This is the fast go/no-go call for technical sourcers: in the two minutes after you open a developer's GitHub profile, decide whether it clears the bar to invest research and outreach time for one specific open role. It is written for in-house recruiters, sourcers, and founders doing their own hiring. It gives you named dimensions, numeric thresholds, and a documented note on how each signal lies, so that two people grading the same profile reach the same decision.

This guide covers one narrow judgement: research-now, park, or skip. It deliberately does not cover whether a profile is gamed or borrowed, or whether the person will reply. Those are separate reads. Here the only question is worth-my-time-for-this-role, and the whole point is to answer it fast and defensibly.

## What the triage read decides, and what it does not

The triage read produces one label for one profile against one role: research-now, park, or skip. It is a two-minute filter that protects an expensive step, not the deep evaluation itself.

Practitioners report spending 20 to 30 minutes researching a single GitHub candidate before sending any outreach. That is too much to spend on a profile that was never a fit. The triage read exists so you spend those minutes only where they pay off. Everything in this guide is tuned to keep the read under two minutes without letting the two loudest signals - stars and contribution-graph green - drive the call.

Keep three activities separate in your head:

- **Triage (this guide):** under two minutes, produces research-now / park / skip.
- **Deep research:** 20 to 30 minutes, only for research-now profiles.
- **Outreach:** a later step, referencing specific work, only after research.

> **Rule:** The two-minute rule protects the twenty-minute step
>
> Triage and research are different jobs. If you find yourself reading commit history line by line, you have left triage and started research on a profile you have not yet decided to research.

## The dimensions that matter, and how each one lies

Five dimensions carry the call, and every one of them has a documented way of misleading you. Score the signal, then ask what it looks like when it is false before you trust it.

The sources converge on what is predictive and what is noise. Recent commits, pinned repos, language mix, and README quality matter more than follower count or total repo count. Ownership signals - original repos, maintainership, release history, visible technical direction - and collaboration evidence - merged pull requests, issue discussions, code reviews, organization work - are the load-bearing signals. Stars and followers add context but should never carry the evaluation on their own.

Here is what each dimension proves and how it lies:

- **Contribution recency and consistency.** Proves the person is actively building. Lies when the graph is filled by backdated empty commits; the platform never checks the date against a clock.
- **Ownership.** Proves they can start and steer real work. Lies when a profile is a wall of forks read as authored projects.
- **Collaboration.** Proves they ship inside teams. Lies through squash-merges, which credit only the merger and opener and erase other contributors.
- **Substance of contributions.** Proves the work is real. Lies when recent activity is only README or typo edits.
- **Stars and followers.** Add context on reach. Lie constantly; a viral toy repo or a well-connected account can mask thin code.

#### How to weight GitHub signals

1. **Ownership and collaboration** - Original repos, maintainership, release history, merged upstream pull requests - these carry the call.
2. **Substance and recency** - Real diffs within the last 3 to 6 months, not README or typo edits.
3. **Language and README quality** - Corroborates the stack and signals communication.
4. **Stars and followers** - Supporting context only; never decides the outcome.

*Weight ownership and collaboration highest, treat stars and followers as supporting context only.*

The insight underneath the whole rubric: the contribution graph is timestamps, not proof. Because Git accepts any author date, green density is trivially forged, and free tools distribute realistic patterns. That single fact is why a defensible rubric weights merged-upstream pull requests over graph fill.

**82% - Share of contributions in private repositories**

You are grading roughly 18% of the work, so absence of public code is uninformative, not disqualifying.

## Ownership versus fork: the one check that separates authors from collectors

A fork is not authorship, and telling them apart is the highest-value 30 seconds in the whole read. Open the pinned repos and look for the forked-from banner before you credit anyone with a project.

When you view a forked repository, the upstream repo is named below the fork, with text like "forked from github/docs" outlined. That banner is your first tell. GitHub's own rule is that issues and pull requests appear on your contribution graph only if opened in a standalone repository, not a fork, and commits count only if made in a standalone repo. So in theory forks do not inflate the graph.

In practice, attribution is inconsistent even inside GitHub. Community threads report that commits to a fork's default branch can still surface on the contributor's graph, even without being merged upstream. This ambiguity is exactly why counting the green fails. The harder, honest signal is a merged pull request into the upstream project.

> **Watch out:** Squash-merges erase real contributors
>
> When a pull request is squash-merged, GitHub credits only the merger and the opener. A genuine contributor can show no graph credit for real, merged work. Read the merged pull request list, not just the graph, or you will skip strong people for a platform artifact.

