beacon-framework 0.8.0

Light-touch, pragmatic, artifact-driven framework for AI-assisted software delivery

BEACON

Light-touch, pragmatic, artifact-driven framework for AI-assisted software delivery.

"Would I proudly sign my name to this?"

BEACON owns the Product side of delivery — strategy, epics, ADRs, lifecycle discipline. It composes with SpecKit for the Engineering side — per-feature specs, plans, tasks. Each is independently installable; neither writes into the other's files. Active work is discovered from git, not stored — so parallel agents in worktrees never merge-conflict on a central state file.

quarter scope    Roadmap/README.md             ← strategy (BEACON)
weeks scope      Roadmap/epics/<slug>.md       ← initiative (BEACON)
days scope       specs/<NNN-slug>/             ← feature (SpecKit)
hours scope      specs/<NNN-slug>/tasks.md     ← tasks (SpecKit)
seconds scope    git branch + tasks.md state   ← active work (discovered)

Install

For humans

uvx --from git+https://github.com/darth-veitcher/beacon beacon init --here

Idempotent — re-running is safe. User-seeded files are preserved.

For the full installation walkthrough (including SpecKit setup), see AGENTS.md. It works equally well as a human read.

For LLM agents

Fetch the agent guide and follow it:

curl -s https://raw.githubusercontent.com/darth-veitcher/beacon/main/AGENTS.md

AGENTS.md is self-contained: vocabulary, install order (SpecKit then BEACON), workflow end-to-end, command reference, and what to do next on a fresh project.

Concepts

Five terms cover everything:

• Epic — a weeks-scope initiative at project-management/Roadmap/epics/<slug>.md. Groups one or more specs. Creating or editing an epic is a BEACON DESIGN-phase activity — produces cross-spec ADRs that no single feature spec.md can capture.
• Spec — a SpecKit feature folder at specs/<NNN-slug>/. SpecKit owns it. BEACON writes one file inside: .beacon.toml, the epic backlink.
• Bullet — the active piece of work in the current git worktree. Discovered live by resolving the current branch.
• ADR — a Markdown decision record at project-management/ADRs/ADR-NNN-<slug>.md (MADR format).
• Phase — SEED → DESIGN → BUILD → SHIP. Lifecycle gates surfaced as Claude Code skills.

Commands

Project lifecycle

beacon init [--here] [--language python|node] [--ai claude]   # install (idempotent)
beacon upgrade [--here]                                       # refresh framework files
beacon check [--here]                                         # files-present validation
beacon doctor [--here] [--strict]                             # semantic health check (15 checks)
beacon --version  /  beacon -V                                # show installed version

SEED phase (project bootstrap)

beacon seed                                  # status of the four SEED deliverables
beacon seed --strict                         # CI mode — WARN becomes FAIL
beacon seed scaffold                         # conversational fill-in from the terminal

Inside Claude Code, /beacon.seed runs an inferential scaffold — one or two broad questions, then Claude infers values for every template slot, presents them back plan-mode style, and writes the files on confirmation.

Epics (Product)

beacon epic new <slug> --title "<title>"          # create from template
beacon epic list [--detailed]                     # active epics + owned-spec rollup
beacon epic refresh <slug>                        # recompute spec rollup (read-only)
beacon epic finish <slug>                         # archive; refuses while specs in flight

Bullets (Engineering, per worktree)

beacon bullet start [<title>] [--epic <slug>]     # start current worktree's bullet
beacon bullet finish                              # mark done
beacon bullet status                              # show current bullet
beacon bullet list                                # all bullets across local branches, grouped by epic
beacon bullet sweep                               # delete orphan sidecars

Spec ↔ epic link

beacon link-spec <NNN-slug> --epic <slug>         # backlink an existing spec to an epic

Integrations

beacon integration list
beacon integration add <name>          # claude (default), release
beacon integration remove <name>

---

Languages

Quality-gate placeholders render per-language at install time:

beacon init --language node       # → bun run lint; bunx tsc --noEmit; …
beacon init --language python     # → uv run ruff; uv run ty check; …  (default)

Add a language by dropping a TOML at src/beacon/resources/languages/<name>.toml.

