Per-feature Mermaid flowchart — routes / models / jobs / screens. Consumes /extract-features inventory.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

Writing: read docs/skills/shared/writing-rule.md before you write a durable artifact.

# /feature-diagram — Per-feature Mermaid Sub-graph

Reads the Feature Inventory at `projects/<name>/feature-inventory.md` (produced by `/extract-features`) and writes a per-feature Mermaid `flowchart LR` showing the **HTTP routes, data models, async jobs, and UI screens** that participate in one feature. Output: `projects/<name>/features/<slug>.md` (one file per feature).

This skill closes the gap left by the rest of the architecture-doc family:

| Skill | Slice |
|-------|-------|
| `/c4` | Whole-system topology (L1 + L2) |
| `/dfd` | Whole-system data flows + trust boundaries |
| `/process` | One business process (BPMN control flow) |
| `/journey` | One feature, product-facing user flow (HTML modal-per-page) |
| `/feature-diagram` (this skill) | **One feature, architectural slice** (Mermaid flowchart) |

See `AgDR-0035-per-feature-diagrams.md` for the design rationale.

## Path resolution

Read the per-project docs dir via `portfolio_projects_dir` from `.claude/hooks/_lib-portfolio-paths.sh`. Source the helper at the top of any bash block that touches that path:

```bash
…

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint
mdr add me2resh/apexyard/feature-diagram@sha256:d6ad0f29d5f99734

The line at the top of this page pins the label git:20261015.37f5689, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
