* feat(compaction): always rebuild the system prompt at the commit boundary — keep-prompt now gated on byte equality of the LIVE builder output; plugin sections re-render with fail-open to last good bytes
* feat(clock): 'Conversation started' resolves through the session-lineage ROOT — a compacted/rotated session keeps its original birth date (Bot Mode forever-chats know when they were first born)
* test: retire old-contract pins — plugin sections re-render at invalidate (freeze stays restore-only), commit boundary always runs the live builder, byte-equal keep preserves object identity
* test(system_prompt): cover session-start anchoring + fix Windows-portable expectation
- Add TestSessionStartLike unit tests for _session_start_like(): session-id
embedded timestamp, session_start fallback, now fallback, non-matching id.
- Add a build-level regression: a session started Jan 1 must still render
'Conversation started: Thursday, January 01' when the prompt is rebuilt
on Jan 2 (the rebuild-drift bug).
- test_coding_prompt_preserves_legacy_workspace_order hardcoded '/hermes'
while production renders str(Path('/hermes')) — backslash on Windows made
the suite fail on Windows (CI runs Linux, so it was never caught). Build
the expectation via str(Path()) to match production on every platform.
* fix(system_prompt): anchor 'Conversation started' to the real session start
The timestamp line stamped hermes_time.now() at system-prompt build time.
The prompt is rebuilt on compression, fresh-agent gateway turns, and
resume-without-stored-prompt, so the date silently advanced to whatever
day the prompt was last rebuilt — a chat that started on Wednesday read
as 'Conversation started: Thursday' after a Thursday-morning resume,
contradicting the fresh per-turn time hint.
Resolve the true start via _session_start_like(): the timestamp embedded
in the session id (YYYYMMDD_HHMMSS_..., immutable for the session life)
-> agent.session_start -> now() only as last resort. Box-local stamps are
attached to the box's local zone then converted to the rendered zone so
the date is consistent with the per-turn clock. The line stays date-only
and is now byte-stable for the whole session (never moves on rebuild),
preserving prefix-cache KV. The zone suffix and _bot_chat_timeless_prompt
behaviour are untouched.

* refactor(prompt): remove the Nous Subscription block from the system prompt (~1.2K tokens/call)
* chore: retrigger CI (zero-job dispatch failure, auto-heal)
The external memory provider's `system_prompt_block()` was injected
unconditionally into the system prompt, while the provider's tools were
gated by `memory_provider_tools_enabled()` via platform_toolsets or
disabled_toolsets. Result: the agent received instructions to call
`mnemosyne_remember`, `mnemosyne_recall`, etc., that did not exist in
its tool surface.
Centralize the gating into `memory_provider_tools_exposed(agent)`, use
it from both `inject_memory_provider_tools` and the system prompt
assembly path, and add regression tests covering:
* memory toolset enabled -> both tools and prompt block exposed,
* memory in disabled_toolsets -> neither exposed,
* memory not in enabled_toolsets and not built-in -> neither exposed,
* the built-in "memory" tool present as an opt-in -> both exposed,
* parity between `inject_memory_provider_tools` and
`memory_provider_tools_exposed`.
Audit finding (Blank Slate): the system prompt advertised web_search,
skill_view, todo, and the hermes-agent skill even when the toolset had
none of them — the model chases phantoms it can't call.
- hermes-agent skill is now essential: cannot be disabled (config reads
strip it, hermes tools writes drop it), cannot be deleted by
skill_manage, is re-seeded past curator suppression, and is seeded
even on .no-bundled-skills profiles (Blank Slate / --no-skills).
- Blank Slate core toolsets grow from file+terminal to
file+terminal+vision+skills: read_file cannot read images and points
at vision_analyze; the essential skill needs skill_view to load.
- HERMES_AGENT_HELP_GUIDANCE degrades to a docs-URL-only variant when
skill tools are absent.
- Execution-discipline guidance drops its web_search lines when web
tools are off (execution_guidance_text renderer).
- Skills-index preamble says 'basic tools like terminal' instead of
naming web_search when web tools are off.
- Coding operating brief drops the todo-tracking sentence when the todo
tool isn't loaded.
All gating keys off agent.valid_tool_names, fixed at session
construction — prompt stays byte-stable per session (cache-safe).
