Telemetry PR Insights

Scope

Default: Branch Lifetime

1. •Find merge-base: git merge-base HEAD origin/main
2. •Get timestamp: git show -s --format=%cI <merge_base>
3. •Query events where timestamp >= branch_start for current workspace

Fallback: Last 7 Days

If Git unavailable or merge-base fails.

Data Access (Combined Platforms)

Database: ~/.blueplane/telemetry.db

• •

  Claude Code (claude_raw_traces):

  • •Filter by cwd LIKE '/path/to/workspace%'
  • •Tokens: input_tokens, cache_creation_input_tokens, cache_read_input_tokens, output_tokens
  • •Model: message_model, Role: message_role, Branch: git_branch
• •

  Cursor (cursor_sessions + cursor_raw_traces):

  • •Step 1: Get workspace_hash from cursor_sessions WHERE workspace_path LIKE '/path/to/workspace%'
  • •Step 2: Get composer_ids from cursor_raw_traces WHERE event_type='composer' AND workspace_hash=?
  • •Step 3: Filter bubbles by composer_id extracted from item_key = "bubbleId:{composerId}:{bubbleId}"
  • •Tokens: token_count_up_until_here (cumulative only; use for activity, not precise totals)
  • •Message type: message_type (0=user, 1=assistant, often NULL for ~all events)
  • •Model: not stored (always treated as unknown)

For full schema details, see the Data Access / Schema Reference section in telemetry-insights/SKILL.md. This skill uses the same combined Cursor + Claude access patterns, but scoped to the PR branch window.

Tool Usage & Workflow Patterns (Claude Code only)

Data source: Decompress event_data blob from claude_raw_traces

import zlib, json
decompressed = zlib.decompress(row['event_data'])
event = json.loads(decompressed)
tools = event['payload']['entry_data']['message']['content']
# Filter: item['type'] == 'tool_use'
# Extract: item['name'], item['input']['file_path'], item['input']['command']

Tool operation churn (detect both productive and unproductive patterns):

Negative patterns (wasted effort):

• •Files written then deleted without commit (e.g., created but not in git)
• •Same file edited multiple times in short succession (trial-and-error)
• •Bash commands repeated with similar patterns (debugging loops)
• •Write operations for files later removed (unwanted artifacts)

Positive patterns (intentional iteration):

• •Progressive refinement: Write → Read → Edit (deliberate improvement)
• •Test-driven flow: Write test → Run → Edit code → Run (TDD cycle)
• •Exploration: Multiple Read/Grep before Write (research-based development)
• •Read-before-edit ratio > 0.8 (careful, informed changes)

Workflow efficiency signals:

• •Tool distribution (Bash, Write, Edit, Read, Task usage)
• •Read-before-edit ratio (higher = more careful)
• •File touch count (edits per unique file path)
• •Time between tool uses (rapid = reactive, spaced = deliberate)

Cross-reference with git to classify churn:

• •Compare Write/Edit file paths against final committed files
• •Flag operations on files not in git diff --name-only
• •Distinguish exploration (positive) from mistakes (negative)

Derived Insights (3-5 max)

• •Efficiency: token ratio, cache usage, assessment (Claude Code only)
• •Activity Pattern: steady/bursty/spiky, platform distribution
• •Model Strategy: dominant model, cost awareness (Claude Code only)
• •Platform Usage: Claude Code vs Cursor breakdown, workflow insights
• •Workflow Quality: Tool usage patterns, churn classification (productive vs wasteful), read-before-edit discipline

Output Format

Executive Summary (2-4 sentences)

First sentence MUST state time frame:

• •"Since this branch diverged from main on YYYY-MM-DD, ..."
• •"Over the last 7 days, ..."

Then: activity level, efficiency, standout patterns.
