What it does

My Failure Museum is an agent skill from mohitagw15856/pm-claude-skills. Turn a mistake into a reusable lesson — a short, unsentimental 'here's what happened and the rule so it doesn't happen again' entry you can actually keep. Use when asked help me learn from this mistake, I keep making the same error, capture this lesson, or turn this failure into something useful. Produces an honest, blame-free autopsy of what happened, the real root cause (not the surface one), the specific rule or trigger that prevents a repeat, and a one-line entry for your growing 'failure museum' — because…

Its SKILL.md is about 970 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Root cause analysis. The repository describes itself as: 1255 professional Agent Skills for Claude, ChatGPT, Gemini, Cursor & Codex — PRDs, postmortems, leases, medical bills, layoffs, go-bags, new countries. Plain markdown, MIT, in… The licence is MIT.

When your agent uses it

  • Asked help me learn from this mistake
  • I keep making the same error
  • Capture this lesson
  • Turn this failure into something useful

Example prompts

  • “s what happened and the rule so it doesn”
  • “failure museum”
  • “/my-failure-museum”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Examine, don't flagellate. Approach it like an investigator, not a judge — blame shuts down learning; curiosity opens it.
  2. Dig past the surface cause. "I forgot" or "I was busy" is rarely the real cause — find the system or habit underneath ("no reminder…
  3. Extract a specific rule. Convert the root cause into an actionable rule or trigger ("before saying yes, check the calendar"; "always CC…
  4. Write the one-liner. Compress it into a single memorable entry for the museum — short enough to actually reread.
  5. Check the pattern. If this echoes past failures, name the recurring theme — that's the higher-leverage fix.

What it can do on your machine

Read from SKILL.md and the folder at commit 1cbf1f0. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

My Failure Museum loads about 965 tokens when it runs. Until then it costs about 150 tokens; SKILL.md has 483 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~150
When it runs · the whole SKILL.md, loaded when a task matches
~965

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Turn a mistake into a reusable lesson — a short, unsentimental 'here's what happened and the rule so it doesn't happen again' entry you can actually keep. Use when asked help me learn from this mistake, I keep making the same error, capture this lesson, or turn this failure into something useful. Produces an honest, blame-free autopsy of what happened, the real root cause (not the surface one), the specific rule or trigger that prevents a repeat, and a one-line entry for your growing 'failure museum' — because unexamined mistakes repeat and examined ones compound into wisdom.

My Failure Museum

A mistake you don't examine is one you'll make again; a mistake you turn into a rule never costs you twice. This does the turning: a short, honest, blame-free autopsy of what went wrong, the real root cause underneath the obvious one, and the specific rule or trigger that stops the repeat — captured as a one-line entry for a growing collection. Over time, your failure museum becomes your hardest-won operating manual.

What This Skill Produces

  • The honest autopsy — what actually happened, blame-free (self-flagellation teaches nothing; analysis does)
  • The real root cause — the underlying reason, not the surface one ("I was busy" → "I don't build in buffer time")
  • The prevention rule — a specific, actionable rule or trigger that would have caught it, and will next time
  • The one-line museum entry — a compact, keepable lesson to add to your collection
  • A pattern check — whether this is a one-off or part of a recurring theme worth a bigger fix

Required Inputs

Ask for these if not provided:

  • What happened — the mistake or failure
  • The consequence — what it cost
  • Your read on why — your first explanation (we'll dig past it)
  • Has it happened before — to spot a pattern

Framework: Autopsy Without Blame, Extract The Rule

  1. Examine, don't flagellate. Approach it like an investigator, not a judge — blame shuts down learning; curiosity opens it.
  2. Dig past the surface cause. "I forgot" or "I was busy" is rarely the real cause — find the system or habit underneath ("no reminder system," "I over-commit").
  3. Extract a specific rule. Convert the root cause into an actionable rule or trigger ("before saying yes, check the calendar"; "always CC myself"). Vague resolutions don't work; specific rules do.
  4. Write the one-liner. Compress it into a single memorable entry for the museum — short enough to actually reread.
  5. Check the pattern. If this echoes past failures, name the recurring theme — that's the higher-leverage fix.

Output Format

Failure: [what happened] · cost: [consequence]

Autopsy (blame-free): [what actually happened]. Real root cause: [the underlying system/habit, past the surface]. Prevention rule: [specific, actionable rule or trigger]. 📓 Museum entry (one line): "[compact lesson]." Pattern? [one-off / part of a recurring theme → the bigger fix].

Quality Checks

  • The autopsy is honest but blame-free
  • It digs past the surface cause to the real one
  • The prevention is a specific rule/trigger, not a vague resolution
  • It produces a compact, keepable one-line entry
  • It checks whether this is part of a pattern

Anti-Patterns

  • Self-flagellation dressed as reflection.
  • Stopping at the surface cause ("I was careless").
  • A vague resolution ("I'll be more careful") instead of a rule.
  • Missing the recurring pattern.

Example Trigger Phrases

  • "I messed up — help me actually learn from it."
  • "I keep making the same mistake. Why, and how do I stop?"
  • "Turn this failure into a lesson I'll remember."
  • "Do a blame-free post-mortem on my screw-up."
  • "Add this to my list of lessons — what's the rule?"
