manage-puffo-env-vars from puffo-ai/puffo-agent is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Add, rename, migrate, or review Puffo-owned environment variables and their config precedence. Use when touching `PUFFO_*` variables, raw `os.getenv` or `os.environ` reads, test/debug switches, deployment overrides, or environment-to-config migrations.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Manage Puffo Environment Variables
First decide whether the setting belongs in daemon/agent config, a CLI flag, or
an environment variable. User-facing persistent behavior belongs in config;
environment variables are for deployment, expert, debug, or test overrides.
## Ownership
- Centralize Puffo-owned variables behind typed accessors. Do not add another
scattered `os.getenv("PUFFO_...")` call.
- Read operating-system and upstream variables such as `HOME`, `PATH`,
`CODEX_*`, provider variables, and proxy variables as external inputs rather
than registering them as Puffo-owned settings.
- Give each Puffo variable one parser, default, owner, and precedence rule.
- In tests, restore the exact prior environment after an override.
## Naming And Migration
Use the `PUFFO_` prefix and a name that describes positive behavior. Avoid
double-negative flags. For a rename, accept the old name at one boundary,
prefer the new name when both exist, and emit a deprecation warning. Do not
silently change the default during a rename.
Trace environment values through subprocess and container inheritance. Record
whether a value is intentionally forwarded, translated into config, or kept

How to install
mdr add puffo-ai/puffo-agent/manage-puffo-env-vars@sha256:c815bfa40c877bfcThe line at the top of this page pins the label git:20260811.0d9f44d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
