A rewrite-planning skill that divides an accepted software architecture into vertical slices. Each slice is a complete capability, such as a user or operator goal, rather than a group of models or controllers.

Use it after architecture design to create an interview.md handoff and a scratchpad for each slice. It helps plan a rewrite in small end-to-end increments and show which decisions remain assumed or unresolved.

It gives implementation work a clear order, puts the riskiest capability early, and passes explicit requirements, decisions, and acceptance checks to the next planning step. TDD means test-driven development; this tool instead focuses on defining the slice and its evidence before implementation.

Token cost

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	$0.00045	$0.02383
Opus 5.5	$0.00018	$0.00953
Sonnet 5.5	$0.00009	$0.00477

Security

Grade B, and why

roadmap scanned grade B 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 today.

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.

The opening of the file, as written. The whole thing — 183 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Rewrite Roadmap — Slices and phx Handoff

Phase 3. Cut the accepted architecture into vertical slices that each prove capabilities end to end, then hand one slice at a time to the phx workflow. The handoff is a file contract: interview.md that /phx:plan already consumes, plus a scratchpad seed. phx is not modified.

/rewrite:architect → /rewrite:roadmap  <-- YOU ARE HERE
                          ↓  interview.md + scratchpad.md
                     /phx:plan → /phx:work → /rewrite:verify → /rewrite:roadmap --next

Iron Laws

SLICES ARE CAPABILITIES — each slice delivers user, operator or machine goals end to end, never "all models" or "all controllers"
RISK FIRST — the first product slice is the riskiest core capability, after a foundation slice
NO FABRICATED INTERVIEW — the seed says it was generated, keeps ASSUMED and UNDECIDED visible, and has no invented transcript
COMPLETE ONLY WHEN EARNED — every coverage dimension ≥1, total ≥8, no UNDECIDED row and no unresolved consequential decision in the slice
NEVER OVERWRITE USER WORK — check an existing plan directory before writing; never hand phx any file but the slice's own interview.md
NO HANDOFF ON UNRESOLVED DECISIONS — never invoke /phx:plan while a consequential decision for the slice is ASSUMED, proposed or pending
phx OWNS APPROVAL — /phx:plan stops for approval; never auto-start /phx:work

Workflow

1. Preconditions

Require ADR-000 with Status accepted or ASSUMED, architecture.md and a clean ledger:

python3 "${CLAUDE_SKILL_DIR}/../architect/scripts/ledger.py" check --rewrite-dir .claude/rewrite

If the check fails, stop and suggest /rewrite:architect.

2. Build or update `roadmap.md`

Skip to step 3 with --next or --slice when roadmap.md already exists. Otherwise read ${CLAUDE_SKILL_DIR}/references/slicing.md and write .claude/rewrite/roadmap.md in this conversation (a delegated writer is a general-purpose agent with model: "sonnet"), in this order:

What ships with it

2 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.

Changes

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.

roadmap is a skill published in the GitHub repository oliver-kriska/claude-elixir-phoenix (567 stars, last pushed today), licensed MIT. It adds 45 tokens to every session and 2,383 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-17.
