At a glance

Build a target project into an opentaint project model. An agent skill from seqra/opentaint.

  • Works in 7 steps: Reset the output → Identify the build → Enable all modules → …
  • A fresh opentaint project model needed
  • SKILL.md covers Inputs, Workflow, Output and Constraints
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Build Project is an agent skill from seqra/opentaint. Build a target project into an opentaint project model. Use whenever a fresh opentaint project model needed

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/java.md`).

It sits in Security, covering Static analysis and SAST. The repository describes itself as: The open source taint analysis engine for the AI era. A formal dataflow analysis tool you can customize and self-host, built so AI agents drive your application security analysis… The licence is Apache-2.0.

When your agent uses it

  • A fresh opentaint project model needed
  • Tasks that involve Static analysis and SAST

Example prompts

  • “/build-project”

Workflow steps

7 steps, taken from the step headings in SKILL.md.

  1. Reset the output
  2. Identify the build
  3. Enable all modules
  4. Autobuilder — the primary path
  5. Manual build + opentaint project — last resort
  6. Verify
  7. Escalate

What it can do on your machine

Read from SKILL.md and the folder at commit f945f92. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Build Project loads about 1.1k tokens when it runs, and up to ~1.7k if it reads all its reference files. Until then it costs about 30 tokens; SKILL.md has 626 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~30
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Skill: Build Project

Turn a target project into an opentaint project model: run the project's build, resolve its dependencies if needed. The build tool, toolchain, and scope flags are language-specific — detect the target language from the project's build files, then read the matching references/<language>.md and follow its numbered steps, which key to the ones below.

Inputs

Provided by the caller, fall back to the default value when omitted. Ask back only when a required input is missing and has no sensible default

  • project-root (optional) — root of the target project. Opentaint keeps all analysis artifacts under the fixed <project-root>/.opentaint/ directory, so every .opentaint/... path below resolves there. Default: current directory
  • build-hints (optional) — anything known about how this project builds: required toolchain version, modules/profiles to enable, project-specific build approach and so on

Workflow

1. Reset the output

Delete any existing .opentaint/project first, so files from an old model can't bleed into the new one

2. Identify the build

Determine how the project builds — its build tool, or whether it ships pre-compiled artifacts

3. Enable all modules

Re-enable every module the project disables so their code lands in the model, then build with them included. Enabling a disabled module is a config edit, not a source change, so the model still represents the current commit. If a specific module cannot be made to compile after reasonable effort, exclude only that one. Report which modules were enabled and which (if any) were excluded.

4. Autobuilder — the primary path
bash
opentaint compile <project-root> -o .opentaint/project

opentaint compile runs the project's real build, so it resolves the full dependency graph and the actual module reactor automatically — no hand-listing of dependencies or scope. Set the build toolchain the project needs first. Use this path almost always.

Feedback loop: a failure here is almost always a fixable build problem, not grounds to leave this path — and the autobuilder's wrapper message is terse, so don't judge fixability from it. Reproduce the project's own build directly to surface the real error, fix it, then re-run opentaint compile.

5. Manual build + opentaint project — last resort

Only when the project's own build cannot be made to pass at all, build the artifacts by hand, then create the model from them with opentaint project, restricting analysis to project code. It's required to show the analyzer which code belongs to the project and which to third-party packages. Take the scope roots from what the code actually declares, not the build config or the folder layout. Verify final list of methods carefully, it's very important to list ALL third-party packages.

6. Verify

.opentaint/project/project.yaml exists, non-empty, and its module/scope entries cover every root the project's own code declares. For a multi-module project, confirm the expected module count is present. Make sure, that dependencies at .opentaint/project/dependencies resolved and downloaded correctly.

7. Escalate

When the build won't converge after ~3 fixes → report non-convergence and leave the build stage pending, for the orchestrator to intervene.

Output

Short and concise report of what was done

Artifacts:
  • .opentaint/project/ — the opentaint project model
Summary:
  • model path and (for a multi-module project) the module count it covers
  • the language-specific build fields defined by the selected reference, with the values used by the successful build
  • how the model was built (autobuilder or manual), and any build config the skill changed to make it build (e.g. re-enabled modules)
  • exact build command and arguments if opentaint project was used
  • if the build did not converge: that it is left pending, with the blocking error and your fix attempts

Constraints

  • Write only the project model under .opentaint/project, don't produce any other files. This skill does not write any tracking state, only return info per Output
  • The model is generated by opentaint, never hand-edit project.yaml or anything under the model dir. To change what's analyzed, fix the command and rebuild
