Weavenames

Naming for builders.

Weavenames generates project name candidates and verifies their availability across PyPI, npm, GitHub, and domain registries — in parallel — so you stop hand-checking 20 things per name.

uv tool install weavenames
export ANTHROPIC_API_KEY=sk-ant-...
weavenames "open-source memory layer for AI agents, Postgres-native"

Why this exists

Existing naming tools (Namelix, Namesnack, Naming.fyi) generate names but don't check developer registries. You can spend an afternoon hand-verifying PyPI, npm, GitHub, and domains for a single shortlist.

Weavenames does the whole pipeline:

1. Generates ~200 candidates via Claude Haiku 4.5 with taste guardrails.
2. Filters for length, pronounceability, profanity, and similarity to existing infra packages.
3. Checks PyPI, npm, GitHub user/repo, RDAP domains (.com .dev .io .ai), and USPTO trademarks in parallel.
4. Interprets raw availability — flags squatters, premium-priced domains, GitHub-reserved names, pending-delete states (RFC 8056).
5. Ranks with pairwise LLM comparison (ELO over rounds — more stable than 0–10 scoring).
6. Reports a markdown matrix with per-registry status glyphs and rationale.

Phase 1 capabilities

| Stage | Status | Notes | |---|---|---| | LLM generation | done | Claude Haiku 4.5, batches of 50, parallelized | | Heuristic filters | done | length / profanity / pronounceability / collisions / Levenshtein + n-gram similarity | | PyPI / npm | done | Direct registry GET | | GitHub user + repo | done | GITHUB_TOKEN lifts limits to 5K/hr | | RDAP domains | done | whodap via IANA bootstrap, per-TLD asyncio semaphore | | Squatter detection | done | Zero downloads + no GitHub link + 2yr inactive → soft_claimed | | GitHub reserved-name filter | done | Static list of platform-reserved usernames | | RDAP pending delete mapping | done | RFC 8056 statuses → available_soon | | Fastly premium-domain check | done | Skips silently if FASTLY_API_TOKEN not set | | USPTO TESS / TMSearch | done | Top 30, classes 9 (software) and 42 (SaaS) | | Pairwise LLM ranking | done | ELO with stability-based early exit | | Markdown + CSV report | done | Glyph matrix + auto-rationale | | Interactive taste profile | done | ~/.weavenames/profile.json, accept/reject prompt after each run |

Usage

weavenames "your project description here"

# Common flags
weavenames "..." --keywords memory,agent,postgres
weavenames "..." --tlds .com,.dev,.io --top 30
weavenames "..." --target 300 --rank-rounds 6
weavenames "..." --output report.md --csv shortlist.csv
weavenames "..." --no-trademark --no-fastly --no-prompt

Environment

| Variable | Required? | Notes | |---|---|---| | ANTHROPIC_API_KEY | Required | Generation + ranking | | GITHUB_TOKEN | Recommended | Without it, GitHub repo search is skipped and user check is rate-limited at 60/hr | | FASTLY_API_TOKEN | Optional | Enables premium / aftermarket domain detection (10K free / month) | | WEAVENAMES_PROFILE | Optional | Override default profile path (~/.weavenames/profile.json) |

Output legend

| Glyph | Meaning | |---|---| | ✅ | Free | | ❌ | Taken | | ⚠️ | Soft-claimed (squatter / abandoned) | | 🚫 | Reserved (e.g. GitHub platform name) | | 🕒 | Available soon (RDAP pending-delete / redemption) | | 💰 | Premium / aftermarket pricing | | ❓ | Probe error (transient) | | ➖ | Skipped (e.g. .io has no public RDAP server) |

Status

Pre-alpha — Phase 1. Phases 2 (Claude skill wrapper) and 3 (social handles, multi-language profanity, Cloudflare Registrar) are on the roadmap.
