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

create-internal-feature-announcement 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 10d 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 — 163 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Internal feature announcement (IFA) writer (pm-brain)

Produce 04-internal-feature-announcement.md by filling the IFA template from the PRD pack (01-03-) and any extra sources the user names. Content is internal only; do not copy confidential customer identifiers into examples unless the user explicitly allows it.

Repo convention: Feature hub paths, skipping steps, and the skills table — see 02-templates/README.md (Feature hub convention, Skipping steps, Cursor skills).

This skill assumes a PRD pack exists; if 02-product-requirements.md and 03-success-metrics.md are missing, tell the user to run create-prd first or provide equivalent source paths.

Step 0: Locate the feature hub

  1. Ask for the PROJECT Jira key (PROJECT-abcde) or the path to an existing feature hub folder.
  2. Resolve the feature-hub folder: projects/{PROJECT-KEY}-{slug}/.
    • If only the key is given, list projects/ and match the PROJECT-{KEY}-* directory.
    • If multiple match, show them and ask which one.
  3. Confirm the PRD pack exists in that folder: 01-product-brief.md, 02-product-requirements.md, and 03-success-metrics.md. If any are missing, tell the user to run create-prd first or provide explicit paths to equivalent docs.

Output

Save the deliverable to:

projects/{PROJECT-KEY}-{slug}/04-internal-feature-announcement.md

If the file already exists, ask whether to overwrite, create a dated backup, or choose a different name.

When to use this skill

  • Aligning internal comms before or after launch
  • Preparing Slack #internal-feature-announcement copy and internal FAQ stems
  • Handing off facts to support via the IFA before a customer-facing article

What you'll need

Critical inputs (collect in Step 1 if missing):

  • Feature hub with 01-product-brief.md, 02-product-requirements.md, 03-success-metrics.md
  • Roadmap / release — Alpha, private beta, GA (or explicit TBD)
  • Key contacts — PM, EM, PMM (names or [PLACEHOLDER])

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.
