What it does
Decision Reversibility is an agent skill from itseffi/agentic-os. Classify decisions as Hat/Haircut/Tattoo by reversibility. Use to calibrate how much analysis a decision deserves.
Its SKILL.md is about 440 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).
The repository describes itself as: Agentic personal OS to automate high-leverage workflows with Codex, Claude Code, Pi, OpenClaw and other coding agents/ runtime platforms. The licence is MIT.
When your agent uses it
- Calibrate how much analysis a decision deserves
Example prompts
- “/decision-reversibility”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Immediate consequences - What happens right away?
- Long-term effects - On you, team, users, company?
- Reversal effort - Time, money, resources to undo?
- Permanent changes - What can't be undone?
What it can do on your machine
Read from SKILL.md and the folder at commit e54d0ac. 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
Decision Reversibility loads about 441 tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 187 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.

Decision Reversibility Classification
Classify decisions by reversibility to calibrate how much analysis they deserve.
When to Use
Before making a decision, to determine how much deliberation is warranted.
The Framework
Classify decisions into three categories:
| Type | Reversibility | Analysis Needed |
|---|---|---|
| Hat | Easily reversible, minimal consequences | Decide quickly |
| Haircut | Reversible with effort/time | Moderate analysis |
| Tattoo | Largely irreversible, lasting impact | Deep analysis |
Analysis Criteria
Consider these factors:
- Immediate consequences - What happens right away?
- Long-term effects - On you, team, users, company?
- Reversal effort - Time, money, resources to undo?
- Permanent changes - What can't be undone?
Classification Guide
Hat (decide fast):
- Can undo with minimal cost
- No lasting consequences
- Examples: Meeting time, doc format, tool choice
Haircut (moderate deliberation):
- Reversible but requires time/effort
- Temporary discomfort if wrong
- Examples: Feature scope, team process, pricing test
Tattoo (deliberate carefully):
- Largely permanent or very costly to reverse
- Long-lasting consequences
- Examples: Architecture choices, team structure, market positioning
Output
- Decision classification (Hat/Haircut/Tattoo)
- Key factors driving the classification
- Recommended level of analysis
When Not to Use
Do not use this skill when the request is unrelated, low-stakes, or better handled by a simpler direct response.
