Apply the user-customizable writing standard for Basic Memory notes created or substantially revised by Codex.

What it does

Bm Writing is an agent skill from basicmachines-co/basic-memory. Apply the user-customizable writing standard for Basic Memory notes created or substantially revised by Codex. Use with bm-checkpoint, bm-decide, bm-remember, and other Basic Memory note-writing workflows.

Its SKILL.md is about 830 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including assets (for example `agents/openai.yaml`).

It sits in Writing & Content, covering Plain language and style rules. The repository describes itself as: AI conversations that actually remember. Never re-explain your project to your AI again. Join our Discord: https://discord.gg/tyvKNccgqN. The licence is AGPL-3.0.

When your agent uses it

  • Tasks that involve Plain language and style rules

Example prompts

  • “/bm-writing”

What it can do on your machine

Read from SKILL.md and the folder at commit 6982cfc. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Bm Writing loads about 826 tokens when it runs. Until then it costs about 54 tokens; SKILL.md has 449 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~54
When it runs · the whole SKILL.md, loaded when a task matches
~826

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Write Useful Project Memory

Use this shared standard whenever a Codex Basic Memory skill writes or substantially revises a note. This file is intentionally user-customizable: edit the voice, emphasis, and preferred structure here to fit how you want to remember your work.

Task-specific skills still own required metadata, schemas, evidence gathering, and workflow. This skill shapes the note; it never overrides factual constraints.

Voice

  • Write for a human or agent returning later and trying to understand what happened.
  • Be clear, direct, warm, and technically honest.
  • Prefer concrete observations over generic praise.
  • Have a point of view when the evidence supports it. It is fine to call a change elegant, messy, risky, boring, or satisfying when you explain why.
  • Keep personality in service of memory, not performance.

Tell The Story

  • Give the note a narrative spine: problem -> approach -> current state and impact.
  • Explain why the approach works, how the system or workflow changed, and why that difference matters.
  • Name relevant tradeoffs, sharp edges, useful simplifications, removals, and intentionally parked work.
  • Prefer exact behavior, component names, paths, and commands over phrases such as "made progress" or "updated the implementation."
  • Use substantive prose for context and reasoning. Do not reduce the note to a wall of bullets or a commit-by-commit changelog.
  • Name the durable lesson when one exists — the constraint discovered, the boundary made explicit, the shortcut future work should avoid. That is the part that turns a status report into project memory.
  • Match depth to the subject. A small remembered fact should remain small.

Anchor The Work

  • When the note records repository work, capture where that work lives: the project or repo, the git branch, and the PR or issue — plus the commit sha when a specific commit matters.
  • Put anchors the note's schema defines in frontmatter; record the rest as observations, e.g. - [branch] feat/bm-writing or - [pr] #1123.
  • Render GitHub-backed PR, issue, and commit anchors as Markdown links when their canonical URLs are verified. Keep local or unpushed SHAs as code instead of constructing links that may not exist.
  • Only anchor what is relevant. A remembered fact with no repo context needs no git anchors at all.

Preserve The Semantic Layer

  • Distill durable facts under ## Observations as - [category] fact.
  • Record decisions as [decision] observations, not plain bullets in a separate Decisions section.
  • Put graph edges under ## Relations using - relation_type [[Target Note]]. Never represent a relation as an observation such as [relates_to].
  • Add relations when they clarify context; do not manufacture targets merely to make a note look connected.

Evidence Boundary

  • Do not invent intent, impact, verification, decisions, or drama.
  • State uncertainty and missing evidence plainly.
  • Never claim a test or deployment passed unless it ran or the user supplied the result.
