brainmaxxing: Skill for Claude Code

.agents/skills/reflect/SKILL.md

reflect is a skill for Claude Code, Codex from poteto/brainmaxxing. It costs 40 tokens per session (514 once invoked), scanned A, original, MIT.

A reflection workflow for reviewing a conversation and saving useful lessons about mistakes, preferences, code, tools, or decisions. The saved notes can go into a shared “brain” or into rules and skills.

In plain words
What is it for?
It is for wrapping up work, recording corrections and codebase discoveries, and updating the agent’s persistent notes or instructions.
Why use it?
It helps preserve knowledge that would otherwise be lost after the conversation, while encouraging repeatable lessons to become automated checks when possible.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is poteto/brainmaxxing's own configuration. It tells Claude Code and Codex how to work on brainmaxxing 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 brainmaxxing 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

reflect 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 1mo 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.

Reflect

Review the conversation and persist learnings — to brain/, to skill files, or as structural enforcement.

Process

  1. Read brain/index.md to understand what notes already exist
  2. Scan the conversation for:
    • Mistakes made and corrections received
    • User preferences and workflow patterns
    • Codebase knowledge gained (architecture, gotchas, patterns)
    • Tool/library quirks discovered
    • Decisions made and their rationale
    • Friction in skill execution, orchestration, or delegation
    • Repeated manual steps that could be automated or encoded
  3. Skip anything trivial or already captured in existing brain files
  4. Route each learning to the right destination (see Routing below)
  5. Update brain/index.md if any brain files were added or removed

Routing

Not everything belongs in the brain. Route each learning to where it will have the most impact.

Structural enforcement check

Before routing a learning to brain/, ask: can this be a lint rule, script, metadata flag, or runtime check? If yes, encode it structurally and skip the brain note. See brain/principles/encode-lessons-in-structure.md.

Brain files (brain/)

Codebase knowledge, principles, gotchas — anything that informs future sessions. This is the default destination. Use the brain skill for writing conventions.

  • One topic per file. File name = topic slug.
  • Group in directories with index files using [[wikilinks]].
  • No inlined content in index files.

Skill improvements (.agents/skills/<skill>/)

If a learning is about how a specific skill works — its process, prompts, or edge cases — update the skill directly.

Backlog items

Follow-up work that can't be done during reflection — bugs, non-trivial rewrites, tooling gaps. File as a todo or backlog item.

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.

reflect is a skill published in the GitHub repository poteto/brainmaxxing (342 stars, last pushed 7mo ago), licensed MIT. It adds 40 tokens to every session and 514 once invoked, about $0.0002 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.
