project-memory

project-memory is a skill for Claude Code, Codex from klh/speedy-claude. It costs 89 tokens per session (2,587 once invoked), scanned A, original, MIT.

A structured set of project notes that stores bugs and their solutions, architecture decisions, important facts, and work history. It can also configure project instruction files so coding agents consult and update this memory.

In plain words
What is it for?
Use it to start project memory, record decisions and fixes, track known issues, and preserve facts that future contributors or agents need.
Why use it?
It prevents useful knowledge from disappearing between coding sessions or getting lost when different AI tools work on the project.

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

project-memory 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 yesterday.

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.

Project Memory

Table of Contents

Overview

Maintain institutional knowledge for projects by establishing a structured memory system in docs/project_notes/. This skill sets up four key memory files (bugs, decisions, key facts, issues) and configures CLAUDE.md and AGENTS.md to automatically reference and maintain them. The result is a project that remembers past decisions, solutions to problems, and important configuration details across coding sessions and across different AI tools.

When to Use This Skill

Invoke this skill when:

  • Starting a new project that will accumulate knowledge over time
  • The project already has recurring bugs or decisions that should be documented
  • The user asks to "set up project memory" or "track our decisions"
  • The user wants to log a bug fix, architectural decision, or completed work
  • Encountering a problem that feels familiar ("didn't we solve this before?")
  • Before proposing an architectural change (check existing decisions first)
  • Working on projects with multiple developers or AI tools (Claude Code, Cursor, etc.)

Core Capabilities

6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

project-memory is a skill published in the GitHub repository klh/speedy-claude (11 stars, last pushed today), licensed MIT. It adds 89 tokens to every session and 2,587 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 2026-08-30.
