Weak local models reached for shell find/grep -r (unjailed, dumps
.gitignore'd trees, floods context) to answer 'does frontend/ exist?' /
'where is symbol X?'. Add two jailed, gitignore-aware read-only tools:
- GlobTool (name 'glob', T1, FILE_READ+DIRECTORY_LIST): find files by
glob pattern; survey-exempt from anti-hallucination read gates like
list_dir.
- GrepTool (name 'grep', T1, FILE_READ): regex content search, returns
path:line: text; skips gitignored, binary (NUL), and >2MB files.
Both reuse GitignoreMatcher + PathJail from the filesystem package,
share FileReadTool's jail/anchor/toggle, cap at 200 results. Registered
in ToolConfig.buildTools (fileRead block) and added to
StageConfig.ALWAYS_AVAILABLE_READ_TOOLS so every tool-granting stage can
call them. 6 tests green.
Vikunja #37.
The 'Not a directory' branch returned a bare message; models re-issued the
identical list_dir until cancel (session a60c54b0). Name the remedy: the path
is a FILE — file_read it or delete/convert it first. Regression test added.
Threads reasoning_content across inference calls and journal renders, filters
markdown noise out of L3 repo-knowledge retrieval, adds PlanLinter H3 checks,
and tightens filesystem tool output/dir-listing behavior surfaced by prior
live QA (see project_readloop_campaign memory).
Adds the failure-ticket + recovery-routing mechanism: a deterministic
gate->capability table gates whether a stage has agency to fix its own
failure, opens a FailureTicketOpenedEvent when it doesn't, and routes to
a metadata role=recovery stage (per-stage budget, cap 2, not reset by
TransitionExecuted) instead of retrying in place. Extends salvage
decisions with a RECOVER option so the review-gate judge can also route
to recovery, unifies deterministic-gate and review-gate routing through
routeToRecovery(), and has ExecutionPlanCompiler synthesize a
write-capable recovery stage + edge for freestyle plans. Read-only tools
(file_read, list_dir) are now always available on any tool-granting
stage so a recovery stage can inspect the write-less stage's failure
without flooding context via shell ls -R.
On a real (large) codebase, a file_read of a big file dumped the whole
body into L2 uncapped, evicting the files the stage actually needed —
the ContextTruncated we saw on real-repo runs. Bound it:
- readFile: auto-truncate a read-to-EOF past MAX_READ_LINES (400) with a
note pointing at start_line/end_line; hard char backstop (20k) for
very long lines. An explicit end_line is deliberate paging, honoured
in full. No contentHash baseline on a truncated view, so the
stale-write gate forces a real read before an edit.
- listDir (single-level): cap at LIST_MAX_ENTRIES (400) with a note.
(ListDirTool's recursive walk was already capped.)
Greenfield discovery/analyst stages thrashed on plane-2 REFERENCE_EXISTS
rejections: the model listed a not-yet-created dir (e.g. frontend/), got
hard-BLOCKED every round, and burned MAX_TOOL_ROUNDS without progress.
- New ToolCapability.DIRECTORY_LIST; ListDirTool declares it alongside
FILE_READ. ReferenceExistsRule now exempts directory enumeration (a
listing of an absent dir truthfully reports empty; only hallucinated
file *reads* still fail loud). Dispatch stays on capability, not name.
- Stage-agnostic rejection-loop breaker in the tool loop: after 3 rounds
where every tool call is rejected (BLOCKED/ERROR) with no success,
force the model to produce its output. Covers JSON-emitting stages the
read-loop breaker (file_written-only) never protected.
Bundles three operator-reliability guardrails (Vikunja #28/#29/#30) plus the
in-flight branch WIP they were built on top of (reasoning_content capture,
operator/project profile editor, write-jail workspaceRoot fix) — the tree is
interdependent (SessionOrchestrator references reasoningArtifactId from the WIP)
and does not compile as separable subsets, so it lands as one commit.
Guardrails:
- #28 mid-stage steering: ClientMessage.SteerSession -> GlobalStreamHandler ->
orchestrator.submitSteering, reusing SteeringNoteAddedEvent + existing context
fold (advisory, non-authoritative; invariants #3/#7). Closes the gap where
steering typed off an approval gate was silently dropped.
- #29 shell-in-file guardrail: ShellInFileContentRule (core:toolintent) blocks a
file_write whose content is a bare shell command (e.g. "mkdir -p ..."); FileWriteTool
description now advertises auto-mkdir of parent dirs. Basename-allowlist so the
extensionless case is caught; scripts/Makefiles/multiline exempt.
- #30 pt1 capability-gap detector: deterministic CapabilityGapDetector maps stage
intent -> implied ToolCapability, compares to granted tools, emits advisory
CapabilityGapDetectedEvent in FreestyleDriver.lockAndRun. Recorded, never fails
the gate and never auto-grants (invariants #3/#4/#5). Reflection rung is pt2.
Verified: ./gradlew check green (whole tree).
