recall

recall is a skill for Claude Code from Mburdo/knowledge_and_vibes. It costs 55 tokens per session (1,948 once invoked), scanned A, original, MIT.

A guide for retrieving useful context from earlier coding-agent sessions, including remembered rules, previous solutions, and known mistakes.

In plain words
What is it for?
Use it before substantial implementation, when investigating how something was done before, or when you are stuck and need session history.
Why use it?
It helps avoid repeating past problems and preserves patterns that may matter for the current task.

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

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 6d 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 — 362 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Recall — Session Memory

Retrieve relevant history, rules, and anti-patterns from past sessions. Direct execution.

Design rationale: This skill executes directly rather than spawning subagents because memory retrieval is a simple command sequence (~200 tokens), not substantial analytical work. Per Lita research: "Simple agents achieve 97% of complex system performance with 15x less code."

When This Applies

Signal Action
Starting non-trivial task Distilled context
"What do we know about X?" Distilled context
"How did we do this before?" Session search
Looking for patterns/anti-patterns Distilled context
Stuck on a problem Deep dive
User says "/recall" Full protocol

Default: Retrieve context before any non-trivial implementation.


Tool Reference

Commands

Command Purpose
cm context "task" --json Distilled rules + anti-patterns
cm doctor Health check
cass search "query" --robot Raw session search
cass view /path.jsonl --json View full session
cass expand /path -n LINE -C 3 --json Expand with context
cass timeline --today --json Today's sessions
cass index --full Rebuild index

Critical Rule

Always use --robot or --json. Never run bare cass.

Bare cass launches a TUI that will hang AI agents.


Execution Flow

Execute these steps directly. No subagents needed.

Step 1: Distilled Context (Always Start Here)

cm context "{task_description}" --json

Returns:

  • Rules — Distilled patterns from past sessions
  • Anti-patterns — What NOT to do (and why)
  • Suggested searches — Specific CASS queries for more detail
  • Historical context — Related past work

Example:

cm context "implement OAuth login" --json
cm context "add new database migration" --json
cm context "refactor the payment module" --json

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.

recall is a skill published in the GitHub repository Mburdo/knowledge_and_vibes (44 stars, last pushed 8mo ago), licensed MIT. It adds 55 tokens to every session and 1,948 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.
