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 | $0.00050 | $0.00277 |
| Opus 5.5 | $0.00020 | $0.00111 |
| Sonnet 5.5 | $0.00010 | $0.00055 |
| Haiku 4.5 | $0.00005 | $0.00028 |
Grade A, and why
environment-config-review 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 1mo 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.
What it actually says
Environment Config Review
Core Workflow
- Identify environments, config sources, secret stores, feature flags, owners, and runtime consumers.
- Inventory required, optional, deprecated, and sensitive settings.
- Check parity and drift across local, CI, staging, preview, and production.
- Review validation, defaults, type safety, missing value behavior, and secret handling.
- Recommend config docs, schema validation, redaction, and approval gates.
- Flag risky changes before deployment.
Safety Rules
- Do not print or commit secret values.
- Do not change production config, flags, or secrets without explicit approval.
- Do not assume local defaults are safe for production.
Deliverable Shape
For config reviews, provide:
- Environment scope
- Config inventory
- Required and sensitive settings
- Drift and parity risks
- Validation and default behavior
- Secret handling notes
- Required changes
- Approval gates
References
- Read

What ships with it
2 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.

environment-config-review is a skill published in the GitHub repository jeremylongworth-source/AgentSkills (1 stars, last pushed 17d ago), licensed MIT. It adds 50 tokens to every session and 277 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
