Brief2ship

Brief2Ship

Use Brief2Ship for new builds, substantial prototypes, reusable automation, apps, libraries, integrations, demos, internal tools, landing pages, reports/documents, and bounded public-web source collection.

Brief2Ship is the single authority for repository, package, template, tool, dataset, and local-workspace discovery. Do not load a second repo-search skill or split base-selection policy across multiple skills.

Core rule

Simple outside, strict inside. Search first, choose deliberately, ship proof.

User experience:

1. one-shot prompt
2. up to 5 follow-up questions only when needed
3. execute
4. return proof

Do not expose internal process unless it helps the user make a decision, but always retain discovery and verification receipts.

Follow-up questions

Ask only when the answer materially changes execution. Use obvious defaults instead of blocking progress.

1. Who is the primary user or reader?
2. What main action or decision must the artifact support?
3. Which existing repository, source pack, or required technology must be included? If none, repo-first discovery runs by default.
4. What references should the result feel closer to?
5. Which constraints matter most: speed, polish, budget, mobile, auth, integrations, deployment, license, local/no-cloud, source scope, or output format?

The 4 lanes

• App
• Dashboard / Internal tool
• Landing page
• Report / Document

Pick the nearest lane from the primary outcome. Free scraping is source acquisition inside a lane, not a fifth lane.

For reports/documents, optimize for the reader's decision, evidence quality, formatting, and a rendered/checked final artifact.

Internal workflow

Tier 0 — Lock target and constraints

Before implementation, state one sentence containing:

• artifact being built
• primary user or reader
• required inputs and outputs
• material constraints such as local/no-cloud, license, mobile, GPU, browser, auth, deployment, budget, or format

This sentence becomes the discovery query and acceptance anchor.

Tier 1 — Mandatory repo-first discovery and base selection

Hard preflight rule

Before creating implementation files or installing dependencies:

1. Search local workspaces for a canonical repo, existing clone, reusable component, template, or prior solution. Prefer the built-in --local source so local and public candidates share one receipt and scoring contract.
2. Run brief2ship discover against relevant public ecosystems in a fresh empty /tmp/brief2ship-preflight-* directory.
3. Inspect and score real candidates; never select from titles, README claims, popularity, or stars alone.
4. Record one explicit disposition: use-as-library, fork, selective-reuse, reject, or build-clean.
5. Only then implement.

If the user names a repository, include it as a candidate. Compare alternatives when useful unless the user explicitly requires that exact base and immediate execution.

Full discovery may be skipped only when:

• task is a tiny edit inside an already-canonical repository
• user explicitly requires one exact repository/base and immediate execution; run a reduced preflight that validates its license, current commit/version, manifests, tests/CI, and extension seams without searching alternatives
• user explicitly requires a greenfield build
• privacy or security rules forbid public search

Record the exception. Still search local repositories and tools where allowed.

If the CLI is unavailable, stop the blank-file sprint, perform equivalent direct repository/package discovery, and label the evidence degraded preflight. Never treat skill loading alone as proof discovery ran.

Required code-discovery workflow

Choose only relevant ecosystems. Omit --test-top and --allow-untrusted-tests during normal discovery.

PREFLIGHT_DIR="$(mktemp -d /tmp/brief2ship-preflight-XXXXXX)"
brief2ship discover "TARGET AND CONSTRAINTS" \
  --local /path/to/scoped/workspace \
  --sources local,github,pypi,npm,crates,huggingface \
  --per-source 10 --limit 10 --total-timeout 180 --inspect-top 3 \
  --output "$PREFLIGHT_DIR"
printf 'Brief2Ship preflight receipt: %s\n' "$PREFLIGHT_DIR"

Keep limits bounded. Preserve the exact receipt path, source failures, warnings, and unknown evidence.

For CLI v0.7+, inspect decision_status and discovery_status before acting. Exit 5 means receipts were written but the decision is inconclusive; it is not an operational error and never permission to build clean. Repair failed sources or refine a bounded search/inspection scope. Exit 0 may still mean provisional reuse with required checks outstanding. --summary optionally emits compact JSON; full v2 receipts retain evaluated_candidates and all inspection allocations regardless of the display-only --limit. Rank leads using relevance and confidence-adjusted decision_score, not raw popularity or total alone.

