gate-build

gate-build is a skill for Claude Code, Codex from Obsidian-Owl/specwright. It costs 51 tokens per session (808 once invoked), scanned A, original, MIT.

A build-and-test check that runs the project's configured commands in order. Tiers are separate levels such as compilation, ordinary tests, integration tests, and smoke tests.

In plain words
What is it for?
It runs build, test, integration-test, and smoke-test commands when configured, stops after a failure, captures evidence, and reports pass, fail, warning, or skip results.
Why use it?
It shows whether the code builds and tests pass, and makes unconfigured or skipped checks visible instead of hiding them.

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

gate-build 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 4d 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 — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Gate: Build

Goal

Confirm the codebase compiles and tests pass across all configured tiers. This is the most basic gate — if the code doesn't build or tests don't pass, nothing else matters.

Inputs

  • {projectArtifactsRoot}/config.json -- commands.build, commands.test, commands.test:integration, commands.test:smoke
  • {repoStateRoot}/work/{selectedWork.id}/workflow.json -- selected work unit for evidence path

Outputs

  • Evidence file at {workDir}/evidence/build-report.md
  • Gate status update in the selected work's workflow.json: PASS, FAIL, WARN, or SKIP
  • Console output showing results inline (users see findings, not just badges)

Constraints

Tiered Execution (LOW freedom):

Run tiers in execution order: commands.buildcommands.testcommands.test:integrationcommands.test:smoke. Each tier runs only if the previous tier passes (any tier failure stops further execution).

  • If a tier's command is null or not configured, that tier produces SKIP. Emit an INFO note for each unconfigured tier — visibility rule: display the unconfigured tier name so users know what was skipped.
  • If all tier commands are null/unconfigured, gate status is SKIP.
  • Timeout: 5 minutes per command. If exceeded, status is ERROR.

Per-Tier Verdicts (LOW freedom):

Tier Failure verdict
commands.build FAIL
commands.test FAIL (test failure = FAIL)
commands.test:integration FAIL (integration failure = FAIL)
commands.test:smoke WARN (smoke produces WARN on failure — charter exception: quality gates default to FAIL: smoke tests validate optional end-to-end paths; degraded smoke is advisory, not blocking)

Unconfigured tier = SKIP.

Evidence (LOW freedom):

Follow protocols/evidence.md. Evidence starts with a tier layout header summarizing configured tiers and their run order. Each tier produces its own evidence section containing: command executed (capture command run), exit code, stdout/stderr output, and duration (elapsed wall time). Per-tier sections are written regardless of tier outcome.

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.

gate-build is a skill published in the GitHub repository Obsidian-Owl/specwright (9 stars, last pushed 4mo ago), licensed MIT. It adds 51 tokens to every session and 808 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
