waza: Skill for Claude Code

.copilot/skills/secret-handling/SKILL.md

secret-handling is a skill for Claude Code, Codex from microsoft/waza. It costs 19 tokens per session (1,998 once invoked), scanned A, a copy of secret-handling, MIT.

Rules for protecting secrets during agent work, especially credentials stored in environment files and files that agents may commit.

In plain words
What is it for?
Use it whenever repository configuration or agent-generated records might involve environment files, credentials, or sensitive data.
Why use it?
It prevents live credentials from being read and accidentally exposed in logs, shared files, or version history.

Written for no agent in particular: nothing here depends on one.

This is microsoft/waza's own configuration. It tells Claude Code and Codex how to work on waza itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything waza configures →

About the project

microsoft/waza is a Go command-line tool for building and evaluating AI agent skills through test suites, benchmarks, and model comparisons. It is for developers who need to measure and improve how reliably agent skills work. The catalogue entries are Waza's own skills, instructions, agent, and MCP integration.

Token cost

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.

Security

Grade A, and why

secret-handling 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 8d 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.

Origin

This is a copy

100% identical to secret-handling — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 201 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Context

Spawned agents have read access to the entire repository, including .env files containing live credentials. If an agent reads secrets and writes them to .squad/ files (decisions, logs, history), Scribe auto-commits them to git, exposing them in remote history. This skill codifies absolute prohibitions and safe alternatives.

Patterns

Prohibited File Reads

NEVER read these files:

  • .env (production secrets)
  • .env.local (local dev secrets)
  • .env.production (production environment)
  • .env.development (development environment)
  • .env.staging (staging environment)
  • .env.test (test environment with real credentials)
  • Any file matching .env.* UNLESS explicitly allowed (see below)

Allowed alternatives:

  • .env.example (safe — contains placeholder values, no real secrets)
  • .env.sample (safe — documentation template)
  • .env.template (safe — schema/structure reference)

If you need config info:

  1. Ask the user directly — "What's the database connection string?"
  2. Read .env.example — shows structure without exposing secrets
  3. Read documentation — check README.md, docs/, config guides

NEVER assume you can "just peek at .env to understand the schema." Use .env.example or ask.

Prohibited Output Patterns

NEVER write these to .squad/ files:

Pattern Type Examples Regex Pattern (for scanning)
API Keys OPENAI_API_KEY=sk-proj-..., GITHUB_TOKEN=ghp_... `[A-Z_]+(?:KEY
Passwords DB_PASSWORD=super_secret_123, password: "..." `(?:PASSWORD
Connection Strings postgres://user:pass@host:5432/db, Server=...;Password=... `(?:postgres
JWT Tokens eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9... eyJ[A-Za-z0-9_-]+\.eyJ[A-Za-z0-9_-]+\.[A-Za-z0-9_-]+
Private Keys -----BEGIN PRIVATE KEY-----, -----BEGIN RSA PRIVATE KEY----- -----BEGIN [A-Z ]+PRIVATE KEY-----
AWS Credentials AKIA..., aws_secret_access_key=... `AKIA[0-9A-Z]{16}
Email Addresses [email protected] (PII violation per team decision) [a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}

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.
