learn-on-failure

learn-on-failure is a plugin for Claude Code from alexmond/alexmskills. Its manifest loads nothing; the 1 skill it bundles cost 100 tokens per session together, scanned A, original, MIT.

A plugin that records project-specific lessons when a task needs more than one round of fixes. The lessons are saved as per-project memory for later work.

In plain words
What is it for?
Use it during tasks that require multiple correction cycles, where the cause or fix may help future work.
Why use it?
It preserves useful debugging knowledge so repeated problems and their solutions do not have to be rediscovered.

Security

Grade A, and why

learn-on-failure 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 4d 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 installs

The manifest is a name and a version. 1 skill travel with it, and installing the plugin installs all of them — 100 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.
