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.
