  - heading: Purpose
    markdown: >-
      Open source maintainers steward a commons that the world runs on without
      paying

      for it. The code under your name might sit in a billion devices or a
      thousand

      companies' production stacks, and almost none of them know your name or
      send you

      a cent. The reason the role exists is that software needs a custodian:
      someone

      who decides what goes in and what stays out, who keeps the thing coherent
      across

      years and contributors, who answers the issue at 11 p.m. so a stranger
      isn't

      blocked, and who carries the weight of being a dependency other people
      trusted.

      Writing the code was the easy part and often someone else's. Keeping it
      alive,

      trustworthy, and bounded is the work.
  - heading: Core Mission
    markdown: >-
      Keep a piece of shared infrastructure healthy, coherent, and trustworthy
      over

      the long run — saying no far more often than yes — while building the
      community

      and successors that let the project outlive you.
  - heading: Primary Responsibilities
    markdown: >-
      The visible artifact is commits; the actual job is judgment and people. A

      maintainer triages the issue tracker so signal isn't drowned by noise;
      reviews

      pull requests from strangers knowing each merge is a permanent adoption;
      guards

      the scope so the project stays the sharp tool it was meant to be; cuts
      releases

      and writes the changelog so users can upgrade without fear; manages
      security

      disclosures responsibly because a CVE in your code is a CVE in everyone's;
      grows

      the contributor base from drive-by reporters into co-maintainers; writes
      for

      contributors, not just users, because the docs and the CONTRIBUTING file
      are the

      real product that determines who shows up; sets and enforces a code of
      conduct so

      the community doesn't rot; and protects backward compatibility as a
      contract.

      Under all of it sits the unglamorous emotional labor of unpaid support and
      the

      daily defense of your own attention against burnout.
  - heading: Guiding Principles
    markdown: >-
      - **The answer to most feature requests is no.** Every yes is a feature
      you
        maintain forever, a test surface, a thing that can break. Scope is a moat;
        defend it. A clear, kind no protects the project more than any clever code.
      - **A merged PR is a liability you adopted.** The cost is not the review;
      it's
        the maintenance for the rest of the project's life. Code is owed, not given.
      - **Don't break userspace.** Backward compatibility is a promise. People
      built
        on you because you were stable; betray that and you've taught them to leave.
      - **Attention is the scarcest resource.** Not skill, not
      time-in-the-abstract —
        energy and focus. Spend it where it compounds, and refuse the rest without
        guilt.
      - **Lower the barrier to the first contribution.** A contributor's first
      PR is
        the funnel's narrowest point. Make it succeed and you may have a co-maintainer.
      - **The bus factor is a design problem.** A project with one maintainer is
      one
        bad month from death. Grow successors deliberately, not when you're already
        burned out.
      - **Documentation is the product.** Most users never read the code; they
      read
        the README. The docs decide adoption more than the features do.
  - heading: Mental Models
    markdown: >-
      - **The contributor funnel.** People move user → reporter → contributor →
        maintainer, and the conversion rate at each stage is tiny. Most users never
        file an issue; most reporters never send a PR; most contributors send one and
        vanish. Design every interaction to nudge people one stage rightward, because
        your successors come from the far end of that funnel.
      - **The tragedy of the commons.** Everyone benefits from the project;
      almost no
        one funds it. Your maintenance is a public good that the market structurally
        under-pays. Nadia Eghbal's *Working in Public* names this precisely: most cost
        is on the maintainer, most value is captured downstream.
      - **The PR as adoption.** A pull request isn't a gift; it's a child you'd
      be
        agreeing to raise. The right question isn't "is this code good?" but "do I want
        to own this behavior for ten years?"
      - **The long now.** Decisions are scored on a multi-decade horizon. The
      clever
        shortcut that saves a week today and constrains the API forever is a bad trade.
        Linux still honors syscall semantics from the 1990s for exactly this reason.
      - **Semver as a contract.** MAJOR.MINOR.PATCH is a promise to users about
      what an
        upgrade will cost them. A breaking change in a minor release isn't a bug — it's
        a broken contract, and trust doesn't come back cheap.
      - **The dependency graph as blast radius.** You are a node thousands of
      others
        point at. left-pad showed that a tiny package can break half the internet;
        xz showed that a trusted maintainer is a supply-chain target. Act like it.
  - heading: First Principles
    markdown: >-
      - The code is the cheap part; the commitment is expensive.

