- Fixes#3323 Slice 2.1 - Phase 1a (read tool selector parsing)
Five defects found by auditing the agent stack, all of which let the harness act
confidently on a wrong picture of its own state.
1. A turn that errored discarded the record of tools that had already run. The CLI
hands run_turn a CLONE of the session; the turn appends the user message, each
assistant reply, and a tool_result per executed tool to that clone alone. The error
path dropped it while the side effects of those tools remained on disk, and the
recovery path then replayed the same user input against a session showing no sign
they had ever run — inviting a second execution of tools that are not idempotent.
The clone is now adopted before teardown, and recovery resumes the turn instead of
replaying it (new ConversationRuntime::resume_turn).
2. Every sizing guard was computed against the model NAME's context window. With a
local server behind a cloud model alias that is 200k against a much smaller
backend, which does not make the preflights inaccurate — it makes them unreachable.
CLAW_CONTEXT_WINDOW now declares the real window; model_token_limit honours it and
returns a limit for unrecognised models instead of None, max_tokens is capped to a
quarter of it, and the auto-compaction threshold derives from it (70%) rather than
defaulting to a 200k-window constant.
3. Whether to recover by discarding conversation history was decided by substring
matching on rendered error prose, including strings that ordinary transport and
decode failures also produce — so a dropped connection cost the session its
transcript. Classification now happens in the API layer, where the error still has
its type and the request is still in hand: typed overflow errors, plus ambiguous
transport failures only when the request actually filled the window. The two
copy-pasted detection blocks are gone.
4. The top-level agent loop had no iteration ceiling (usize::MAX) while spawned
subagents were bounded at 32. It now gets the same bound, overridable with
CLAW_MAX_TURN_ITERATIONS.
5. Auto-continue nudges were injected as USER turns, so harness-authored text was
persisted, re-sent on every later request, and folded into compaction summaries as
something the user had said. They are recorded as system turns now; the wire
payload is unchanged.
Also replaces the repository's own self-host section, which described a translator
and a serving stack no longer in the request path. That file is folded into the
system prompt verbatim, so it was briefing the model with an architecture that does
not exist.
(cherry picked from commit c8834cb4d1a3372eb70241429f641162a420297e)
A reply carrying no tool_use ended the turn unconditionally. Small local
models routinely narrate the next tool call in prose — "Now running the
EEC-V probe:" — and then emit EOS, so the announced work never happened
and the user was dropped back at the prompt. The same failure wears a
second hat mid-task: stopping to ask for a go-ahead on work already
requested.
The loop now inspects the final line of a tool-less reply. If it
announces a pending action, or asks a question after tools have already
run this turn, a short nudge is pushed as a user message and the loop
continues instead of breaking. The budget is bounded (default 3 per
turn, CLAW_MAX_STALL_NUDGES, 0 disables) so a model that really is
finished still gets to stop.
Prevention pairs with recovery: the "Doing tasks" system-prompt section
now tells the model to act in the turn it plans in.
Tests cover the auto-continue, the bound, a plain completion that must
NOT be nudged, the disable switch, and last-line-only detection. The
behavioural pair was mutation-checked: reverting the continue to a break
fails both.
(cherry picked from commit 9035fe6f4bf4a8d4cb70d7a3baf1f3748c757498)
The git diff snapshot is rendered into the *system prompt*, so its cost is
paid again by every session whose working tree has changed -- and a diff
changes on essentially every edit. The 50_000-char budget was four times the
entire instruction-file budget (12_000) and unbounded in practical effect: a
single modified file added ~15_000 tokens to the prompt.
Measured against a self-hosted backend, one uncommitted change took the
prompt from 8_302 to 23_457 tokens and a one-word reply from ~3 s to 296 s.
With the new default the same session is 7_911 tokens and 36 s. That cost is
absorbable against a hosted frontier model and ruinous against a local one.
Default is now 4_000 chars, matching MAX_INSTRUCTION_FILE_CHARS, and is
overridable with CLAW_MAX_GIT_DIFF_CHARS following the same pattern as
CLAW_MAX_READ_CHARS. A budget of 0 omits the snapshot entirely rather than
emitting an empty section with a truncation marker; git status and the
recent-commit list are unaffected either way.

