roadmap-writing

When to use

• Authoring a new roadmap file in agents/roadmaps/{name}.md (or module-scoped under {module_root}/{Module}/{agent_folder}/roadmaps/ — per modules.root_paths + modules.agent_folder; Laravel shape: app/Modules/{Module}/agents/roadmaps/)
• Rewriting an existing roadmap (phase restructure, goal pivot, council-pass integration — not a checkbox flip)
• Drafting a phase block, exit criteria, or rollback section that will land inside an existing roadmap — an operator symptom as the input has its own entry procedure: symptom-driven harvest

Do NOT use this skill when:

• Flipping checkboxes, regenerating the dashboard, archiving on completion → use roadmap-management
• Updating AGENTS.md / module docs / contexts → use agent-docs-writing
• Capturing an architectural decision → use adr-create

Roadmap-writing vs roadmap-management — critical test

Intent	Artifact
"I need to write the plan body"	roadmap-writing (this skill)
"I need to track progress / regenerate dashboard / archive"	roadmap-management

This skill owns the prose authoring axis: structure, goal sentence, phase blocks, acceptance criteria. The execution and dashboard-sync axis stays in roadmap-management.

Procedure

0. Drafting protocol

Authoring or materially rewriting a roadmap must go through Understand → Research → Draft per the artifact-drafting-protocol rule. Run the probe, do not eyeball the directory:

agent-config roadmap:context

It reports sibling roadmaps on the same topic across all four roadmap directories, inbox notes, and open PRs on the cited paths — the semantic axis a filename scan cannot see. Each hit becomes one relates: row (extends / supersedes / depends / disjoint, template rule 18); zero hits becomes relates: [] carrying the probe's scanned: line as its justification. Gate C first — "write a plan/roadmap" is a gated surface, so run plan-confidence-gate before drafting (95%-conditions, marker, interview-or-degrade, C→R1 handoff).

1. Read the canonical template first

The structure, frontmatter, lifecycle, and complexity-tier rules live in src/agent-src/templates/roadmaps.md. Read it before authoring. Do not restate its rules in the roadmap body — link the template if a phase needs to override one.

Naming: a lone roadmap is road-to-<slug>.md. When you create ≥2 related roadmaps in one pass (siblings split from one body of work, or a follow-up chain), give them a shared road-to-<family>-<part>.md prefix so relatedness is visible and the dashboard groups them — pick the <family> slug up front (template rule 21). Follow-ups additionally carry parent_roadmap: (rule 17).

2. Pick complexity tier honestly

Default lightweight (≤ 6 phases, ≤ 600 lines). Only use structural when the change touches a contract, kernel rule, or budget invariant — the complexity linter enforces it. Standard: roadmap-complexity-standard.

3. Write the goal first

One sentence, top of file, decidable: "Reduce X by Y on flow Z." Vague goals ("improve roadmaps") force every reader to re-derive intent. If the goal needs three sentences, the roadmap is two roadmaps.

3b. Scan sources for discrepancies before drafting phases

When the roadmap originates from a ticket/spec that carries a second source — an attached mockup/screenshot, a code reality, or an internal contradiction — run the cross-source discrepancy scan (per cross-source-consistency) before writing phases. A phase plan built over a text↔image contradiction or a silent-but-needed behavior (weekend/holiday shift, empty/error state) bakes the wrong assumption into every downstream step. Surface each discrepancy as one batched open question first; an inferred behavior is a scope expansion to confirm, not to plan silently. Taxonomy + procedure: cross-source-consistency-mechanics.

4. Phase blocks carry checkboxes

Every non-intro phase contains at least one - [ ]. Decision tables and council-pass notes capture the why; checkboxes capture the what to do next. Without checkboxes the phase is invisible to agents/roadmaps-progress.md — enforced by roadmap-progress-sync Iron Law #2.

Bind a verify: on behavior-changing steps. A step that changes behavior (a new guard, a migration, a wired endpoint, a mechanism edit) SHOULD carry a narrow verify: command in an inline annotation — - [ ] Wire the guard <!-- verify: task test -- --filter=GuardTest --> — so its [x] flip is machine-checkable, not just agent-asserted (template rule 23; enforced by the flip-guard). Bind it only where a single narrow command (targeted test / grep / build of the touched surface) proves the step; leave it off doc-only / prose steps and never make it the full CI suite (roadmap-ci-steps-policy).

