- Introduced `CronAddTool`, `CronListTool`, `CronRemoveTool`, `CronRunTool`, `CronRunsTool`, and `CronUpdateTool` in `src/tools` for adding, listing, removing, running, and updating cron jobs.
- Updated the `run` function in `src/daemon/mod.rs` to conditionally start the scheduler based on the cron configuration.
- Modified command-line argument parsing in `src/lib.rs` and `src/main.rs` to support new cron job commands.
- Enhanced the onboarding wizard in `src/onboard/wizard.rs` to include cron configuration.
- Added tests for cron job tools to ensure functionality and error handling.
* feat: add ZeroClaw firmware for ESP32 and Nucleo
* Introduced new firmware for ZeroClaw on ESP32 and Nucleo-F401RE, enabling JSON-over-serial communication for GPIO control.
* Added `zeroclaw-esp32` with support for commands like `gpio_read` and `gpio_write`, along with capabilities reporting.
* Implemented `zeroclaw-nucleo` firmware with similar functionality for STM32, ensuring compatibility with existing ZeroClaw protocols.
* Updated `.gitignore` to include new firmware targets and added necessary dependencies in `Cargo.toml` for both platforms.
* Created README files for both firmware projects detailing setup, build, and usage instructions.

* feat: enhance hardware peripheral support and documentation
- Added `Peripheral` trait implementation in `src/peripherals/` to manage hardware boards (STM32, RPi GPIO).
- Updated `AGENTS.md` to include new extension points for peripherals and their configuration.
- Introduced comprehensive documentation for adding boards and tools, including a quick start guide and supported boards.

- Updated `Cargo.lock` to remove specific version constraints for several dependencies, including `zerocopy`, `syn`, and `strsim`, allowing for more flexibility in version resolution.
- Upgraded `bincode` and `bitfield` to their latest versions, enhancing serialization and memory management capabilities.
- Updated `Cargo.toml` to reflect the new version of `probe-rs` from `0.24` to `0.30`, improving hardware probing functionality.
- Refactored code in `src/hardware` and `src/tools` to utilize the new `SessionConfig` for session management in `probe-rs`, ensuring better compatibility and performance.
- Cleaned up documentation in `docs/datasheets/nucleo-f401re.md` by removing unnecessary lines.
* fix: apply cargo fmt
* docs: add hardware architecture diagram.

* feat: add screenshot and image_info vision tools
Add two new tools for visual capabilities:
- `screenshot`: captures screen using platform-native commands
(screencapture on macOS, gnome-screenshot/scrot/import on Linux),
returns file path + base64-encoded PNG data
- `image_info`: reads image metadata (format, dimensions, size) from
header bytes without external deps, optionally returns base64 data
for future multimodal provider support
Both tools are registered in the tool registry and agent system prompt.
Includes 24 inline tests covering format detection, dimension extraction,
schema validation, and execution edge cases.

* fix: resolve unused variable warning after rebase
Prefix unused `resolved_key` with underscore to suppress compiler
warning introduced by upstream changes. Update Cargo.lock.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix: address review comments on vision tools
Security fixes:
- Fix JPEG parser infinite loop on malformed zero-length segments
- Add workspace path restriction to ImageInfoTool (prevents arbitrary
file exfiltration via include_base64)
- Quote paths in Linux screenshot shell commands to prevent injection
- Add autonomy-level check in ScreenshotTool::execute
Robustness:
- Add file size guard in read_and_encode before loading into memory
- Wire resolve_api_key through all provider match arms (was dead code)
- Gate screenshot_command_exists test on macOS/Linux only
- Infer MIME type from file extension instead of hardcoding image/png
Tests:
- Add JPEG dimension extraction test
- Add JPEG malformed zero-length segment test

* feat: add OpenTelemetry tracing and metrics observer
Add OtelObserver that exports traces and metrics via OTLP HTTP/protobuf
to any OpenTelemetry-compatible collector (Jaeger, Grafana Tempo, etc.).
- ObserverEvents map to OTel spans (AgentEnd, ToolCall, Error) and
metric counters (AgentStart, ChannelMessage, HeartbeatTick)
- ObserverMetrics map to OTel histograms and gauges
- Spans include proper timing via SpanBuilder.with_start_time
- Config: backend="otel", otel_endpoint, otel_service_name
- Accepts "otel", "opentelemetry", "otlp" as backend aliases
- Graceful fallback to NoopObserver on init failure

* fix: resolve unused variable warning and update Cargo.lock
Prefix unused `resolved_key` with underscore to suppress clippy
warning introduced by upstream changes. Regenerate Cargo.lock
after rebase on main.

* fix: address review comments on OTel observer
- Fix metric types: use Gauge for ActiveSessions/QueueDepth (absolute
readings, not deltas), Counter<u64> for TokensUsed (monotonic)
- Remove duplicate token recording from AgentEnd event handler
(TokensUsed metric via record_metric is the canonical path)
- Store meter_provider in struct so flush() exports both traces
and metrics (was silently dropping metrics on shutdown)

- Fix clippy warnings (is_multiple_of, too_many_lines)
Closes#45
- Fixed E0425 error in src/skills/mod.rs by moving println! inside #[cfg(unix)] block where 'dest' variable is in scope
- Added missing 'identity' field to Config struct initializations in src/onboard/wizard.rs
- Fixed import paths for AIEOS identity functions in src/channels/mod.rs

Resolves issue #28: skills symlink functionality now works correctly on Unix platforms with proper error handling on non-Unix platforms
- Expand communication style presets (professional, expressive, custom)
- Enrich SOUL.md with human-like tone and emoji-awareness guidance
- Add crash recovery and sub-task scoping guidance to AGENTS.md scaffold
- Add 'Use when / Don't use when' guidance to TOOLS.md and runtime prompts
- Implement memory hygiene system with configurable archiving and retention
- Add MemoryConfig options: hygiene_enabled, archive_after_days, purge_after_days, conversation_retention_days
- Archive old daily memory and session files to archive subdirectories
- Purge old archives and prune stale SQLite conversation rows
- Add comprehensive tests for new features
The previous secret store used a repeating-key XOR cipher which is
cryptographically broken:
- Deterministic (no nonce) — identical plaintexts produce identical
ciphertexts
- No authentication — tampered ciphertext decrypts silently
- Vulnerable to known-plaintext attacks (e.g., "sk-" prefix reveals
key bytes)
Replace with ChaCha20-Poly1305 authenticated encryption:
- Random 12-byte nonce per encryption (non-deterministic)
- Poly1305 authentication tag detects tampering
- Uses the same 32-byte key file (no migration needed for keys)
New ciphertext format is `enc2:<hex(nonce || ciphertext || tag)>`.
Legacy `enc:` values (XOR) are still decryptable for backward
compatibility during migration.
Adds chacha20poly1305 0.10 crate (pure Rust, no C dependencies).
New tests: tamper detection, wrong-key rejection, nonce uniqueness,
truncation handling, legacy XOR backward compatibility.