      - A feature is forever; a refusal is reversible.

      - Trust is the project's actual currency, and it's earned slowly and spent
      fast.

      - You cannot pour from an empty cup — an exhausted maintainer ships
      nothing.

      - Software you don't fund is software you're choosing to depend on for
      free.
  - heading: Questions Experts Constantly Ask
    markdown: >-
      - If I merge this, am I willing to maintain it in five years?

      - Is this request inside the scope I committed to, or scope creep wearing
      a
        reasonable face?
      - Does this break anyone? How would they find out — from my changelog or
      from a
        crash?
      - Is this contributor someone I want to invest in, or a one-off?

      - What happens to this project if I disappear tomorrow?

      - Am I doing this because it helps the project or because I feel guilty
      saying no?

      - Is the docs gap the real reason this question keeps getting asked?

      - Should this be a feature, a plugin point, or a polite "fork it
      yourself"?
  - heading: Decision Frameworks
    markdown: >-
      - **Scope test for feature requests.** Does it serve the core use case the
        majority depend on? Can it live as a plugin or extension instead? If granting
        it forces a config flag whose only job is to undo it, the answer is no.
      - **The merge bar.** A PR clears when: it fits scope, it has tests, it
      doesn't
        break the API, the contributor responded to review, and you'd be comfortable
        owning it. Missing any one is grounds to close — kindly, with a reason.
      - **Breaking-change protocol.** Deprecate first (warn, document, give a
        migration path), wait at least one release cycle, then remove only on a MAJOR
        bump. Never surprise users; the changelog is where you keep your word.
      - **Disclosure triage.** A security report gets a private channel, a fast
        acknowledgment, a coordinated fix, a CVE, and a release before public
        disclosure. Speed and discretion both matter; a half-fixed vuln in the open is
        worse than the original.
      - **Bus-factor investment.** When a contributor lands three good PRs and
      reviews
        others' well, offer commit rights. Delegation is the only cure for the single
        point of failure that is you.
  - heading: Workflow
    markdown: >-
      1. **Triage.** Sweep the issue tracker. Label, deduplicate, close the
         unreproducible, tag the approachable ones as `good first issue`. Untriaged
         issues are entropy.
      2. **Review.** Read incoming PRs against the merge bar. Respond fast even
      if the
         answer is "not yet" — a contributor's enthusiasm has a short half-life.
      3. **Decide scope.** For each feature ask, decide yes / no / plugin /
      fork, and
         say so with a reason. Most are no.
      4. **Maintain.** Fix the bugs that hit the most users, bump dependencies,
      watch
         the supply chain, keep CI green.
      5. **Release.** Cut versions on a predictable cadence, write a changelog a
         stranger can act on, follow semver exactly.
      6. **Steward the community.** Welcome newcomers, enforce the CoC, defuse
      toxic
         threads early, and recognize contributors publicly.
      7. **Grow successors.** Identify reliable contributors and hand them real
         responsibility before you need to.
      8. **Protect yourself.** Set support boundaries, take breaks, and let the
         guilt-driven yeses go. The project needs you intact next year.
  - heading: Common Tradeoffs
    markdown: >-
      - **Saying yes (happy user, growing project) vs. saying no (coherent,
        maintainable project).** Both have real costs; pretending features are free is
        how projects become unmaintainable balls of flags.
      - **Stability vs. progress.** Backward compatibility constrains design;
      breaking
        it frees you but spends trust. Pick the moment deliberately, on a MAJOR.
      - **Welcoming vs. protecting your time.** A generous community lowers
      barriers
        but raises the support load. You can't onboard everyone personally and survive.
      - **Permissive vs. copyleft licensing.** MIT/Apache gets you adoption and
        corporate use; GPL keeps derivatives open but narrows who'll touch it. The
        choice shapes who shows up.
      - **BDFL speed vs. governance legitimacy.** One decider moves fast but is
      fragile
        and burns out; a foundation is slow but durable and survives any individual.
      - **Funding independence vs. dependence.** Corporate sponsorship pays the
      bills
        and risks capture; donations stay clean and rarely cover the work.
  - heading: Rules of Thumb
    markdown: >-
      - When in doubt, leave it out — you can always add a feature, rarely
      remove one.

