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 | $0.00009 | $0.05351 |
| Opus 5 | $0.00005 | $0.02676 |
| Sonnet 5 | $0.00002 | $0.01070 |
| Haiku 4.5 | $0.00001 | $0.00535 |
Grade A, and why
forge scanned grade A with 1 finding 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

/forge - Summon The Forge
The full pipeline: validate, implement, test, audit, and harvest — all in one command.
Runtime note — two forges, one metaphor. This is the IDE agent-driven
/forge: it orchestrates sub-agents through the phases below and gates each handoff with the Anvil (A0–A6). The canonical engine is the CLIsf forge(sf_clirunPipeline), which runs its own fixed, deterministic phase sequence and the CLI quality gates T0–T7. Same metaphor and phase vocabulary, different runtime and gate taxonomy by design. Use this skill inside an AI IDE; usesf forgefor a self-contained CLI run.
Usage
/forge Full Forge pipeline (semi-auto + parallel)
/forge [prd-file] Forge a specific PRD
/forge --blitz Forge with TDD enforcement
Instructions
You are The Forge — 46 rigorous agents forging production code. When /forge is invoked, execute the complete development pipeline from PRD to production-ready code.
When invoked:
Execute these phases in order:
Pre-Flight: Project Readiness
Before Phase 1, run these checks in order:
1. Git repository:
IF NOT a git repository (no .git/ directory):
AUTO-INITIALIZE:
git init && git add -A && git commit -m "initial commit"
OUTPUT:
✓ Git repository initialized with initial commit.
2. Execution context (per agents/_execution-context.md):
Read or detect .claude/execution-context.json. Display mode:
EXECUTION MODE: REAL | ADVISORY | DEGRADED
In ADVISORY mode, all test and build claims use qualified language throughout the forge run.
3. Stack profile (per agents/_stack-profile.md):
Read .claude/stack-profile.json. If missing, detect and write now. All execution agents in Phase 2 use this — never hardcoded commands.
4. Token budget estimate: Count total PRDs and estimate story count. Display before starting:
FORGE ESTIMATE
PRDs found: [N]
Est. stories: [N × avg 6]
Est. tokens: ~[N]k (varies by story complexity)
Proceed? This will run the full pipeline including /feature per story.
Use /forge --yes to skip this prompt.
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.

forge is a skill published in the GitHub repository samibs/skillfoundry (12 stars, last pushed 1mo ago), licensed MIT. It adds 9 tokens to every session and 5,351 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
