What it does

Product Lifecycle Plays is an agent skill from deanpeters/Product-Manager-Skills. Map a product's lifecycle stage and choose between extension, replacement, and retirement plays. Use when a product is maturing or declining and the next move isn't obvious.

Its SKILL.md is about 4.2k 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

  • A product is maturing
  • Declining and the next move isnt obvious

Example prompts

  • “/product-lifecycle-plays”

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Diagnose the stage
  2. Identify what's driving the pressure
  3. Test the extension play first
  4. If replacing, build the risk register before committing
  5. If retiring, hand off
  6. Run it across the line

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

    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

Product Lifecycle Plays loads about 4.2k tokens when it runs. Until then it costs about 49 tokens; SKILL.md has 2,200 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~49
When it runs · the whole SKILL.md, loaded when a task matches
~4.2k

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 2,200 words (~4,214 tokens).

“Decide what to do with a product that has stopped growing. There are three plays — extend, replace, retire — and picking the wrong one is expensive in a different way each time. This skill gives you the stage diagnosis…”
