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

packmind-update-playbook 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 9d 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.

How it starts

The opening of the file, as written. The whole thing — 144 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Update Playbook

Run "packmind-cli --version" to get the current cli installation.

Find the highest version at or below the cli version in this list:

  • 0.21.0
  • 0.23.0 Remember this value as $PACKMIND_CLI_VERSION for the rest of the skill.

Evaluate the user's intent against existing Packmind artifacts (standards, commands, skills) to identify what needs creating or updating. Produce a structured change report, then apply approved changes using the playbook CLI workflow.

⚠️ MANDATORY WORKFLOW — This skill defines a strict sequence: Understanding Your Request → Summarizing Changes → Analyzing Playbook → Change Report → Applying Changes. Do NOT skip steps or edit artifact files directly. Even for a single-line change, follow every step. The workflow ensures changes are reviewed, approved, submitted, and propagated correctly.

Understanding Your Request

STOP. This phase runs FIRST, before anything else. No file reads, no CLI commands, no subagents until this gate passes.

Analyze the user's input and conversation context to determine intent:

Case A: No prior conversation / empty input

The skill was invoked standalone with no context. Ask:

"What Packmind artifact do you want to modify? For example: a standard (coding rule/convention), a command (multi-step workflow), or a skill (specialized capability). Please describe what you'd like to change."

BLOCK — do not proceed until the user responds.

Case B: Explicit intent found

The user explicitly asked to update, add, fix, or change a Packmind artifact. Extract an intent summary:

  • Target artifact(s): which standard(s), command(s), or skill(s) to modify (or "new")
  • Kind of change: create or update
  • Specifics: any details the user provided about the change

Proceed to Summarizing Changes with this validated intent.

Case C: Opportunity detected from conversation

The conversation reveals a playbook update opportunity — e.g., a convention was established, a pattern emerged, a workflow was changed, or a known artifact is now stale — but the user did not explicitly ask for a playbook update. Summarize the opportunity and ask:

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.
