient-SSL patterns
(cert-verify messages also contain '[SSL:' and previously retried
forever as timeout). Non-retryable, no compression, no fallback churn.
- agent/conversation_loop.py: dedicated status line + per-cause fix
hints (corporate proxy CA bundle, certifi refresh, self-signed local
endpoints) on the non-retryable abort path.
- 7 new tests incl. regression guards (transient alerts still retry,
large-session cert failure doesn't trigger compression).
UV's bundled Python ships a minimal PATH that excludes /bin and /usr/bin,
