description

bstack — the Broomva Stack. Twenty irreducible primitives (P1-P20) plus 30 curated skills that turn an agent-driven workspace into a self-operating system. Each primitive closes one specific failure mode (session amnesia, destructive ops, invisible work, dirty-tree drift, context rot, ritual phrases without substance, single-model echo chambers). The canonical operating mode is broomva/autonomous (fires every reflex without prompting). Use when: (1) bootstrapping a new agent-driven workspace, (2) verifying primitive compliance via 'bstack doctor', (3) repairing missing governance/hooks/policy via 'bstack repair', (4) listing installed-vs-missing skills via 'bstack status', (5) validating skill frontmatter health via 'bstack validate', (6) full reconfiguration via 'bstack revamp'. Triggers on 'bstack', 'broomva stack', 'bootstrap project', 'install all skills', 'P1' through 'P20', 'agent harness', 'self-operating workspace'.

bstack — The Broomva Stack

Twenty irreducible primitives. Thirty curated skills. One canonical operating mode. One self-operating workspace.

bstack is a portable harness metalayer — it composes existing skills into a binding primitive contract that the agent enforces by reasoning, the doctor enforces by checking, the bootstrap enforces by scaffolding, and the canonical operating mode (broomva/autonomous) enforces in execution.

Substrate vs Mode

bstack ships two complementary layers:

• Substrate (this skill, /bstack): the 20 primitives + 30 skills + governance + hooks + .control/policy.yaml. This is what /bstack bootstrap installs. The substrate is the capability — what's available in the workspace.
• Mode (broomva/autonomous): the canonical behavior that runs on top of the substrate. When the user says "go" / "proceed" / "be autonomous", /autonomous fires the 20-reflex pipeline that uses every primitive in sequence.

Installing the substrate without the mode = the workspace has primitives but no entry point to engage them. Invoking the mode without the substrate = wishful thinking. Compounded: /bstack bootstrap installs the substrate, then /autonomous is the standing operating mode for substantive work units.

Bootstrap itself is two-flow — a deterministic structured scaffold (the floor) plus an agent-authored generative tailoring pass (the bespoke layer). See Two-flow workspace setup.

Quick start

Install:

npx skills add broomva/bstack

Then, in your agent session:

/bstack bootstrap     → install 30 skills + scaffold governance + wire hooks + run doctor
/bstack doctor        → verify primitive contract compliance (always exits 0)
/bstack repair        → fix specific gaps surfaced by doctor (asks before writing)
/bstack status        → show which skills are installed vs missing
/bstack validate      → check skill SKILL.md frontmatter health
/bstack revamp        → full reconfiguration (force-reinstall + rewire + re-doctor)
/bstack wave dispatch <plan...>   → atomic parallel-agent dispatch from N plan files
/bstack wave status <wave-id>     → forensic per-wave state table
/bstack wave list                 → all waves with summary state
/bstack bench run                 → two-phase skill-evolution benchmark (P11)
/bstack bench compare             → Phase 1 vs Phase 2 REPORT.md
/bstack bench tasks list          → registered task sets
/bstack bench run --runner live --provider databricks --model ...
                                  → real LLM via OpenAI-compatible provider (≥ 0.11.0)
/bstack workspace register        → add this workspace to ~/.broomva/global/registry.yaml (≥ 0.18.0)
/bstack workspace list            → list all registered workspaces (Federation, Phase 8)
/bstack workspace info            → is the current workspace registered?
/bstack workspace deregister      → remove a workspace by --name or --path
/bstack status --aggregate        → federation rollup: name × bstack_version × composite_ω × verdict
/bstack cross-review <pr> --repo <owner/name>
                                  → P20 cross-model adversarial review via remote
                                    git fetch (≥ 0.20.0, BRO-1227 Fix B)

What bstack enforces

The twenty primitives. Each closes one specific failure mode that drifts into entropy in unsupervised sessions:

