description

bstack P17 — Lens-Routed Request Articulation. The typed routing layer above P5 parallel-agent dispatch. On every substantive user input, the first-touch agent reflexively selects role lens(es) from `roles/<name>.md`, loads substantive context (files, conventions, domain checklists), and decides single-agent (augment) vs surfaced prompt-refinement (rewrite) vs parallel-team plan (decompose). No "act as X" persona theater — substantive context grounding only. Use when starting any session, before responding to any substantive user input. Composes with P5 (parallel-agent typing), P14 (the lens's quality_bar IS the domain-specific dep-chain trace), P15 (state snapshot feeds signals), and P13 (dream cycle consolidates lens rules from telemetry).

role-x — bstack P17 — Lens-Routed Request Articulation

Primitive: P17 in the Broomva Stack. See broomva/workspace AGENTS.md §P17 for the full reflexive trigger rule and the design spec at docs/superpowers/specs/2026-05-13-role-x-primitive-design.md.

What this skill provides

1. Lens registry: roles/_meta.md (always-loaded base) + roles/<name>.md per-domain lenses. Each lens has YAML frontmatter (signals, context_loaders, quality_bar, prompt_improvement_patterns, default_mode, mode_escalation, out_of_scope) and a prose body.
2. Selection algorithm (reasoning-enforced): score each lens against current signals (paths, prompt_keywords, branch_patterns, linear_labels); threshold ≥ 2 matches; resolve extends: chain.
3. Mode selection (reasoning-enforced): augment (silent context load — default), rewrite (surfaced prompt refinement), decompose (P5 parallel-agent plan, user-approved). Mode escalation per the lens's mode_escalation field.
4. CLI helpers (scripts/role-x.py):
   • role-x list — list all available lenses with status + extends + default_mode
   • role-x validate <path> — validate lens YAML frontmatter against schema
   • role-x index — regenerate roles/_index.md discovery file
   • role-x intake (v0.2.0) — UserPromptSubmit hook entry point
   • role-x suggest (v0.4.0) — analyze events.jsonl; surface fire-rate + drift + emergent clusters
   • role-x init <name> (v0.4.0) — scaffold a status: candidate lens from CLI flags
   • role-x coverage (v0.4.1) — brief registry-health summary; silent when healthy (SessionStart hook entry point)
5. Hooks (scripts/*-hook.sh):
   • role-x-intake-hook.sh (v0.2.0) — UserPromptSubmit wrapper
   • role-x-coverage-hook.sh (v0.4.1) — SessionStart wrapper with 24h cooldown
6. Reference docs (references/):
   • lens-schema.md — YAML frontmatter field reference
   • selection-algorithm.md — scoring algorithm in detail
   • mode-selection.md — augment/rewrite/decompose decision tree
   • feedback-loop.md — Nous-pattern telemetry + P13 consolidation (M2+)

When to invoke

Intake reflex (every prompt)

Always — at the start of every session, before responding to substantive user input. P17 is a reflexive primitive. The skill exists to make the lens registry and CLI helpers discoverable; the behavior is enforced by reasoning + the UserPromptSubmit hook.

Carve-outs (no role-x intake needed): single-line typo fixes, pure read questions ("what does this function do?"), conversation continuation without new substantive request.

Meta-progression discipline (v0.4.1+)

The intake reflex routes prompts in real-time. The meta-progression discipline ensures the registry itself grows from real telemetry:

When	Action	Cadence
SessionStart in a workspace with the role-x coverage hook wired	role-x coverage --since 7d fires automatically; surfaces fire-rate + config hints when registry health drops	≤1 nudge per 24h
Per substantive prompt	If intake routes to _meta only AND prompt is domain-rich (≥8 words, ≥4 distinct meaningful tokens)	Agent sees a 1-line role-x init <slug> suggestion appended to the intake context
When the agent observes a recurring _meta-only pattern within a session (e.g. 3+ unrouted prompts about the same domain)	Propose role-x init <name> to the user as the rule-of-three trigger	At the agent's discretion, surfaced as a one-line note
Weekly (or after collecting ~50+ events)	Run role-x suggest --since 7d for the full report — fire-rate, per-lens drift, emergent keyword clusters (requires sanitized capture on)	Manual, with telemetry signal from the SessionStart nudge
After ≥3 positive-outcome uses of a status: candidate lens	Author promotes the lens to status: active (P16 rule-of-three)	Manual, candidate ledger tracks instances

