roadmap-build

roadmap-build is a skill for Claude Code, Codex from datacore-one/datacore. It costs 111 tokens per session (4,334 once invoked), scanned A, original, MIT.

A workflow for building a roadmap that agents can execute, rather than a document that only describes plans. It creates one validated YAML source, generated views, task links, an idea queue, and checks for inconsistencies.

In plain words
What is it for?
Use it to build or repair an agent-oriented roadmap, link tasks to larger work, define evidence for completion, and detect planning inconsistencies.
Why use it?
It helps keep plans aligned with the actual repository and exposes missing or outdated work through checks. This reduces drift between the roadmap and the codebase.

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.

Security

Grade A, and why

roadmap-build 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 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.

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 — 373 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Roadmap: build one agents can execute

Derived from rebuilding the PLUR roadmap, 2026-09-01 to 2026-09-03: five drifted documents to one validated source of 93 epics, 750 tasks, and three checks that catch regressions nobody would notice by reading.

The one thing that matters

A roadmap is good when it is CHECKABLE, not when it is well written.

Every structural finding in that rebuild came from a script, never from reading the file: five areas built and invisible, eleven epics whose repo state contradicted them, fourteen agent-doable tasks parked behind a wrong flag. The prose was fine throughout. The prose is always fine.

So: build the checks early and let them find the work. Do not write the whole roadmap and validate at the end.


Phase 1 — Find what is already true

Before writing anything, read the repos. Roadmaps decay by omission far more than by error, and the omissions are invisible from inside the document.

gh issue list --repo <org>/<repo> --state open --limit 200
gh pr list --repo <org>/<repo> --state open
git -C <repo> log --oneline -40
ls <repo>/src/<subsystem>/          # whole subsystems with no roadmap presence

Expect to find work that shipped and work that is invisible. In the PLUR rebuild: a provenance subsystem shipped in a repo the roadmap represented with two gated lines; eleven modules and three shipping tools with zero items; a 49-route admin surface with no coverage at all.

Ask of every subsystem: does the roadmap know this exists? Where it does not, that is an epic, and its status is whatever the code says — not what the document assumed.

Phase 2 — One writable source

Pick ONE file. Everything else becomes a generated view or a marked pointer.

Why fragmentation happens, and it is not carelessness: every document is writable, so ideas land in whichever one is open, and none is wrong enough to fix. The fix is not discipline. It is removing the ability to write.

Mark every other roadmap-shaped file with a canonical pointer naming what an item added there would be invisible to. Then add a check that flags a new unmarked one, because a sixth document is how the first five happened.

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-build is a skill published in the GitHub repository datacore-one/datacore (4 stars, last pushed today), licensed MIT. It adds 111 tokens to every session and 4,334 once invoked, about $0.0006 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 2026-09-05.
