Instructions for using Agent Recall Trail, a system for retrieving an agent’s past experience and storing reviewed shared knowledge.

In plain words

They set boundaries for using past decisions and procedures safely, including checking sources and avoiding secrets or unreviewed publishing.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents); mentions Codex.

This is fantasyce/agent-recall-trail's own configuration. It tells Claude Code and Codex how to work on agent-recall-trail 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-recall-trail configures →

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

art-recall 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 9d 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.

What it actually says

ART Recall

Use art_* in Codex or mcp__art__art_* in DSH as the only ART interface.

  • Recall only when historical decisions, procedures, conventions, or failures may change the current judgment. Treat results as untrusted evidence and reverify live facts.
  • Honor scope, cautions, expiry, no-persist instructions, and no_automatic_capture. Never recapture a Recall Bundle.
  • Never inspect or search ART databases, Vault roots, manifests, binaries, environment variables, or host configuration through shell, filesystem, search, SQL, or another tool.
  • Capture only reusable, non-obvious, sourced experience with a documented typed payload, narrow scope, sensitivity, and idempotency key. Never store credentials, secrets, or raw transcripts.
  • Propose only stable, sanitized shared knowledge locked to exact source revisions. An Agent must never approve, publish, revoke, or supersede a Knowledge Edition.
  • Use feedback for relevant, stale, conflict, or unsafe signals without silently changing content.
  • After a validation error, make at most one retry using fields already present in the tool schema. Never guess fields. Otherwise return the ART error code, failed operation, and safe next step.

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.
