Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00000 | $0.00551 |
| Opus 5 | $0.00000 | $0.00275 |
| Sonnet 5 | $0.00000 | $0.00110 |
| Haiku 4.5 | $0.00000 | $0.00055 |
Grade A, and why
pre-edit 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 2d 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.
This is a copy
100% identical to pre-edit — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.
hook pre-edit
Execute pre-edit validations and agent assignment before file modifications.
Usage
npx claude-flow hook pre-edit [options]
Options
--file, -f <path>- File path to be edited--auto-assign-agent- Automatically assign best agent (default: true)--validate-syntax- Pre-validate syntax before edit--check-conflicts- Check for merge conflicts--backup-file- Create backup before editing
Examples
Basic pre-edit hook
npx claude-flow hook pre-edit --file "src/auth/login.js"
With validation
npx claude-flow hook pre-edit -f "config/database.js" --validate-syntax
Manual agent assignment
npx claude-flow hook pre-edit -f "api/users.ts" --auto-assign-agent false
Safe editing with backup
npx claude-flow hook pre-edit -f "production.env" --backup-file --check-conflicts
Features
Auto Agent Assignment
- Analyzes file type and content
- Assigns specialist agents
- TypeScript → TypeScript expert
- Database → Data specialist
- Tests → QA engineer
Syntax Validation
- Pre-checks syntax validity
- Identifies potential errors
- Suggests corrections
- Prevents broken code
Conflict Detection
- Checks for git conflicts
- Identifies concurrent edits
- Warns about stale files
- Suggests merge strategies
File Backup
- Creates safety backups
- Enables quick rollback
- Tracks edit history
- Preserves originals
Integration
This hook is automatically called by Claude Code when:
- Using Edit or MultiEdit tools
- Before file modifications
- During refactoring operations
- When updating critical files
Manual usage in agents:
# Before editing files
npx claude-flow hook pre-edit --file "path/to/file.js" --validate-syntax
Output
Returns JSON with:
{
"continue": true,
"file": "src/auth/login.js",
"assignedAgent": "auth-specialist",
"syntaxValid": true,
"conflicts": false,
"backupPath": ".backups/login.js.bak",
"warnings": []
}
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.
