packmind: Skill for Claude Code

.claude/skills/agentic-feature-framing/SKILL.md

agentic-feature-framing is a skill for Claude Code from PackmindHub/packmind. It costs 134 tokens per session (1,265 once invoked), scanned A, original, Apache-2.0.

A planning skill that defines what a feature will include, what it will exclude, and how completion will be judged before design or coding starts. It writes these boundaries and acceptance criteria into a feature charter.

In plain words
What is it for?
It is for turning a rough request, ticket, or idea into a written feature scope with non-goals and acceptance criteria.
Why use it?
A clear scope gives later coding agents rules for handling ambiguity and prevents them from quietly deciding what the feature should mean. It also shows whether the work is suitable for one implementation run or should be split.

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

agentic-feature-framing 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.

How it starts

The opening of the file, as written. The whole thing — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Feature framing

You are settling what is being built. Not how. The output is one file: .claude/features/<slug>/charter.md, from .claude/pipeline/charter.template.md.

Why this exists

Two reasons, and the second is the one that gets forgotten.

Scope and criteria are the escalation ladder. Downstream, an orchestrator dispatches cheap subagents that cannot ask you anything. When one of them hits an ambiguity, it walks an escalation ladder: does an acceptance criterion answer this, does a decision entry answer it, is it a new decision inside scope — and only if all three fail does it stop and wait for a human.

Every rung of that ladder is something you write here or in the design session. A charter that is vague about scope does not produce a flexible pipeline; it produces one that halts constantly, or worse, one whose subagents quietly decide for themselves.

And this phase, with 1b, is how the size of the work becomes visible. Not so that units can be planned — they never are — but so that the decision to hand this to the orchestrator in one run, or to cut it into several, is made deliberately and before anything is built. That verdict is written at the close of the design session, into the charter's Size and sessions. What you owe it here is a coarser read: whether this is one feature at all.

Hard rules

  • Write no code. Not an example, not a sketch, not a type definition.
  • Edit no file but the charter.
  • Do not design. "We could use a queue for this" is a decision-session question. If the user offers implementation, write down the requirement it implies and move on.
  • Do not accept the first plausible framing. The first answer to "what are we building" is almost always the solution the user already has in mind, not the problem.

How to run the conversation

Start with the problem, and stay there longer than feels natural. Who hits this today, how often, what do they do instead. You are looking for the sentence that makes the acceptance criteria obvious.

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.