Running `pytest tests/agent/test_prompt_builder.py
tests/agent/test_system_prompt.py` failed
test_build_system_prompt_records_stable_prefix with AttributeError:
'...SimpleNamespace' object has no attribute '_emit_status'
(#93018). A truncation warning recorded by test_prompt_builder.py stays
in the shared thread context under plain pytest, so the later file's
build_system_prompt call drains a warning and forwards it to
agent._emit_status - which the test stub lacked.
Harden both sides:
- tests/agent/test_system_prompt.py: _make_agent() stub gains a no-op
_emit_status, so draining a stray warning is harmless.
- tests/agent/test_prompt_builder.py: autouse fixture drains pending
truncation warnings after every test, leaving the ContextVar clean.
The order-dependent failure no longer reproduces in either ordering.
Un-fences OPENAI_MODEL_EXECUTION_GUIDANCE from the gpt/codex/grok substring
check and gives it its own injection gate, independent of
tool_use_enforcement, controlled by config.yaml `agent.execution_guidance`
(auto/true/false/list — same semantics as tool_use_enforcement). The "auto"
list (EXECUTION_GUIDANCE_MODELS) now also covers deepseek, kimi, qwen, glm,
minimax, mimo, and mistral.
Composio agentic-eval traces showed Hermes+DeepSeek/Kimi failing where
competitors passed: financial math done in prose, no read-back after
external writes, malformed identifiers "repaired", completeness claimed
despite count mismatches. The discipline block existed but those models
never received it.
The block is extended with compact clauses distilled from that analysis:
- external-write read-back (tool-call success is not task success; internal
file edits already confirmed by the tool are not re-verified)
- count reconciliation (declared totals/has_more are hard assertions)
- literal preservation (never normalize identifiers that fail a stated
format; lookup success does not validate a malformed token)
- retry-differently (empty/partial/suspiciously narrow results get a
broader retry before concluding)
- completion gated on verification (done = every named acceptance
criterion verified, never a plausible subset)
The todo tool description now encourages enumeration-as-checklist for
"all N items" tasks and gates completed status on verified work, never
intent.
Guidance is chosen once at session start keyed on model name, so the
system prompt stays byte-stable for the life of a conversation.

load_soul_md resolved the home ambiently, so a build thread that lost the
HERMES_HOME ContextVar read the launch profile's SOUL.md into another
profile's prompt — same class as the skills-index leak fixed in #86313.
load_soul_md and build_context_files_prompt now accept home_override, and
build_system_prompt_parts passes the agent's own home (from session_db)
at both SOUL call sites. Ambient behavior unchanged when no override.
Review feedback: the previous tests mocked get_hermes_home,
get_default_hermes_root and _resolve_active_profile_name, so they
checked template rendering but never exercised the relationship that
causes the defect — _resolve_active_profile_name returns a named profile
only when the active home is already <root>/profiles/<name>, which is
precisely why appending that suffix doubled it.
Replace them with tests that set a real HERMES_HOME under a tmp root and
mock no resolver. They assert the chain first
(_resolve_active_profile_name == "coder", get_hermes_home == the profile
dir, get_default_hermes_root == the root), then the rendered prompt.
Adds the default-profile branch the same way.
This also removes the order-dependent failures noted in the PR
description. Module-attribute monkeypatching stops taking effect once
other files in tests/agent/ have run, which is what made the mocked
tests fail in a full-directory run; the un-mocked tests are immune.
tests/agent/ now reports 87 failures — identical to the baseline on
unmodified main, with none in this file.

The named-profile branch of the "Active Hermes profile" hint built its
paths by appending `/profiles/{active_profile}` to `get_hermes_home()`.
But `_resolve_active_profile_name()` returns a non-default name *only*
when `get_hermes_home()` has already resolved under `<root>/profiles/`
— that is how it derives the name in the first place. Both scoping
mechanisms (a `HERMES_HOME=<root>/profiles/<name>` env var and the
multiplexer's `set_hermes_home_override` contextvar) satisfy that, so
the suffix always doubled.
The same branch used `get_hermes_home()` for the *default* profile's
data pointers, where the root was intended — placing them inside the
active profile.
On a real 4-profile install the hint rendered:
reads and writes ~/.hermes/profiles/via/profiles/via/
default profile's data lives at ~/.hermes/profiles/via/skills/
against actual paths of `~/.hermes/profiles/via/` and `~/.hermes/skills/`.
