3_validate_plan

3_validate_plan is a command for coding agents from seekayel/claude-plugins. It costs 0 tokens per session (700 once invoked), scanned A, original, MIT.

A command for checking whether an implementation plan was carried out correctly and whether its stated success conditions were met.

In plain words
What is it for?
Use it to review the plan, inspect the changed files and tests, run the listed verification commands, and report which requirements passed or failed.
Why use it?
It helps find missing work, deviations, failing tests, or unsupported claims after an implementation is reported as complete.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

3_validate_plan scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Validate Plan

You are tasked with validating that an implementation plan was correctly executed, verifying all success criteria and identifying any deviations or issues.

Initial Setup

When invoked:

  1. Determine context - Review what was implemented
  2. Locate the plan - Find the implementation plan document
  3. Gather implementation evidence through git and testing

Validation Process

Step 1: Context Discovery

  1. Read the implementation plan completely

  2. Identify what should have changed:

    • List all files that should be modified
    • Note all success criteria (automated and manual)
    • Identify key functionality to verify
  3. Spawn parallel research tasks to discover implementation:

    • Verify code changes match plan specifications
    • Check if tests were added/modified as specified
    • Validate that success criteria are met

Step 2: Systematic Validation

For each phase in the plan:

  1. Check completion status:

    • Look for checkmarks in the plan (- [x])
    • Verify actual code matches claimed completion
  2. Run automated verification:

    • Execute each command from "Automated Verification"
    • Document pass/fail status
    • If failures, investigate root cause
  3. Assess manual criteria:

    • List what needs manual testing
    • Provide clear steps for user verification

Step 3: Generate Validation Report

Create comprehensive validation summary:

## Validation Report: [Plan Name]

### Implementation Status
✓ Phase 1: [Name] - Fully implemented
✓ Phase 2: [Name] - Fully implemented
⚠️ Phase 3: [Name] - Partially implemented (see issues)

### Automated Verification Results
✓ Build passes
✓ Tests pass
✗ Linting issues (3 warnings)

### Code Review Findings

#### Matches Plan:
- [What was correctly implemented]
- [Another correct implementation]

#### Deviations from Plan:
- [Any differences from plan]
- [Explanation of deviation]

#### Potential Issues:
- [Any problems discovered]
- [Risk or concern]

### Manual Testing Required:
1. UI functionality:
   - [ ] Verify feature appears correctly
   - [ ] Test error states

2. Integration:
   - [ ] Confirm works with existing components
   - [ ] Check performance

### Recommendations:
- [Action items before merge]
- [Improvements to consider]

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

3_validate_plan is a command published in the GitHub repository seekayel/claude-plugins (2 stars, last pushed 7mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 700 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
