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.

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 | $0.00019 | $0.01998 |
| Opus 5 | $0.00010 | $0.00999 |
| Sonnet 5 | $0.00004 | $0.00400 |
| Haiku 4.5 | $0.00002 | $0.00200 |
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 12d 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.
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:
- Ask the user directly — "What's the database connection string?"
- Read
.env.example— shows structure without exposing secrets - 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.

secret-handling is a skill published in the GitHub repository elbruno/ElBruno.MempalaceNet (11 stars, last pushed 2mo ago), licensed MIT. It adds 19 tokens to every session and 1,998 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to secret-handling, differing in 0 lines, and is treated as a copy.
