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 | $0.00835 | $0.00835 |
| Opus 5 | $0.00417 | $0.00417 |
| Sonnet 5 | $0.00167 | $0.00167 |
| Haiku 4.5 | $0.00084 | $0.00084 |
Grade A, and why
Stage_Manager_Skills CLAUDE.md 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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 61 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Stage Manager — Artful Making Skill Library
A collection of 16 skills for vibe coders who use agentic coding tools (Claude Code, Cursor, Replit). Skills are organized across the Shape-to-Stage flow cycle, including premise validation before building. The mirror never goes dark.
Available Slash Commands
Shape (analyze before building)
/sm:shape:find-holes— Find specification gaps where coding tools will invent behavior/sm:shape:collapsed-options— Find decisions made before the builder knew they were making them/sm:shape:risk-sequence— Surface load-bearing assumptions and sequence by cost-if-wrong/sm:shape:soul-check— Deep read on whether the original animating idea is still alive/sm:shape:brief— Synthesize shape skill output into ranked top-three problems, inline change suggestions,Stage_Manager_Brief.md, and[Spec_Name]-Staged.md— the handoff to CE or Superpowers
Transition
/sm:shape:gate— Five readiness questions before crossing from shaping to staging
Stage (before, during, and after the build)
/sm:stage:chunking— Break work into flow-cycle-sized pieces sequenced by cost of delay (economic, risk, flow, joy)/sm:stage:prompt-craft— Turn shaped chunks into scoped, guardrailed prompts/sm:stage:live-mirror— Compare plan vs. code output per-session, surface what the tool invented/sm:stage:decision-capture— Full decisions-made manifest after a build, feeds forward into learning
Validate (before you build, prove the premise)
/sm:yagni— Gate: challenge the premise before a single line of code/sm:invalidate-prep— Surface and rank assumptions, identify personas, generate problem statements/sm:invalidate-interview— Generate a live interview script using negative framing to kill assumptions/sm:invalidate-score— Score each assumption as validated, invalidated, or still open
Any Node
/sm:coherence-check— Lightweight 2-minute gate at any transition point mid-build. For the shape/stage boundary, use/sm:shape:briefinstead./sm:stage-manage— Session opener and orchestrator. Watches for signals and suggests skills as they emerge.
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.

Stage_Manager_Skills CLAUDE.md is an instructions file published in the GitHub repository mnfst-ai/Stage_Manager_Skills (5 stars, last pushed 3mo ago), licensed MIT. It adds 835 tokens to every session, about $0.0042 per session on Opus 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.
