squads-learn

squads-learn is a skill for Claude Code, Codex from agents-squads/squads-cli. It costs 41 tokens per session (609 once invoked), scanned A, original, MIT.

A procedure for recording useful lessons after software work, such as a completed feature, bug fix, research task, or discovered pattern. It stores the lesson with a short command and optional category, team, and tags.

In plain words
What is it for?
Use it after fixing bugs, completing features, researching a topic, or finding a reusable engineering pattern worth remembering.
Why use it?
It prevents important discoveries from being forgotten between tasks. It can build a shared record of what worked, what failed, and what to repeat.

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

squads-learn 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 1mo 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.

Capture Learnings

After completing work, capture what you learned so future sessions can benefit.

When to Use

  • After fixing a bug - What was the root cause? How did you find it?
  • After completing a feature - What approach worked? What didn't?
  • After research - What did you discover? What's the key insight?
  • When you notice a pattern - Something that works consistently

How to Capture

Quick Learning (one-liner)

squads learn "The auth token needs to be refreshed after 1 hour, not when the API returns 401"

With Context

squads learn "Always check memory before researching to avoid duplicate work" \
  --squad engineering \
  --category pattern \
  --tags "memory,research,efficiency"

Categories

  • success - Something that worked well
  • failure - Something that didn't work (learn from mistakes)
  • pattern - A reusable approach
  • tip - General advice

Workflow Integration

End of Task

Before marking a task complete, ask yourself:

  1. What worked that I should remember?
  2. What didn't work that I should avoid?
  3. Is there a pattern here worth capturing?

If yes to any → squads learn "<insight>"

Before Similar Tasks

Check existing learnings:

squads learnings search "auth"
squads learnings show engineering --tag auth

Examples

# After fixing a bug
squads learn "PostgreSQL connection pool exhaustion was caused by unclosed transactions in error paths" --category failure --tags db,postgres,connection

# After successful implementation
squads learn "Using TypeScript strict mode caught 3 type errors before runtime" --category success --tags typescript,types

# Noticing a pattern
squads learn "When context exceeds 70%, always run squads memory sync before continuing" --category pattern --tags context,memory

# General tip
squads learn "The gh CLI is faster than the GitHub API for simple operations" --category tip --tags github,cli

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.