#	Primitive	Closes
P1	Conversation Bridge	session amnesia
P2	Control Gate	destructive ops the model didn't authorize
P3	Linear Tickets	invisible work
P4	PR Pipeline	merging unreviewed code
P5	Parallel Agents	sequential bottleneck
P6	Knowledge Bookkeeping	knowledge graph rot
P7	Skill Freshness Check	silent rot of npx skills add snapshots
P8	Branch + Worktree Janitor	squash-merge accumulation
P9	CI Watcher + Productive Wait (broomva/p9 skill — name matches number)	sleep-on-wait dead time (CI, deploys, builds — PR CI is the reference impl)
P10	Worktree Hygiene Discipline	dirty-tree drift across the PR lifecycle
P11	Empirical Feedback Loop	shipping code that compiles but doesn't work
P12	Persistent Loop Discipline (broomva/persist skill)	long-horizon work decaying as the context window rots
P13	Dream Cycle Discipline	tier-crossing consolidation corrupting upper-tier rules without replay (the shadow dream failure mode)
P14	Dependency-Chain Reasoning Discipline	"think deeply through chain of dependencies" becoming a ritual phrase without concrete upstream/downstream enumeration
P15	State-Snapshot Before Action	plans built on stale state (uncommitted work, in-flight PRs, stale deploys)
P16	Crystallization Discipline (the Bstack Engine)	recurring valuable patterns living only in the user's head — never promoted to skill/primitive/policy infrastructure
P17	Lens-Routed Request Articulation (broomva/role-x skill, planned)	flat-dispatch fan-out failing to load domain context; agents performing tasks without the typed lens (legal review vs design vs research) that shapes the correct quality_bar
P18	Format-Follows-Audience Discipline	markdown-by-default for everything regardless of audience; long specs nobody reads; ASCII pseudo-diagrams + unicode-color-approximation when SVG-in-HTML is the correct primitive
P19	Orchestration-Mechanism Selection Discipline	implicit between-reflex handoffs ("continue please"); using wrong mechanism for work shape (/goal on >1h work, persist on 30-min task, /loop on event wait); the autonomous arc broken by missing-mechanism failure
P20	Cross-Model Adversarial Review Gate (broomva/cross-review skill)	same-model echo chamber; writer self-validates own work; AI slop (over-engineered abstractions, template-paste, unnecessary wrappers) merged because no different evaluator scored ≥7/10

Primitive operationalization references (loaded on demand by the agent applying the primitive):

• Empirical (P11) — dogfood patterns cookbook: references/dogfood-patterns.md. Per-tech-stack interaction surfaces matrix (Tauri+sidecar / Next.js / Expo RN / Rust CLI / REST API / MCP server). Names the skill toolkit (Interceptor mandatory for visual deploy verification; gstack / cliclick / screencapture / curl+jq compose per stack), the canonical arc per stack, the gotchas, the Dogfood Plan contract, and the receipt template. bstack doctor §13 enforces stack-keyed plan presence (informational until rule-of-three).

Roadmap to v1.0.0 — the architectural contracts, gap catalog, and 9-phase closure plan from v0.3.1 onwards live in specs/2026-05-18-substrate-completion.md (canonical) and references/substrate-completion-overview.md (agent-readable summary). Every future bstack release through v1.0.0 references this spec for "what does done look like".

Naming convention for agent prose (binding on every agent)

Each primitive carries a short name for use in agent prose. When referencing a primitive in responses, PR bodies, commit messages, code comments, knowledge-graph entries, or any human-readable surface, use the Name (Pn) form — "applying Snapshot (P15)", "via Dep-Chain (P14)", "running Bookkeeping (P6)" — not bare P15 / P14 / P6. The number is the canonical identifier (stable across renames); the name is the human-readable handle. First mention in a response uses the full form; subsequent mentions in the same response may drop to bare Name ("Snapshot showed clean state") but never to bare Pn. Anchors, section IDs (#p15-state-snapshot-before-action), and primitive-count headers ("Twenty irreducible primitives") stay numeric — URL stability and arithmetic respectively. Failure mode: bare Pn makes responses read as numeric soup; cross-session readers can't decode the reference without a lookup. The Short-name index below is the recall key.

Short-name index (canonical numbering): Bridge (P1) · Gate (P2) · Tickets (P3) · Pipeline (P4) · Fanout (P5) · Bookkeeping (P6) · Freshness (P7) · Janitor (P8) · Wait (P9) · Hygiene (P10) · Empirical (P11) · Persist (P12) · Dream (P13) · Dep-Chain (P14) · Snapshot (P15) · Crystallize (P16) · Lens (P17) · Audience (P18) · Orchestrate (P19) · Cross-Review (P20).

