role-memory

role-memory is a skill for Claude Code, Codex from Jarroslav/agentic-os. It costs 159 tokens per session (1,825 once invoked), scanned A, original, Apache-2.0.

A persistent memory system for agents, stored as plain Markdown files under .agents/memory. It keeps durable facts and preferences separately from an append-only daily activity log, with one memory area per agent role.

In plain words
What is it for?
Use it when someone asks the agent to remember or log something, asks what it learned previously, or when a durable project constraint or preference should be recorded for later sessions.
Why use it?
It prevents useful project decisions and observations from being lost when a conversation or context window ends.

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

role-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 4d 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 — 179 lines — stays where its author put it; the contents beside it link to each section on GitHub.

role-memory

Give the agent a memory that survives context resets. Each role owns a directory of plain markdown you manipulate directly with your file tools. No wrapper binary, no shell-path dependence — the layout is identical on every host.

Two stores, two costs. The daily log is cheap and episodic: one appended line per observation, no promise of lasting value. A curated entry is durable — a fact expected to stay useful for roughly six months — and costs one index slot. Spend the expensive store deliberately.

When to use

  • User says "remember this", "log this", or asks "what did you learn yesterday".
  • You learn something durable — a preference, a validated correction, a project constraint, a pointer to an external system — that a future session would waste effort rediscovering.
  • You are about to act and need to recall what this role already knows.

Role identity

The role is the agent's own name: frontmatter value (e.g. project-manager, python-dev, scout). Every fact below scopes to <role>; each role gets its own directory. Never read or write another role's memory.

Layout (fixed contract)

.agents/memory/<role>/ contains:

Path What it is
MEMORY.md The curated index — one line per entry.
<slug>.md One curated entry (durable fact/preference/decision/pointer).
project_briefing.md The scout-seeded project entry (stack, conventions, role pitfalls).
daily/YYYY-MM-DD.md One episodic log file per day.
snapshot.md Supervisor-generated digest — you never write this.

.agents/ is chosen as an IDE-neutral root so the tree is the same across hosts. Create directories lazily with mkdir -p on first use. You may add role-specific operational files to the directory (for example a personal-assistant's people-pending.md) as long as the core files above keep their formats.

Curated entry format

Exactly three frontmatter keys, no extras, one per line — the supervisor's snapshot regenerator parses these:

Files

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.
