+# Context - Feature Proposer Agent Run
+
+**Agent**: feature-proposer-agent
+**Cadence**: weekly
+**Run-Start**: 2026-02-17T15:00:00Z
+**Prompt-Path**: src/prompts/weekly/feature-proposer-agent.md
+
+## Goal
+Implement a new feature to improve developer experience.
+
+## Scope
+Create a new feature in `features/` directory.
+
+## Constraints
+Single file, no new dependencies.
+
+## Analysis
+- The repository has a `task-logs/` directory with daily and weekly logs.
+- Checking these logs manually is tedious.
+- A simple CLI tool to summarize these logs would be high-value and low-risk.
+- Prompt file: `src/prompts/weekly/feature-proposer-agent.md`.
+
+## Selected Feature
+- `features/log-summary.mjs`: A Node.js script to parse and display a summary of recent agent runs.
+
+## Implementation Details
+- Uses `fs` and `path` modules.
+- Scans `task-logs/daily` and `task-logs/weekly`.
+- Parses filenames `<timestamp>__<agent>__<status>.md`.
+- Outputs a formatted ASCII table.

+# Decisions - Feature Proposer Agent Run
+
+**Agent**: feature-proposer-agent
+**Cadence**: weekly
+**Run-Start**: 2026-02-17T15:00:00Z
+**Prompt-Path**: src/prompts/weekly/feature-proposer-agent.md
+
+## Decision: Implement `features/log-summary.mjs`
+
+### Context
+Developers and agents need a quick way to see the recent history of automated tasks without navigating the file system. Prompt: `src/prompts/weekly/feature-proposer-agent.md`.
+
+### Options Considered
+1. **Dashboard Widget**: Requires frontend changes, more complex.
+2. **Lock Monitor**: Already covered by `lock:check`.
+3. **Log Summary CLI**: Simple, standalone, immediate value.
+
+### Decision
+Chosen Option 3 (Log Summary CLI).
+
+### Rationale
+- Fits the "single file" constraint perfectly.
+- No external dependencies required.
+- High utility for checking system health at a glance.