Canonical statement lives in workspace CLAUDE.md §Bstack Core Automation Primitives and workspace AGENTS.md near line 93. This SKILL.md restates the rule so it's visible at the entry point where /bstack loads.

Skill-name ↔ primitive-number alignment: when a skill repo carries a numeric name (e.g., broomva/p9 for Wait at P9), the primitive numbering commits to keeping that number stable — renaming a skill repo would break every npx skills add broomva/p9 install. Skill repos with functional names (broomva/bookkeeping = P6, broomva/persist = P12) take their name from the function, not the number.

bstack wave (new in this version). Fills the N>1 × across-session × external-trigger cell of Orchestrate (P19)'s mechanism cube. Use it when you have N independent plan files that can run in parallel without shared mutable file writes (Fanout (P5)). Each plan's frontmatter declares its worktree and branch; the wrapper validates atomically, creates worktrees, and launches one claude --bg per plan. State lives in ~/.cache/bstack/wave/<wave-id>/ (Persist (P12) filesystem-as-state). See the design at docs/superpowers/specs/2026-05-13-bstack-wave-design.md (workspace repo) for the full primitive coalescence map.

Canonical operating mode: broomva/autonomous — when the user says "go" / "proceed" / "be autonomous" / "automerge" / any bare execution directive, /autonomous fires the 20-reflex pipeline that exercises every primitive above in the right sequence. Substrate without mode is dormant; mode without substrate is wishful. Compounded, they produce a self-operating workspace.

After skill check, run the harness validation:

cd ~/broomva && make bstack-check 2>&1

Report results. If any checks fail, fix them before proceeding.

Onboarding (first-time setup wizard)

When the preamble reports ONBOARDING: bstack not yet initialized, run the guided wizard. There are two paths — same underlying script (scripts/onboard.sh), different drivers.

Path A: In Claude Code (agent-driven via AskUserQuestion)

When in a Claude Code session, the agent collects the 4 wizard inputs through AskUserQuestion calls (so the user answers in chat), then invokes scripts/onboard.sh with the collected flags. No read -r prompts in the user's terminal — the agent IS the input mechanism.

The 4 questions (with defaults shown to the user):

1. Workspace path — $HOME/broomva (default). Where bstack scaffolds governance files.
2. Profile — personal / enterprise / autonomous-strict. Determines gate strictness:
   • personal — relaxed; solo dev / experimentation
   • enterprise — strict, audit-friendly
   • autonomous-strict — gates-are-trust principle; L3 auto-merge enabled (requires G-L3-* gates in CI)
3. Life Agent OS integration — install / skip. Whether to also install life-os + arcan binaries.
4. Auto-merge policy for governance paths — human-required / trust-gates:
   • human-required — safe default until G-L3-1/G-L3-2 are wired into CI
   • trust-gates — L3 paths auto-merge when L3 trust gates pass

After collecting the four answers, the agent invokes:

bash "$_BSTACK_ROOT/scripts/onboard.sh" \
  --workspace="$A1" \
  --profile="$A2" \
  --life="$A3" \
  --auto-merge="$A4" \
  --skip-prompts

The script persists choices to ~/.bstack/config.yaml via bin/bstack-config, runs scripts/bootstrap.sh against the chosen workspace, and writes the init marker at ~/.config/broomva/bstack/initialized. The agent then reports the onboarding receipt (workspace + profile + life + auto-merge + bootstrap status) to the user and recommends /autonomous as the next move.

If AskUserQuestion is unavailable (running outside Claude Code): fall through to Path B.

Path B: In a shell (interactive read -r prompts)

bash $_BSTACK_ROOT/scripts/onboard.sh

The script prompts for the same 4 questions via read -r. Same downstream effect: config persisted, bootstrap run, marker written.

Idempotency + re-running

• Once ~/.config/broomva/bstack/initialized exists, subsequent onboard.sh invocations exit 0 immediately (no prompts, no bootstrap).
• Re-run with --force to redo the wizard.
• Run --dry-run to preview choices without persisting.

Receipt schema (the marker file)

The init marker is a YAML-style flat file at ~/.config/broomva/bstack/initialized:

# bstack initialization marker
onboarded_at: 2026-05-12T22:49:44Z
workspace: /Users/foo/broomva
profile: personal
life: skip
auto_merge: human-required
bstack_repo: /Users/foo/.agents/skills/bstack
bootstrap_status: ok           # ok | failed | skipped

Future sessions inspect this for state. bootstrap_status: failed is captured transparently — the user knows bootstrap needs follow-up without losing the wizard answers.

