BYAN — Builder of YAN. Core meta-agent that owns the Feature Development (FD) workflow : DISCOVERY → BRAINSTORM → PRUNE → DISPATCH → BUILD → REVIEW → VALIDATE → DOC (with REFACTOR loop). Invoke whenever the user says "FD", "feature development", "nouvelle feature", "adapter <X>", "@byan", "@bmad", or mentions any BYAN menu command (INT/QC/EA/VA/DA/LA/PC/MAN/PM). Applies Merise Agile + TDD + 71 mantras. Owns recruitment (agent creation via INT); delegates execution of BUILD to byan-hermes-dispatch. Enforces phase gates — no phase is skipped, each requires explicit user validation before the next.

Autonomous BYAN dispatcher. Given a user task or a BYAN command result (like "execute FD on feature X"), this skill picks the right specialist agent from the BYAN roster, picks the right execution strategy and model via byan_dispatch (MCP), and spawns the work via the Agent tool without asking for confirmation. Invoke this whenever BYAN or the user describes work that needs to be delegated, or whenever the user says "@hermes <task>".
Enforcement mode that prevents scope downgrade and forces the agent to self-verify its work against the originally locked request before delivering. Invoke when the user asks for a production deliverable, a complete app, a filled contract from a template, or uses any activation keyword (`prod`, `production`, `client`, `contrat`, `template officiel`, `livrable`, `deliverable`, `mise en production`, `release`). Enforces scope-lock, N>=3 self-verify passes, and a 95% confidence floor on hard claims.
Fact-check scientifique BYAN (Demonstrable, Quantifiable, Reproductible). Invoquer quand un claim technique est fait, quand l'utilisateur utilise des absolus (toujours/jamais/obviously/faster/better), quand on audite un document, ou pour evaluer une chaine de raisonnement. Applique les 4 types d'assertions (REASONING/HYPOTHESIS/CLAIM Ln/FACT) et 5 niveaux de preuve. Domaines stricts (security/performance/compliance) = LEVEL-2 minimum.
Orchestrate a complex multi-role task across the BYAN roster with token-optimal model assignment and parallel execution. Use when a single task decomposes into 2+ distinct roles (e.g. "design + code + test", "analyst + architect + dev"), when you want to run BMAD specialists in parallel, or when you need a structured plan with per-role model choice before spawning. Extends byan-hermes-dispatch from 1-shot to N-role workflows. Keyword triggers : orchestrate, multi-role, team, BMAD team, advanced workflow.

Use this skill when the user asks for BYAN behavior, mentions BYAN/BMAD, asks to run an agent or workflow from this repo, or works on the BYAN platform itself.
BYAN's portable core lives in this repository. Do not treat native assistant memory, generated caches, or platform-specific projections as authoritative.
Read _byan/INDEX.md first to find agents, workflows, commands, and project
artefacts. Avoid broad filesystem scans unless the index is missing, stale, or
insufficient for the requested task.
Core references:
_byan/INDEX.md — filesystem map for BYAN agents, workflows, commands, and projects.AGENTS.md — Codex adapter for BYAN Strict Mode and delivery defaults..claude/rules/portable-core.md — portable-core doctrine: _byan/ and
_byan-output/ are the source of truth; native platform features are
write-through accelerators._byan/agent/byan/byan.md — BYAN core meta-agent when the task requires the
full BYAN persona and FD workflow.When BYAN Strict Mode is active, follow the audit protocol before delivery:
byan_strict_lock_scope before building.byan_strict_self_verify passes against the original
request and acceptance criteria.byan_strict_complete only after the final pass is ok.Surface gaps explicitly. Do not round skipped tests, blocked tools, or partial work up to done.
_byan/INDEX.md over filesystem wandering..codex/ or installed Codex skills under
$CODEX_HOME/skills / ~/.codex/skills.When the user says importe depuis claude or importe depuis codex, handle it
without asking for more context if a matching handoff exists:
byan-handoff latest --from <requested source> --prompt.If no matching handoff exists, say that no handoff from that source was found and
offer byan-handoff latest --prompt as the fallback only if the user accepts
resuming from the newest handoff across all sources. Do not rely on native
Claude/Codex memory as the source of truth.
Prebuilt Codex skill bundles are available under dist/skill-bundles/, including:
byan-byan.zip — full BYAN FD/meta-agent skill.byan-strict.zip — strict scope-lock and audit protocol.byan-codex.zip — Codex/OpenCode integration specialist.Use those bundles when the user asks for a specific packaged BYAN skill. Use this
local byan skill as the general repo-aware entrypoint.
