* fix: remove redundant tools definitions from system prompt
Tools are already provided to the LLM via JSON schema through
ToProviderDefs(), so the text-based tools section in the system
prompt is redundant.
This removes the buildToolsSection() logic and the tools field
from ContextBuilder, reducing system prompt length while maintaining
the "ALWAYS use tools" rule reminder.

Whitespace is a linter that checks for unnecessary newlines at the start and end of functions, if, for, etc.

* refactor(cli): migrate to Cobra-based command structure
Refactor CLI to use Cobra instead of manual os.Args parsing.
- Introduce root command and structured subcommands under cmd/picoclaw/internal
- Convert agent, auth, cron, gateway, migrate, onboard, skills, status and version to Cobra commands
- Replace manual flag parsing with Cobra flags
- Remove direct os.Args usage from command handlers
- Keep existing command behavior and output semantics
This change focuses on CLI structure and maintainability.
No business logic changes intended.
* chore(cli): remove version2 alias and make cobra a direct dependency
* test(cli): add basic command tests
- Add tests for CLI command tree and flag parsing
- Align LDFLAGS injection path for version info
- Remove unused manual help function
* test: migrate command tests to testify assertions
Replace standard library testing error checks (t.Error*, t.Fatalf)
with assert/require from stretchr/testify across all cobra command tests
for improved readability and consistency.
* fix(cli): make linter happy
* test: avoid duplication in windows config path test
* test: simplify allowed command checks using slices.Contains
* fix(skills): register subcommands during command construction
- Move subcommand registration out of PersistentPreRunE
- Ensure `picoclaw skills <subcommand>` resolves correctly
- Minor install command and test cleanups
* refactor(cli): address review feedback and improve command clarity
* fix(authLogoutCmd): rm os.Exit
Avoid rebuilding the entire system prompt on every BuildMessages() call
by caching the static portion (identity, bootstrap, skills summary,
memory) and only recomputing it when workspace source files change.
Key changes:
- ContextBuilder caches the static prompt behind an RWMutex with
double-checked locking. Source file changes are detected via cheap
os.Stat mtime checks so no explicit invalidation is needed.
- Track file existence at cache time (existedAtCache map) so that
newly created or deleted bootstrap/memory files also trigger a
rebuild — the old modifiedSince() silently returned false on
os.IsNotExist.
- Walk the skills directory recursively with filepath.WalkDir to
catch content-only edits at any nesting depth; directory mtime
alone misses in-place file modifications on most filesystems.
- ToolRegistry.sortedToolNames() sorts tool names before iteration,
ensuring deterministic tool definition order across calls — a
prerequisite for LLM-side prefix/KV cache reuse.
- Merge all context (static + dynamic + summary) into a single
system message for provider compatibility: the Anthropic adapter
extracts messages[0] as the top-level system parameter, and Codex
reads only the first system message as instructions.
- Fix a data race in BuildMessages() where cachedSystemPrompt was
read without holding the lock in a debug log statement.
- Add tests: single system message invariant, mtime auto-invalidation,
new-file creation detection, skill file content change, explicit
InvalidateCache, cache stability, concurrent access (20 goroutines
x 50 iterations, passes go test -race), and a benchmark.
The spawn tool accepts empty strings as valid task arguments, which
causes a subagent to run with no meaningful work. The subagent's
completion message is then routed back to the originating channel
(e.g. Signal, Discord), where the main agent processes it and may
hallucinate an unrelated response that gets sent to users.
Validate that the task parameter is non-empty after trimming whitespace.

Walk backwards over preceding tool messages to find the nearest assistant
with ToolCalls, instead of only checking the immediate predecessor. Add
unit tests for sanitizeHistoryForProvider covering key edge cases.
