Architecture metadata fetch timing (cmd/late-sast/main.go) - Add retry loop (3 attempts, 200ms apart) inside fetchMetaOnce to absorb brief MCP startup lag without waiting for the next subagent spawn. - Guard against all-zero ComplexityMeta (repo not yet indexed): treat empty data as a failed fetch so metaFetched stays false and we keep retrying. Previously a zero-metric success response would lock in a wrong budget. 2. Merge docker inspect round-trips in launch_docker.go - Add inspectNameAndPorts(): single 'docker inspect -f' call returning both .Name and .NetworkSettings.Ports via delimited template, replaces two serial calls in launchCompose. - Add inspectIDAndPorts(): same for launchDockerfile (Id + Ports). - Add parsePortsJSON() helper used by both. - Saves one docker exec per launch invocation. - Update launch_docker_test.go stubs to match the new combined template. 3. --tui flag clarification (cmd/late-sast/main.go) - Update flag description: it no longer switches to a TUI mode, it just keeps stdout/stderr on the terminal instead of redirecting to the log file. - Remove stale 'TUI mode removed' comment. --- cmd/late-sast/main.go | 42 +++++++++++++-- internal/tool/launch_docker.go | 84 ++++++++++++++++++++++++++--- internal/tool/launch_docker_test.go | 10 ++-- 3 files changed, 117 insertions(+), 19 deletions(-) diff --git a/cmd/late-sast/main.go b/cmd/late-sast/main.go index 4478ad4..766b7d4 100644 --- a/cmd/late-sast/main.go +++ b/cmd/late-sast/main.go @@ -57,7 +57,7 @@ func main() { pathReq := flag.String("path", "", "Path to a local repository to audit (alternative to a GitHub URL)") retestReq := flag.String("retest", "", "Path to a previous SAST report — retests all confirmed findings to check if they have been fixed") - useTUIReq := flag.Bool("tui", false, "Use terminal UI instead of the graphical interface") + useTUIReq := flag.Bool("tui", false, "Keep stdout/stderr on the terminal instead of redirecting to ~/.cache/late-sast/late-sast.log (GUI always launches)") flag.Usage = func() { fmt.Fprintf(os.Stderr, "Usage: late-sast [flags]\n\n") @@ -365,8 +365,15 @@ func main() { // Lazily fetch architecture metadata from get_architecture on each subagent // spawn until one succeeds.

Fix ToolResultCache.Get TOCTOU race: re-read entry under write lock before deleting to avoid killing a concurrently-refreshed valid entry - Thread onToolState into executeParallelBatch so GUI shows tool status for parallel read batches (was silently skipped) - Add toolcache_test.go with TTL/InvalidateAll/concurrent-Set coverage session: - Replace static toolRequiresArgs list with JSON-schema introspection via t.Parameters() so it stays accurate as tools are added/removed - Fix ListSessions sort order: descending (newest first) to match browser UX orchestrator: - Extract prepareContext() and doRunLoop() from Execute/run to eliminate ~80 lines of copy-pasted RunLoop setup gui: - Remove duplicate formatSubagentContextUsage; all sites use formatContextUsage - Extract finalize closure in events.go; fix idle double-enable bug and closed path missing streaming flag reset debug: - Logger now lazy-opens the log file on first write and holds the fd open for the lifetime of the logger instead of reopening on every logEntry call - Add Close() method for explicit cleanup - Fix LogToolResultWithMeta redundant intermediate map mcp: - Connect() now takes a name parameter so ConnectFromConfig sessions are stored by server name; previously every server overwrote the 'default' key, leaking N-1 connections and dropping all but the last server's tools --- .gitignore | 1 -

Ask yourself: -* What files need to be modified? -* What new files need to be created? -* How can this be broken down into atomic, verifiable steps? -* Are there any **Agent Skills** (e.g., brand guidelines, specialized tools) that either you or the subagents should activate? - -### Phase 3: Architectural Stress Test & Conflict Resolution -Before generating the final output, you must internally simulate the execution of your plan. -1. **Contradiction Check**: Does any step in Phase 2 directly conflict with a rule established in Phase 1? (e.g., removing a parameter but adding a CLI flag for it later). -2. **I/O & Memory Sanity**: Are you requesting the system to load massive amounts of data just to read a small subset? If so, specify the exact memory-efficient parsing method. -3. **Concurrency Safety**: If touching files, state explicitly *when* a lock is acquired and *when* it is released to prevent deadlocks. - -### Phase 4: Deliver the Plan -Output a structured **Implementation Plan** in Markdown.

The actual registered tool names are 'patch_compose_network' and 'target_edit'. Because mutatesWorkspace() never matched these tools, cache.InvalidateAll() was never called after a target_edit or patch_compose_network call, causing subsequent read_file results to be served from the pre-edit cache — the LLM would see stale file content after every targeted edit or compose patch. Also fix a spurious StopRequestedEvent in BaseOrchestrator.Submit(): if Cancel() was called after the previous run had already completed normally, stopCh held a residual signal. The next Submit()→run() would drain it via IsStopRequested() at run end and emit a StopRequestedEvent for a run that was never cancelled.