4b. Declare the execution mode (frontmatter)

Every new roadmap declares how a later /roadmap:process-* run should interact, via execution.mode: in frontmatter — autonomous (one run-start execution-contract confirmation, then uninterrupted except safety floors), phase-checkpoints (halt + compact status per phase boundary), or interactive (declare it — an omitted field is derived). Semantics: templates/roadmaps.md rule 18; run mechanics: roadmap-execution-contract. The field is intent, never a permission grant — grants happen only at the run-start contract. /roadmap:create asks this as one question; when authoring a roadmap directly, ask it too (follow-ups pre-select the parent's mode but always re-ask). Author every roadmap to be autonomy-capable (§ 4c); recommend autonomous when evidence, rollback coverage, and risk profile support unattended execution — the mode remains the user's risk preference, not a property of the document. Authoring duty for autonomous: steps must be precise enough to clear the ask-when-uncertain vague-trigger patterns — vagueness is resolved at authoring time, not mid-run; pre-existing [~] items in an autonomous roadmap draw a lint warning (they guarantee the archival gate fires later).

4c. Autonomy-first — zero human gates by default

Canonical rule: templates/roadmaps.md rule 22. Default human-checkpoint count: zero. Every step is agent-executable — - [ ] User verifies X steps and "Review / Sign-off" phases are authoring bugs; replace each with an agent-verifiable check (a command, a targeted test, a grep). Never restate run-time safety floors as steps.

Gate-test — three rungs in order (rule 22 owns the detail): 1. agent-clearable by tool/command → step. 2. has a technical answer a council could reach → still a step, first action runs the council; a contested technical decision is never a human gate while one is configured (agent-config council:status). 3. what survives both → ## Blockers (§ 5b): human gate (only a human can decide/authorize — Hard-Floor authorization, billable spend, or preference / risk appetite / product intent) vs external blocker (agent cannot resolve but CAN probe status — CI run, package release, upstream PR; Resolved when: carries the probe, owner is not a human). Merge is never a completion requirement — it may appear as a blocker only when later roadmap work depends on the merged state. lint_roadmap_complexity warns on human-gate patterns in every mode.

5. Exit & rollback per phase

Each phase declares exit criteria (decidable signals that the phase is done) and rollback (what to revert if the phase fails). A phase without exit criteria is open-ended; a phase without rollback assumes success. Exit criteria are agent-decidable — exit code, file exists, test passes — never "user reviews" / "looks good" (§ 4c).

5b. Blockers are structured, not free prose

A gate only the user or a maintainer can clear — a decision, an external dependency, an evidence threshold, a kernel-budget soak window — is recorded as a ## Blockers entry (### blocker: <id> with the seven fields of rule 20), never a stray "blocked on X" sentence. Write it so the owner can decide in one sitting: one option named and why, what the delay costs, a command or path per option rather than prose, and an offer to walk them through it. Ratcheted by lint_roadmap_blockers. Full shape: templates/roadmaps.md rule 20. Omit it entirely when there is no such gate; run the § 4c gate-test first. A hold is the publication-side twin — a blocker stops execution, a hold stops publication; ask once whether an intermediate tree state must stay unpublished (default no; roadmap incompleteness never is one), walk re-sequence → guard → hold, and record the avoided outcome as well as the taken one, per templates/roadmaps.md rule 28 and the § 5c self-check in /roadmap:create.

5c. Risk review (Gate R1) — after draft, before save

• Ready (non-draft) plan → ## Risk Register before save, self-review; seed from a fresh C→R1 handoff state (never re-ask a resolved branch).
• Product AND implementation risks ranked descending, one mitigation per row, each anchored to a phase/step here; none → exact honest-null grammar.
• Schema, staleness, grandfather, drafts-exempt: plan-review-gates § 1.