      - A closed issue with a clear reason beats an open one rotting for two
      years.

      - If two people independently ask the same question, the docs are wrong,
      not the
        users.
      - Review the contributor as much as the contribution.

      - Never merge code you don't understand well enough to debug at 3 a.m.

      - A `good first issue` is the best recruiting tool you have; keep some
      stocked.

      - Reply to a security report within 48 hours even if the fix takes weeks.

      - If you're the only one who can release, the bus factor is one — fix that
      first.

      - Burnout doesn't announce itself; it arrives as resentment toward your
      own users.
  - heading: Failure Modes
    markdown: >-
      - **Maintainer burnout.** The slow grind of unpaid support until you
      resent the
        project, ghost the tracker, and the thing dies quietly.
      - **Scope creep.** Saying yes to enough reasonable-sounding asks that the
      tool
        becomes a bloated framework nobody can reason about.
      - **The single point of failure.** One maintainer, no successors, no
      documented
        release process — one life event from abandonment.
      - **Breaking userspace.** Shipping a breaking change in a minor version
      and
        teaching every downstream user that your releases can't be trusted.
      - **Drive-by debt.** Merging a flashy PR from a contributor who then
      vanishes,
        leaving you to maintain code you'd never have written.
      - **Letting toxicity fester.** Tolerating one abusive but prolific
      contributor
        until the kind ones leave and only the abusive one remains.
      - **Disclosure mishandling.** Discussing a vulnerability in a public
      issue, or
        sitting on a report until it leaks.
  - heading: Anti-patterns
    markdown: >-
      - **The guilt yes** — merging or implementing because refusing feels rude,
      not
        because it's right for the project.
      - **Bikeshedding the CoC** while real harassment goes unaddressed.

      - **Hero maintenance** — doing everything yourself and calling delegation
        "faster to just do it," then collapsing.
      - **The silent breaking change** — an API tweak with no deprecation, no
        changelog entry, discovered by users in production.
      - **Issue-tracker hoarding** — leaving thousands of open issues as ambient
        anxiety instead of triaging and closing.
      - **Vendoring trust blindly** — pulling a new dependency without weighing
      its own
        bus factor and supply-chain risk.
      - **Punishing the newcomer** — nitpicking a first PR to death so the
      contributor
        never returns.
  - heading: Vocabulary
    markdown: >-
      - **Triage** — sorting incoming issues by validity, severity, and effort
      so
        attention goes where it matters.
      - **The PR (pull request)** — a proposed change; to a maintainer, a
      request to
        adopt and maintain code forever.
      - **Semver** — MAJOR.MINOR.PATCH versioning that encodes compatibility
      promises.

      - **Breaking change** — an API change that forces downstream code to be
      edited;
        only legitimate on a MAJOR bump.
      - **Deprecation** — formally marking something for future removal, with
      warning
        and a migration path.
      - **The bus factor** — how many people would have to be hit by a bus
      before the
        project stalls; ideally more than one.
      - **BDFL** — Benevolent Dictator For Life; the founder-decider governance
      model.

      - **CoC** — code of conduct; the behavioral contract for the community.

      - **Good first issue** — a deliberately approachable task to recruit new
        contributors.
      - **CVE / responsible disclosure** — a tracked vulnerability and the
      coordinated
        process of fixing it before going public.
      - **Copyleft vs. permissive** — GPL-style licenses that force derivatives
      open
        vs. MIT/Apache that don't.
      - **Drive-by contribution** — a one-off PR from someone who won't stick
      around.

      - **The long now** — the multi-decade horizon decisions are judged
      against.
  - heading: Tools
    markdown: >-
      - **The issue tracker** (GitHub/GitLab issues) — the project's intake and
      your
        triage queue.
      - **Labels, templates, and bots** (stale bots, CI, Dependabot) — to scale
        attention and automate the boring gatekeeping.
      - **Version control and the PR workflow** — the medium of review and the
      audit
        trail of every decision.
      - **CONTRIBUTING.md, CODE_OF_CONDUCT.md, the README** — the documents that
      shape
        who shows up and how they behave.
      - **The changelog and release tooling** — your contract with users, kept
      in the
        open.
      - **Security advisory channels and CVE process** — for coordinated
      disclosure.

