What it does
Drift Detection is an agent skill from bolivian-peru/os-moda. Detect configuration drift — manual changes that exist outside NixOS management. Offer to bring imperative changes into declarative config.
Its SKILL.md is about 580 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in DevOps & Cloud, covering GitOps. The repository describes itself as: An operating system built for AI agents — talk to your NixOS server instead of SSH-ing in. Typed, audited tool access with atomic rollback on every change. Research-grade; run it… The licence is Apache-2.0.
When your agent uses it
- Tasks that involve GitOps
Example prompts
- “/drift-detection”
Workflow steps
5 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit b8e418f. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Drift Detection loads about 584 tokens when it runs. Until then it costs about 39 tokens; SKILL.md has 169 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Configuration Drift Detection
NixOS is declarative — the config should be the single source of truth. But reality drifts: manual edits, imperative installs, ad-hoc cron jobs. Detect and reconcile.
Checks
1. Imperatively installed packages
shell_exec({ command: "nix-env -q 2>/dev/null || echo 'none'" })If packages found: offer to add them to environment.systemPackages in NixOS config.
2. Manual files outside NixOS
shell_exec({ command: "find /etc -newer /etc/NIXOS -not -path '/etc/nixos/*' -not -path '/etc/resolv.conf' -type f 2>/dev/null | head -20" })Files modified after last NixOS rebuild may be manual edits.
3. Manual cron jobs
shell_exec({ command: "ls /etc/cron.d/ /var/spool/cron/crontabs/ 2>/dev/null" })Offer to convert to systemd timers in NixOS config.
4. Stale NixOS generations
shell_exec({ command: "nixos-rebuild list-generations 2>/dev/null | wc -l" })More than 20 generations → suggest cleanup.
5. Orphaned systemd units
shell_exec({ command: "systemctl list-units --state=failed --no-pager" })Remediation
For each drift finding, offer to bring it into NixOS:
Drift Report:
⚠️ 3 packages installed via nix-env: htop, ncdu, tree
→ Add to environment.systemPackages? [Y/n]
⚠️ /etc/cron.d/backup exists outside NixOS
→ Convert to systemd timer in NixOS config? [Y/n]
⚠️ 47 old NixOS generations (using 18GB)
→ Keep current + last 5, remove rest? [Y/n]
✅ No unauthorized file changes in /etc/nixos/
✅ All systemd services match NixOS configWhy This Matters
On Ubuntu, configuration drift is invisible and irreversible. On NixOS with osModa, you can:
- Detect that something was changed manually
- Reconcile by adding it to the declarative config
- Prove with the audit ledger that nothing unauthorized happened
- Reproduce the exact system state on new hardware
This is useful supporting evidence for compliance programs (SOC 2, etc.) — though not by itself proof of regulatory readiness.

Can I use Drift Detection in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add bolivian-peru/os-moda --skill drift-detection -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/drift-detection, .gemini/skills/drift-detection, .github/skills/drift-detection and .opencode/skills/drift-detection in your project.
What does Drift Detection need to run?
SKILL.md names no scripts, command-line tools or credentials: Drift Detection is instructions for the agent only.
Does Drift Detection access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Drift Detection safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Drift Detection use?
Drift Detection is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Drift Detection use?
About 584 tokens (SKILL.md is roughly 2.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
