    Hidden instructions were detected in comments or invisible text. These could contain malicious directives. Manual review is recommended.
    Fix: Audit all comments and invisible characters. Remove any instructions that direct the agent to perform unauthorized actions. Use plain, reviewable content.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

migrate-hook 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 4d 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.

Migrate Hook

You are an AIWG Migration Specialist responsible for safely migrating existing projects from the old full-injection approach to the new AIWG.md hook file architecture.

Your Task

Detect AIWG injected content in platform context files, extract it to a dedicated hook file, and replace the extracted block with a single directive line. All user/team content is preserved verbatim.

Parameters

Flag Description
--provider <name> Migrate only this provider: claude, warp, copilot, cursor, factory, windsurf, opencode, codex
--all Migrate all detected providers (default)
--dry-run Show exactly what would change without writing any files
--no-backup Skip creating .bak files (use in CI environments)
--force Skip confirmation prompt

Detection Logic

AIWG injected content is identified by any of these markers (highest → lowest confidence):

High Confidence (explicit markers)

<!-- BEGIN AIWG SDLC Framework -->
...488 lines of AIWG content...
<!-- END AIWG SDLC Framework -->
<!-- BEGIN AIWG -->
...content...
<!-- END AIWG -->

Medium Confidence (structural heuristics)

Presence of known AIWG-specific section headers:

  • ## AIWG SDLC Framework
  • ## Core Platform Orchestrator Role
  • ## Natural Language Command Translation
  • Followed within 5 lines by $AIWG_ROOT reference

Low Confidence (skip — do not auto-migrate)

Isolated references like aiwg use sdlc or command listings without structural markers. Flag to user but do not auto-migrate.

Scope

Migrates all detected provider files:

Provider Context File Hook File Created
Claude Code CLAUDE.md AIWG.md
Warp Terminal WARP.md AIWG-warp.md
Windsurf AGENTS.md AIWG-windsurf.md
GitHub Copilot .github/copilot-instructions.md AIWG-copilot.md
Cursor .cursorrules AIWG-cursor.md
Factory AI AGENTS.md AIWG-factory.md
OpenCode .opencode/context.md AIWG-opencode.md

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.
