[BUG] recent_activity prompt always returns "0 projects" regardless of actual activity

recent_activity MCP prompt always returns "0 projects" regardless of actual activity

Description

The recent_activity MCP prompt returns "Found activity across 0 projects" even when the recent_activity MCP tool returns valid
results for the same timeframe.

Steps to Reproduce

1. Have existing activity in Basic Memory (notes, observations, etc.)
2. Invoke the MCP prompt via Claude Code: /basic-memory:recent_activity 4d
3. Observe the output shows "Found activity across 0 projects"
4. Call the MCP tool with the same timeframe: recent_activity(timeframe="4d")
5. Observe the tool correctly returns activity data

Expected Behavior

The recent_activity prompt should display the same activity data that the tool returns, formatted for the conversation context.

Actual Behavior

The prompt always returns:
Found activity across 0 projects. Most active: Unknown

...followed by a template suggesting the user create a cross-project summary, rather than showing actual activity.

Environment

• Basic Memory version: 0.16.2
• Client: Claude Code CLI
• OS: macOS (Darwin 25.2.0)

Additional Context

Method	Timeframe	Result
Prompt	1d	"0 projects" ❌
Prompt	4d	"0 projects" ❌
Tool	4d	10 items found ✅
Tool	7d	10 items found ✅

The tool correctly finds activity in the "main" project, but the prompt appears to not be receiving or rendering this data.

Possibly related: the prompt also fails with "Error rendering prompt recent_activity" when timeframe is omitted, even though the tool
handles missing timeframe gracefully (defaults to 7d).

Just a heads-up: the Claude Issue Triage workflow (#97) failed when this issue was opened. Might be worth checking the CLAUDE_CODE_OAUTH_TOKEN secret.