To confirm original work in under a minute:

1. Open the top pinned repos.
2. Look for the forked-from banner. Forks are collections, not authorship.
3. In non-fork repos, check for releases and a real commit history from the person.
4. For contributions to big projects, open the merged pull request list rather than trusting graph squares.

## The scarcity math that sets your bar before quality does

Your triage bar is not fixed. It moves with how many candidates the market actually holds for the role's stack and location, and that supply can be brutally thin. Check the pool size before you tighten filters, or you will filter an empty room.

In Refolk's index of professional profiles, the language you are hiring for changes the game entirely. The US pool for Python-listing software engineers is 55,821. For Go it is 2,767. For Rust it is 606. A Rust search returns roughly one candidate for every 92 Python candidates in the same market.

**Table B - US software engineer pool by language skill (Refolk's index)**

| Skill | Engineers | Multiple of Rust |
| --- | --- | --- |
| Python | 55,821 | 92.1x |
| Go | 2,767 | 4.6x |
| Rust | 606 | 1.0x |

Counts are from Refolk's index for US profiles with the title "Software Engineer"; multiples are derived against the Rust baseline.

Geography compresses the pool again. Python engineers number 55,821 in the US against 2,732 in Germany, a difference of roughly twentyfold.

**Table A - Python software engineer supply, US versus Germany (Refolk's index)**

| Country | Matching engineers | Share of US |
| --- | --- | --- |
| US | 55,821 | 100% |
| Germany | 2,732 | 4.9% |

Counts are from Refolk's index (title "Software Engineer" plus skill Python); the ratio is derived, with the US pool about 20.4x Germany.

The practical rule: on a thin stack or a narrow geography, drop the triage bar or widen the search, because absence of candidates is not the same as absence of quality. A local-only search on a mid-tier language can starve a pipeline before quality filtering even begins.

> On a stack with 606 candidates in the whole country, your triage bar is a luxury you cannot always afford.

The framing search is where you build the pool, and doing it in plain English rather than juggling qualifiers removes most of the friction this section describes.

I ran this search: `Senior Rust engineers in the US who maintain their own open-source crates, not just fork them.` - [see the full result list](https://www.refolk.ai/s/6etcf7haxy).

*Returns maintainers with original crates and upstream ownership, already filtered past the fork-collector problem this guide warns about.*

## The triage procedure

Run the same seven steps in the same order every time. Steps 3 through 6 are the actual two-minute read; steps 1, 2, and 7 sit around it.

#### The two-minute triage read

1. **Frame the role first** - Before opening any profile, fix the primary language, location, and seniority for one specific open role. Done looks like a one-line target you can hold every profile against.
2. **Run a filtered search** - Combine location, language, followers, and repos qualifiers in GitHub user search to cut millions of accounts to a shortlist of 30 to 50. Done looks like a targeted list, not ten thousand irrelevant results.
3. **Read pattern before polish** - Glance at the contribution graph for recency and consistency, not raw volume, as a fast first-pass keep or drop. Done looks like a provisional call you have not yet trusted.
4. **Check ownership versus fork** - Open the pinned and top repos and look for the forked-from banner, merged upstream pull requests, releases, and maintainership. Done looks like confirmed original work rather than a wall of forks.
5. **Score substance** - Confirm activity within the last three to six months and that contributions are real diffs, not README or typo edits. Done looks like a substantive-versus-cosmetic verdict.
6. **Assign a triage decision** - Label the profile research-now, park, or skip based on role fit and the signals you scored, in under two minutes total. Done looks like a defensible label tied to this specific role.
7. **Draft referenced outreach for research-now only** - For profiles that clear the bar, later draft outreach that references a specific repo or pull request. Done looks like a message no other candidate could receive unchanged.

Note one honest disagreement in the sources. Some say lead with the contribution graph as the quickest first pass; others argue repository-based sourcing produces more relevant results than profile-first searching. This procedure resolves it by using the graph only as a provisional glance in step 3 and forcing repo-level verification in steps 4 and 5 before any decision. The graph opens the read; it never closes it.

#### Where the two minutes go

1. **Graph glance** - Recency and consistency, provisional keep or drop, ~30 sec.
2. **Ownership check** - Fork banner, merged upstream pull requests, releases, ~30 sec.
3. **Substance check** - Real diffs within 3 to 6 months, not typo edits, ~30 sec.
4. **Decision** - Research-now, park, or skip against this role, ~30 sec.