Writing to an existing directory path threw an IOException marked recoverable=false, which the orchestrator turns into a FATAL non-retryable stage failure — dead-ending the workflow on a correctable model mistake. Guard the directory case up front with a clear message and make write IO errors recoverable so the retry-with-feedback loop can self-correct.
Found while live-QAing freestyle_planning on a 12B local model:
- list_dir tool: recursive, .gitignore-aware listing so weak models stop
flooding context with `ls -R` over node_modules/build/dist. Wired into
the fileRead toggle + advertised to the planner (architect_freestyle).
- ContextClassifier: assistantToolCall turns are STRUCTURED, so the token
pruner never shreds the model's own tool-call history — that was causing
amnesia loops (re-issuing calls it had already made).
- Retire instruction-doc LLMLingua pruning (DOC_SOURCE_TYPES emptied): it
fused load-bearing procedural text into unparseable soup. The static
block stays small by dropping CLAUDE.md at the loader instead.
- AgentInstructionsLoader: load only AGENTS.md, not CLAUDE.md — the latter
targets the outer assistant and polluted the agent's stage context.
- DefaultSessionReducer: WorkflowFailed flips session status to FAILED (was
stuck ACTIVE forever, so clients/approval loops never saw a terminal).
- ShellTool: run shell command lines (cd/&&/pipes) via `sh -c`; unrunnable
program is recoverable instead of an uncaught IOException killing the
stage; malformed argv (non-string/collapsed-array) rejected with guidance.
- llmlingua sidecar: cap force_tokens to max_force_token (big docs blew the
assert and 500'd, so doc pruning silently failed open).
Tests added/updated across all of the above.
Enable autonomous QA through a remote OpenAI-compatible provider (NVIDIA NIM)
and harden the tool/approval path so unattended multi-stage runs complete.
- inference: add openai_compat provider (Bearer chat-completions for NIM/OpenAI),
dispatched by provider type "nim"/"openai"; key via api_key/api_key_env.
- server: bind configured [server] host/port instead of a hardcoded 8080;
POST /sessions accepts an optional `intent` (WS parity) for intent-driven workflows.
- kernel: thread the bound operator profile's approval_mode into per-tool gating so
auto/yolo enable unattended approval (engine still consulted; policy/plane-2 BLOCK
stays terminal); on a recoverable tool failure feed the tool's arg-schema back into
context so the model self-corrects instead of repeating a malformed call.
- tools: split deletion out of file_write into a separate, explicitly-named file_delete
tool — a model can no longer delete a file by getting a write-mode parameter wrong.
- server: add GET /metrics/tool-reliability — per-model tool-call validity from the
event log (measurement groundwork for capability-aware routing).
- docs: update AGENTS.md across kernel, tools, server, inference.

Block writing a file whose on-disk content changed since the session read it — a
concurrent/external edit the agent's view doesn't reflect. file_read records a
content hash on whole-file reads; the orchestrator's completion path now carries
the tool's structuredOutput (it previously dropped it, unlike SandboxedToolExecutor
— the two paths were inconsistent), so SessionContext.readHashes folds it.
StaleWriteRule compares the current hash (WorldProbe.contentHash) against the
read-time hash and BLOCKs a mismatch, telling the agent to re-read first. Files the
session wrote itself are excluded, so its own edits never look stale; partial reads
set no baseline.

When given a directory path, file_read now returns its entries (sorted,
sub-directories suffixed '/') instead of failing. The tool description
and path-param schema advertise this so the model discovers it rather
than giving up after a missing-file probe. Generalises file_read into a
'read this path' primitive; the existing PathJail/Plane-2 containment
already covers directories.
Live QA audit of role_pipeline against a sample repo surfaced and fixed a
chain of defects that prevented any tool+artifact workflow from running
end-to-end. The pipeline now completes cleanly with a real, validated,
reviewed file change.
- F-008 workflow: propagate stage token_budget -> generationConfig.maxTokens
(TomlWorkflowLoader) so large stages stop truncating at the 2048 default.
- F-009 tools/kernel: file_read missing-file is recoverable; recoverable tool
errors feed back into the loop instead of aborting the stage.
- F-010/F-018 kernel: reject premature stage_complete and nudge the model to
emit the owed artifact / invoke a write tool (bounded by MAX_TOOL_ROUNDS).
- F-011 schemas: list-typed artifact fields string -> array (analysis/design/
impl_plan) to match model output.
- F-012 kernel: strip an outer markdown code fence from LLM artifacts.
- F-013 validation: payload-validation failures are retryable; structural
failures stay terminal (wires the invariant-#7 reject+retry contract).
- F-014 tools: file_edit schema matches its real params; edits emit a diff.
- F-015 kernel: record tool-execution events + materialise a real file_written
artifact from the on-disk write; gate validation so a no-write stage cannot
be rubber-stamped (no more false-success runs).
- F-016 server: raise stageTimeoutMs 60s -> 180s for slow local models.
- F-019 artifacts/kernel: file_written artifact carries the unified diff so the
reviewer can verify the change (shared DiffUtil; file_write emits a diff too).
