What it does
Pestel Delta Monitor is an agent skill from deanpeters/Product-Manager-Skills. Quarterly re-scan of a prior PESTEL analysis. Use when checking which macro factors moved, which assumptions broke, and what's new — turning PESTEL from a workshop artifact into a radar.
Its SKILL.md is about 2.5k 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`).
It sits in Business, Finance & HR, covering Startup and business strategy. 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
- Checking which macro factors moved
- Which assumptions broke
- Whats new — turning PESTEL from a workshop artifact into a radar
Example prompts
- “/pestel-delta-monitor”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Check the prerequisite. No prior PESTEL → recommend pestel-analysis
- Credit inline context, then ask only the unanswered questions (max 2)
- Read the prior analysis fully; diff factor by factor — the baseline document is the diff
- Show the 3-bullet search plan — which factor categories get active searching this cycle
- Emit the schema below exactly.
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 (its code samples are markdown).
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
Pestel Delta Monitor loads about 2.5k tokens when it runs. Until then it costs about 52 tokens; SKILL.md has 971 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 971 words (~2,462 tokens).
“Refresh a PESTEL analysis by diffing each factor — Political, Economic, Social, Technological, Environmental, Legal — against the prior run and reporting material movement only: search plan → factor-by-factor diff → broken assumptions → new entrants to the frame →…”
