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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Excessive Agency · line 8 Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.
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 | $0.00054 | $0.00849 |
| Opus 5 | $0.00027 | $0.00425 |
| Sonnet 5 | $0.00011 | $0.00170 |
| Haiku 4.5 | $0.00005 | $0.00085 |
Grade A, and why
experiment 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 8d 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 — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Experiment
Act → sense → gate. Human IS the constraint. No autonomous runs.
Situation: $ARGUMENTS
⚠️ AskUserQuestion Guard
CRITICAL: After EVERY AskUserQuestion call, check if answers are empty/blank. Known Claude Code bug: outside Plan Mode, AskUserQuestion silently returns empty answers without showing UI.
If answers are empty: DO NOT proceed with assumptions. Instead:
- Output: "⚠️ Questions didn't display (known Claude Code bug outside Plan Mode)."
- Present the options as a numbered text list and ask user to reply with their choice number.
- WAIT for user reply before continuing.
0. Classify Chaos
AskUserQuestion — single call:
"Accidental or deliberate?"
- Accidental (crisis): something broke badly — production down, data corruption, cascading failure → faster gates
- Deliberate (innovation): intentional disruption — novel architecture, paradigm shift, no prior art → exploratory gates
Set mode = accidental|deliberate.
1. Frame the Void
State what is NOT known (not what is known):
- No visible cause-effect relationships
- No best practice applies
- No expert can say "do X"
Identify: what is the minimal safe action to impose ANY constraint on this space?
2. Act-Gate Loop
Repeat until structure emerges or transition triggered:
Act
- Propose ONE minimal action (smallest possible intervention)
- State expected signal: "if this works, we'll see X"
isolation: worktreefor containment if code changes involved
Gate
AskUserQuestion: "Ready to act? Describe outcome after: [action]"
Wait for human response. Gate fires after EVERY action — no batching.
Sense
Interpret the response:
- Signal received → update constraint map
- No signal → action was too small or wrong dimension
- Negative signal → constraint hardened in wrong direction
Log: action N: [what] → [outcome] → [constraint discovered]
3. Structure Check
After each gate, assess:
Constraint type now:
- Still absent → continue act-gate loop
- Enabling (patterns visible) → TRANSITION to /probe
- Governing (experts applicable) → skip /probe → /frame-problem → /investigate
- Rigid (process known) → skip /probe → /frame-problem → execute
- Misclassified → TRANSITION to /frame-problem
What ships with it
3 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.
- 8d ago First seen · 102 lines · 54 tokens per session scan A 3bafe501168b
experiment is a skill published in the GitHub repository digital-stoic-org/agent-skills (20 stars, last pushed 2d ago), licensed MIT. It adds 54 tokens to every session and 849 once invoked, about $0.0003 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.
