Matches the patterns used in Omni/Jr/Web.
|
|
Also added HTML escaping for input/output JSON.
|
|
Tools.hs:
- run_bash now uses mkSuccess (applies truncation)
- read_file requires line ranges for files >500 lines
- read_file rejects ranges >400 lines
Engine.hs:
- Added engine-level truncateToolResult (10k char cap)
- Fixed test detection: bash -> run_bash
|
|
- Rewrote system prompt with TOKEN EFFICIENCY section
- Reduced defaults: timeout 600s, maxCost 50ยข, maxTokens 100k
- Added output truncation (8000 char cap) to all tools
- Tightened search limits (30 results, 5 context lines)

Traces are inserted via Memory.withMemoryDb but web server was using
a different path (AVA_DATA_ROOT/ava.db). Now both use getMemoryDbPath.
|
|
|
|
|
|
|
|
The table creation was in Memory.initMemoryDb but Web.hs opened the
database directly without calling it. Now Trace.hs has its own
initTraceDb function that Web.startWebServer calls on startup.

Allows Ava to search her conversation logs for past discussions.

matching, configurable days_back (default 7) and max_results (default 20).

Previously used 'enable --now' which only starts stopped services.
Now explicitly calls 'restart' to ensure running services pick up new versions.
|
|
|
|
The coder role no longer requires task_id, only namespace.
|
|
|
|
- Strengthen Telegram MarkdownV2 formatting guidance in Ava's system prompt
- Add DNS record beryl.bensima.com -> 100.127.197.132 (Tailscale IP)
- Modify push.sh to detect local deploys and skip SSH
- Add Tailscale hostname fallback when domain is unreachable
|

Remove task_id requirement and all jr task CLI calls. The Coder subagent
now only requires namespace and task description - no external task
tracking needed.
Changes:
- Remove coderTaskId from CoderConfig
- Remove jr task show/update/comment calls
- Commit message uses namespace prefix instead of task ID
- Recovery phase just reverts git, no task comment
- Subagent.hs only validates namespace for Coder role
|

Security improvement: subagents now require explicit user confirmation via
Telegram inline buttons, preventing the agent from bypassing approval.
Changes:
- Add InlineKeyboardMarkup, InlineKeyboardButton, CallbackQuery types
- Add parseCallbackQuery for handling button presses
- Add sendMessageWithKeyboard and answerCallbackQuery API functions
- Add PendingSpawn registry for tracking unconfirmed spawn requests
- Add spawnSubagentToolWithApproval that sends approval buttons
- Add handleCallbackQuery to process approve/reject button clicks
- Add approveAndSpawnSubagent and rejectPendingSpawn functions
Flow:
1. Agent calls spawn_subagent โ creates pending request
2. User receives message with โ
Approve / โ Reject buttons
3. Button click (outside agent loop) spawns or cancels
4. Pending requests expire after 10 minutes

conversations while checking on progress via check_subagent.

- Structured output with citations (claim, source_url, quote)
- Separate API keys for OpenRouter vs Kagi

Wrap parser chains in parentheses to fix compilation errors from
incorrect use of </ operator.

The deployer compared its in-memory stateServices map to decide if a
service needed restarting. When the deployer restarted, this state was
lost, causing it to think services were 'already at' the desired path
when they were actually running old code.
Changes:
- Add getRunningStorePath to Systemd module to read actual store path
- Update deployService to query systemd instead of stale in-memory state
- Add DerivingStrategies extension to Deployer.hs
|
|
|
|
- Systemd: use list comprehension instead of if-then-else
- Manifest: use </> operator, replace case with maybe
- Deployer: use newtype, use flip removeService
- Caddy: use newtype for single-field types
|

- Create Omni/Agent/Skills.hs with skill loader and tools
- Skills follow Claude Skills format (SKILL.md + scripts/references/assets)
- Directory structure: _/var/ava/skills/{shared,<user>}/
- Three tools: skill, list_skills, publish_skill
- Users can publish private skills to shared
- Integrate skills tools into Telegram bot
- Create skill-creator meta-skill at _/var/ava/skills/shared/skill-creator/
|

Added retry with backoff, parallel proccessing, editing pages down to main
content, summarization with haiku. It's so much faster and more reliable
now. Plus improved the logging system and distangled the status UI bar from the
logging module.
|
|
- Rename Omni/Bot.hs to Omni/Ava.hs
- Delete Omni/Bot.scm (unused Guile version)

- Deployer: polls S3 manifest, pulls closures, manages systemd units
- Caddy integration for dynamic reverse proxy routes
- bild: auto-cache to S3, outputs STORE_PATH for push.sh
- push.sh: supports both NixOS and service deploys
