neuro-book: Skill for Claude Code

.agents/skills/task-reflection/SKILL.md

task-reflection is a skill for Claude Code, Codex from notnotype/neuro-book. It costs 41 tokens per session (1,226 once invoked), scanned A, original, AGPL-3.0.

A workflow for turning surprises, user corrections, and new rules from a task into proposed updates to the project's source of truth. The source of truth is the approved place where project guidance is kept.

In plain words
What is it for?
Use it after a task reveals a mistake or new requirement, or when a user asks for a review of what should be recorded for future work.
Why use it?
It helps keep reusable project guidance up to date without changing it automatically or without developer approval.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing. Also seen: installed under .agents/ (shared by several agents).

This is notnotype/neuro-book's own configuration. It tells Claude Code and Codex how to work on neuro-book itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything neuro-book configures →

Token cost

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.

Security

Grade A, and why

task-reflection 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 7d 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.

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.