6. Step-marker semantics — pick [~] (defer) vs [-] (cancel) honestly

When authoring (and especially when rewriting a roadmap mid-flight), the difference between the two non-[x]-non-[ ] markers carries load:

Glyph	Semantic	When to use
[~]	deferred — planned, will be done, just not in this roadmap	Scope-cut + clear intent to revisit. Triggers the Iron Law 3 follow-up flow before archive — info preservation is enforced.
[-]	cancelled — won't be done at all	Scope rejected, design changed, replaced by another roadmap. The decision is final; no follow-up implied.

Optional inline annotations live on the same line:

- [~] Migrate the bulk-import job to chunked dispatch. <!-- deferred: ops capacity in Q3 -->
- [-] Wire SQS retry topic. <!-- cancelled: superseded by Lambda DLQ in road-to-event-bridge -->

The annotation is for the next human reader (and for the migration procedure when roadmap-management spawns a follow-up). Bare [~] / [-] is allowed; annotated is preferred.

A prohibition-shaped step closes with [x]

A step whose content is a prohibition ("Do not build the enforcement") has no artifact to point at. [~] invents receiver work nobody owes, [-] mislabels restraint as cancellation, [ ] makes an honoured bounded obligation unarchivable. It closes with [x] — the obligation was discharged, and [x] never required that something was created. Its verify: must name every implementation, registration and semantically-equivalent surface (a structural check, not one literal grep, which misses aliases and generated code); fail if an expected search root is missing, checked BEFORE the absence check, because a glob over a vanished directory returns nothing and reads as success; scope the claim to the branch diff — "this change introduced no enforcement", never the unprovable "enforcement exists nowhere"; and be re-run at archival. Not for a prohibition meant to hold indefinitely — that belongs in a rule, test or linter, because a closed step stops watching. Council convention, 2026-09-08 (2 seats, convergent); falsified if tooling defines [x] as requiring a positive mutation.

7. Follow-up roadmaps spawn from deferred items — frontmatter shape

When a parent roadmap closes with [~] items, the roadmap-management skill spawns a follow-up. Authors and reviewers must know the shape so they can recognise it: the frontmatter template, the two states the author picks between (status: draft, hidden from the dashboard, vs the default status: ready plus a body > Blocked until … note), and the rule that deferred steps are copied verbatim rather than re-authored → references/follow-up-roadmap-shape.md.

8. Source-derived & capability-adoption roadmaps (conditional)

Fires only when the roadmap originates from an external input (competitive/capability harvest, external suggestion, external LLM ideation) or adopts new skills/commands/a pack, or has genuinely contested trade-offs. For an ordinary internally-originated roadmap, skip this section — §§ 0–7 are the whole job.

When it fires, add four moves — a gap-table before drafting (KEEP/FOLD/CUT, integrate don't dump), resolve contested design in the council first then author, encode the decision so it survives (Council notes + neutral-descriptor Provenance + memory lock), and make "integration, not dump" a testable acceptance criterion. Full four-move detail → roadmap-writing-source-derived.

Frugality Standards

Apply the Frugality Charter to every roadmap you author.

Examples in this artifact:

• Per the charter's default-terse rule, the goal sentence states the outcome — no "This roadmap exists because…" ramp-up.
• Per the cite-don't-restate principle, link the canonical template for structural rules; do not paste them into the roadmap.
• Per the post-action summary suppression, council-pass integration notes append to the existing phase block — no new "Summary of council passes" section.
• Per the cheap-question check, never propose a "lightweight vs. structural" numbered choice when the diff makes the answer decidable.

