cf-remember

cf-remember is a skill for Claude Code, Codex from dinhanhthi/coding-friend. It costs 109 tokens per session (2,562 once invoked), scanned A, original, MIT.

A project-memory tool that writes important coding knowledge into documentation files for later recall.

In plain words
What is it for?
Use it to record architecture decisions, coding conventions, non-obvious bug fixes, and notes about how the project works.
Why use it?
It prevents decisions, conventions, bug explanations, and other useful context from being lost between coding sessions.

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

cf-remember 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 5d 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.

How it starts

The opening of the file, as written. The whole thing — 233 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/cf-remember

CLI Requirement: OPTIONAL — Uses the memory MCP from coding-friend-cli for fast indexed search and storage. Without the CLI: falls back to grep over docs/memory/ and direct file writes. Full functionality preserved, slower memory recall. See CLI requirements.

Extract and save project knowledge. User input: $ARGUMENTS

Purpose

After a coding session, key knowledge gets lost — logic flows, conventions, decisions, gotchas. This skill captures that knowledge into the project's memory folder so future sessions (and humans) can quickly understand the project.

Folder

Output goes to {docsDir}/memory/ (default: docs/memory/). Check .coding-friend/config.json for custom docsDir if it exists.

IMPORTANT — path resolution:

  • Use MAIN_REPO_ROOT from the SessionStart bootstrap context (injected via session-init.sh). If absent, fall back to running pwd for $CWD and use $CWD as MAIN_REPO_ROOT.
  • Read config from CF_CONFIG_FILE (= $MAIN_REPO_ROOT/.coding-friend/config.json) — do NOT search sub-folders
  • Use CF_DOCS_ROOT as the docs base dir (= $MAIN_REPO_ROOT/{docsDir} where docsDir comes from config, default docs)
  • Always resolve file_path as an absolute path: {CF_DOCS_ROOT}/memory/{category}/{name}.md
  • Never use relative paths in write specs — they may resolve incorrectly when the working directory contains nested git repos

Workflow

Step 0: Custom Guide

Custom guide — auto-loaded below (if the raw command shows instead of its output, run it yourself):

bash "<plugin-root>/lib/load-custom-guide.sh" cf-remember

If output is not empty, integrate returned sections: ## Before → before first step, ## Rules → apply throughout, ## After → after final step.

Step 1: Analyze the Conversation

If $ARGUMENTS is provided, use it as a filter — focus only on conversation content that relates to the user's stated purpose. Otherwise, scan the full conversation.

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.

cf-remember is a skill published in the GitHub repository dinhanhthi/coding-friend (3 stars, last pushed today), licensed MIT. It adds 109 tokens to every session and 2,562 once invoked, about $0.0005 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.