Two related gaps let a single agentic turn exceed a small context window,
with no recovery path once it happened.
1. read_file's character ceiling was a hardcoded 64 KB (~16k tokens), sized
for a 200k window. Two reads in one turn reach ~48k tokens, which a 32k
backend rejects outright. Make it configurable via CLAW_MAX_READ_CHARS,
defaulting to the existing 64 KB so behavior is unchanged unless set.
Reads remain paged, not refused: callers still get truncated/nextOffset.
2. Compaction could not help, because it works at message granularity and an
agentic turn is five messages (user / assistant+tool_use / tool_result /
assistant+tool_use / tool_result). With preserve_recent_messages: 4 the
only droppable message is the short user prompt, so the two oversized
tool results were preserved verbatim by design.
Trim preserved tool-result payloads over 16 KB to a head/tail excerpt with
an explicit "[... N characters elided ...]" marker, so the model knows its
view is partial and can re-read. Small payloads pass through untouched.
Also apply trimming on the early-return path: a session can exceed the
window while holding fewer messages than preserve_recent_messages, where
should_compact is false and message-granular compaction has no move to
make. compact_now no longer gates on removed_message_count alone, which
would have computed the smaller session and then discarded it.
Also fixes a pre-existing flaky test: repl_executes_python_code resolves the
python runtime through PATH, which the PowerShell tests blank while they run.
It now takes the same env_lock, so it no longer intermittently fails with
"python runtime not found" on a machine that has python.

(cherry picked from commit b0d4d41e8132f8dc75717b1f74554d649639de10)
The usage-based compaction gate is post-hoc: it can only see the context
after a call returns and reports its counters. Between that measurement and
the next request the session can grow enormously - a reasoning model emitting
a long thinking block, then a tool result carrying a large file.
Observed live: a call measured at 17,858 prompt tokens generated 10,842 more,
a read_file added ~19k on top, and the next request reached the provider at
47,755 tokens and was rejected outright. No tuning of the post-hoc threshold
prevents that, because nothing measures the session in between.
Add a pre-send check driven by estimate_session_tokens, a local heuristic over
the transcript, so it costs no API call and works before any usage has been
recorded at all.
Note the limit of this: compaction preserves the 4 most recent messages, and
in an agentic tool-use loop those messages ARE the tool results carrying the
bulk. This check bounds gradual growth; it cannot rescue a session whose last
four messages already exceed the window.

(cherry picked from commit 26ab52d70fb17e49b74d523aecfc1da7f69a6d60)
`maybe_auto_compact` gated on `usage_tracker.cumulative_usage().input_tokens`,
which is wrong in two independent ways:
1. It ignores cached input. With prompt caching a warm call reports
`input_tokens: 2` and puts the real context in `cache_read_input_tokens`,
so the counter barely moved and auto-compaction never fired at all,
however large the conversation grew. Backends without prompt caching
report the whole prompt as `input_tokens`, so the bug was invisible there.
2. A sum across calls is not a context measurement, and it never decreases.
Once it did cross the threshold, every subsequent iteration compacted
again, permanently, even after compaction had shrunk the context.
Gate on the latest call's total input instead — input + cache_creation +
cache_read — which is the live context window size. It rises with the real
context and falls back below the threshold once compaction has done its job,
so no counter reset is needed.
`CLAUDE_CODE_AUTO_COMPACT_INPUT_TOKENS` now means what it reads like:
compact when the live context reaches N tokens. The default of 100_000 is
unchanged and still lands at 50% of a 200k window.
Adds `TokenUsage::total_input_tokens()` (saturating) and four tests: the
cached-usage shape that never fired, non-latching across three turns, and
two unit tests for the new helper.

(cherry picked from commit aebba4e77eddf585fc5b21123967dbc4ebb6e6a1)
An unbounded read_file returned the entire file, which on a small-context
backend overflows the model's window. The backend then rejects the whole
request (llama-server: "request (N tokens) exceeds the available context
size"), which kills the turn — so reading everything at once is precisely
what makes the session stop. Observed live: one 100 KB source file is
~25k tokens against a 32k window with a ~6k-token prefix, and a session
read the same file three times and died on six 400s.
read_file now returns a page and says so:
- absent `limit` yields DEFAULT_READ_LINES (2000) rather than EOF
- MAX_READ_CHARS (64 KB) bounds the payload even when `limit` is
explicit, so minified or generated files can't defeat the line cap
- `truncated` and `nextOffset` tell the caller it has a partial view
and exactly where to resume; the tool description explains both
MAX_READ_SIZE (10 MB) is untouched: it is a process guard against slurping
huge or binary blobs, not a context guard, and at ~2.5M tokens it never
fires on the files that actually overflow a window.
Also clears pre-existing clippy failures in trident.rs that blocked
-D warnings on every edit to this crate.

feat: add persistent auto-memory system
Implement a file-based persistent memory system that allows the AI to retain knowledge about users, feedback, projects, and references across sessions.
## Implementation Details
- MemoryStore data layer with FNV-1a workspace fingerprinting
- MemoryRead/MemoryWrite tools with security hardening (path traversal, symlink, absolute path, and size limit protections)
- System prompt injection of MEMORY.md index with prompt injection mitigation (fenced code block + trust-lowering notice)
- autoMemoryEnabled config option (defaults to true)
- Doctor health check for auto-memory state
- /memory command enhancement showing persistent memory info
## Verification
✓ 1023 lib tests pass
✓ Output format contract tests pass
✓ Release build succeeds
✓ Security hardening verified

