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

story-readiness 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 8d 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.

Origin

How it starts

The opening of the file, as written. The whole thing — 355 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Story Readiness

This skill validates that a story file contains everything a developer needs to begin implementation — no mid-sprint design interruptions, no guessing, no ambiguous acceptance criteria. Run it before assigning a story.

This skill is read-only. It never edits story files. It reports findings and asks whether the user wants help filling gaps.

Output: Verdict per story (READY / NEEDS WORK / BLOCKED) with a specific gap list for each non-ready story.


Phase 0: Resolve Review Mode

Resolve the review mode once at startup (store for all gate spawns this run):

  1. If skill was called with --review [full|lean|solo] → use that value
  2. Else read production/review-mode.txt → use that value
  3. Else → default to lean

See .agents/docs/director-gates.md for the full check pattern and mode definitions.


1. Parse Arguments

Scope: $ARGUMENTS[0] (blank = ask user via AskUserQuestion)

  • Specific path (e.g., /story-readiness production/epics/combat/story-001-basic-attack.md): validate that single story file.
  • sprint: read the current sprint plan from production/sprints/ (most recent file), extract every story path it references, validate each one.
  • all: glob production/epics/**/*.md, exclude EPIC.md index files, validate every story file found.
  • No argument: ask the user which scope to validate.

If no argument is given, use AskUserQuestion:

  • "What would you like to validate?"
    • Options: "A specific story file", "All stories in the current sprint", "All stories in production/epics/", "Stories for a specific epic"

Report the scope before proceeding: "Validating [N] story files."


2. Load Supporting Context

Before checking any stories, load reference documents once (not per-story):

  • design/gdd/systems-index.md — to know which systems have approved GDDs
  • docs/architecture/control-manifest.md — to know which manifest rules exist (if the file does not exist, note it as missing once; do not re-flag per story) Also extract the Manifest Version: date from the header block if the file exists.
  • docs/architecture/tr-registry.yaml — index all entries by id. Used to validate TR-IDs in stories. If the file does not exist, note it once; TR-ID checks will auto-pass for all stories (registry predates stories, so missing registry means stories are from before TR tracking was introduced).
  • All ADR status fields — for each unique ADR referenced across the stories being checked, read the ADR file and note its Status: field. Cache these so you don't re-read the same ADR for every story.
  • The current sprint file (if scope is sprint) — to identify Must Have / Should Have priority for escalation decisions

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.