*The graph opens the read as a fast glance, but ownership and substance close it.*

### Reading the decision: research-now, park, or skip

The label is a function of two things: fit to the framed role, and strength of verified signals. A matrix keeps it honest.

#### The triage decision matrix

Horizontal axis runs from Weak fit to the role to Strong fit to the role. Vertical axis runs from Thin or unverified signals to Strong verified ownership and substance.

| Quadrant | What it means |
| --- | --- |
| Strong signals, weak fit | Park - real engineer, wrong role; save for a future req. |
| Strong signals, strong fit | Research-now - spend the 20 to 30 minutes. |
| Thin signals, weak fit | Skip - nothing contradicts and nothing supports for this role. |
| Thin signals, strong fit | Park and verify - fit looks right but public evidence is thin; confirm elsewhere before spending research time. |

*Plot verified signal strength against fit to the framed role to land the label.*

Skip means skip for this role, not blacklist. Because roughly 82% of activity is private, thin public evidence pushes a profile to park, not skip, whenever the framed fit looks right. You skip only on a contradicting signal, never on absence alone.

## How the triage read goes wrong

The read fails in eight documented ways, and every one is a signal trusted past the point where it stays true. Learn the false positive and the fast check for each.

> **Watch out:** Every loud signal on GitHub has a way to lie
>
> The two signals that catch the eye first - a dense green graph and a high star count - are the two most easily faked or misread. Treat visual loudness as a reason to verify, not a reason to trust.

- **Green graph read as productivity.** False positive: a dense graph built from backdated empty commits. Check: open the repos behind the dots and look for real diffs, not "update" or "wip" one-liners.
- **Fork counted as ownership.** False positive: a profile of forks read as authored projects. Check: the forked-from banner and whether pull requests were merged upstream.
- **Stars or followers read as skill.** False positive: a viral toy repo or a well-networked account with thin code. Check: treat as supporting only; stars never carry the call.
- **Empty profile read as weak engineer.** False positive: strong closed-source or management-track engineers with little public code. Check: with 82% of activity private, do not skip on sparseness.
- **Location filter read as ground truth.** False positive: zero results because the field is blank, not because no one qualifies. Check: location matches only filled-in profiles.
- **Language qualifier read as their real stack.** False positive: it matches only public repos they own, missing their primary work language. Check: corroborate with pinned repos and README tech.
- **Recency without substance.** False positive: recent activity that is only README or typo edits. Check: confirm contributions are substantive within 3 to 6 months.
- **Squash-merge erasure.** False negative: a real contributor shows no credit because a pull request was squashed. Check: read the merged pull request list, not just the graph.

Two of these deserve extra weight because they are structural, not careless. First, the graph is forgeable by design; free tools exist purely to generate realistic fake patterns. Second, GitHub's own fork and squash rules mean the graph both over-credits forks and under-credits squashed contributors. Between those two, "count the green" is the single most common and most costly triage mistake.

## Search filters and their blind spots

GitHub user search filters on profile-level fields: location, programming language, follower count, repository count, and join date via the created qualifier. Knowing these is the difference between ten thousand irrelevant results and a shortlist of fifty. But two of them have blind spots that quietly hide real candidates.

The language qualifier matches repositories a user owns, not their private or work code. So an engineer whose day job is in Go but whose public repos are in Python will not surface on a Go language filter. And the location filter works only if the user filled in the field; a blank field returns no match even when the person qualifies. Both blind spots produce the same silent failure: an empty result set that looks like scarcity but is really a filter limitation.

The habit that fixes this: never let a filtered search be your only pass. Corroborate the language against pinned repos and README tech, and widen location to region when a city returns thin. When you frame a search in plain English instead of stacking qualifiers, [Refolk](/) handles the corroboration across public GitHub, LinkedIn, and the open web, so a blank location field or a mismatched language tag does not silently drop a qualified person.

## Outreach lift, and why the numbers are directional

Referencing specific work in outreach lifts reply rates, and the lift is large and consistent across sources - but every figure is vendor-published, so treat the exact numbers as directional. The mechanism is what matters: a message that names a real repository or pull request cannot be sent to anyone else unchanged.

