am-command-build

am-command-build is a skill for Claude Code, Codex from sampleXbro/agentsmesh. It costs 18 tokens per session (183 once invoked), scanned A, original, MIT.

A workflow for completing software tasks in small increments. It uses test-driven development (writing a failing test before implementation), then builds, tests, verifies, commits, and updates the task plan.

In plain words
What is it for?
Use it to implement the next pending task from a development plan. It covers loading relevant code, writing tests, implementing the smallest change, running the test suite and build, and committing the result.
Why use it?
It keeps each change tied to acceptance criteria and checks for regressions before moving on. When something fails, it directs the workflow toward debugging and recovery.

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

am-command-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 1mo 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.

What it actually says

Invoke the agent-skills:incremental-implementation skill alongside agent-skills:test-driven-development.

Pick the next pending task from the plan. For each task:

  1. Read the task's acceptance criteria
  2. Load relevant context (existing code, patterns, types)
  3. Write a failing test for the expected behavior (RED)
  4. Implement the minimum code to pass the test (GREEN)
  5. Run the full test suite to check for regressions
  6. Run the build to verify compilation
  7. Commit with a descriptive message
  8. Mark the task complete and move to the next one

If any step fails, follow the agent-skills:debugging-and-error-recovery skill.

Changes

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.
