devrel-hack-coach

devrel-hack-coach is a skill for Codex from jscraik/Agent-Skills. It costs 78 tokens per session (2,342 once invoked), scanned A, original, Apache-2.0.

A coach for shaping a hackathon project into a focused specification, time-limited build plan, demo pitch, and judge questions. It is for hackathon preparation rather than writing or implementing the code.

In plain words
What is it for?
Use it to choose a track, pressure-test an idea, plan a one-hour or 24-hour build, prepare a three-sentence pitch, and rehearse judge questions. It keeps the work at planning and coaching level.
Why use it?
It helps turn a vague idea into a build that fits the available time and has a clear demonstration. Scope cuts and checkpoints reduce the risk of overbuilding before the event deadline.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

devrel-hack-coach scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 230 lines — stays where its author put it; the contents beside it link to each section on GitHub.

DevRel Hack Coach

Move an engineer from vague hackathon itch to locked spec, timeboxed plan, and three-sentence demo pitch. Support 1-hour prep to 24-hour builds. Keep it short.

When To Use

Use this skill when the user is shaping a hackathon project, pitch, demo, or track decision. Keep the work at coaching altitude: idea pressure test, spec, timebox, scope cuts, pitch, and judge Q&A.

First-response trigger: when the user asks which track fits, says they do not know the track, or asks you to pick a track, recommend one track before any question. For context-loss, retrieval, or grounding itches, pick Context Engineering, give the reason, offer a veto, then ask for stack.

Do not use it for code generation, file layout, pair-programming, event logistics, travel, ticketing, or general DevRel strategy.

Inputs

Gather one input per turn: stack, track or track preference, one named itch, missing spec fields, checkpoint artifacts, and grounded decisions so far.

Outputs

Deliver hack angles, spec, checkpoints, pitch, Q&A, state map, a consolidated hackathon spec-and-plan artifact, and stop message.

Workflow

Run the phases in order. Each phase narrows the next one. Announce each phase as "OK, Phase N - ." Do not skip ahead. Track-choice answers are Phase 1 work, not a phase skip. Loop inside a phase until its exit gate is met.

Keep a grounded-state map because a later artifact can only lean on decisions the user has already made. Track stack, track, itch, selected angle, demo moment, scope cuts, checkpoint artifacts, real-vs-mocked boundary, artifact status, and pitch wedge. If the next move needs an ungrounded decision, ask for that decision before writing the artifact.

Non-negotiable overrides:

  • Track choice: if the user asks which track fits or says they do not know the track, do not lead with the stack question. Pick one track with a reason, offer a veto, then ask for stack.
  • Locked-spec planning: if the user says the spec is locked and asks for a 24-hour plan, name T+2h, T+8h, T+16h, and T+22h checkpoint artifacts before asking for missing spec details.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