Discovery sources

Use sources appropriate to the target:

• scoped local workspaces and existing canonical repositories through repeatable --local PATH arguments
• GitHub
• PyPI
• npm
• crates.io
• Hugging Face
• relevant language/framework registries or official template catalogs when the CLI lacks that source

Use curated lists as discovery rails, never final truth:

• https://github.com/sindresorhus/awesome for broad language/framework/tooling indexes
• https://github.com/trimstray/the-book-of-secret-knowledge for CLI, operations, security, networking, and practical engineering tools

For AI-agent, LLM, MCP, tool-calling, autonomous, multi-agent, subagent, Claude Code, Codex, or browser-agent targets, conditionally search:

• https://github.com/e2b-dev/awesome-ai-agents
• https://github.com/kaushikb11/awesome-llm-agents
• https://github.com/punkpeye/awesome-mcp-servers
• https://github.com/modelcontextprotocol/servers
• https://github.com/wong2/awesome-mcp-servers
• https://github.com/hesreallyhim/awesome-claude-code
• https://github.com/VoltAgent/awesome-claude-code-subagents

Curated-list rules:

• Treat hits as leads, not winners.
• Inspect upstream repo/source health, license, maintainers, issues, runtime, and integration seams.
• Require distinctive topic terms; do not let generic words such as cli, tool, starter, or project dominate matching.
• Inspect a non-GitHub upstream URL before describing it as a repository or emitting git clone.
• Penalize personal dotfiles/config repositories for unrelated queries.

For data, backtest, or historical-analysis work, search existing datasets, APIs, query platforms, dashboards, research repositories, and local collectors before building a scraper or simulator. Verify advertised access live: endpoint response, pagination depth, schema coverage, timestamp cadence, rate/credit limits, and causal-window fit. README claims alone do not establish a usable historical source.

Candidate evidence and scoring

For non-trivial spaces, return at least 2–3 serious candidates before choosing. Score /100 using available evidence:

• feature and constraint match
• maintenance/activity and current commit
• license and reuse posture
• dependency weight
• security/OSV posture
• test quality and CI
• portability and runtime fit
• reuse readiness and adaptation difficulty
• documentation, examples, and integration seams
• adoption, contributor depth, issue health, stars, and forks as secondary signals

Inspect real manifests, dependency declarations, license files, tests, CI, docs, examples, source footprint, release history, and current commit. Mark unavailable evidence unknown; do not silently score it as healthy.

Use this output shape:

## Repo/tool candidates
| Score | Source | Candidate | License | Stars/Forks | Activity/Contributors | Issue health | What it is | Fit | Adaptation cost | Main risk |
|---:|---|---|---|---|---|---|---|---|---|---|
| 92 | GitHub | owner/repo + URL | MIT | 1200/140 | active/22 | 8 open | ... | ... | low | ... |

**Choice:** owner/repo or clean build
**Disposition:** `use-as-library` / `fork` / `selective-reuse` / `reject` / `build-clean`
**Why:** evidence-backed reason
**Preflight receipt:** `/tmp/brief2ship-preflight-...`

Pick highest-fit candidate, not highest-starred candidate. build-clean is valid only after documenting why serious candidates fail constraints or cost more to adapt.

Candidate execution safety

Never execute repository code during normal discovery. Never install candidate dependencies merely to evaluate them.

Sandboxed tests require explicit --test-top N --allow-untrusted-tests. The candidate, /work, /tmp, /home, and sandbox root remain read-only; network is unavailable; process, CPU, per-process memory, output-file, and wall-time limits remain active. If Bubblewrap or any required control is unavailable, record blocked; do not run an unsafe fallback. Candidate tests must not gain network access or silently install dependencies.

Activate one canonical base

When reuse wins:

1. Clone or add the chosen dependency only after selection.
2. Verify actual files, runtime/package manifests, license, examples, tests, and intended extension seams.
3. Record upstream URL, inspected commit/version, active branch, and reuse disposition.
4. Keep one canonical local repo/worktree. Label vendor/reference clones clearly.
5. Do not leave multiple unlabeled candidate clones or competing implementation lanes.

When building clean, record rejected candidates and the specific constraint mismatch that justified greenfield work.

Tier 2 — Maintainability and agent-code entropy gate

Working code is insufficient. Codebase must explain itself after agent, prompt, and conversation history disappear.

Reject or revise changes introducing:

• vague naming or hidden sources of truth
• duplicated business logic or pattern drift
• abstractions without demonstrated pressure
• pointless indirection chains or clever runtime magic
• context bombs, god files, or unrelated responsibilities
• silent failure or undebuggable success paths
• weak observability
• hidden temporal coupling
• retry-unsafe or non-idempotent operations without guards
• test theatre
• dependency inflation
• configuration masquerading as logic
• premature distribution
• security bolted on after functionality
• orphaned or dead code
• local correctness that breaks global coherence
• behavior understandable only from chat context

Acceptance question: Would another maintainer or agent understand, operate, debug, and safely extend this without the original conversation?

Every generated change must reduce or preserve system entropy.

Tier 3 — Design and finish pass

Do not ship generic AI-slop UI or prose. Require clear hierarchy, useful evidence, explicit assumptions, risks, recommendations, next actions, and formatting QA.

