Minimap

Minimap

How a mini-spec project is laid out, so you can find your way around it — read it, search it, follow a clue from any layer to the others. This is the model, not the process. Load /minimap to navigate; load /mini-spec to maintain (it loads this skill underneath).

Design docs first — not code

When understanding a feature or planning a change, start with design/design.md and the relevant CRC cards/sequences before using code-exploration tools (grep, symbol search, reading source). Design docs are the project index — they show component relationships, responsibilities, and code-file mappings more efficiently than reading code. Drop into code-level tools only after the design docs have oriented you. And when the project keeps a root spec index (below), read that first of all — it maps every spec in one file, so you orient without grepping the specs/ tree.

The three levels

specs/                # Human intent — current state, in the user's own words
  migrations/         # In-flight migrations — temporary, moved on completion
    complete/         # Completed migrations, numbered in landing order
design/               # AI translation — requirements.md, crc-*, seq-*, ui-*, test-*, manifest-ui.md
docs/                 # user-manual.md, developer-guide.md
src/                  # Code with traceability comments

(src/ stands in for the project's code root, whatever it's named.)

Specs are the human's voice — what the system should do, in natural language, organized by feature area. Intent, not implementation. For libraries, API signatures live in specs because they are the contract. Most specs are per-feature (one spec, one capability). A second kind, summary specs, indexes existing behavior along a cross-cutting axis without adding behavior of its own (below).

Design is the AI's translation of specs into buildable structure. requirements.md extracts testable statements; CRC cards assign responsibilities to components; sequences show how components interact.

Code implements the design, carrying traceability comments that link each piece back to the design artifacts and requirements that justify it.

The root spec index

A project with many specs keeps a root index — one file (e.g. specs/index.md) that maps every per-feature spec by system, registers the summary specs, and names the cross-cutting themes. The per-feature specs are the leaves; the index is the root that says where to look.

Use it to orient cheaply. Read the root index first — at session start, or before working in an unfamiliar area — then open only the specs it points you to. One small read replaces grepping the whole specs/ tree or opening files just to learn what they cover; orientation drops from O(corpus) toward O(1) tokens. This is the spec-level companion to Design docs first.

Entries are pointers, not copies — the named spec stays canonical, the index mirrors it. A theme gathers every spec a cross-cutting concern touches and states its invariant once, so contradictions between leaves become visible. (Keeping the index complete is a maintenance task — /mini-spec owns it.)

Summary specs

A summary spec doesn't introduce behavior — it indexes behavior owned by per-feature specs, along one cross-cutting axis. Per-feature specs answer "what does this feature do?"; summary specs answer "what's the full set of X in this project?" Recurring kinds:

• CLI inventory — every subcommand and flag (e.g. specs/cli-commands.md).
• Storage layout — every record class with key/value layout (e.g. specs/record-formats.md).
• API surface — every public binding exposed to a scripting/extension layer (e.g. specs/lua-api.md).
• Capabilities — every named feature with motivation and objective (e.g. specs/features.md).

For navigation: per-feature specs are canonical; summary specs are mirrors. When the two disagree, trust the per-feature spec. (Keeping the mirrors in sync is a maintenance task — /mini-spec owns it.)

Traceability — the links you follow

The three levels are stitched together by a chain of grep-able references. This is what lets you start from a vague clue in any layer and follow it to the others — the core navigation move.

spec item ──> requirement (Rn) ──> design artifact (CRC card / sequence) ──> code (// CRC:/Seq:/Rn)

• Requirements are numbered, testable statements — R1, R2, … —

globally numbered across all features, living in design/requirements.md. Each spec item becomes exactly one Rn.

• CRC cards (design/crc-*.md) assign responsibilities to a component:

a ## Knows / ## Does / ## Collaborators body, with a top-line **Requirements:** R1, R3, R7 naming the requirements it covers.

• Sequences (design/seq-*.md) show component interactions. Steps are

numbered with dotted IDs (1.4), so code can pin to a specific step.

• Code carries traceability comments naming the artifacts that justify it:

`` // CRC: crc-Store.md | Seq: seq-crud.md#1.4 | R4, R5 ``

The | Rn, Rn tail is optional but common — it links a specific code location straight to requirements.

Following a thread (both directions):

• Requirement → everywhere it lands: grep -rn "R5" design/ src/
• Sequence step → its implementations: grep -rn "seq-crud.md#1.4" src/
• Code → its justification: read the // CRC:/Seq:/Rn comment, open that

artifact, follow its **Requirements:** line back to the spec.

• Spec → its code: spec → find the Rn in requirements.md → grep that Rn.

The links are bidirectional by design: every artifact points down toward code and the comments point back up toward intent, so a clue in one layer reaches all three.

Retired requirements still resolve. A requirement obsoleted by a later change is rewritten in place as **~~R5:~~** (Retired Tn — see R10) , so an old reference in design or code still leads somewhere — to the replacement (or to "no replacement"). Don't read a struck-through Rn as a dead end; it's a forwarding address.