Use the session home directly as the profile home, and
`get_default_hermes_root()` for the root pointers. Every named-profile
session was shipping a prompt that named nonexistent directories and
mislabeled this profile's own skills/plugins/cron/memories as the
default profile's — the exact cross-profile confusion the hint and
`classify_cross_profile_target` exist to prevent.
The default-profile branch is unchanged.

Guard both extra lookups with isinstance(dict) before merging, so a
truthy non-mapping `extra` value (e.g. `extra: "true"`) degrades to the
base Telegram hint instead of raising TypeError and aborting
system-prompt construction. Keep the narrowed except ImportError.
Add an integration test exercising the real config path (HERMES_HOME +
gateway.platforms.telegram.extra.rich_messages) and a regression test
for the malformed-extra fail-open path. The integration test fails on
main and passes with the fix.
Commit b45a217e0 gated the TELEGRAM_RICH_MESSAGES_HINT extension behind
a config read at the top-level ``platforms.telegram.extra.rich_messages``
key, but the Telegram adapter reads the same setting from the canonical
``gateway.platforms.telegram.extra.rich_messages`` path. When users set
the setting in the canonical location (the only one documented), the
lookup returned None and the extension never fired — the model degraded
pipe tables to bullet lists, task lists to plain dashes, and never
produced <details> blocks or block math.
Fix: merge both ``gateway.platforms.telegram.extra`` and the top-level
``platforms.telegram.extra`` with the same precedence the adapter uses
(top-level leaf wins), so config-wizard writes and dashboard-setup keys
are visible alongside the canonical gateway location. Narrow the
except-guard to ImportError so real config-stack failures surface.
The skills index is runtime-mutable: the agent adds and patches skills mid-session, so it is not byte-stable. Keeping it in the stable band breaks that band prefix-cache contract, because every skill edit changes the stable band and invalidates the entire cached prefix in front of it. Move it to the front of the volatile band so the stable scaffold (identity, tool guidance, model guidance) stays cacheable across skill edits.
Follow-up on the salvaged #64611 commit: the original guard blocked the
install tree unconditionally, which would have broken the legitimate
'developing Hermes from a source clone' CLI flow (launching hermes inside
the repo and getting its AGENTS.md as project context).
Refined policy:
- resolve_context_cwd(): validates configured paths (missing dir -> None +
warning) but honors an EXPLICIT install-tree cwd verbatim — deliberate
user choice.
- build_context_files_prompt(): blocks only the cwd=None -> os.getcwd()
FALLBACK into the install tree, with a new allow_install_tree_fallback
param. system_prompt.py passes it for platform cli/tui (launch dir is
the user's real shell cwd there); desktop/gateway surfaces keep the
guard (their fallback dir is self-spawned, never user-picked).
- Warning log names the resolved dir and the terminal.cwd remedy.
E2E-verified all five scenarios: desktop fallback blocked, in-tree CLI dev
keeps AGENTS.md, explicit install-tree cwd honored, invalid TERMINAL_CWD
falls to None then blocked, normal workspace loads.
The platform hint in PLATFORM_HINTS['telegram'] always encouraged rich
Markdown constructs (tables, task lists, math, collapsible details) even
when rich_messages: false (the default). This caused the agent to produce
formatting that MarkdownV2 cannot render, especially broken on Telegram Web.
Split the hint into a base hint (MarkdownV2-compatible) and a
TELEGRAM_RICH_MESSAGES_HINT extension. The extension is conditionally
appended in system_prompt.py only when
platforms.telegram.extra.rich_messages is true.
Fixes#57122
Context files (AGENTS.md, CLAUDE.md, .hermes.md, .cursorrules, SOUL.md) were
hard-capped at a flat 20K chars before head/tail truncation. Among the agent
harnesses we track, only Codex caps project docs at all (32 KiB); Claude Code,
OpenCode, and Cline load them whole. The flat 20K predates large context
windows and silently truncates real-world AGENTS.md files.
B — dynamic cap: when context_file_max_chars is unset (now the shipped
default), the cap scales with the model's context window
(ctx_tokens * 4 * 0.06, floor 20K, ceiling 500K). Small-context models stay at
the historical 20K; a 200K model gets 48K; large models stop truncating real
docs. An explicit context_file_max_chars still wins. Context length is resolved
once per conversation (stable -> prompt cache untouched).
C — when truncation does happen, the marker now names the concrete file path
and tells the agent to read_file it for the full content.