When NOT to invoke meta-actions

• Single-prompt sessions where the intake nudge is purely informational — don't pause work to author lenses mid-flow
• Edits to existing active lenses unless role-x tune <lens> (v0.5.0+) surfaces concrete drift signals
• New lenses without ≥3 distinct-session evidence in events.jsonl (avoids cargo-cult lens proliferation)

When NOT to invoke

• One-shot read questions answered from context alone
• Conversation-only exchanges (no work to execute)
• Brainstorming / design discussion (use superpowers:brainstorming instead; role-x kicks in once implementation begins)

Composition with other primitives

Primitive	How role-x composes
P5 parallel agents	role-x decompose mode produces the dispatch plan; each sub-agent runs role-x at its scope (typed edges in the reasoning graph)
P13 dream cycle	lens consolidation via role-x-replay.py (M4) — gather → replay → prune → consolidate → index
P14 dep-chain	the lens's quality_bar IS the domain-specific P14 enumeration template
P15 state snapshot	feeds the selection algorithm's signals
P16 bstack engine	new lenses get promoted via per-lens rule-of-three (≥3 positive-outcome uses → status: active)
/autonomous	seeds roles/_meta.md content; remains invocable for the full reflex pipeline
persona-* skills	referenceable from lenses via context_loaders.skills:; not replaced

How to use

1. Start of session — agent reads roles/_meta.md + all roles/*.md (cached in working context). At UserPromptSubmit for substantive work, agent reasons through:
   • Snapshot signals (P15): current branch, touched files (git diff --name-only), prompt content, Linear ticket if any
   • Score each lens against signals (≥2 matches → applies)
   • Resolve extends: chain; merge context_loaders + quality_bar
   • Choose mode (augment / rewrite / decompose) per the lens's default_mode + mode_escalation rules
   • Surface mode + selected lenses to user unless mode is augment
   • Proceed with the user's request, applying the lens's quality_bar as the P14 dep-chain trace
2. Adding a new lens — author roles/<name>.md following the schema in references/lens-schema.md; run role-x validate roles/<name>.md; run role-x index to regenerate roles/_index.md; commit on a worktree branch; PR.
3. Lens consolidation (M4) — python3 scripts/role-x-replay.py <lens-name> runs the P13 dream cycle against ~/.config/broomva/role/events.jsonl.

Cardinal invariant

No act as X persona rewrites. Lenses load substantive context (files, conventions, checklists, optional suggestions). They do not insert persona declarations into the model's working context. The 2026 research (PRISM USC, Zheng et al. arXiv 2311.10054, Anthropic best-practices) is clear: persona declarations don't add expertise and frequently hurt accuracy for code/factual tasks (MMLU drops 71.6% → 66.3% with long expert personas).

Files

• roles/_meta.md — always-loaded base lens (the workspace's implicit "bstack-aware autonomous senior engineer" contract made addressable). Lives in the consuming workspace, not in this skill repo.
• roles/<name>.md — per-domain lenses. Live in the consuming workspace.
• roles/<name>.eval.yaml — resolver-eval fixture (should_fire / should_not_fire intents) asserting the lens's trigger actually routes. Run via role-x.py eval; gate in CI. The skillify "resolver eval" step — a trigger that says "phrase X selects lens Y" is only trustworthy once a test proves it. Live in the consuming workspace alongside the lens.
• roles/_index.md — auto-generated discovery index.
• scripts/role-x.py — CLI helpers (validate, list, index, intake, coverage, suggest, init, eval).
• references/*.md — schema + algorithm reference docs.
• ~/.config/broomva/role/events.jsonl — telemetry log (M2).
• ~/.config/broomva/role/status.json — per-lens stats cache (M2).
• ~/.config/broomva/role/consolidation-runs/ — dream-cycle snapshots (M4).
