fix-failed-build

fix-failed-build is a skill for Claude Code, Codex from theonedev/tod. It costs 25 tokens per session (884 once invoked), scanned A, original, MIT.

A procedure for investigating and fixing a failed OneDev build, where OneDev is a service for hosting code and running automated builds.

In plain words
What is it for?
Use it when given a failed-build reference and a matching repository checkout, with no issue or pull-request context available.
Why use it?
It provides a defined sequence for identifying the failed build and checking the current project and branch before changing code. It stops when required information or a safe starting condition is missing.

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

fix-failed-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 6d 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.

Fix a failed OneDev build

Inspect the failed build from the user's prompt and implement the fix in the current checkout.

Prerequisites

  • tod is installed and configured.
  • The current repository belongs to the same OneDev project as the failed build.
  • The current checkout is on a branch.

Stop on error

Run the workflow sequentially. On any unrecoverable command failure, missing required output, or failed precondition, report the command and error and stop. Do not continue the workflow.

Workflow

Given a required <build-reference> from the user prompt (e.g. 123, #123, myproject#123, or PROJ-123):

  1. Resolve the build reference. Use the <build-reference> from the user prompt. If the prompt does not provide a build reference, stop and ask for the failed build reference.

  2. Verify the checkout context. Do not prepare or switch checkouts.

    Confirm that the current checkout is on a branch:

    git symbolic-ref --short HEAD
    

    If the command fails or reports a detached HEAD, stop and report that the workflow requires a branch checkout.

    Confirm the current project:

    tod project current
    

    Save the output as <current-project>.

  3. Gather and examine build evidence. Run:

    tod build get <build-reference>
    tod build get-log <build-reference>
    

    Read the build detail and log content carefully to identify the failure. Verify that the build belongs to <current-project> using the project field in the build detail when present. If the build detail indicates a different project, stop and report the mismatch.

  4. Assess and fix the failure.

    • If the log contains a statement like Dependency build is required to be successful but failed: <dependency-build-reference>, get the dependency build detail. If the dependency build is cancelled, do not investigate or fix it; report that the relevant dependency build was cancelled. If its commit hash is the same as the current build, investigate or fix the dependency build failure instead; repeat this process for same-commit dependency build failures. If the dependency build's commit hash differs from the current build, conclude that the current build failure is caused by this dependency build.
    • If the log contains a statement like [<report-name>]: found problems with severity <severity-level> or higher, fetch the referenced problems report:
      tod build get-code-problems <build-reference> <report-name> <severity-level>
      
      Problems may point to workspace files, 1-based line ranges, or non-workspace artifacts used by the project.
    • If the log contains [<report-name>]: <count> not passed test cases, inspect the report and any relevant artifacts it references:
      tod build get-unit-test-report <build-reference> <report-name>
      tod build get-unit-test-report <build-reference> <report-name> --artifact <artifact-path> > <output-file>
      
    • Inspect referenced workspace files as necessary. Inspect .onedev-buildspec.yml when job configuration may be involved, and run below command to get its schema if you need to modify it:
      tod build get-spec-schema
      
    • If useful, inspect changes since the previous successful build:
      tod build get-changes-since-success <build-reference>

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.

fix-failed-build is a skill published in the GitHub repository theonedev/tod (14 stars, last pushed today), licensed MIT. It adds 25 tokens to every session and 884 once invoked, about $0.0001 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 2026-08-30.