---

Integrations

beacon integration list shows what's available.

claude (installed by default)

Slash commands (/init, /git:*, /design:*) and the marker-delimited block in .claude/CLAUDE.md that briefs the agent on the lifecycle. If SpecKit is detected at install time, four additional wrappers ship at .claude/commands/beacon/:

Wrapper	Inlines (via @)	Adds before	Adds after
/beacon.specify <epic-slug> <feature>	SpecKit's specify	Epic Success criteria, Non-goals, ADRs	beacon link-spec <NNN-slug> --epic <slug>
/beacon.plan	SpecKit's plan	(none)	Placeholder + ADR-reference sweep
/beacon.tasks	SpecKit's tasks	(none)	(hook in place; no-op today)
/beacon.implement	SpecKit's implement	(none)	beacon epic refresh <slug>; prompt to epic finish if all specs done

Wrappers compose with SpecKit's commands via Claude Code's @<path> inclusion — no prompt duplication, no maintenance burden when SpecKit updates. If SpecKit isn't installed, the wrappers are skipped (with a notice); installing SpecKit later and running beacon upgrade retro-wires them.

release (opt-in)

beacon integration add release

Drops three things into the project:

File	What it is
.github/workflows/release.yml	Branch-based release: push to main → PyPI, push to develop → TestPyPI (pre-release). Framework-owned.
PUBLISHING.md	One-time PyPI/TestPyPI Trusted Publisher registration steps. User-seeded — never overwritten.
[tool.semantic_release] block in pyproject.toml	python-semantic-release config wrapped in # ──── BEACON release integration ──── sentinels. Refuses to clobber an existing hand-authored block.

beacon integration remove release cleanly reverses — deletes the workflow + the fenced PSR block; leaves PUBLISHING.md alone.

Health checks

beacon check     # files-present validation against the manifest
beacon doctor    # semantic — 15 checks across content health, active-work integrity, Product↔Engineering drift
beacon doctor --strict   # CI mode — every WARN becomes FAIL

Doctor's 15 checks group into three concerns:

• Content health — placeholder text in 00-problem-statement.md, stale Work/sessions/, ADR coverage, framework files modified on disk.
• Active-work integrity — current worktree has a discoverable bullet, no orphan sidecars, spec branches have an active task in tasks.md.
• Product ↔ Engineering drift — every spec has an epic backlink, every backlink is reciprocated in the epic's ## Specs, active branches are tied to active epics, no ghost epics, no lifecycle mismatches, Roadmap reviewed in the last quarter.

Sample output on a project with one epic, one spec, and the problem statement still unfilled:

✗ problem-statement: Placeholder text still in problem statement: [Replace with
   your problem statement] …. Fill in 00-problem-statement.md before opening a
   feature branch.
✓ active-bullet: 001-oauth-login → T001 scaffold OAuth callback (owner: agent-A,
   source: spec)
✓ spec-task-alignment: Active task in 001-oauth-login: T001 — scaffold OAuth
   callback
✓ spec-backlink-integrity: All 1 spec folder(s) backlink an epic.
✓ epic-spec-listed: All spec→epic backlinks are reciprocated in epic files.
✓ epic-coverage: 001-oauth-login → epic user-auth
✓ ghost-epic: All 1 Active epic(s) have current work.
✓ epic-spec-lifecycle: Epic statuses match their owned-spec state.
! epic-adr-coverage: Active epic(s) with no ADRs listed: user-auth. …
! roadmap-staleness: Roadmap/README.md has no `Last reviewed: YYYY-MM-DD` header.
✓ sessions: No stale session files.
✓ adr-coverage: 0 ADR(s) on file across 5 commits.
✓ drift: Framework files match shipped resources.

ok=10  warn=2  fail=1

A FAIL exits non-zero (--strict does the same for WARN), so it wires cleanly into a pre-commit hook or CI gate.

Framework files are overwritten on beacon upgrade. Seeded files are written only when absent. The manifest is the contract.

Atomicity

• BEACON imports nothing from SpecKit. No build-time dependency.
• beacon init succeeds on projects with no SpecKit installed; the four /beacon.* wrappers are skipped with a notice. beacon upgrade retro-wires them once SpecKit appears.
• beacon bullet *, beacon epic *, beacon link-spec, beacon doctor all work without SpecKit anywhere on the system. Doctor's spec-aware checks no-op when no spec folders exist.
• BEACON writes nothing into .specify/. SpecKit writes nothing into project-management/. The only file inside specs/<slug>/ BEACON owns is .beacon.toml — SpecKit ignores it.
• Install, upgrade, and remove either framework independently.

---

Migration from BEACON ≤ 0.5

The previous "single Roadmap god-file" model (one Roadmap/README.md with ## Active Bullet lines) doesn't scale to parallel agents. v0.6 replaces it with:

• Roadmap/README.md — strategy only (quarter scope)
• Roadmap/epics/<slug>.md — per-initiative files (weeks scope)
• Per-worktree branches — active state discovered live, not stored

beacon upgrade detects the legacy shape and drops a Roadmap/MIGRATION_v0.6.md breadcrumb non-destructively. Your previous content stays in place; the new template is installed alongside. Follow the migration note to slot in-flight work into the new model.

Phase guides also migrated: project-management/Prompts/0N-PHASE.md (≤ 0.3) → .claude/skills/beacon-*/SKILL.md. beacon upgrade removes the legacy directory automatically.
