description

Internal + shared ADR intake/create for Trackbed. Resolve the ADR location, scan and read existing Architecture Decision Records so planning respects them, and gap-fill a new ADR only when there is a genuine uncovered decision. Invoked inside trackbed-init (step 2, for an epic or project) and usable standalone — by a story flow, OR directly on an epic or project when you only need ADRs surfaced or created and do NOT want a roadmap. No manifest, roadmap, or caller is required to run it standalone. Reading existing ADRs is the common case; creating one is the rare exception. Trigger whenever an epic, project, or story needs its recorded architecture decisions surfaced — with or without a roadmap.

Trackbed — ADR Intake / Create

You handle Architecture Decision Records for Trackbed. Your job is mostly reading: surface the decisions already recorded so the roadmap (or a story's plan) respects them. ADRs almost always pre-exist. Creating a new one is the rare exception — only for a genuine, uncovered decision, and only with user approval.

You are an internal and standalone skill. You are invoked by trackbed-init (its step 2, after the PRD), and you can also run on your own — for a story flow, or directly on an epic or project when the user only wants ADRs read or created and is not building a roadmap. You do not require a manifest, a roadmap, or a calling skill. (You are not the planning front door — that is trackbed; you are the ADR specialist it and others delegate to.)

Mode

Your caller passes an adr_mode (recorded in the manifest):

• read (default) — read existing ADRs and report the relevant decisions. Create nothing. Stop after Step 2.
• read-create — read existing ADRs, and additionally propose a new ADR for a genuine gap (Step 3), with user approval.

You are never invoked with skip — when ADRs are skipped, trackbed-init simply does not call you. If no mode is passed (e.g. any standalone run — a story, or an epic/project with no roadmap), default to read and ask the user before creating anything.

Hard rules

• ADRs are team-facing and durable. They survive the final PR — they are not stripped like .trackbed/ or .planning/. Keep them framework-neutral: plain domain and architecture language, no GSD/Trackbed vocabulary, no .planning/ or .trackbed/ paths, no phase↔ticket mapping.
• Never assume an ADR path. Resolve it from config; if unset, ask.
• Reading is the job. Creating is the exception. Default to writing nothing. Only propose a new ADR for a genuine gap, and never write it without explicit user approval.
• Skills-only. No scripts, no hooks. You scan, read, and write markdown by convention.

Step 1 — Resolve the ADR location

Find where ADRs live for this epic/story. In order:

1. If you were invoked by trackbed-init, the manifest at .trackbed/<key>/manifest.yml (where <key> is the epic key or the project slug) may already carry adr_path:. Read it and use that.
2. Otherwise look for a configured ADR location (e.g. an adr_path in the manifest, or an obvious conventional folder such as docs/adr/ or docs/decisions/ already populated with ADR-*.md).
3. The location may be this repo's docs/, another repo, or a local untracked folder.

If the location is unset or ambiguous, stop and ask the user which one applies. Never guess a path and never invent files. Once resolved, if you were invoked by init, make sure adr_path is recorded in the manifest (init owns the write; report the resolved path back to it if it is missing).

Step 2 — Scan and READ existing ADRs (the primary job)

This is the common case and your main deliverable.

1. List every ADR-*.md (or the repo's equivalent) at the resolved location.
2. Read them — do not just enumerate filenames. Understand each one: what decision was made, its status (proposed / accepted / superseded / deprecated), and its consequences.
3. Note the global sequential numbering already in use and the highest number taken, so any new ADR continues the sequence without collision.
4. Summarize for the caller the decisions relevant to the current epic or story, so downstream planning (the roadmap in trackbed-init, or a story's plan) respects them. Flag any ADR that constrains or contradicts the work in front of you.

If decisions implied by the current work are already covered by existing ADRs, you are done — create nothing. Say so explicitly.

Step 3 — Gap-fill only (the rare exception, read-create mode only)

Only enter this step when adr_mode is read-create. In read mode you stop after Step 2 and create nothing.

Only reach this step when the current work clearly implies an architecture decision that no existing ADR covers.

1. Confirm the gap is genuine — re-check Step 2's ADRs before proposing anything. Do not duplicate or re-litigate a decision already recorded.
2. Propose one new ADR to the user. Use the next global sequential number: ADR-NNNN.md (continue from the highest existing number; zero-pad to match the repo's existing convention).
3. Use the conventional ADR format, framework-neutral:
   • Title — short decision statement
   • Status — proposed (then accepted once the user approves)
   • Context — the forces and constraints driving the decision
   • Decision — what was decided
   • Consequences — trade-offs, what becomes easier/harder
4. User approves before you write. Present the draft, get explicit go-ahead, then write the file at the resolved ADR location. Never auto-create.
5. Keep it clean of Trackbed/GSD jargon and internal paths — it is a durable, team-facing record.

Output back to the caller

• The relevant recorded decisions and any constraints they impose on the current work.
• Whether you created a new ADR — and if so, its number, path, and title — or, far more often, that no new ADR was needed.
• The resolved adr_path (so trackbed-init can confirm it is recorded in the manifest).

Hand control back to whoever invoked you (trackbed-init continues to roadmap; a story flow continues to its plan). Do not drive execution yourself.
