notes

notes is a skill for Claude Code, Codex from anthonysuherli/br8n. It costs 86 tokens per session (853 once invoked), scanned A, original, MIT.

A repository-specific policy editor for the notes br8n records after each coding session. It lets you view the note structure and instructions, change them, or set them through a guided wizard.

In plain words
What is it for?
Use it to view or change the sections and guidance used for end-of-session notes for the current repository and branch.
Why use it?
It helps ensure future session notes capture the information your team cares about, such as architecture decisions, while leaving out less useful details.

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

notes 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 4d 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.

br8n — Notes (steer the session-note policy)

br8n writes a session note at the end of every conversation (see ../_shared/session-note.md — fired by the Stop hook, best-effort, never blocking). What goes into that note is governed by a per-KB policy: a section template (## Decisions, ## Changes, …) plus a free-text steer ("emphasize architecture, skip dependency bumps"). This skill is how you read and shape that policy. It does not write a note itself — it only changes the rules the next session note follows.

Step 0 — Resolve target

project = git repo basename, kb = git branch, project_path = repo root (see ../_shared/preamble-first.md):

basename "$(git rev-parse --show-toplevel)"   # project
git branch --show-current                     # kb
git rev-parse --show-toplevel                 # project_path

No prior tap needed — policy read/write is independent of KB coverage.

Mode select — branch on the args

Invocation Mode Do
/br8n:notes (no args) Show Step A — print the current policy
/br8n:notes <free text> Steer Step B — set the steer to that text
/br8n:notes --wizard Wizard Step C — run the guided co-design

Step A — Show the current policy

Call mcp__plugin_br8n_br8n__br8n_notes_policy_get(project, kb, project_path). It returns {policy: {sections: [{name, enabled}], steer}, project, kb} (the default policy if none is set yet). Render it readably:

Note policy<project> / <kb> Sections the next note will use:

  • <name> — enabled / disabled Steer: <steer, or "(none)">

Then mention the two ways to change it: pass free text to set a steer, or --wizard to redesign the section template.

Step B — Set the steer from free text

The args are the new steer (e.g. /br8n:notes focus on architecture, skip dep bumps).

  1. br8n_notes_policy_get(project, kb, project_path) — fetch the current policy.
  2. Keep its sections exactly as-is; replace steer with the user's text.
  3. mcp__plugin_br8n_br8n__br8n_notes_policy_set(project, kb, project_path, policy=<updated>). On {ok: false, errors} show the errors, fix, and retry — nothing is saved until valid. On {ok: true} confirm: echo the new steer and the (unchanged) section list so the user sees exactly what the next session note will honor.

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.

notes is a skill published in the GitHub repository anthonysuherli/br8n (1 stars, last pushed 1mo ago), licensed MIT. It adds 86 tokens to every session and 853 once invoked, about $0.0004 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 2026-08-31.
