What it does

Thoroughness is an agent skill from pr-pm/prpm. Use when implementing complex multi-step tasks, fixing critical bugs, or when quality and completeness matter more than speed - ensures comprehensive implementation without shortcuts through systematic analysis, implementation, and verification phases

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Testing & QA. The repository describes itself as: The universal registry for AI coding tools. The licence is MIT.

When your agent uses it

What it can do on your machine

Read from SKILL.md and the folder at commit 5f993e6. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Thoroughness loads about 1.1k tokens when it runs. Until then it costs about 66 tokens; SKILL.md has 445 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~66
When it runs · the whole SKILL.md, loaded when a task matches: ~1.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description: Use when implementing complex multi-step tasks, fixing critical bugs, or when quality and completeness matter more than speed - ensures comprehensive implementation without shortcuts through systematic analysis, implementation, and verification phases

Thoroughness

Purpose

This skill ensures comprehensive, complete implementation of complex tasks without shortcuts. Use this when quality and completeness matter more than speed.

When to Use

Fixing critical bugs or compilation errors
Implementing complex multi-step features
Debugging test failures
Refactoring large codebases
Production deployments
Any task where shortcuts could cause future problems

Methodology

Phase 1: Comprehensive Analysis (20% of time)

Identify All Issues
- List every error, warning, and failing test
- Group related issues together
- Prioritize by dependency order
- Create issue hierarchy (what blocks what)
Root Cause Analysis
- Don't fix symptoms, find root causes
- Trace errors to their source
- Identify patterns in failures
- Document assumptions that were wrong
Create Detailed Plan
- Break down into atomic steps
- Estimate time for each step
- Identify dependencies between steps
- Plan verification for each step
- Schedule breaks/checkpoints

Phase 2: Systematic Implementation (60% of time)

Fix Issues in Dependency Order
- Start with foundational issues
- Fix one thing completely before moving on
- Test after each fix
- Document what was changed and why
Verify Each Fix
- Write/run tests for the specific fix
- Check for side effects
- Verify related functionality still works
- Document test results
Track Progress
- Mark issues as completed
- Update plan with new discoveries
- Adjust time estimates
- Note any blockers immediately

Phase 3: Comprehensive Verification (20% of time)

Run All Tests
- Unit tests
- Integration tests
- E2E tests
- Manual verification
Cross-Check Everything
- Review all changed files
- Verify compilation succeeds
- Check for console errors/warnings
- Test edge cases
Documentation
- Update relevant docs
- Add inline comments for complex fixes
- Document known limitations
- Create issues for future work

Anti-Patterns to Avoid

❌ Fixing multiple unrelated issues at once
❌ Moving on before verifying a fix works
❌ Assuming similar errors have the same cause
❌ Skipping test writing "to save time"
❌ Copy-pasting solutions without understanding
❌ Ignoring warnings "because it compiles"
❌ Making changes without reading existing code first

Quality Checkpoints

Can I explain why this fix works?
Have I tested this specific change?
Are there any side effects?
Is this the root cause or a symptom?
Will this prevent similar issues in the future?
Is the code readable and maintainable?
Have I documented non-obvious decisions?

Example Workflow

Bad Approach (Shortcut-Driven)

1. See 24 TypeScript errors
2. Add @ts-ignore to all of them
3. Hope tests pass
4. Move on

Good Approach (Thoroughness-Driven)

1. List all 24 errors systematically
2. Group by error type (7 missing types, 10 unknown casts, 7 property access)
3. Find root causes:
   - Missing @types/tar package
   - No type assertions on fetch responses
   - Implicit any types in callbacks
4. Fix by category:
   - Install @types/tar (fixes 7 errors)
   - Add proper type assertions to registry-client.ts (fixes 10 errors)
   - Add explicit parameter types (fixes 7 errors)
5. Test after each category
6. Run full test suite
7. Document what was learned

Time Investment

Initial: 2-3x slower than shortcuts
Long-term: 10x faster (no debugging later, no rework)
Quality: Near-perfect first time
Maintenance: Minimal

Success Metrics

✅ 100% of tests passing
✅ Zero warnings in production build
✅ All code has test coverage
✅ Documentation is complete and accurate
✅ No known issues or TODOs left behind
✅ Future developers can understand the code

Mantras

"Slow is smooth, smooth is fast"
"Do it right the first time"
"Test everything, assume nothing"
"Document for your future self"
"Root causes, not symptoms"
