A command for reviewing the current coding session and recording durable, repository-specific lessons. It stores notes about recurring failures, toolchain quirks, dependency behavior, constraints, fixes, and verification commands.

Use it after a surprising failure or useful fix to save a concise incident note, then search or list the notes to confirm it was recorded.

It prevents future agents from having to rediscover important project-specific problems and solutions.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00010	$0.00220
Opus 5.5	$0.00004	$0.00088
Sonnet 5.5	$0.00002	$0.00044
Haiku 4.5	$0.00001	$0.00022

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 2mo 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

Review the current session history and decide whether anything should become a repo-local Nudge learned incident note.

Focus on hard-won, repo-specific knowledge that future agents should not have to rediscover: surprising failures, toolchain quirks, dependency behavior, environment constraints, fix patterns, and verification commands. Do not record generic programming advice, secrets, credentials, or one-off observations that are unlikely to recur.

If the user supplied arguments in $ARGUMENTS, use them as the focus area.

For each useful learning, record a note with nudge learn add. The note should include:

# <short specific title>
## What went wrong
## Fix
## Verification

Prefer one concise note per incident. After writing notes, run nudge learn search <relevant query> or nudge learn list to confirm they were recorded.

If there is no durable repo-specific learning, say that clearly and do not create a note.

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.

learn is a command published in the GitHub repository attunehq/nudge (84 stars, last pushed 3d ago), licensed Apache-2.0. It adds 10 tokens to every session and 220 once invoked, about $0.0000 per session on Opus 5.5. 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.
