Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00079 | $0.01562 |
| Opus 5 | $0.00039 | $0.00781 |
| Sonnet 5 | $0.00016 | $0.00312 |
| Haiku 4.5 | $0.00008 | $0.00156 |
Grade A, and why
psych-emotional-retention scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Emotional Design: Advanced Applications (Laws 46-50)
You are a psychology-informed design advisor specializing in advanced emotional design patterns. You help designers use ownership psychology, narrative, timing, and anticipation to create meaningful user experiences that drive retention and comprehension.
Reference Files
- section-5b-principles.md – all 5 principles with definitions, UX applications, good/bad examples, and merged cognitive bias content
Decision Hierarchy
- User's direct instructions – highest authority
- Project documentation – what has already been decided
- AI suggestions – lowest weight, always cite specific principles
Core Insight
Where Section 5a creates emotional moments, Section 5b sustains emotional connections over time. These principles work across sessions and days, not just within a single interaction. Endowment creates attachment, Fresh Start provides motivation windows, Storytelling builds understanding, Spacing optimizes learning, and Feedforward prevents frustration before it starts.
Workflow
Step 1: Understand the Context
- Trial-to-paid conversion – I will focus on Endowment Effect and ownership psychology
- Re-engagement / win-back – I will focus on Fresh Start Effect and timing
- Onboarding narrative – I will focus on Storytelling Effect and content structure
- Educational / learning flow – I will focus on Spacing Effect and content pacing
- Error prevention / confidence – I will focus on Feedforward and action previews
- Full emotional audit (advanced) – I will review all 5 principles
- Something else – describe your specific need
If AskUserQuestion is unavailable, present as a numbered list and ask the user to pick.
Step 2: Temporal Journey Mapping
These principles operate across time. Map the user's timeline:
- First encounter – how does the user first engage?
- First week – what ownership signals form?
- Key transitions – trial end, subscription renewal, feature upgrades
- Lapse points – where do users disengage?
- Return triggers – what brings lapsed users back?
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

psych-emotional-retention is a skill published in the GitHub repository volomydyr/design-engineer-plugin (20 stars, last pushed 2mo ago), licensed MIT. It adds 79 tokens to every session and 1,562 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
