bab-ilu: Skill for Claude Code

.claude/skills/prompt/SKILL.md

prompt is a skill for Claude Code from P1-103n1x/bab-ilu. It costs 86 tokens per session (2,546 once invoked), scanned B, original, MIT.

A lens-aware command that creates one structured creative deliverable according to the selected subject area’s rules.

In plain words
What is it for?
It can produce visual-analysis prompts, software design pattern cards, or organized concept notes, depending on the active lens and requested type.
Why use it?
It prevents every subject area from receiving the same kind of output when their useful results differ.

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 B, and why

prompt scanned grade B with 1 finding 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 12d 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.

Asks the agent to reveal its instructionsmediumSystem prompt leakage

Directions to print, repeat or translate the system prompt extract configuration the operator did not intend to expose.

- The output prompt does NOT cite a single signature author — it cites the panel: `[lineage] Warburg panel: [[{panel}]] · AAT: {term} (aat:{id})`

/prompt — Lens-aware deliverable generator

Lens awareness (v2.1)

/prompt is the lens-specific deliverable producer. Each lens declares what "a useful creative output" means for its domain via lens.deliverable_types. The same command name produces three very different artifacts because deliverables are a lens-level value judgment, not a Bab-ilu-level one.

Runtime wiring (shared by every mode):

  1. Resolve the active lens via tools/lens_loader.load_lens(lens_id) — honor --lens <id> when explicitly overridden.
  2. Inject tools.lens_context.active_lens_preamble() at the top of every LLM-facing stage. The lens's prompts.md carries the tone, rubrics, and traps specific to this deliverable form.
  3. Pull tier_0 / tier_1_atom / tier_1_cluster from lens.entity_model — the input wikilink shape and its downstream resolution are all tier-typed, not hardcoded to "aesthetic" or "panel".
  4. Emit exactly one deliverable per invocation, shaped by the first entry of lens.deliverable_types unless the user passes --type <name> to select a different one the lens declared.

Deliverable table

Lens deliverable_types declared in lens.yaml Output shape
aesthetic-warburg [aesthetic, panel] (landed) aesthetic → four-segment labeled prompt (Subject / Style / Composition / Motion) for UI/image/video sub-modalities; panel → Warburg panel-level prompt
engineering-alexander [pattern-card] (proposed) Alexander-style Pattern card: Context → Problem → Forces → Solution → Resulting-context with incident citations as Examples
general-zettelkasten [progressive-summary] (proposed) Three-layer Progressive Summary: bold-highlighted key sentence in layer 1, 3–5 bold fragments in layer 2, one-sentence thesis in layer 3

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.

prompt is a skill published in the GitHub repository P1-103n1x/bab-ilu (11 stars, last pushed 4mo ago), licensed MIT. It adds 86 tokens to every session and 2,546 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it B with 1 finding (asks the agent to reveal its instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
