Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00022 | $0.03343 |
| Opus 5 | $0.00011 | $0.01672 |
| Sonnet 5 | $0.00004 | $0.00669 |
| Haiku 4.5 | $0.00002 | $0.00334 |
Grade A, and why
bad-example-skill 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 11d 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.
How it starts
The opening of the file, as written. The whole thing — 577 lines — stays where its author put it; the contents beside it link to each section on GitHub.
⚠️ BAD EXAMPLE - Interdependent Skill (Anti-Pattern)
WARNING: This is an ANTI-PATTERN example showing what NOT to do.
DO NOT COPY THIS STRUCTURE. See good-self-contained-skill for correct approach.
❌ VIOLATION #1: Relative Path Dependencies
## Related Documentation
For setup instructions, see [../setup-skill/SKILL.md](../setup-skill/SKILL.md)
For testing patterns, see:
- [../../testing/pytest-patterns/](../../testing/pytest-patterns/)
- [../../testing/test-utils/](../../testing/test-utils/)
Database integration: [../../data/database-skill/](../../data/database-skill/)
Why This is Wrong:
- ❌ Uses relative paths (
../,../../) - ❌ Assumes hierarchical directory structure
- ❌ Breaks in flat deployment (
~/.claude/skills/) - ❌ Links break when skill deployed standalone
Correct Approach:
## Complementary Skills
Consider these related skills (if deployed):
- **setup-skill**: Installation and configuration patterns
- **pytest-patterns**: Testing framework and fixtures
- **database-skill**: Database integration patterns
*Note: All skills are independently deployable.*
❌ VIOLATION #2: Missing Essential Content
## Testing
This skill uses pytest for testing.
**See pytest-patterns skill for all testing code.**
To write tests for this framework, install pytest-patterns skill
and refer to its documentation.
Why This is Wrong:
- ❌ No actual testing patterns included
- ❌ Requires user to have another skill
- ❌ Skill is incomplete without other skills
- ❌ "See other skill" instead of inlining
Correct Approach:
## Testing (Self-Contained)
**Essential pytest pattern** (inlined):
```python
import pytest
from example_framework.testing import TestClient
@pytest.fixture
def client():
"""Test client fixture."""
return TestClient(app)
def test_home_route(client):
"""Test homepage."""
response = client.get("/")
assert response.status_code == 200
assert response.json() == {"message": "Hello"}
Advanced fixtures (if pytest-patterns skill deployed):
- Parametrized fixtures
- Database session fixtures
- Mock fixtures
See pytest-patterns skill for comprehensive patterns.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 11d ago First seen · 577 lines · 22 tokens per session scan A 46d0b9820a06
bad-example-skill is a skill published in the GitHub repository bobmatnyc/claude-mpm-skills (74 stars, last pushed 1mo ago), licensed MIT. It adds 22 tokens to every session and 3,343 once invoked, about $0.0001 per session on Opus 5. 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 2026-08-30.
