Correcting Mistakes in Skills and Commands

Trigger this skill when:

1. You error during execution of a skill or command and eventually work out a solution
2. The user indicates you made a mistake in executing a skill or command
3. Claude fails during skill or command execution due to an edge case

Workflow

Step 1: Locate the Instruction File

Find the relevant file that needs correction:

• Skills: .claude/skills/{skill-name}/SKILL.md or reference files
• Commands: .claude/commands/{command-name}.md

Read the file to understand the current instructions.

Step 2: Diagnose the Root Cause

Determine: Was this your misunderstanding, or an instruction issue?

Your misunderstanding (stop here, no changes needed):

• You misread or misapplied clear instructions
• The instruction was correct but you made an execution error
• Context from the conversation led you astray, not the instruction

Instruction issue (proceed to Step 3):

• The instruction was ambiguous, misleading, or incomplete
• An edge case was found that the skill or command doesn't account for
• The instruction specified an incorrect approach
• The instruction omitted a critical step or detail

Step 3: Test Before Fixing (if applicable)

If the correction involves a script, command, or tool use:

1. Test the correct approach in the current session
2. Verify it works as expected
3. Only proceed to Step 4 after confirmation

This prevents codifying a "fix" that doesn't actually work.

Step 4: Apply the Correction

Edit the instruction file with these principles:

Write for a reader with no memory of the error:

• State the correct approach directly
• Do not reference the mistake, the error, or what was wrong before
• Do not add "Note:" or "Important:" warnings about the pitfall
• Do not explain why this is correct (unless explanation is inherently useful)

Be succinct:

• Change only what's necessary
• Preserve the existing style and structure
• Avoid adding defensive caveats or extra context

Example - Good correction:

# Before (incorrect)
Use `synthesis.md` as the template.

# After (correct)
Use `./templates/research-synthesis.md` as the template.

Example - Bad correction (too verbose, references error):

# After (bad - references the error)
Use `./templates/research-synthesis.md` as the template.
Note: The file is named research-synthesis.md, not synthesis.md.

Step 5: Confirm

After applying the fix:

1. Re-read the corrected section to verify it reads naturally
2. Confirm the fix is self-contained (no orphaned references to removed content)
3. Inform the user what was corrected
