At a glance

Provides instructions on implementing feature specs or module blueprint commit diffs in a specific codebase.

  • Tasks that involve PRD writing
  • Calls git and python3

What it does

A2ui Implement Feature From Blueprint is an agent skill from a2ui-project/a2ui. Provides instructions on implementing feature specs or module blueprint commit diffs in a specific codebase.

Its SKILL.md is about 540 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Product & Project Management, covering PRD writing. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve PRD writing

Example prompts

  • “Use the a2ui-implement-feature-from-blueprint skill to provide instructions on implementing feature specs or module blueprint commit diffs in a…”
  • “/a2ui-implement-feature-from-blueprint”

Requirements

  • Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit db43065. 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

    Shell commands in SKILL.md call:

    • git
    • python3

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

  • Network

    No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

    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

A2ui Implement Feature From Blueprint loads about 537 tokens when it runs. Until then it costs about 37 tokens; SKILL.md has 194 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~37
When it runs · the whole SKILL.md, loaded when a task matches
~537

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.

A2UI Implement Feature from Blueprint Skill

This skill provides step-by-step instructions on implementing feature specifications and updating codebase module compliance commit hashes.

1. Implementation Workflow

Step 1: Check Codebase Status & Context
  • Open the target codebase's blueprint at blueprints/codebases/<relative_path>/codebase.blueprint.md.
  • Identify the target associated_module and module_blueprint_commit.
  • Check if the codebase needs to catch up to the latest Module Blueprint commit:
    bash
    git diff <module_blueprint_commit>..HEAD blueprints/modules/<associated_module>.blueprint.md
  • If implementing an optional feature blueprint from blueprints/features/<feature_name>.blueprint.md, check its dependencies list first.
  • Verify that terms used in code, documentation and blueprints are consistent with the glossary. If you find deviations, suggest fixes. If you see an important term is used in documentation and/or API, but is missing from the glossary, suggest an update for the glossary.
Step 2: Execute Implementation & Conformance Tests
  • Implement required code changes in the target codebase directory (<relative_path>).
  • Run local unit and conformance tests specified by test_command in codebase.blueprint.md.
Step 3: Update Codebase Blueprint Compliance
  • Open blueprints/codebases/<relative_path>/codebase.blueprint.md.
  • If you brought the codebase up to date with the latest Module Blueprint commit, update module_blueprint_commit to the current commit hash:
    bash
    git log -n 1 --pretty=format:%H blueprints/modules/<associated_module>.blueprint.md
  • If you implemented an optional feature from blueprints/features/, add its name to implemented_features.
Step 4: Validate Blueprints

Verify blueprint consistency across the monorepo:

bash
python3 blueprints/validate_blueprints.py