* fix(runtime): prompt permission mode never invokes the prompter
PermissionMode derives Ord from declaration order, placing Prompt (and Allow)
above the real privilege ladder (ReadOnly < WorkspaceWrite < DangerFullAccess).
In PermissionPolicy::authorize_with_context the ladder check
'current_mode >= required_mode' therefore evaluates true for every tool when the
active mode is Prompt (3 >= {0,1,2}), returning Allow and making the subsequent
'if current_mode == PermissionMode::Prompt' branch that routes to prompt_or_deny
unreachable.
Effect: a session configured with the 'prompt' permission mode silently
auto-allows every tool and never calls the prompter (reached via
ConversationRuntime::run_turn with an interactive prompter), defeating the mode's
entire purpose. The sibling PermissionEnforcer already special-cases Prompt
before its own 'active_mode >= required_mode' check, confirming Prompt is not
meant to be part of the ordered ladder.
Fix: exclude Prompt from the ordered-ladder comparison so Prompt mode falls
through to the interactive prompt path. Allow remains handled by its explicit
equality check. The same comparison appears twice in authorize_with_context —
once in the shared tail and once inside the 'Some(PermissionOverride::Allow)'
arm, which is reached when a hook emits permissionDecision "allow" — so both
copies carry the guard; guarding only the tail still left a hook able to
auto-allow every tool in Prompt mode without ever consulting the prompter.
Adds regression tests covering Prompt mode with a prompter, without a prompter,
and with a hook allow override.
* refactor(runtime): make the permission privilege ladder an explicit rank
`PermissionMode` derived `PartialOrd`/`Ord`, so the ladder deciding whether a
tool runs without asking was declaration order. A variant inserted in the middle
of the enum re-ranked it silently, and the difference between "this tool may
run" and "this tool may run after a prompt" was a property of where an `enum`
line happened to sit. That is how `Prompt` came to outrank `DangerFullAccess`,
satisfy `current_mode >= required_mode` for every tool, and skip the prompter.
Replace the derive with `privilege_rank`, an exhaustive `match` naming every
variant, so inserting one is a build failure rather than a silent re-ranking.
`Ord` is deliberately not derived, so a stray `>=` on two modes no longer
compiles; the two comparisons outside this module now say which rank they read
(`PermissionEnforcer::check_with_required_mode` and the `claw doctor` permission
check). Both keep their previous answers, since `privilege_rank` reproduces the
old declaration order exactly, including `Prompt` and `Allow` above the tiers.
`Prompt` and `Allow` are modes of operation, not privilege tiers, so they are
never ranked *against* a tool requirement. The new `covers` predicate states
that by name rather than by number: `Allow` always covers, `Prompt` never does
(it asks), and only the three tiers compare ranks.
That also collapses the duplicated ladder in `authorize_with_context`. The
`Some(PermissionOverride::Allow)` arm carried a second, identical copy of the
ask-rule check and the ladder; it now falls through to the single copy below,
so a hook `allow` is an override rather than a bypass and the two copies can no
longer drift apart.
Behaviour is unchanged for every (mode, requirement, rule, override)
combination. The tests pin the `Prompt` routes — plain and hook-`allow` — across
all three tiers, plus the rank ordering itself.
validate_workspace_boundary compared paths lexically, so a location inside
the workspace spelled with different letter case (a working directory typed
as c:\users\... for C:\Users\...) or through the \\.\ device namespace was
reported as escaping the workspace.
When the lexical comparison fails, compare the path's canonical form before
reporting an escape. A path whose canonical form is outside the workspace
stays rejected.
accepts_equivalent_extended_path_at_workspace_boundary builds its paths
with backslash separators. Backslashes only separate path components on
Windows, so on Linux each path is a single component, the boundary check
rejects the path, and cargo test fails.
Run the test only on Windows, and call validate_workspace_boundary through
super:: so non-Windows test builds do not warn about an unused import.
Root knowledge base plus complexity-scored subdirectory files for the
rust/ workspace, its five highest-mass crates (runtime, rusty-claude-cli,
api, tools, commands, plugins), and the src/ Python porting workspace.
Generated via init-deep: 13 parallel explore agents, LSP/ast-grep code
map, centrality-scored placement. Snapshot in .omo/init-deep.json (local).
Keep extended-length and regular Windows paths comparable when enforcing workspace boundaries, including first-run roots that cannot yet be canonicalized. Add regression coverage for DOS and UNC path forms.

