agent-memory-atlas: Skill for Codex

.agents/skills/add-memory-system/SKILL.md

add-memory-system is a skill for Codex from neoneye/agent-memory-atlas. It costs 57 tokens per session (6,998 once invoked), scanned A, original, MIT.

A workflow for researching and documenting a new agent-memory repository in Agent Memory Atlas, including its code, comparison pages, homepage, and generated site.

In plain words
What is it for?
Use it to add, analyze, catalogue, or compare a memory system, with repository screening and validation as part of the process.
Why use it?
It helps keep the catalogue's analysis grounded in a specific repository version while screening for execution and supply-chain risks.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: installed under .agents/ (shared by several agents).

This is neoneye/agent-memory-atlas's own configuration. It tells Codex how to work on agent-memory-atlas itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything agent-memory-atlas configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python3 scripts/screen_repo.py /absolute/path/to/source-repository.

Reuse

Borrowing it

Nothing to install: this file belongs to neoneye/agent-memory-atlas. Take a copy, put it at the same path in your own repository, and replace the rules that are about this project with yours.

Copy the file
curl -O https://raw.githubusercontent.com/neoneye/agent-memory-atlas/main/.agents/skills/add-memory-system/SKILL.md
Clone the repo
git clone --depth 1 https://github.com/neoneye/agent-memory-atlas

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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

add-memory-system 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 3d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/scaffold_report.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 395 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Add Memory System

Add one memory system to the atlas as a code-grounded, commit-pinned analysis. Treat the individual report, comparative synthesis, homepage, and generated site as one change.

Screen the checkout first — this is a precondition, not a suggestion. Run the screen-repository skill before reading a single file of a newly cloned tree:

python3 scripts/screen_repo.py /absolute/path/to/source-repository

Analysis means cloning a stranger's repository onto a personal machine and often running its build or its tests. Auto-executing hooks fire without a command being typed, and an unpinned dependency is a supply-chain compromise waiting on somebody else's account. Read every RUNS finding before doing anything else, keep the default posture read-only, and prefer npm ci --ignore-scripts and a throwaway venv over the documented install when execution is genuinely needed. NOTHING SCANNED is a finding, not a pass, and so is FRESHnever install a third-party dependency published in the last seven days, because that window is where an undetected registry compromise lives. npm ci does not protect you there: it reproduces the lockfile faithfully however new the pin is. Record the outcome in the report's History entry.

If the atlas already has a report for this repository, this is the wrong skill — use reanalyze-memory-system, which covers re-pinning, deciding whether a published claim went stale, and the rename-and-redirect convention. Check first:

rg -l '^source_url:.*<owner>/<repo>' content/systems/

A renamed upstream will not match on name; search the pinned revision as well before concluding it is new.

Establish the inputs

Resolve these before writing:

  • The Agent Memory Atlas repository root.
  • A local checkout of the memory-system repository.
  • A unique lowercase filename slug.
  • The canonical source repository URL.
  • The exact full commit ID being analyzed.

Prefer a local checkout because the report must trace implementation paths. Do not change the source repository. If only a URL is available, clone it to a temporary directory when network access and user authorization allow it.

What ships with it

2 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.

It adds 57 tokens to every session and 6,998 once invoked, about $0.0003 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.