- F-020 tools: model-correctable file_edit failures are recoverable + steer
toward replace/file_write over the fragile patch op.
Full findings register (F-001..F-021, incl. open F-021 resume rehydrate bug)
in qa/audit-report-2026-06-08.md. All module tests green.
Two fixes surfaced by the 2026-06-08 QA audit running role_pipeline on a local
llama-server.
F-001: LlamaCppInferenceProvider sent both a GBNF grammar and tools on the same
request; llama.cpp rejects the combination ("Cannot use custom grammar
constraints with tools"), failing every stage that has tools and produces a
schema-constrained artifact. Drop the grammar when tools are present and rely on
post-hoc schema validation + retry (invariant #7 still holds). TODO left for a
first-class emit_artifact tool as the proper fix.
F-005: FileReadTool resolved relative paths via toAbsolutePath() against the JVM
process cwd instead of the bound workspace, so the file-read jail anchored to the
wrong root and disagreed with the Plane-2 PATH_CONTAINMENT check. Add workingDir
to FileReadConfig, wire workspace.workingDir in the per-workspace tool builder,
and give FileReadTool a resolvePath() mirroring FileWriteTool/FileEditTool.
Resolve a client-supplied workspace dir safely: canonicalize via toRealPath,
reject privileged locations, clamp to [tools] allowed_workspace_roots (permissive
when unset, logged), fall back to the boot default on any rejection. PathJail made
non-internal so the server can reuse its symlink-safe containment. (Axis 2 Phase A, task 4.)
Tools can declare how their output is compressed before it enters the
context pack, replacing uniform handling. Open-threads 6.3 / ADR-0003.
- core:tools/compression: ToolOutputCompressor interface,
IdentityCompressor default, declarative OutputCompressionSpec +
CompressionRule (StripBlankLines, StripLeadingWhitespace,
DropMatching, HeadTail), and the pure DeclarativeCompressor engine
(regexes compiled at construction; bypassOnError passes raw on
non-zero exit; never throws on input).
- Tool gains `outputCompressor` (default IdentityCompressor). FileReadTool
strips blanks + leading whitespace; ShellTool strips blanks + head/tail.
- SessionOrchestrator applies the resolved tool's compressor on the
ToolResult -> ContextEntry path only. Raw output stays authoritative
in the event log (invariant #6); compression is a pure function of
(raw, exitCode, spec), so no new event and replay stays deterministic.
- Spec is @Serializable/config-shaped (JSON round-trip tested). No
custom-tool-from-config path exists today, so first-party tools wire
in code; TOML-declared compression rides along when that path lands.
Tier B (format-aware parsers: failures-only test output, git-log oneline)
is a documented per-tool extension behind the interface, not built here.
Add ParamRole and a defaulted Tool.paramRoles to the tool contract; built-in
tools declare which params carry effects: file_read/write/edit -> path=PATH,
shell -> argv=EXEC_COMMAND. PathContainmentRule / ExecInterpreterRule /
NetworkHostRule now inspect only the declared params when roles are present, and
fall back to the looksLikePath / leading-token / extractHost heuristic only for
un-enriched (e.g. custom) tools - so a custom FILE_WRITE tool is still
containment-checked. Shared extractParamStrings flattens String and List<*>
(argv) values. SessionOrchestrator.runPlane2Assessment resolves the tool once
and passes tool.paramRoles into the assessment input.
This retires the arg-guessing from the first-party path: a slashy edit 'content'
arg is no longer mis-flagged as a path.
- fixed the tool overlay in tui.
- fixed tool calling - added schemas.
- getting all sessionIds via event store.
- instead of sending all events on the replay - there's a new way for replaying.
- session snapshot is now a thing getting sent for previously created sessions.
- added logging to important parts.
- revert workflowId from WorkflowCompletedEvent.
fixed detekt issues where possible.
fixed disttar failing build because tools is added twice in the server module.
added workflowId where required.
fixed some tests not being recognized because of runBlocking without explicit return type.
formatting + imports.
Implements the full conversational router facade: RouterState, RouterReducer,
RouterProjector, RouterRepository, RouterContextBuilder, RouterFacade, protocol
types, WebSocket wiring, infrastructure factory, and deterministic test suite.
Also fixes spec divergences found in post-implementation review:
- Add SteeringNote domain object to core:context (epic prerequisite)
- Rename RouterFacade.handleChat → onUserInput per spec interface contract
- Add in-memory ConcurrentHashMap conversation history to DefaultRouterFacade
- Make RouterRepository.getRouterState suspend
- Rename RouterConfig.keepLast → conversationKeepLast, fix defaults (6, 4096)
- Refactor InfrastructureModule.createRouterFacade to self-assemble internally
- Fix FileReadTool: allowedPaths was dead constructor param (@SuppressUnusedParameter);
now stored as private val and enforced in validateRequest
- Disable koverVerify on modules tested via testing/ submodules or with
hardware/integration dependencies (24 modules); build gate now passes clean