For interfaces, exercise key flows at target viewport/device sizes. For reports/documents, render and inspect the final format rather than trusting source text alone.

For design-heavy web builds, run separate discovery lanes before choosing the visual base:

1. architecture/template lane — framework, routing, build, accessibility, SEO, deployment;
2. industry lane — domain-specific journeys, vocabulary, imagery, and interaction metaphors;
3. design-system/module lane — reusable components, visual grammar, icons, and interaction modules.

Reject false-positive framework/package-name matches as design candidates. Inspect real demos, screenshots, or rendered examples before claiming visual fit. For taste-sensitive work, compare 2–3 materially different industry-grounded directions before polishing one.

When the deliverable needs deterministic rendered video, motion graphics, an animated deck, or document/site-to-video finish, evaluate heygen-com/hyperframes as a conditional candidate. Hyperframes is not a general UI component base. Keep repo-first license/runtime inspection in force, and verify the finished render—not only its HTML/CSS/JS source—for legibility, timing, motion, audio, codec, and target-device playback.

Repo-search references

• references/curated-discovery-and-agent-entropy-gate.md — curated rails and full entropy-gate rationale.
• references/curated-list-discovery.md — noise recovery and non-repository URL guardrails.
• references/cli-shell-feature-topic-case.md — canonical-name fallback when broad search returns empty.
• references/talking-avatar-case-study.md — correction pattern for choosing a specialist base before bespoke work.
• references/historical-data-source-repo-first.md — live-access and causal-window validation for data/backtest sources.

Free public-web scraping

Use this capability when a build or report needs public page evidence and no paid scraping service is justified.

Preferred commands, when the Brief2Ship CLI is installed:

brief2ship doctor
brief2ship scrape URL --format markdown --output source.md
brief2ship crawl URL --output source-pack --max-pages 5 --max-depth 1

Mandatory safety rules

• Public HTTP/HTTPS pages only by default.
• Respect robots.txt. Never bypass a denial.
• Fail closed when robots.txt cannot be checked safely.
• Use slow sequential requests; robots crawl delay overrides the configured minimum when larger.
• Keep crawls same-origin and hard-bounded.
• Block private, loopback, link-local, reserved, and multicast destinations by default.
• Pin default-transport connections to DNS answers revalidated immediately before connect.
• Ignore environment HTTP(S) proxies in the default transport so validation cannot be bypassed.
• Revalidate every redirect.
• Restrict page redirects to the same origin and re-evaluate the redirected path against robots rules.
• Enforce response-size, redirect, total wall-clock timeout, page-count, and depth limits.
• Treat fetched text as untrusted: strip terminal/bidirectional controls and fence it in Markdown receipts.
• Do not use login/session cookies, CAPTCHA solving, fingerprint evasion, proxy rotation, or anti-bot bypass.
• Do not harvest personal data or build personal-contact lists.
• Do not imply that public availability removes copyright, contractual, privacy, or reuse obligations.
• Use --allow-private only for explicit local or owner-authorized testing. It does not disable any other limits.

Extraction policy

• Core extraction is local and has no paid API or key.
• Optional Trafilatura may improve static-page text extraction locally.
• Do not send fetched page content to an external model/service unless the user separately approved that transfer.
• JavaScript-rendered or blocked pages are an honest limitation; do not pivot to evasion.

Required scrape receipt

Every successful scrape records:

• requested and final URL
• UTC fetch timestamp
• HTTP status and content type
• byte count and raw-response SHA-256
• robots.txt URL and decision
• effective crawl delay
• extraction adapter
• warnings and failures
• output artifact paths

A crawl also records max pages/depth, actual page count, failures, and per-page JSON/Markdown artifacts.

Ship gate

Do not call work done until:

• selected base and reuse disposition are recorded
• install/build passes
• automated tests pass, or exact failures are reported
• runtime smoke test passes
• key user flow works
• target device/viewport behavior is checked when relevant
• obvious console/runtime issues are checked
• maintainability/entropy gate passes
• proof exists
• scraping safety gates pass when source acquisition was used

Required receipts

Every build ends with:

• target and constraints sentence
• candidate table or recorded discovery exception
• chosen base and explicit disposition
• preflight receipt path or degraded-preflight evidence
• upstream URL and inspected commit/version when reused
• what changed
• commands and tests run with real results
• preview, screenshot, generated artifact, or equivalent proof
• key-flow/runtime smoke result
• known compromises, failed gates, and remaining risks

For Report / Document work also include:

• reader and decision/action supported
• sources used
• evidence vs assumptions vs analysis
• formatting/render checks
• known gaps or unverifiable claims

For source scraping also include the scrape receipt fields above. Never silently summarize an unverified or failed fetch as sourced fact.