Commands

bootstrap — full install + system wire-up

scripts/bootstrap.sh is the install/wire path. It:

1. Installs all 30 skills via npx skills add broomva/<skill> — broomva/autonomous is the first in the roster (canonical operating mode)
2. Scaffolds missing governance files from assets/templates/:
   • CLAUDE.md (workspace invariants + RCS hierarchy + primitive table P1–P20 + §Ritual vs Substance)
   • AGENTS.md (operational rules + per-primitive sections + reflexive triggers for all reasoning-enforced primitives)
   • .control/policy.yaml (ci_watch / ci_heal / auto_merge / gates G1–G11)
   • .claude/settings.json (P1, P2, P7 hook wiring)
3. Adds make targets to existing Makefile (or creates one): bstack-check, control-audit, janitor, bstack-primitive-lint (G-L3-1), bstack-rule-of-three (G-L3-2), bstack-l3-trust (combined L3 gates)
4. Installs pre-commit hook (.githooks/pre-commit) via git config core.hooksPath .githooks
5. Runs bstack doctor to verify primitive contract compliance + make bstack-l3-trust to verify L3 gates pass
6. Reports a bootstrap receipt — what was installed, what was scaffolded, what was already present
7. Recommends invoking /autonomous for the user's next substantive work unit — the substrate is installed; the canonical mode is ready to engage

Idempotent: never overwrites existing user customizations. If a file already exists, the bootstrap appends only the missing primitive sections / blocks / hooks, never the whole file.

Self-application: when /bstack bootstrap is invoked in an existing workspace, the bootstrap itself runs under /autonomous discipline — state snapshot, dep-chain trace, validation plan, PR pipeline. The bootstrap that installs the discipline embodies the contract it ships.

Two-flow: bootstrap is not a single deterministic pass. The structured scaffold above is the floor; the agent then runs a generative tailoring pass on top of it. See Two-flow workspace setup below for the full model and canonical sequence.

Two-flow workspace setup (structured + generative)

bstack bootstrap is a two-flow operation, not a single deterministic pass. This mirrors the Audience (P18) split bstack already applies to documents — a deterministic Category-B projection floor plus a context-aware Category-C bespoke authoring layer — now applied to workspace setup itself.

bstack bootstrap  =  STRUCTURED flow      →   GENERATIVE flow            →   VERIFY
                     (deterministic, no LLM)    (agent-authored, contextual)   (deterministic)
                     scripts + templates        tailoring of THIS workspace    bstack doctor
                     + shipped+deployed hooks
                     + gates + .control

1. Structured flow (the floor — reproducible, no LLM). bstack bootstrap runs the idempotent scaffold: installs skills; scaffolds governance from assets/templates/* (CLAUDE.md, AGENTS.md, METALAYER.md, .control/policy.yaml, .control/arcs.yaml, .control/rcs-parameters.toml, schemas/); deploys the hook scripts into the workspace (control-gate / skill-freshness / conversation-bridge / knowledge-catalog-refresh + the L0/L1 audit hooks); wires .claude/settings.json; installs the L3 rate gate + CI gate. This flow must be COMPLETE and CORRECT — every wired hook must have a backing script deployed (no dangling references). It is the lossless baseline: same inputs → same workspace, every time.

2. Generative flow (the bespoke layer — agent-authored, to-the-ceiling). After the structured scaffold, the agent does a context-aware pass that templates cannot produce. Concretely the agent:

a. Detects the stack + project intent — signals: language/build files, existing code, README, the user's stated goal. b. Tailors the scaffolded governance prose to THIS project — rewrites the generic CLAUDE.md / AGENTS.md placeholders into project-specific invariants, conventions, and architecture notes (not generic template text). c. Authors a project-specific CI workflow — the structured flow ships the L3-stability gate; the agent generates the test/lint/build job that matches the detected stack. d. Fills the Dogfood Plan (Empirical, P11) with the real entry surfaces + evidence anchors for this project's stack (per references/dogfood-patterns.md). e. For RCS/RSI or control-systems repos — optionally lays down a runnable L0–L3 substrate + a HIERARCHY/instantiation map, so the workspace doesn't merely DESCRIBE a control system, it RUNS one. For ordinary repos, this step is skipped. f. Files the initial knowledge-graph entities / decision log (Bookkeeping, P6) for the new workspace — proactively, never asking permission.

