infrastructure-hardening SKILL.md skillA
infrastructure-hardening from cooneycw/claude-power-pack is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add cooneycw/claude-power-pack/infrastructure-hardening@git:20260920.677b300Pins git:20260920.677b300 in mdr.lock. Pin the fingerprint instead.

Validation gates, runtime contracts, canary validation and sentinel files. Use after a repeated failure, or for infrastructure hardening, pipeline hardening and SRE pattern work.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Infrastructure Hardening Skill
When repeated infrastructure or pipeline failures are detected, or the user asks about hardening, validation gates, runtime contracts, canary checks, or sentinel files, load the full reference:
```
Read docs/skills/infrastructure-hardening.md
```
## Quick Reference
### Pattern Detection
```python
from lib.cicd.failure_patterns import analyze_failure_patterns
report = analyze_failure_patterns()
if report.has_patterns:
print(report.summary())
```
### Validation Gate Types
| Gate | Use When |
|------|----------|
| Runtime contract | Shell compat, implicit detection, dependency failures |
| Sentinel file | Implicit artifact detection (e.g., `.git` checks) |
| Canary validation | Deploy failures surfacing only in production |
| Auth bootstrap | Repeated credential/permission failures |
| Capability readiness | Services pass ping but fail on first real request |
| Deploy lock | Resource contention on shared infrastructure |
### Key Principle
After 2+ failures from the same root cause: stop patching symptoms, propose systemic hardening.Read the whole file at its exact version.
How to install
mdr add cooneycw/claude-power-pack/infrastructure-hardening@sha256:da980fcb31916d03The line at the top of this page pins the label git:20260920.677b300, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