Validation: 154 targeted tests + full agent/ + hermes_cli/ + test_config
(0 failures); E2E against a real 60K AGENTS.md confirms small windows truncate
with the path-bearing marker, large windows load whole, and the system prompt
is byte-stable across rebuilds.
* feat(agent): coding-context posture with per-model edit-format tuning
Hermes detects when it's running in a coding context — an interactive
surface (CLI, TUI, ACP, desktop) sitting in a code workspace (git repo or
recognised project root) — and shifts into a coding posture. Outside that
(chat platforms, non-workspaces) nothing changes.
The posture is modelled as a frozen RuntimeMode selected from a small
ContextProfile registry (coding/general). A profile is data: the toolset to
collapse to, the operating brief to inject, and seams for model routing and
memory. Every domain reads the same resolved object instead of re-probing
git/config on its own:
- System prompt — RuntimeMode.system_blocks(): an operating brief (gather
context before editing, edit through tools not chat, verify with terminal,
cap retry loops) plus a live git/workspace snapshot, built once and baked
into the stable prompt tier so per-conversation caching is preserved.
- Per-model edit-format tuning — the brief nudges each model family toward
the patch mode it handles best: OpenAI/Codex toward mode='patch' (V4A
multi-file diffs), Anthropic toward mode='replace' (string replacement).
The model id rides on RuntimeMode; unknown families keep neutral wording.
- Skill index — non-coding skill categories are pruned from the prompt's
skill index (discovery-only; skills_list/skill_view still reach the full
catalog, with a disclosure note).
- Toolset — only under the opt-in 'focus' mode does the posture collapse to
the coding toolset + enabled MCP servers; the default posture is
prompt-only and never overrides configured toolsets.
Activation via agent.coding_context: auto (default), focus, on, off.
Subagents inherit the posture for free via toolset inheritance + the shared
prompt builder. Detection is not memoized so a long-lived gateway/TUI
process can't pin a stale posture across working directories.
* feat(agent): cover new-file authoring in the coding edit-format nudge
The per-model edit-format guidance only addressed editing existing code
(patch mode='patch' vs 'replace'), but authoring a brand-new file —
write_file, not patch — is a large fraction of real coding work and the
nudge was silent on it. Surfaced when building a single-file artifact where
the dominant operation was write_file and the steering offered no guidance.
Both family lines now lead with "author new files with write_file; for
edits to existing code prefer ...". Tests assert write_file appears in each
family's brief; unknown families still get neutral wording.
* docs(agent): correct memoization docstring + clarify TUI config-load asymmetry
* feat(agent): sharpen the coding posture — verify-loop facts, wider edit steering, $HOME guard
Tuning pass on the coding posture from dogfooding it as a harness:
- Workspace snapshot now hands the model its verify loop up front:
detected manifests + package manager (lockfile sniff), the exact
verify commands (package.json scripts, Makefile targets,
scripts/run_tests.sh, pytest config), and which context files
(AGENTS.md / CLAUDE.md / .cursorrules) exist at the root. Marker-only
(non-git) projects get the snapshot too instead of nothing. The
"verify before claiming done" brief line was the highest-value piece
in evals — this turns it from advice into an executable loop instead
of making the model rediscover the test command every session. Still
stat-cheap, size-guarded reads, built once at prompt time.
- Edit-format steering covers the families Hermes actually serves:
Gemini and open-weight coding models (DeepSeek, Qwen, Kimi, GLM,
Grok, Hermes, Llama, Mistral, Devstral, MiniMax) steer to
mode='replace' — their RL scaffolds use str_replace-style editors.
Previously only GPT/Codex and Claude families got steering; the
models Hermes users disproportionately run all fell to neutral.
- Operating brief gains four behaviors elite harnesses encode: batch
independent reads/searches in one turn; fix root causes and the bug
class (sibling call paths), not the reported site; no drive-by
refactors/renames/reformatting; never read, print, or commit secrets.
Plus a patch-failure escalation ladder: after the same region fails
twice, rewrite the enclosing function/file with write_file instead of
a third patch attempt.
- $HOME dotfiles guard: a git repo rooted exactly at the home directory
(or a marker sitting in it, e.g. a global ~/AGENTS.md) is user config,
not a code workspace — without the guard, every session anywhere under
a dotfiles-managed home silently flipped to the coding posture. Real
projects under such a home still detect via their own markers/repos;
'on' mode bypasses the guard.