3. Verify (deterministic). bstack doctor gates BOTH flows: the structured contract (governance files, hooks wired+deployed, gates, schemas) AND the generative output (the doctor surfaces gaps if the agent's tailoring left a hole). Generative output is always checked by the structured contract — never trusted blind.

Key principles:

• This mirrors the established Audience (P18) discipline: the STRUCTURED flow is the Category-B projection floor (deterministic, lossless, reproducible); the GENERATIVE flow is Category-C bespoke authoring (context-aware, to-the-ceiling). The same structured-vs-generative split bstack already applies to documents, now applied to workspace setup.
• The structured flow must never wire a hook whose script isn't deployed — the dangling-hook failure mode this work fixes. "Wired but dangling" is forbidden: every hook reference resolves to a real, executable, deployed script.
• The agent runs structured FIRST (idempotent floor), THEN generative (bespoke), THEN doctor (verify). Never generative-without-structured (no floor) or structured-without-generative (generic, untailored workspace).

doctor — verify primitive contract

scripts/doctor.sh. Eight check sections:

1. Governance files exist (CLAUDE.md, AGENTS.md, .control/policy.yaml)
2. CLAUDE.md primitives table has all P1–P20 rows + correct count header ("Twenty irreducible…")
3. AGENTS.md has each primitive section (### P1: or ### P1 — Short: Long format through ### P20)
4. Reflexive Trigger Rules present for P6, P9, P10, P11, P12, P13, P14, P15, P16, P17, P18, P19, P20 (the reasoning-enforced primitives)
5. .control/policy.yaml has required blocks (ci_watch:, ci_heal:, auto_merge:)
6. .claude/settings.json wires the expected hook scripts (P1, P2, P7)
7. Each primitive's mechanism is reachable on disk
8. L3 trust gates pass — runs make bstack-l3-trust if the target exists; reports G-L3-1 + G-L3-2 results; surfaces any structural/ rule-of-three violations as gaps

Modes: default (full report), --quiet (only gaps), --strict (exit 1 on gap, for CI lanes). Always exits 0 by default. Each gap includes an actionable → fix: hint.

bootstrap invokes doctor --quiet automatically as its final step. The L3 trust gate (check 8) is the substrate-level equivalent of the new mode's anti-rationalization layer — both close the failure mode where governance evolves without machine-checkable evidence behind it.

repair — apply targeted fixes

scripts/repair.sh. Reads the doctor's gap list, asks the user before each fix, then applies the specific repair (add missing primitive section from template, add missing policy block, wire missing hook). Idempotent. Never destructive.

status — installed vs missing + harness health

Re-run the preamble. For each skill show: name, layer, installed/missing. Then run make bstack-check and report harness health.

validate — skill frontmatter health

scripts/validate.sh. Verifies each skill has a valid SKILL.md with proper frontmatter. Then runs the full bstack-check harness validation.

revamp — full agent reconfiguration

scripts/revamp.sh. Triggers complete workspace reconfiguration:

1. Reinstall all 30 skills (force mode)
2. Regenerate governance files from templates (asks before overwriting)
3. Rewire hooks (git pre-commit + Claude Code Stop/Notification/PreToolUse/SessionStart)
4. Force-run conversation bridge across all projects
5. Run full control audit
6. Update AGENTS.md with current state

workspace — multi-workspace federation registry (≥ 0.18.0, Phase 8)

bin/bstack-workspace + scripts/workspace.py. Maintains the host-level roster at ~/.broomva/global/registry.yaml of bstack-governed workspaces on this machine. Federation is opt-in and read-only — each workspace remains the source of truth for its own state. The registry is the index bstack status --aggregate walks to rollup composite-ω health.

bstack workspace register             # registers $PWD (name = basename)
bstack workspace register --path ~/projects/foo --tag client-x
bstack workspace list --json          # machine-readable for scripts
bstack workspace info                 # is this workspace registered?
bstack workspace deregister --name foo

Exit codes: 0 ok, 2 invalid args, 3 schema/parse error, 4 target not found, 5 name conflict at different path. SLO: register/list p50 < 100ms.

