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 5.1 | $0.00024 | $0.00458 |
| Opus 5.5 | $0.00010 | $0.00183 |
| Sonnet 5.5 | $0.00005 | $0.00092 |
| Haiku 4.5 | $0.00002 | $0.00046 |
Grade A, and why
sdlc-modernize 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 1mo 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.
What it actually says
Industrial Legacy Modernization & Migration Command
This command enables safe extraction, characterization testing, and modern decoupling of legacy monoliths, stored procedures, and outdated frameworks without downtime or breaking changes.
Usage
/sdlc-modernize "legacy_policy_engine.c" --snapshot-tests # Create Golden Master characterization tests
/sdlc-modernize src/monolith/claims/ --pattern strangler # Generate Strangler Fig proxy & microservice slice
/sdlc-modernize "StoredProc_CalculatePremium" --pattern acl # Extract SQL procedure into typed domain service
Process
- Golden Master Characterization:
- Synthesizes automated snapshot tests recording inputs and outputs across all legacy edge cases.
- Anti-Corruption Layer (ACL) Generation:
- Wraps legacy types, raw SQL, and global state behind clean, typed interface seams.
- Strangler Fig Routing Setup:
- Creates dual-write and shadow-traffic proxy configs for incremental traffic migration.
- Expand & Contract Database Evolution:
- Generates zero-downtime migration scripts and backfill background workers.
Output Format
### 🏛️ Legacy Modernization Plan: [Target Module]
**Modernization Strategy**: Strangler Fig with Anti-Corruption Layer (ACL)
#### 🧪 Golden Master Characterization Suite
- Generated `tests/characterization/legacy_policy.spec.ts` (100% snapshot parity on 500 test scenarios)
#### 🔌 Anti-Corruption Layer (ACL)
- Created `src/domain/policy/policy.adapter.ts` (Translates legacy database records into domain models)
#### 🔄 Dual-Write & Shadow Traffic Configuration
- Proxy Route: `POST /api/v2/policies` (Shadow compares Legacy vs New Engine)
- Zero-Downtime Migration: Expand-Contract schema migration written to `migrations/20260813_policy_v2.sql`
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.

sdlc-modernize is a command published in the GitHub repository saitarrun/Devforge-ai (4 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 24 tokens to every session and 458 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
