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 100 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
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 | $0.00093 | $0.01844 |
| Opus 5.5 | $0.00037 | $0.00738 |
| Sonnet 5.5 | $0.00019 | $0.00369 |
| Haiku 4.5 | $0.00009 | $0.00184 |
Grade A, and why
pstack 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 28d 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 — 109 lines — stays where its author put it; the contents beside it link to each section on GitHub.
pstack
Rigor over throughput. The point is to write less code, and to be able to prove the code you wrote works.
Original by Lauren Tan (poteto), MIT, from the Cursor plugin marketplace. This is a port: the principles and general skills are upstream's, the orchestration around them is rewritten for Claude Code and this repo. What changed and why: ATTRIBUTION.md.
How to use it
Read the principles below. Name the ones that shaped a decision, and say which choice each one changed. A citation with no decision behind it means you did not actually apply it — that is worse than not citing, because it reads as rigor without being rigor.
For any principle you actually apply, read its leaf skill in full
(skills/principle-<name>/SKILL.md). The one-liners here are an index, not
the content.
Principles
Core
- Laziness Protocol (
principle-laziness-protocol). Refactoring, sizing a diff, or tempted to add abstractions, layers, or signal threading. Bias to deletion and the smallest change that solves the problem. - Foundational Thinking (
principle-foundational-thinking). Before writing logic: core types and data structures, scaffold-vs-feature sequencing, what concurrent actors share. - Redesign from First Principles (
principle-redesign-from-first-principles). Integrating a new requirement into an existing design. Redesign as if it had been foundational from day one. - Subtract Before You Add (
principle-subtract-before-you-add). Sequencing an addition, refactor, or rewrite. Remove dead weight first, then build on the simpler base. - Minimize Reader Load (
principle-minimize-reader-load). Reviewing or shaping code that's hard to trace. Count layers and hidden state, collapse one-caller wrappers, shrink mutable scope. - Outcome-Oriented Execution (
principle-outcome-oriented-execution). Planned rewrites and migrations with explicit phase boundaries. Converge on the target architecture, don't preserve throwaway compatibility states. - Experience First (
principle-experience-first). Product, UX, or feature-scope tradeoffs. Choose user delight over implementation convenience. - Exhaust the Design Space (
principle-exhaust-the-design-space). A novel interaction or architectural decision with no precedent. Build 2-3 competing prototypes and compare before committing. - Build the Lever (
principle-build-the-lever). Any non-trivial work. Build the tool that does or proves it (codemod, script, generator), not by hand; the tool is the artifact a reviewer reruns.

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.

pstack is a skill published in the GitHub repository Sma1lboy/rove (178 stars, last pushed today), licensed MIT. It adds 93 tokens to every session and 1,844 once invoked, about $0.0004 per session on Opus 5.5. 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.