**Table C - Reported outreach reply rates by personalization tier (public vendor benchmarks)**

| Tier | Reply or open rate | Source |
| --- | --- | --- |
| Generic InMail | 3 to 5% reply | vendor blog |
| Template plus first name | 5 to 8% reply | vendor blog |
| Specific-reference personalized | 15 to 25% reply | vendor blog |
| Personalized subject line | 46% open vs 35% generic | vendor analysis of 5.5M emails |

All figures are vendor-published, not peer-reviewed. The direction is reliable; the decimals are not.

This is why triage feeds outreach. You only earn the 15 to 25% tier by having something specific to reference, and you only find something specific by doing the ownership and substance checks in the first place. A profile you triaged carefully hands you the outreach hook for free.

**Referenced outreach skeleton for a research-now profile**

```
Hi [first name],

I came across your work on [specific repo] - the [specific feature or merged PR] stood out because [one concrete reason tied to the role].

I'm hiring a [role] where that exact kind of [ownership / infra work / library design] is the core of the job.

Worth a short conversation? Happy to share the details either way.

[your name]
```

*Replace the italic parts with the actual repo, pull request, and role before sending. If you cannot fill the specific reference, the profile was not researched enough to send.*

## Before you call a profile triaged

Run this checklist on any profile before you commit it to a label. It is the difference between a defensible decision and a guess.

#### Triage completeness check

- [ ] I framed the role's primary language, location, and seniority before opening the profile.
- [ ] I read the contribution graph for recency and consistency, not raw volume.
- [ ] I opened the pinned repos and confirmed original work exists, not just forks.
- [ ] I checked the forked-from banner on anything I credited as authored.
- [ ] I found at least one merged upstream pull request or release for collaboration or ownership claims.
- [ ] I confirmed activity within the last 3 to 6 months is substantive, not README or typo edits.
- [ ] I did not let stars or follower count carry the decision.
- [ ] I did not skip solely because public code is sparse.
- [ ] I assigned research-now, park, or skip tied to this specific role, in under two minutes.

## Keeping the read current

The rubric holds, but the platform underneath it shifts, so re-check the mechanisms rather than memorizing today's numbers. GitHub surpassed 180 million developers and 630 million repositories, with 36.2 million new developers joining in a single year, so pool sizes and search noise both keep growing.

Two things to re-verify on a cadence. First, the fork and squash attribution rules: GitHub's docs and community threads disagree, so before you rely on a graph square, re-confirm what currently counts by checking the docs page on contributions and forks. Second, your stack scarcity: pool sizes like the 55,821 Python versus 606 Rust split move as the market moves, so re-pull the counts for your live roles before you set a triage bar. The method survives; the thresholds are inputs you refresh, not facts you carve in.

The final discipline is separation. Triage answers worth-my-time. It does not answer is-this-gamed or will-they-reply. Keep those reads distinct, run this one under two minutes, and the expensive research time lands only where it earns its keep.

## Frequently asked questions

### How long should evaluating one GitHub profile take?

The triage read itself should take under two minutes: pattern, ownership check, substance check, decision. That is deliberately separate from the 20 to 30 minutes practitioners report spending to research a single candidate before outreach. You only spend that deeper time on profiles the two-minute read labels research-now, so the fast call protects the expensive step.

### Can you trust the GitHub contribution graph?

No, not on its own. Git accepts any GIT_AUTHOR_DATE value, so a commit can be backdated to any day and turn a square green, and free tools distribute realistic fake patterns. Use the graph only as a first-pass recency and consistency glance, then verify with real diffs, merged upstream pull requests, and release history behind the dots.

### Should I skip a developer with a nearly empty GitHub profile?

Not by default. Around 82% of contributions happen in private repositories, so an empty public profile is uninformative rather than disqualifying, especially for closed-source or management-track engineers. Skip only when a signal actively contradicts the role, never on absence of public code alone. If public evidence is thin, verify seniority elsewhere before ruling anyone out.

### Do stars and followers indicate engineering quality?

They are supporting signals only and must never carry the evaluation. A viral toy repo or a well-networked account can show high stars and thin code, while a strong engineer with private work shows almost none. Weight ownership and collaboration evidence, merged pull requests, maintainership, and release history, far above star or follower counts.

### Why do forks confuse GitHub profile evaluation?

A profile can be full of forks that read as authored projects, but a fork is flagged with a forked-from banner below the name. GitHub's own rules say contributions count only in standalone repos, yet community reports show fork default-branch commits still surfacing on graphs. That inconsistency is exactly why you count merged upstream pull requests rather than trusting the green graph.
