Use for self-correcting implementation. Implements the reflexion loop: implement, validate, self-critique, retry (max 3 iterations).
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
# Reflexion Skill
Self-correcting implementation loop from the n-trax pattern.
## Workflow
### Iteration Loop (max 3)
**Step 1: Implement**
- Create the deliverable according to the specification/acceptance criteria.
- Software: write code. Content: write/produce content. AI tool: write prompts/configs. Service: document workflow.
- Follow ${CLAUDE_PLUGIN_ROOT}/harness/engineering-principles.md (principles apply to all product types).
- Apply patterns from patterns.md.
- Check corrections.md for relevant past mistakes.
**Step 2: Validate**
- Software: Run tests, linter, type checker, security scan, accessibility checks (if UI).
- **Security validation (OWASP)**: Check input validation, output encoding, parameterized queries, no hardcoded secrets, authentication/authorization patterns, dependency vulnerabilities. Reference OWASP Top 10:2025 categories for each check.
- Content: Review against learning objectives/editorial standards, check accessibility (captions, alt text), fact-check claims.
- AI tool: Run eval test cases, red-team testing, bias assessment.
- Service: Walk through the service blueprint end-to-end, verify documentation completeness.

How to install
mdr add haabe/mycelium/reflexion@sha256:722b96a3d07136b8The line at the top of this page pins the label git:20260704.7639f18, 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.
