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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00053 | $0.02827 |
| Opus 5 | $0.00026 | $0.01413 |
| Sonnet 5 | $0.00011 | $0.00565 |
| Haiku 4.5 | $0.00005 | $0.00283 |
Grade A, and why
software-design-lifecycle-tech-detailed-core-flow-diagramming 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 12d 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.

Technical Detailed Core Flow Diagramming
Overview
This skill now directly contains the merged specialist doctrine that previously lived in the legacy core-functional-flow skill.
Integrated Legacy Specialist Doctrine (Preserved and Merged)
Core Functional Flow Diagramming
Overview
This is the architect-private skill for drawing and reviewing 核心功能流程图 in the 详细设计 stage.
Its job is narrow in lifecycle position but intentionally complete in method. It combines:
- the architecture-lifecycle doctrine for
技术方案设计 → 详细设计 → 关键流程 - the branch-completeness discipline needed for design review
- the full drawing specification, preserved in linked references instead of being compressed away
- the ready-to-use templates needed to turn the method into an actual deliverable
Core principle: 核心功能流程图 belongs to detailed design. It explains dynamic handling logic and branch completeness, not overview capability layering, business-solution framing, deployment topology, or schema/interface inventories.

What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

software-design-lifecycle-tech-detailed-core-flow-diagramming is a skill published in the GitHub repository xiaohei-info/oh-my-multica (26 stars, last pushed 5d ago), licensed MIT. It adds 53 tokens to every session and 2,827 once invoked, about $0.0003 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 2026-08-30.

cw-gates
Use before claiming any Codewhale change is done, green, or ready to land: the focused-to-broad verification ladder, the budget checks CI enforces, and the rules for what counts as a passing test.
interview
Ask one useful structured question at a time only when material product/implementation choices are genuinely missing; remember answers and produce a brief/spec. Discoverable facts should be investigated instead of asked.
verify
Exercise the real app/API/CLI and collect observable evidence; tests alone do not count as end-to-end verification.
mcp-host-styling-integration
Integrates MCP App UI with host theming system. Applies host CSS variables, handles onhostcontextchanged, safe area insets, display mode detection, and fullscreen configuration.
quality-hooks
Language-specific auto-lint/format/typecheck pipeline. Supports Python (ruff+pyright), TypeScript (prettier+eslint+tsc), Go (gofmt+golangci-lint). Auto-fix and convergence loops.
dd-synthesis
Synthesize findings from multiple specialist agents into a coherent investment recommendation. Use when combining reports from 9+ specialist agents into a single decision document.
