What it does
Retention Loop Design is an agent skill from mohitagw15856/pm-claude-skills. Design retention and engagement loops that bring users back. Use when asked to improve retention, design an engagement/habit loop, fix a leaky retention curve, or build a re-engagement system. Produces a retention design — the retention curve diagnosis, the core habit loop (trigger→action→reward→investment), the activation→habit path, re-engagement triggers, and the metrics to watch.
Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: 1255 professional Agent Skills for Claude, ChatGPT, Gemini, Cursor & Codex — PRDs, postmortems, leases, medical bills, layoffs, go-bags, new countries. Plain markdown, MIT, in… The licence is MIT.
When your agent uses it

- Design an engagement/habit loop
- Fix a leaky retention curve

What it can do on your machine
Read from SKILL.md and the folder at commit 1cbf1f0. 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
Retention Loop Design loads about 1k tokens when it runs. Until then it costs about 102 tokens; SKILL.md has 509 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.

- retention-loop-design
- description
- Design retention and engagement loops that bring users back. Use when asked to improve retention, design an engagement/habit loop, fix a leaky retention curve, or build a re-engagement system. Produces a retention design — the retention curve diagnosis, the core habit loop (trigger→action→reward→investment), the activation→habit path, re-engagement triggers, and the metrics to watch.
Retention Loop Design Skill
Acquisition without retention is a leaky bucket — you pay to fill it and it drains. This skill diagnoses where and why users drop, then designs the loop that makes the product habitual: the trigger that brings them back, the value they get, and the investment that makes the next visit more likely. Retention is the truest measure of product-market fit.
Required Inputs
Ask for these only if they aren't already provided:
- The retention curve — how usage decays over time (D1/D7/D30, or weekly cohorts); does it flatten or go to zero?
- The core value & natural frequency — what users come for, and how often they'd genuinely need it.
- Activation definition — the early action that correlates with sticking (or note it's unknown).
- Current loops — any notifications, streaks, or re-engagement already in place.
Output Format
Retention Design: [product]
1. Curve diagnosis — read the retention curve: does it flatten (a retained core exists — good) or decay to zero (no PMF for this segment)? Identify the drop-off point and the cohort that retains best (your beachhead).
2. Activation → habit — the early "setup moment" and the habit milestone (e.g. "3 sessions in week 1"); the shortest path to it, since activation is the strongest lever on long-term retention.
3. The core loop — design the engagement loop explicitly:
- Trigger — external (notification, email) and the internal trigger you want to own (the felt need).
- Action — the simplest behaviour that delivers value.
- Reward — the value/variable reward received.
- Investment — what the user puts in (data, content, social, configuration) that makes the next loop better and raises switching cost.
4. Natural frequency match — align the loop's cadence to how often the job actually recurs; don't manufacture engagement the product doesn't warrant.
5. Re-engagement — triggered winback for users sliding toward churn (behavioural signal → message → return path); pair with lifecycle-crm-plan.
6. Metrics — the retention metric and cohort view to watch, plus the leading indicator (habit-milestone rate) that predicts it.

Quality Checks
- The retention curve is diagnosed as flattening vs. decaying — that determines whether to fix retention or fix fit first
- Activation/habit milestone is defined and tied to long-term retention
- The loop names a trigger, action, reward, AND investment (the investment is what compounds)
- Loop cadence matches the product's natural frequency — no manufactured engagement
- A leading indicator (not just lagging retention) is identified to act on early
Anti-Patterns
- Do not optimise retention before the curve flattens for some segment — if it decays to zero there's no PMF to retain, fix that first
- Do not bolt on streaks/badges without a real reward — gamification on a product with no core value just annoys
- Do not spam notifications to force engagement — manufactured frequency drives uninstalls and erodes trust
- Do not ignore the investment phase — without stored value/data, there's nothing raising the cost of leaving
- Do not report only average retention — cohorts and the best-retaining segment tell you where to aim
Based On
The Hook Model (Nir Eyal) and cohort-retention analysis practice (flattening curve = PMF signal).
Example Trigger Phrases
- "Improve retention."
- "Design an engagement/habit loop."
- "Fix a leaky retention curve."
- "Build a re-engagement system."
