PR Threshold Skill

Monitor accumulated commits and metrics to determine when a PR should be pushed for human review. Prevents PRs from becoming too large or complex for effective review.

When to Use

• After each successful git commit
• During Agent Mode commit-level workflow
• Manually with "use pr-threshold skill"

Thresholds

Metric	Trigger Value	Rationale
Lines of Code	> 300	Human cognitive limit
Files Changed	> 10	Context switching cost
Commits	> 5	Review complexity
Risk Score	HIGH	Needs careful review
Scope Completion	100%	Feature complete

Phase 1: Gather Metrics

1.1 Lines of Code

git diff origin/develop --stat | tail -1

Extract: insertions + deletions

1.2 Files Changed

git diff origin/develop --name-only | wc -l

1.3 Commit Count

git rev-list origin/develop..HEAD --count

1.4 Risk Score

Sum of risk from pr-review across all commits:

• LOW = 1
• MEDIUM = 2
• HIGH = 3

1.5 Scope Completion

From Commit Plan:

• Total commits planned: N
• Commits completed: M
• Completion: M/N * 100%

Phase 2: Evaluate Thresholds

## PR Threshold Check

| Metric | Current | Threshold | Status |
|--------|---------|-----------|--------|
| Lines of Code | [N] | 300 | OK/CROSSED |
| Files Changed | [N] | 10 | OK/CROSSED |
| Commits | [N] | 5 | OK/CROSSED |
| Risk Score | [N] | HIGH | OK/CROSSED |
| Scope Completion | [N]% | 100% | OK/CROSSED |

Phase 3: Determine Action

CONTINUE (No threshold crossed)

## Verdict: CONTINUE

No thresholds crossed. Proceeding to next commit.

### Current Accumulation:
- LOC: [N]/300
- Files: [N]/10
- Commits: [N]/5
- Scope: [N]%

### Next Commit:
[Name of next commit from plan]

TRIGGER_PR (Threshold crossed)

## Verdict: TRIGGER_PR

**Threshold crossed:** [Which metric(s)]

### Recommendation:
Push PR now for human review before continuing.

### PR Scope:
- Commits: [List of commit names]
- Total LOC: [N]
- Files: [N]
- Risk: [LOW/MEDIUM/HIGH]

### Remaining Work:
- Commits left: [N]
- Features incomplete: [List]

**Proceed to push-pr mode?** (Yes / Continue anyway)

BLOCK (Threshold crossed, no override)

If threshold crossed and user has NOT provided explicit override:

## Verdict: BLOCK

**Threshold crossed:** [Which metric(s)]

IMPLEMENTATION PAUSED - User decision required.

| Option | Action |
|--------|--------|
| A | Push PR now (recommended) |
| B | Continue anyway (override logged) |

Reply with A or B to proceed.

Do NOT continue until user responds. This is a hard stop per 00-hard-rules.mdc.

Phase 4: Handle Decision

If TRIGGER_PR

1. Present metrics summary
2. Recommend push-pr mode
3. If user approves: Switch to push-pr mode
4. If user continues: Log override, proceed

If CONTINUE

1. Proceed to next commit in plan
2. Update accumulated metrics

Threshold Overrides

User can override thresholds with explicit confirmation:

**Warning:** LOC threshold exceeded (350/300).

Continuing without PR may make review harder.

**Override and continue?** (Yes / Push PR now)

Log overrides for later review.

Integration

This skill is invoked by:

• agent.mdc - After each successful commit
• commit.mdc - After commit completes

Metrics Storage

Track across commits:

Accumulated Metrics:
- Total LOC: [running sum]
- Total Files: [unique count]
- Commit Count: [N]
- Highest Risk: [LOW/MEDIUM/HIGH]
- Started: [timestamp]

Reset after successful PR push.

Output Format

## PR Threshold Status

**Verdict:** [CONTINUE / TRIGGER_PR]

| Metric | Value | Threshold | % |
|--------|-------|-----------|---|
| LOC | [N] | 300 | [N]% |
| Files | [N] | 10 | [N]% |
| Commits | [N] | 5 | [N]% |
| Scope | [N]% | 100% | [N]% |

[Action recommendation]

Invocation

Invoked automatically after each commit, or manually with "use pr-threshold skill".