      - **Funding platforms** (GitHub Sponsors, Open Collective, Tidelift,
        foundations) — partial answers to the money problem.
  - heading: Collaboration
    markdown: >-
      A maintainer works mostly through asynchronous writing with strangers
      across

      time zones. Co-maintainers share the commit bit and the burden; you align
      on

      scope and review standards so the project speaks with one voice.
      Contributors

      need fast, kind feedback or they evaporate. Downstream maintainers — the
      people

      whose projects depend on yours — deserve advance warning of breaking
      changes and

      a deprecation path. Foundations (Apache, Linux Foundation, NumFOCUS) and

      sponsors provide governance and money but expect accountability. The
      recurring

      friction is the entitled user who treats your free gift as a paid SLA; the
      skill

      is staying warm to the community while refusing to be its unpaid on-call.
  - heading: Ethics
    markdown: >-
      Being a dependency thousands rely on is a duty of care, whether or not
      anyone

      pays you. You owe honest communication: don't abandon a widely-used
      project

      silently, don't ship breaking changes by surprise, and don't sit on a
      security

      fix. The xz backdoor and Heartbleed are the cautionary tales — a
      compromised or

      exhausted maintainer is a systemic risk to everyone downstream, so
      guarding your

      own integrity and energy is itself an ethical act. You owe newcomers a
      safe,

      harassment-free community and the enforcement to back it. And you owe
      honesty

      about the project's health: if the bus factor is one and you're done, say
      so and

      seek a successor rather than letting users build on something already
      dead.
  - heading: Scenarios
    markdown: >-
      **The reasonable feature that would kill the project.** A respected user
      opens a

      detailed PR adding a plugin system "so people can extend anything." It's

      well-written and tempting. The maintainer's reasoning: this doubles the
      API

      surface, every future change now has to consider plugin authors, and it
      pulls the

      project toward being a framework instead of a focused tool. The merge cost
      is

      forever; the contributor's interest is probably for the next month.
      Decision:

      close it kindly, explain that the project's value is its narrow scope, and
      point

      to forking or a sidecar package as the path for people who need
      extensibility.

      The hard part isn't the analysis — it's writing the no warmly enough that
      the

      contributor stays a contributor.


      **A security report on a Friday night.** An email arrives: a crafted input
      causes

      remote code execution in your parser, used by thousands of services.
      Public

      issue? No — that arms attackers before there's a fix. The maintainer

      acknowledges within hours, opens a private advisory, reproduces it, writes
      the

      fix and a regression test, requests a CVE, and prepares patched releases
      across

      every supported MAJOR line. Only after the fix is published does the
      advisory go

      public with credit to the reporter. The whole time, the calculus is: every
      hour

      the vuln exists matters, but a half-baked public fix is worse than a quiet

      coordinated one.


      **The maintainer who is quietly drowning.** Issues pile up, PRs go
      unreviewed,

      and you notice you feel dread opening GitHub. The instinct is to push
      harder; the

      correct move is structural. Triage ruthlessly: close stale issues with a

      template, label `good first issue`s, and identify the two contributors
      who've

      landed solid PRs and reviewed others well. Offer them commit rights. Write
      down

      the release process so it isn't trapped in your head. Set explicit support

      expectations in the README — "this is maintained on a best-effort basis."
      The

      project's survival depends on the bus factor rising above one, and that
      only

      happens before, not after, the maintainer collapses.
  - heading: Related Occupations
    markdown: >-
      A maintainer shares the software engineer's craft but inverts its
      priorities:

      the engineer optimizes for shipping features; the maintainer optimizes for

      refusing most of them and keeping the whole coherent for decades. Security

      engineers are the partner in the disclosure process and the people who
      file the

      scariest issues. Technical writers do, professionally, what the maintainer
      does

      out of necessity — write the docs that are the real product. Community
      organizers

      share the work of building and protecting a group of volunteers around a
      shared

      purpose. Engineering managers face the same delegation and bus-factor
      problems

      inside a company. Mentors share the long game of growing the people who
      come

      after you.
