paul:apply

A command that carries out an approved development plan task by task, with checks and pauses when a human decision or verification is needed.

In plain words
What is it for?
It executes tasks in sequence, verifies each task, records decisions, waits for human approval or action when required, and reports what remains next.
Why use it?
It turns an agreed plan into tracked work while keeping the user involved at important checkpoints.

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

paul:apply 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 3d 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

When to use: After PLAN phase complete and plan is approved.

Executes tasks in sequence, pauses at checkpoints for user input, reports completion.

<execution_context> @/.claude/paul-framework/workflows/apply-phase.md @/.claude/paul-framework/references/checkpoints.md </execution_context>

@.paul/STATE.md

Execute tasks sequentially. For each task:

  • Read task definition

  • Run verification
  • Confirm done criteria

checkpoint:decision

  • Present decision context and options
  • Wait for user selection
  • Record decision
  • Continue execution

checkpoint:human-verify

  • Present what was built
  • Present verification steps
  • Wait for "approved" or issue description
  • If issues: address and re-verify
  • Continue execution

checkpoint:human-action

  • Present required action
  • Wait for "done" confirmation
  • Continue execution

<success_criteria>

  • All tasks executed
  • All checkpoints handled
  • User informed of completion
  • Next action clear (run /paul:unify) </success_criteria>

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.
