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.

What it costs to keep this loaded
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 | $0.00104 | $0.02196 |
| Opus 5 | $0.00052 | $0.01098 |
| Sonnet 5 | $0.00021 | $0.00439 |
| Haiku 4.5 | $0.00010 | $0.00220 |
Grade A, and why
s4h-psychology-behavior-change 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 9d 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.
How it starts
The opening of the file, as written. The whole thing — 144 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Psychology: Behavior Change
Behavior is not driven primarily by intention. A person can fully intend to exercise, stop checking their phone, or give direct feedback — and consistently fail to do so. The intention-behavior gap is real and large. It exists because behavior is maintained by systems: habit loops, environmental cues, identity commitments, friction levels, and social norms. Changing behavior requires diagnosing which of these systems is doing the work, then intervening at the right level. Motivational exhortation without system change produces guilt, not results.
Your Process
Step 1: Specify the Behavior Be precise. Not "be healthier" but "go for a 30-minute walk after work on weekdays." Not "be a better communicator" but "give direct negative feedback in the weekly 1:1 rather than softening it into ambiguity." Vague behavior targets produce vague interventions.
Also specify: are you trying to stop a behavior, start a behavior, or modify (frequency, intensity, consistency) a behavior? These have different intervention profiles.
Framing check: Confirm the specific behavior before continuing. State what you've identified — the exact behavior and whether the goal is to start, stop, or modify it — in one sentence, then use AskUserQuestion:
- Question: "I'm reading this as: [your one-sentence framing of the specific behavior and direction]. Is that right?"
- Header: "Framing"
- Options:
- Yes — proceed — framing is correct
- Adjust — one element is off; user will correct it before you continue
- Reframe — different situation than read; incorporate the correction before proceeding
Step 2: Diagnose What's Maintaining the Current Behavior Most behavioral persistence has a cause. Identify which mechanism is doing the work:
Habit loop (Cue → Routine → Reward): Is the behavior automatic — triggered by a cue without deliberate decision? If yes, the habit loop is the primary mechanism. The cue activates the routine; the routine delivers a reward (often neurological, often faster than the negative consequence). To change it: identify the cue, design a competing routine that delivers the same (or better) reward, and repeat until the new loop is automatic.
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.

s4h-psychology-behavior-change is a skill published in the GitHub repository human-avatar/skills-for-humanity (223 stars, last pushed 1mo ago), licensed MIT. It adds 104 tokens to every session and 2,196 once invoked, about $0.0005 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 2026-09-03.
