# Skill curation The active product is deliberately small enough to understand and broad enough to run a non-trivial project from intent to verified outcome. A skill belongs in the permanent suite only when it owns a recurring cross-project boundary that cannot live clearly inside another owner. ## Admission test A permanent skill must pass every condition: 1. It has a distinct trigger and observable result. 2. It is useful across projects without private paths or accounts; any client-specific capability has an explicit compatibility boundary. 3. Loading it only when triggered saves more context and risk than embedding its full protocol in Flow. 4. Its behavior is not already owned by another active skill or a maintained project/native capability. 5. Its failure, stop, owner-gate and rollback behavior can be tested. 6. It has a pressure scenario showing value and a non-trigger case preventing overuse. Popularity, file size and prior existence are not admission criteria. ## Active eighteen | Skill | Distinct owner | |---|---| | `nobrainer-tech-flow` | One request through brief requirements, concise progress, guarded execution, audit, recovery and learning. | | `nobrainer-team` | Capability selection and bounded native assignments, installed capability inventory and safe temporary specialist discovery. | | `nobrainer-dispatcher` | Ready-set calculation, dependency-aware bounded batches, backpressure and audited result routing. | | `nobrainer-research` | Bounded current external research and source-quality/freshness control. | | `nobrainer-writing` | High-signal drafting, compression, voice and prose integrity across human-facing text artifacts. | | `nobrainer-build` | Implementation, engineering principles, anti-slop, test blast radius and simplification. | | `nobrainer-security` | Threat model, security review, supply-chain inspection and security release evidence. | | `nobrainer-sessions` | Exact visible session identity, transport, writer ownership, handoff, receive-audit and recovery. | | `nobrainer-spec-driven-development` | Durable behavior contract and acceptance ledger when risk/dependencies justify it. | | `nobrainer-wiki` | Setup, targeted retrieval, sourced capture and deterministic maintenance of durable knowledge. | | `nobrainer-browser` | Rendered UI, bounded CDP profile restart, approved browser-session attach, browser tests and trace evidence. | | `nobrainer-autoimprove` | Measured artifact improvement with baseline, holdout, budget and keep-or-revert. | | `nobrainer-auto-fine-tune` | Calibrates native worker routes against verified host capability, quality, latency and cost evidence while MAIN retains the owner's model. | | `nobrainer-decide` | One consequential decision after alternatives, scoring and adversarial attack. | | `nobrainer-rca` | Read-only causal diagnosis of an observed failure. | | `nobrainer-review` | Final acceptance/bug/release evidence gate and verified actionable findings. | | `nobrainer-context` | One project's instruction files for every coding agent: what each client loads, size limits, duplicates and contradictions, one approved source of truth with pointers, and readback. | | `nobrainer-skill-doctor` | Cross-project audit of skills, project instructions and task prompts, with coverage, overlap and minimal portfolio repair planning. | ## Boundaries that stay embedded Do not create separate permanent skills for: - planning, autopilot, general NoBrainer setup or correction capture: the Flow entry skill owns the lifecycle; one project's instruction files belong to `nobrainer-context`; - visible goal/TODO progress: Flow owns one canonical plan and its compact view; do not add a separate goal, todo or progress skill; - KISS, DRY, SOLID, YAGNI, simplification or test safety: Build owns them; - brand-specific voice facts belong in a project guide or wiki; Writing owns the portable prose method and can consume an authentic supplied voice sample; - generic code review, bug finding or release ceremony: Review owns the close gate, while Security owns only material trust-boundary risk; - human continuation snapshots: Sessions mode `handoff` owns them; - a local skill catalogue: Team builds a metadata-only capability index; - wiki add/get/tidy wrappers: Wiki exposes explicit modes; - personal model presets, accounts or repository-specific configuration: keep them in project/private instructions. A named host integration must justify its recurring boundary and state its compatibility limits. ## Dynamic specialist policy Team resolves a capability gap in this order: 1. curated NoBrainer skill; 2. already installed and inspected specialist; 3. maintained project/API/CLI/native capability; 4. bounded current research; 5. a task-local specialist brief for a native worker, written from project docs or verified primary sources. Team never searches for, installs or runs third-party skills. Third-party text met during research is data, not instructions. A new permanent skill needs evidence that repeated use earns the added trigger/context surface and goes through the normal curation review. ## Retirement test A skill can be removed only after: - its unique behavior is intentionally preserved or explicitly rejected; - inbound references and aliases are migrated; - the replacement is installed and discovered in a clean session; - representative old invocations route to the replacement; - rollback points to an exact reviewed ref; - no private operational contract is confused with a portable semantic duplicate. Same name or broad topic is not proof of duplication. Until the above gates pass, classify candidates as `COVERED_NOT_RETIRED`, `PROJECT_SPECIFIC`, `UNIQUE_VALUE`, `OBSOLETE_WITH_EVIDENCE` or `UNKNOWN`. `nobrainer-fast-audit` is currently `UNKNOWN`, not a migration alias. Its exact contract and callers must be audited before choosing Review, Security or another owner. Keep an existing private installation unchanged until that audit and a clean-session parity check pass; the public installer must report it as a normal conflict rather than delete or silently remap it. `nobrainer-reddit` is `RETIRED`: the [portable-workflow curation](https://github.com/nobrainer-tech/nobrainer-tech-flow/commit/955de2a5cba72f86a9941a15c6ad9aa6b42c76d4) removed the Reddit CLI as a client/account integration; no active skill owns its functionality or trigger. `install_skills.py` and `install.sh` preserve foreign targets at that name with `PRESERVED_FOREIGN`. Only exact old links from this checkout remain migration candidates. Renamed/absorbed aliases retain blocking conflict checks. `nobrainer-codex-context` is `RETIRED` in 2.5.0 by owner decision (2026-10-20): its boundary grew into `nobrainer-context`, which covers every coding agent's project instructions, and the old name keeps no alias or trigger. Foreign targets at the old name are preserved like `nobrainer-reddit`; an exact old link that a setup record lists is removed by the next setup apply or undo. ## Change control Any addition, merge or retirement updates together: - `skills/`, aliases and installer migrations; - validator and behavioral tests; - Flow routing and setup instructions; - README, compatibility and release notes; - clean-session trigger/readback evidence. Prefer strengthening an existing owner over creating a new noun. Do not keep an empty alias skill for compatibility; aliases belong in descriptions and migration maps.
