adversarial-performance — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited adversarial-performance (Agent Skill) and scored it 82/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 2 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

The primary manifest — the file an agent reads to learn what this artifact does.
A multi-pass performance auditing system that produces high-confidence optimization assessments by introducing structured adversarial critique stages. Audits pass through an iterative pipeline of profiling, stress-testing critique, optimization planning, and optional external validation — producing output optimized for measurable impact, effort efficiency, and regression safety.

Before starting, auto-detect the project profile by scanning the repository:
| Signal | Project Profile | Extra Categories |
|---|---|---|
MCP SDK imports, tool handlers, tools/list | mcp-server | Token & Context Efficiency (Category 7) — full depth |
Express/Hono/Fastify, HTTP handlers, listen() | web-app | Runtime Performance (Category 4) — extra API latency focus |
bin field, CLI arg parsing | cli-tool | Startup Cost analysis in Category 4 |
| Vitest/Jest/Playwright config | tested | Test Suite Performance (Category 5) — full depth |
| Dockerfile present | containerized | Build Performance (Category 1) — Docker layer analysis |
| Database imports (better-sqlite3, pg, mysql2) | data-layer | Database & I/O (Category 6) — full depth |
Profiles stack. A typical MCP server might be mcp-server + cli-tool + tested + containerized + data-layer.
This skill follows the standard dual-agent adversarial pattern (Agent A: The Profiler, Agent B: The Stress Tester). For the core pipeline rules, phase definitions, and agent switching protocols, read: [../adversarial-security/references/adversarial-base-protocol.md](../adversarial-security/references/adversarial-base-protocol.md)
For the performance-specific protocol with review dimensions, scoring weights, and output templates, read: [references/multi-pass-performance-protocol.md](references/multi-pass-performance-protocol.md)
The 7 performance categories audited during Phase 1 (Profiling) and challenged during Phase 2 (Stress Test) are:
For the full checklist with measurement methods, anti-patterns, and optimization patterns, read references/audit-categories.md.
Phase 4 triggers an independent validation pass using the GitHub CLI (gh copilot). This provides a fundamentally different model's perspective on the audit, catching performance patterns that internal review normalizes.
For Copilot-specific prompt templates, read references/copilot-performance-prompts.md.
Prerequisites: gh CLI v2.x+ with gh auth status passing. If gh copilot is not available, skip Phase 4 gracefully and note the skip in the journal entry.
Read references/copilot-usage.md for critical non-interactive execution requirements.
Every phase creates a journal entry with structured tags and entry types. This builds a searchable audit trail that tracks performance evolution across releases.
For journal templates, tag conventions, and retrospective templates, read references/feedback-loop.md.
See references/journal-opt-out.md for instructions on how to handle explicit opt-outs from journaling.
The final deliverable is a single consolidated artifact merging all four phases into one document. Do NOT produce separate artifacts per phase — the user should receive one comprehensive document with all findings, optimizations, and external validation results. Before sharing output outside the audit context, redact or generalize sensitive query patterns, specific API payloads, and avoid including live credentials or internal hostnames.

| Skill/Workflow | Relationship |
|---|---|
adversarial-security | Sibling skill — applies adversarial pattern to security; this applies it to performance |
adversarial-planner | Parent pattern — plan-level adversarial review; this and security extend it to audits |
autonomous-dev | Generator/Evaluator pipeline at code level; use after this skill to implement optimizations |
/perf-audit workflow | Provides the category checklist; this skill adds adversarial methodology on top |
web-perf | Web-specific performance skill; use alongside for frontend-heavy projects |
