This week in the forge

Highest SkillScore records across all 10,000+ indexed skills. Every card opens a full breakdown: factors, seal, SKILL.md and one-command install.

PR Reviewer

Senior-dev code review in 60 seconds

Reviews diffs like a strict senior: correctness, edge cases, perf traps, and security smells — with file:line references and suggested patches.

Test Forger

Tests that actually catch regressions

Generates boundary-focused tests from implementation code: happy path, edges, failure modes — plus the one test the author hoped nobody would write.

Regex Wizard

Readable regex with test cases attached

Writes correct regexes with plain-English breakdowns and positive/negative test cases — plus a non-regex alternative when that is saner.

CSV Surgeon

Messy spreadsheets, clean datasets

Diagnoses CSV chaos — encodings, delimiters, dirty nulls — then produces a cleaning plan and validation report your pipeline can trust.

Deep Researcher

Multi-source research briefs with cited claims

Turns a question into a structured brief: gathers sources, extracts claims with citations, flags contradictions, and writes a cited summary your agent can quote safely.

03ENGINE

Advanced under the hood, calm on the surface

Live signals, sealed fallback

GitHub, npm, MCP servers and Hacker News refresh the catalog. If any feed fails, the 10,000-record sealed offline catalog keeps every page, demo and first paint alive.

One engine, three consumers

SkillScore is deterministic and keyless: docs, breadth, compatibility, license, community, safety. The same function powers the UI, the REST API and the MCP tools.

Your agent can shop here

Five MCP tools — search, get, score, compose, verify — over JSON-RPC. Paste the mcp.json block and any capable agent can install skills by itself.

Integrity you can replay

Every record carries a SHA-384 hash chained to its predecessor. POST the ids to /api/seals/verify and watch 10,000 hashes recompute in under a second.

06 — SAFETY

Skills are code that acts. Score the risk before you grant it.

From prompt tricks to recursive self-improvement, the road to superintelligence runs through agents executing skills. SkillForge maps every skill to a machine-readable risk surface, a 0–100 safety score, and guardrails your agent must obey.

Read the alignment briefing

07CONTRIBUTE

Forge the 10,001st skill

The catalog grows the way good infrastructure should: one reviewed, risk-declared, sealed record at a time.

01

Fork and add your skill

One record in src/lib/fallback.ts: id, triggers, workflow, guardrails, honest risk flags.

02

Declare risk honestly

exec-code, writes-files, network-egress, external-api, reads-secrets — the engine scores what you declare.

03

Pass lint and build

npm run lint plus npm run build, both green. No keys, no paywalled deps, ever.

04

Open the PR

Maintainers check scoring honesty and guardrail quality. Merged skills ship sealed to 10,000+ neighbors.

08QUESTIONS

Asked by humans and agents alike

+Does it cost anything? Do I need API keys?

No and no. The catalog, scoring, MCP tools, and installs are free forever with zero keys. Live feeds use keyless public APIs; everything degrades to the sealed offline catalog when a feed fails.

+Where do 10,000+ skills come from?

A harvester indexes real public sources — GitHub agent/skill/MCP repos, npm agent packages, official MCP servers, and exact SKILL.md bodies — then seals every record into a SHA-384 chain. Re-harvests refresh the catalog; the harvest script ships in scripts/harvest.mjs.

+How does SkillScore work?

Six deterministic factors: documentation completeness, capability breadth, multi-agent compatibility, license openness, community signal, and safety posture — plus a separate 0–100 safety score from declared risk flags. Same function serves the UI, REST, and MCP.

+How does my agent use it?

Add public/mcp.json to your agent config and it gets five tools: search_skills, get_skill, score_skill, compose_bundle, verify_seal. Humans get the same power over REST plus one-command curl installs.

+Can I trust a high score?

Scores are heuristics, not guarantees. Always read the SKILL.md, check the safety number, verify the seal, install least-privilege first, and never paste secrets into a skill. The safety briefing explains the full model.

+How do I publish my skill?

Fork the repo, add one record to src/lib/fallback.ts with honest risk flags, keep lint and build green, open a PR. The authoring guide in Docs walks through it in five moves.