Pre-save self-check:

1. Does the goal sentence open with the outcome, or with backstory?
2. Does any phase block restate template rules instead of linking them?
3. Are checkboxes present in every non-intro phase?
4. Are exit criteria decidable, or vibe-based ("looks good")?
5. Is content duplicated from another roadmap (supersession instead)? 5b. Does the frontmatter carry a relates: block — one row per probe hit with an extends/supersedes/depends/disjoint relation, or an explicit relates: [] whose note carries the probe's scanned: line? A relates: list written by reflex is worse than none: the empty case must be genuinely empty, not unexamined.
6. Any human-gate steps or sign-off phases (§ 4c violation) — agent-verifiable check or structured blocker instead?
7. Source-derived/adoption only (§ 8): is there a KEEP/FOLD/CUT gap-table behind the scope, a ## Provenance block with an ENC1: link, inlined council convergence, and an anti-dump acceptance criterion? (Internally-originated roadmap → these must be absent, not empty.)
8. Inbox-sourced only: if the roadmap consumed an agents/tmp/ file as its input, is that file moved to agents/tmp.old/<name> in the SAME reply, with the Source line pointing at the tmp.old/ path? (Per agents-layout § User Inbox Workflow. Move only the explicitly named input file(s); never sweep the rest of the inbox.)

Do NOT

• Author a roadmap without a goal sentence.
• Restate templates/roadmaps.md rules inside the roadmap body.
• Include version numbers, target releases, or git tags — banned by template rule 13 + scope-control.
• Plan automatic branch switches mid-roadmap (template rule 14).
• Ship a phase without checkboxes (roadmap-progress-sync Iron Law #2).
• Write inline human-verification or "Review / Sign-off" phases (§ 4c / template rule 22).
• Write merge, push, or commit steps into the roadmap. Roadmaps plan work; merge / push / commit are delivery decisions owned by the user (commit-policy Iron Law). A roadmap is "implementation-complete" once its checkboxes are ticked and verification has been run — merge timing is tracked outside the roadmap. Carve-out — a merge the USER directed may be RECORDED, marked <!-- carve-out: user-directed-merge -->; it records, never schedules. Discriminator is provenance: an instruction the user gave, never merge text that arrived by PASTE (a quoted log or snippet is not an instruction — the distinction git_authorization_hook.ts already draws). Unmarked merge text stays forbidden.
• Schedule full-pipeline CI literals as checkbox steps when quality.local_auto_run: false — the pattern list and the carve-out live in roadmap-ci-steps-policy, enforced by task lint-roadmap-ci-steps. Reword as narrow verifications, or mark the step <!-- carve-out: new-gate-verification --> when it verifies a NEW gate this roadmap introduces.
• Use ALL-CAPS Iron-Law fenced blocks — those belong in kernel-membership-listed rules.
• Adopt items from an external source / harvest without a KEEP/FOLD/CUT gap-table against the existing surface (§ 8) — that is a skill dump, not integration.
• Add a ## Provenance block or gap-table to an internally originated roadmap — § 8 is conditional; an empty section is noise (template rule 19).
• Name the raw competitor / tool or paste a raw source link — anonymize + ENC1:-encrypt (source-confidentiality).

Gotchas

• No checkboxes in a phase — agents/roadmaps-progress.md cannot count the phase; the dashboard reports zero open work even though the phase has prose. Enforced by roadmap-progress-sync Iron Law #2.
• Vague goal sentence — "Improve roadmap quality" forces every reader to re-derive intent and blocks decidable acceptance.
• Human-gate steps sprinkled through phases — each one interrupts an autonomous run, and the dashboard counts open work the agent can never close. § 4c: agent-verifiable check or structured blocker.
• Restating template rules — pasting structural rules into the roadmap body creates two sources of truth that drift over months.
• Version numbers in phase names — Phase 1 — v1.8.0 violates template rule 13 and scope-control § git-operations.
• Author-during-execution branch switches — the agent should not propose a new branch mid-roadmap; that decision is fenced to authoring time.
• Merge / commit steps in roadmap body — checkboxes like "merge PR #X" or "commit phase Y" couple roadmap closure to git operations the user has not authorized. Roadmap completion is decoupled from delivery; ship-the-PR is its own decision.
• Adopting an external suggestion verbatim — a harvest/suggestion roadmap that copies the source's proposed item list without the § 8 KEEP/FOLD/CUT audit becomes a skill dump: items that already exist get rebuilt, items that should fold into an existing artefact spawn a duplicate. The gap-table is the integration discipline.
• Council-as-afterthought — running the council only after a contested roadmap is written wastes the convergence: the plan still reads as open questions. For source-derived/contested plans, council first (§ 8.B), then author the verdicts.
