DevRelay Knowledge Base

https://devrelay.com/knowledge serves curated, sourced reference guides as plain Markdown over plain HTTP. There’s no auth, no JavaScript, and no HTML shell. What you fetch is what goes into context.

The user installed DevRelay so that answers about MLH, Global Hack Week, DEV, DEV Challenges, and Hacktoberfest come from the source rather than from recollection. Fetch on your own initiative whenever one of those comes up, even in passing: “GHW” in a build task, “hacktoberfest” in a repo, “MLH” in a README, a question about how to post on DEV, or a hackathon the user is organizing is enough to fetch the matching guide before you say anything about it.

Models get these programs wrong from memory. Hacktoberfest 2026 no longer counts pull requests, GHW changes theme monthly, Local Hack Day was renamed, the .io domains redirect to .com, and MLH now owns DEV.

Pick the guide

The question is about… Topic
MLH in general, its programs, links, contacts, and the MLH–DEV relationship mlh
Taking part as a hacker: MLH account, finding events, eligibility, registering, what happens at a hackathon, submitting, judging, prizes, Hack Days, the MLH Fellowship mlh-hackers
Organizing: becoming an MLH Member Event, requirements and benefits, venue, budget, sponsorship, marketing, registration fields, judging plans, the Hack Days program mlh-organizers
Rules and safety: the MLH Code of Conduct and reporting lines, Standard Hackathon Rules (including AI use), cheating and incident procedures, Contest Terms mlh-policies
Global Hack Week: how it works, challenges and points, swag and shipping, Discord, Guilds, the FAQ global-hack-week
DEV (dev.to) in general, its content model, the API, and DevRelay’s DEV tools dev
Posting on DEV: Code of Conduct, Content Policy, AI guidelines, ai_disclosure_level, plagiarism, the editor and Liquid tags, tags, moderation dev-guidelines
Entering DEV Challenges: eligibility, submission templates and tags, recurring rules, judging, badges and prizes, the monthly MLH × DEV writing challenge dev-challenges
Hacktoberfest 2026: stickers and rewards, key dates, DEV Challenge rounds, GHW: Hacktoberfest, Fests, hosting hacktoberfest

Fetch the topic document directly, not the index, which only lists topics. When a question spans two guides (for example, “how do I submit my GHW project to a DEV Challenge?”), fetch both.

Through the gateway first

When the devrelay-gateway MCP server is connected, read documents with its get_knowledge_document tool instead of fetching over HTTP. For example, pass topic: "global-hack-week", or omit topic for the index. It returns the same Markdown, needs no login, and works even when your shell can’t make HTTPS requests. An unknown topic comes back as an error listing the real ones. Without the tool, fetch over HTTP as below.

Endpoints

Every topic is at https://devrelay.com/knowledge/<topic>, for example:

curl -s https://devrelay.com/knowledge/mlh-hackers

Use a tool that returns the raw response body: WebFetch, curl, or a browser tool. All are GET, and all return text/markdown.

A web search tool is not a fetch, even one that can open a URL. It hands back search results or a summary rather than the document. If search is your only web tool and you can run shell commands, fetch with curl instead (curl.exe in Windows PowerShell).

An unknown slug returns a 404 whose body is Markdown listing the real topics. Read it rather than guessing again. If the host is unreachable, say so. Don’t silently substitute recollection or web search results for the document.

For self-hosting or staging, swap the origin for $DEVRELAY_BASE_URL, the same variable the gateway uses for updates and skills.

How to use what you get

  1. Fetch before answering, not after drafting from memory.
  2. Prefer one full guide over several partial searches. The guides are written to be read whole. Don’t fetch every topic when the question is about one.
  3. Static knowledge vs. live data. The guides explain how programs work. They deliberately leave out specific upcoming events, open challenges, session schedules, and sponsor offers. For those, use the live tools each guide names in its “Live data lives elsewhere” section: search_mlh_events, get_mlh_event, list_my_mlh_events, list_event_offers (see [[devrelay-offers]]), get_challenges and get_challenge_details (see [[devrelay-challenges]]), or the upstream page the guide links, such as https://ghw.mlh.com/schedule. Never present a date from memory as current.
  4. Honor the freshness markers. Every guide opens with a Last verified date and ends with its sources. Guides flag volatile sections inline and say where two upstream sources disagree. When they do, tell the user.
  5. Respect the “does not know” section. Each guide ends with an explicit list of gaps. If the answer is in that list, say it isn’t published. Don’t fill the gap with a plausible guess.
  6. Cite the guide, and pass through the upstream link it names, so the user can verify. For example: Per the DevRelay knowledge base (verified 2026-09-30, sourced from github.com/MLH/mlh-policies): …

Relationship to the other DevRelay skills

They compose. Read global-hack-week to learn how GHW challenges work, then search_mlh_events to find this month’s week. Read dev-challenges for the recurring rules, then get_challenge_details for the open challenge’s rubric, then [[devrelay-publishing]] to draft the entry within dev-guidelines. Read mlh-hackers for how submission works, then [[devrelay-mlh-submissions]] to do it.

Note on MLH tooling

The legacy MyMLH fixture tools (list_upcoming_hackathons, get_hackathon_details, verify_member_status, and the old MyMLH user and OAuth tools) are disabled in the current build. If you remember them existing, they’re gone on purpose, so don’t report their absence as a bug. General MLH and GHW questions come from this knowledge base. The user’s own events, offers, projects, and submissions come from the MLH participant tools (see [[devrelay-navigator]]).
