learn

根据对话学习结果更新fx-cc插件代理、技能或命令。当用户说“使用/learn to...”、“学会...”、“记住...”或“不要再做X了”，或者当代理/技能表现异常需要纠正时，使用此技能。此技能会修改插件源文件，但不会自动提交更改——提交前需人工审核。

description: Update fx-cc plugin agents, skills, or commands based on conversation learnings. Use when the user says "use /learn to...", "learn to...", "remember to...", "don't do X again", or when an agent/skill misbehaved and needs correction. This skill modifies plugin source files but does NOT commit changes - they require manual review before committing.

Learn

This skill updates fx-cc marketplace plugins based on learnings from the current conversation. It modifies agent, skill, or command definitions to prevent future mistakes or improve behavior.

Prerequisites

Before making any changes, verify the fx-cc marketplace is accessible:

bash
cd ~/.claude/plugins/marketplaces/fx-cc && git remote -v && git status

The remote must be git@github.com:fx/cc.git. If not accessible, inform the user and abort.

Workflow

Step 1: Analyze the Learning Request

Examine the current conversation to understand:

  1. •What went wrong - Identify the specific behavior that needs correction
  2. •Root cause - Determine which agent, skill, or command caused the issue
  3. •Desired behavior - Understand what should happen instead

Common scenarios:

  • •Skill not loaded when it should have been → Update skill description to be clearer about trigger conditions
  • •Agent did something it shouldn't → Add explicit prohibition to agent instructions
  • •Agent missed a step → Add the step to the agent's workflow
  • •Instruction was ambiguous → Clarify the wording

Step 2: Locate Relevant Files

Search the fx-cc marketplace for relevant files:

bash
# Find all plugin definitions
find ~/.claude/plugins/marketplaces/fx-cc/plugins -name "*.md" -type f

# Search for specific content
grep -r "keyword" ~/.claude/plugins/marketplaces/fx-cc/plugins/

Key locations:

  • •Agents: plugins/<plugin>/agents/<agent>.md
  • •Skills: plugins/<plugin>/skills/<skill>/SKILL.md
  • •Commands: plugins/<plugin>/commands/<command>.md

Step 3: Make Targeted Modifications

Edit the relevant files to address the learning. Follow these principles:

  1. •Be specific - Add concrete instructions, not vague guidance
  2. •Use imperative form - Write "Do X" or "Never do Y", not "You should..."
  3. •Add context - Explain why the rule exists if non-obvious
  4. •Preserve structure - Maintain existing formatting and organization

For prohibitions, use clear language:

markdown
**CRITICAL:** Never do X because Y.

For required actions:

markdown
**IMPORTANT:** Always do X before Y.

Step 4: Sync to Plugin Cache

CRITICAL: Claude Code caches plugins separately from the marketplace source. After modifying files in the marketplace, sync changes to the cache so they take effect immediately.

Cache mapping:

  • •Source: ~/.claude/plugins/marketplaces/fx-cc/plugins/<plugin>/
  • •Cache: ~/.claude/plugins/cache/fx-cc/<plugin>/<version>/

To sync a modified plugin:

bash
# Get the plugin version from its manifest
PLUGIN=fx-dev  # or fx-meta, fx-research, etc.
VERSION=$(cat ~/.claude/plugins/marketplaces/fx-cc/plugins/$PLUGIN/.claude-plugin/plugin.json | grep '"version"' | sed 's/.*: *"\([^"]*\)".*/\1/')

# Sync marketplace source to cache
rsync -av --delete \
  ~/.claude/plugins/marketplaces/fx-cc/plugins/$PLUGIN/ \
  ~/.claude/plugins/cache/fx-cc/$PLUGIN/$VERSION/

Sync every plugin that was modified. This ensures Claude loads the updated definitions immediately without requiring a restart.

Step 5: Verify Changes

After editing and syncing, show the diff to the user:

bash
cd ~/.claude/plugins/marketplaces/fx-cc && git diff

Step 6: Leave for Manual Review

CRITICAL: Do NOT commit the changes. Inform the user:

Changes have been made to the following files:

  • •path/to/file1.md
  • •path/to/file2.md

Review the changes with git diff in ~/.claude/plugins/marketplaces/fx-cc. Commit manually when satisfied.

Examples

Example 1: Agent Skipped a Step

User says: "use /learn to update our sdlc agents - they should update PROJECT.md when creating PRs"

  1. •Locate plugins/fx-dev/agents/pr-preparer.md
  2. •Add instruction to check PROJECT.md and update completed tasks
  3. •Sync fx-dev plugin to cache
  4. •Show diff, leave uncommitted

Example 2: Skill Not Triggered

User says: "the github skill didn't load when I ran gh commands"

  1. •Locate plugins/fx-dev/skills/github/SKILL.md
  2. •Update description to include more trigger phrases (e.g., "gh CLI", "GitHub API")
  3. •Sync fx-dev plugin to cache
  4. •Show diff, leave uncommitted

Example 3: Explicit Prohibition

User says: "/learn to never leave comments on PRs"

  1. •Locate relevant agents (pr-preparer, pr-reviewer, etc.)
  2. •Add explicit prohibition with rationale
  3. •Sync all modified plugins to cache
  4. •Show diff, leave uncommitted
