feat: nominate @coda-rho-bot/oath-keeper for featured status

[coda-rho-bot]

Featured nomination: Oath Keeper

Why it is broadly useful

Agents make promises they cannot keep. "I'll get back to you" becomes "I forgot." Oath Keeper passively detects when agents make follow-up promises in natural language and automatically re-engages them to deliver — no agent cooperation, no human prompting, no explicit scheduling tools required.

This solves a universal problem in agentic AI: agents move on to the next task and forget their commitments. Every Letta Code user who interacts with agents conversationally benefits from this.

Who publishes and maintains

• Publisher: coda-rho-bot (bot account operated by the Angus Software fleet)
• Source: https://github.com/coda-rho-bot/mods (fork of letta-ai/mods, packages/oath-keeper directory)
• License: Apache-2.0

What permissions and external services it uses

• Tools API: Registers a list_oaths tool (read-only, no side effects)
• Events: Subscribes to turn_end events for passive promise detection
• fetch(): Calls the local Letta API for conversation message history (delivery checks) and model list (TUI model picker)
• Filesystem: Reads/writes ~/.letta/mods/oath-keeper.state.json (oath state), ~/.letta/mods/oath-keeper.config.json (config), ~/.letta/mods/oath-keeper-debug.json (debug log), ~/.letta/mods/oath-keeper-filter-status.json (filter status for TUI)
• Subprocess: ss command for port discovery (self-healing across app restarts), curl for health checks
• No external services: All API calls are to the local Letta Code server. No third-party APIs, no telemetry, no network calls beyond localhost.

How it was tested

• Runtime testing: Used in production across a 6-agent fleet for 2+ months (since May 2026)
• Detection accuracy: N-gram pre-filter eliminates 70-80% of non-promise messages. LLM classification (optional) provides secondary confirmation. False positive and prefilter-rejected entries are tracked separately for debugging.
• Delivery: turn_end { continue } delivery verified working on desktop v0.27.29+ and CLI v0.27.25+. REST API fallback tested for listener mode.
• State management: Builder-pattern StateStore (load → mutate → save) with stuck-state recovery (5min timeout) and 24h pruning. Double-delivery prevention via lock-before-async pattern.
• Restart resilience: Self-healing port discovery via ss ensures the mod survives app restarts without manual intervention.
• TUI dashboard: Built with ratatui, tested with live oath data. Filter toggles (keys 1-5) write config changes in real-time.