Federation is not a new primitive — no P21. It composes existing primitives: Snapshot (P15) emits the per-workspace audit signal; the multi-layer composite-ω from v0.16.0 §19 feeds the per-workspace verdict. Doctor §20 surfaces registry health (informational unless the registry file's schema_version != 1).

Metalayer integration

bstack is the measurement substrate for the agentic-control-kernel. The harness records:

Metric	Target	How
Skills installed	28/28	preamble roster
Governance files	4/4	CLAUDE.md, AGENTS.md, METALAYER.md, .control/policy.yaml
Hooks wired	4/4	Stop, PreToolUse safety, PreToolUse regression, pre-commit
Status line	active	~/.claude/statusline-command.sh
Bridge operational	fresh < 24h	~/.cache/broomva-bridge-stamp mtime
Control audit	5/5 sections	make control-audit exit code
Conversations indexed	≥1 session	docs/conversations/Conversations.md exists
Primitive contract	20/20	bstack doctor exit code

When to use bstack

• Setting up a new project with Broomva conventions → bootstrap
• Validating an existing project meets the primitive contract → doctor
• Fixing a specific gap doctor reports → repair
• Checking skill freshness or roster completeness → status or validate
• Major workspace cleanup → revamp

Prompts as a shared knowledge surface

bstack treats the broomva.tech prompts library as a shared knowledge surface across agents, not a private repository. Two things every bstack workspace gets from it:

1. Reusable directives — versioned, parameterized prompts (code-review-agent, deep-research-agent, ai-native-platform-architect, bstack-control-harness-bootstrap, etc.) that any agent can pull and apply.
2. An evaluation engine — every pull and every completion writes a typed row to prompt_invocation. Source attribution (web|cli|skill|api), latency, tokens, cost, and explicit user feedback all flow into the eval surface at broomva.tech/api/metrics/*.

Reflexive rule (mandatory)

When the user asks for a known pattern (code review, deep research, platform redesign, harness bootstrap, etc.) AND the pattern exists in the library, reach for it instead of writing from scratch. The five-step mandate is non-negotiable:

# 1. Tag the session
export BROOMVA_SOURCE=skill

# 2. Pull — captures invocation_id on stderr
broomva prompts pull <slug> --json 2>&1 | tee /tmp/broomva-last.json

# 3. Use the prompt body as instructions for the work

# 4. MANDATORY after completing the work
broomva prompts complete <invocation_id> \
  --status completed --model <name> \
  --latency-ms <ms> --tokens-in <n> --tokens-out <m>

# 5. Optional — capture explicit user feedback
broomva prompts feedback <invocation_id> --slug <slug> --signal up --text "..."

Skipping step 4 means the row stays pulled and the eval engine can't learn from your run. The 24h sweeper eventually flips it to abandoned — a quality signal, not a useful run.

Discovery

broomva prompts list --metrics --sort skill_invokes   # most-invoked first
broomva prompts list --category agent-instructions    # filtered
broomva prompts get <slug> --raw                      # body only

Composition with the primitive contract

• P1 captures the invocation id in the conversation log — backpointer from the session to the eval engine.
• P4 ties PR-review prompt invocations to merge outcomes — measurable pass rates per prompt version.
• P6 promotes synthesis-worthy prompts to entity pages in research/entities/ (the library is the runtime registry; the knowledge graph is the crystallized form).
• P11 completing the invocation with real tokens_in/out, latency_ms, error_message is the same discipline as P11: validate with measurable outcomes.
• P13 the eval engine's evolving rankings are a dream-tier substrate; per-run telemetry is the dense lower-tier signal.

Self-evolution

When the agent improves a primitive, the workflow is:

1. Pattern observed across multiple sessions (L3 stability budget; rapid changes destabilize the system)
2. Captured in conversation log (Stop hook — automatic via P1)
3. Crystallized in AGENTS.md (one PR, deliberate)
4. Enforced in .control/policy.yaml if mechanically gateable (one PR, deliberate)
5. Doctor extended to check the new rule (one PR, deliberate)
6. Future agents inherit the improvement

This is the f₃ dynamics function at L3 of the RCS hierarchy. See references/primitives.md for the formal stability constraint.
