Fix Claude -- Update

Augment an existing CLAUDE.md with production-grade agent directives. Preserves existing project-specific instructions while adding overrides for Claude Code's built-in limitations.

Workflow

Step 1: Resolve the Target File

If a specific path was passed (from the install router handling a symlink), use that path. Otherwise:

TARGET="CLAUDE.md"
if [ -L "$TARGET" ]; then
  TARGET=$(readlink -f "$TARGET")
  echo "Resolved symlink to: $TARGET"
fi

Step 2: Read the Existing File

Read the target file completely. Understand its structure:

• What sections does it have?
• What conventions does it follow?
• Is there a table of contents or numbered sections?

Step 3: Read the Template

Read the full template from:

${CLAUDE_PLUGIN_ROOT}/references/claude-md-template.md

Step 4: Analyze the Gap

Read the source leak findings reference for full context on what each directive fixes:

${CLAUDE_PLUGIN_ROOT}/skills/analyze/references/source-leak-findings.md

Compare the existing CLAUDE.md against all 7 findings. For each finding, determine whether the existing file already addresses it:

Finding	Check
1. Verification gate	Has forced verification / compile-check mandate?
2. Context death spiral	Has Step 0 cleanup / phased execution rules?
3. Brevity mandate	Has senior dev override / quality reframing?
4. Agent swarm	Has sub-agent swarming rules?
5. 2,000-line blind spot	Has file read budget / chunked read rules?
6. Tool result blindness	Has truncation awareness / narrow scoping rules?
7. grep not AST	Has multi-search mandate for renames?

Step 5: Merge Directives

For each missing or incomplete directive:

1. Extract the relevant sections from the template
2. Adapt the style to match the existing file's conventions (heading levels, formatting, tone)
3. Append new sections at the end of the file, under a clear heading:

---

## Agent Override Directives

> Production-grade overrides for Claude Code limitations.
> Based on https://github.com/iamfakeguru/claude-md (MIT, fakeguru)
> Installed by fixclaude plugin

4. Only add directives that are missing or significantly weaker than the template version
5. Do NOT duplicate directives that already exist in equivalent form
6. Do NOT rearrange or reformat existing content

Step 6: Write and Confirm

Write the updated file. Then tell the user:

• Which directives were added (list them)
• Which were already present and skipped
• The total number of overrides now in place
• Mention they can run fixclaude:analyze for a detailed gap analysis