The startup probe validated only the mapping flags against the trivial
program `true`, but the real launcher always adds
--mount --ipc --pid --uts --fork. On environments where the user
namespace is created but mount propagation inside it is restricted
(e.g. AppArmor-restricted CI runners), the fallback mapping passed the
probe and the sandbox activated, yet every sandboxed command died with
"cannot change root filesystem propagation: Permission denied",
silently returning empty tool output and breaking the mock parity
suite.
The candidates now define the complete static launcher shape (mapping
flags + namespace flags), so probe success implies launch success; the
launcher reuses the candidate instead of re-appending the namespace
flags, keeping probe and launch as one source of truth. The
order-guarding test asserts the namespace flags are present in every
candidate.

The fallback candidate relies on the setuid newuidmap/newgidmap helpers
(uidmap package) plus a subuid/subgid range for the current user. Note in
the candidate docs that the startup probe rejects the candidate when those
are missing, so the plain --map-root-user form is used instead.
Plain `unshare --user --map-root-user` fails on kernels and containers
that block unprivileged writes to /proc/self/uid_map (e.g. GitHub Actions,
restricted AppArmor profiles). On those systems util-linux delegates to the
setuid newuidmap/newgidmap helpers when --map-auto is also present.
Add the combined form as a fallback candidate and build the launcher args
from the probed mapping, so systems without newuidmap/newgidmap or a
/etc/subuid range keep using the plain form.
No behavior change. Move the inline probe out of
unshare_user_namespace_works into a reusable unshare_probe helper and a
cached working_unshare_mapping() that picks the first working candidate
from UNSHARE_MAPPING_CANDIDATES, so the launcher and the capability probe
share one code path.
- Update slash_command_specs().len() assertion from 139 to 140.
The /setup command added by this PR increased the spec count by 1
but the test's expected count was not updated, causing CI failure.
- Add assert!(help.contains("/setup")) to the
renders_help_from_shared_specs test so the new command is
verified in the help output.
Fixes CI Build ❌ and Test ❌ on #3218.
The setup wizard was merged in PR #3017 but was orphaned -- it was not
declared as a module in main.rs, making it unreachable. Additionally,
the setup_wizard.rs imports RuntimeProviderConfig which did not exist
on upstream/main. This commit makes the wizard accessible and adds the
necessary RuntimeProviderConfig type.
Changes:
- Add RuntimeProviderConfig struct to runtime/src/config.rs with
kind(), api_key(), base_url(), model() accessors.
- Add parse_optional_provider_config() to parse the provider object
from merged settings JSON.
- Add provider() method to RuntimeConfig and RuntimeFeatureConfig.
- Export RuntimeProviderConfig, save_user_provider_settings,
clear_user_provider_settings, and default_config_home from runtime
crate public API (runtime/src/lib.rs).
- Add mod setup_wizard to rusty-claude-cli/src/main.rs.
- Add claw setup CLI subcommand.
- Add /setup slash command.
- Add Setup variant to SlashCommand enum.
- Add Setup to LocalHelpTopic enum.
- Add setup to diagnostic subcommand matching.
- Add subagentModel to TOP_LEVEL_FIELDS in config_validate.rs.

Hook config now supports the Claude Code structured hook format with
partial validation. Invalid hook entries are recorded in invalid_hooks
while valid siblings are retained, following the same pattern as MCP
partial validation (#440).
Key changes:
- RuntimeInvalidHookConfig now includes typed kind field (invalid_hooks_config
or unknown_hook_event) for machine-readable error classification
- Hook parsing collects all invalid entries instead of halting at first error
- Unknown hook event names recorded as invalid without rejecting valid hooks
- Legacy bare-string hooks still load with deprecation warnings
- Claude Code documented format loads without error (matcher + nested hooks)
- config/status/doctor JSON surfaces hook_validation metadata
- classify_error_kind maps hook errors to invalid_hooks_config

- Fix latest_session_alias_resolves_most_recent_managed_session test:
the test created sessions with 0 messages, which are now filtered out
by the message_count > 0 check in latest_session_excluding(). Updated
the test to call push_user_text() before saving so sessions have
at least one message and are findable by /resume latest.
- Add distinct error message when all sessions are empty (0 messages).
Previously, the same "no managed sessions found" message was returned
whether there were zero sessions or all sessions had 0 messages. Now:
- No sessions at all → "no managed sessions found in {path}. Start
claw to create a session..."
- Sessions exist but all empty → "all sessions are empty (0 messages)
in {path}. This usually means a fresh claw session is running but
no messages have been sent yet. Wait for a response in your other
session, then try --resume latest again."
- Add test for the all-sessions-empty error path.
