altimate-code: Command for Claude Code

.opencode/command/learn.md

learn is a command for Claude Code, OpenCode from AltimateAI/altimate-code. It costs 18 tokens per session (344 once invoked), scanned A, original, MIT.

Extract non-obvious learnings from session to AGENTS.md files to build codebase understanding.

Command for Claude CodeOpenCode

Written for Claude Code and OpenCode: $ARGUMENTS substitution, but also installed under .opencode/. Also seen: mentions AGENTS.md.

This is AltimateAI/altimate-code's own configuration. It tells Claude Code and OpenCode how to work on altimate-code 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 altimate-code 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

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 today.

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

Analyze this session and extract non-obvious learnings to add to AGENTS.md files.

AGENTS.md files can exist at any directory level, not just the project root. When an agent reads a file, any AGENTS.md in parent directories are automatically loaded into the context of the tool read. Place learnings as close to the relevant code as possible:

  • Project-wide learnings → root AGENTS.md
  • Package/module-specific → packages/foo/AGENTS.md
  • Feature-specific → src/auth/AGENTS.md

What counts as a learning (non-obvious discoveries only):

  • Hidden relationships between files or modules
  • Execution paths that differ from how code appears
  • Non-obvious configuration, env vars, or flags
  • Debugging breakthroughs when error messages were misleading
  • API/tool quirks and workarounds
  • Build/test commands not in README
  • Architectural decisions and constraints
  • Files that must change together

What NOT to include:

  • Obvious facts from documentation
  • Standard language/framework behavior
  • Things already in an AGENTS.md
  • Verbose explanations
  • Session-specific details

Process:

  1. Review session for discoveries, errors that took multiple attempts, unexpected connections
  2. Determine scope - what directory does each learning apply to?
  3. Read existing AGENTS.md files at relevant levels
  4. Create or update AGENTS.md at the appropriate level
  5. Keep entries to 1-3 lines per insight

After updating, summarize which AGENTS.md files were created/updated and how many learnings per file.

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.

learn is a command published in the GitHub repository AltimateAI/altimate-code (805 stars, last pushed yesterday), licensed MIT. It adds 18 tokens to every session and 344 once invoked, about $0.0001 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 2026-09-06.
