What it does

Build Status Cache is an agent skill from closedloop-ai/claude-plugins. Skip Phase 7 rebuild when no code changed since Phase 5 build passed. Compares git diff hash against stored hash from last successful build validation. Triggers on: entering Phase 7, checking build status, before final build validation. Returns BUILDCACHEHIT to skip or BUILDCACHEMISS to re-run build-validator.

Its SKILL.md is about 410 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/check_build_cache.sh`).

It sits in Development. It works with Git. The repository describes itself as: Open-source Claude Code plugins for multi-agent software delivery. Plan-first SDLC workflow, code review, LLM quality judges, and self-learning — grounded in your codebase… The licence is Apache-2.0.

When your agent uses it

  • : entering Phase 7
  • Checking build status
  • Before final build validation

Example prompts

  • “/build-status-cache”

Requirements

  • A Bash shell
  • Pre-approved tools (allowed-tools): Bash

Workflow steps

2 steps, taken from the first numbered list in SKILL.md.

  1. After Phase 5 build passes: Stamp the cache
  2. At Phase 7 build check: Check the cache before launching build-validator

What it can do on your machine

Read from SKILL.md and the folder at commit 0e20ac0. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Bash

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Shell), which the agent can run.

    Shell commands in SKILL.md call:

    • bash
    • git

    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

Build Status Cache loads about 411 tokens when it runs. Until then it costs about 84 tokens; SKILL.md has 149 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~84
When it runs · the whole SKILL.md, loaded when a task matches
~411

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.

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Bash

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); the scripts in this folder are not scanned.

Build Status Cache

Check whether a Phase 7 build-validator launch can be skipped because no code has changed since Phase 5 build validation passed.

When to Use

  1. After Phase 5 build passes: Stamp the cache
  2. At Phase 7 build check: Check the cache before launching build-validator

Usage

Stamp (after Phase 5 build passes)
bash
bash ${CLAUDE_SKILL_DIR}/scripts/check_build_cache.sh <WORKDIR> stamp

Output: BUILD_CACHE_STAMPED

Check (before Phase 7 build)
bash
bash ${CLAUDE_SKILL_DIR}/scripts/check_build_cache.sh <WORKDIR>

Interpreting Output

Cache Hit
BUILD_CACHE_HIT

Action: Skip the Phase 7 build-validator launch. Build was already validated and no code changed.

Cache Miss
BUILD_CACHE_MISS
reason: <why the cache is stale or missing>

Action: Run build-validator as normal.

How It Works

The script hashes git diff HEAD output (all uncommitted changes). After Phase 5 passes, this hash is stored. Before Phase 7 runs, the current hash is compared. If Phase 6 (visual QA) made code fixes, the hash changes and build-validator re-runs. If Phase 6 was skipped or made no code changes, the hash matches and build-validator is skipped.
