Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 14 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00023 | $0.03455 |
| Opus 5.5 | $0.00009 | $0.01382 |
| Sonnet 5.5 | $0.00005 | $0.00691 |
| Haiku 4.5 | $0.00002 | $0.00346 |
Grade B, and why
claude-code-proxy-patterns scanned grade B with 3 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 14d 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

Claude Code Proxy Patterns
Multi-provider proxy that routes Claude Code model tiers to different backends. Haiku to a cheaper Anthropic-compatible provider (cost/speed), Sonnet/Opus to Anthropic (native OAuth passthrough). Includes Go binary proxy with launchd auto-restart and failover wrapper for resilience.
Scope: Local reverse proxy for Claude Code with OAuth subscription (Max plan). Routes based on model name in request body.
Reference implementations:
- Go proxy binary:
/usr/local/bin/claude-proxy(port 8082)
Self-Evolving Skill: This skill improves through use. If instructions are wrong, parameters drifted, or a workaround was needed — fix this file immediately, don't defer. Only update for real, reproducible issues.
When to Use This Skill
- Building or debugging a Claude Code multi-provider proxy
- Setting up
ANTHROPIC_BASE_URLwith OAuth subscription mode - Integrating Anthropic-compatible providers
- Diagnosing "OAuth not supported" or auth failures through a proxy
- Understanding how Claude Code stores and transmits OAuth tokens
Do NOT use for: Claude API key-only setups (no proxy needed), MCP server development, Claude Code hooks (operate at tool level, not API level), or corporate HTTPS proxy traversal.

What ships with it
7 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.

claude-code-proxy-patterns is a skill published in the GitHub repository terrylica/cc-skills (0 stars, last pushed today), licensed MIT. It adds 23 tokens to every session and 3,455 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it B with 3 findings (asks for root, makes network calls, runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
