What it does
Eol Checklist is an agent skill from deanpeters/Product-Manager-Skills. Build a phase-gated EOL checklist sized to the sunset, with a named owner on every item. Use when the decision to retire is made and you need the operational plan.
Its SKILL.md is about 3.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files (for example `examples/sample-industrial.md`, `examples/sample.md` and `template.md`).
The repository describes itself as: Product Management skills framework built on battle-tested methods for Claude Code, Cowork, Codex, and AI agents.
When your agent uses it
- The decision to retire is made and you need the operational plan
Example prompts
- “/eol-checklist”
Workflow steps
5 steps, taken from the step headings in SKILL.md.
- Set the level
- Select phases in scope
- Build items per phase, per area
- Write gate criteria (Level 2+)
- Post-EOL actions and assumptions
What it can do on your machine
Read from SKILL.md and the folder at commit 1b5a524. 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
Hosts in commands or code, which the agent is likely to contact:
github.com
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
Eol Checklist loads about 3.2k tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 1,672 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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,672 words (~3,151 tokens).
