Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00034 | $0.04717 |
| Opus 5 | $0.00017 | $0.02358 |
| Sonnet 5 | $0.00007 | $0.00943 |
| Haiku 4.5 | $0.00003 | $0.00472 |
Grade A, and why
tp-plan-audit 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 5d 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 — 320 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Plan Audit
Three-layer verification that plan.md is consistent with its upstream design documents.
| Layer | What | Catches |
|---|---|---|
| Script | Deterministic structural checks | Missing fields, uncovered modules/interfaces, phase count drift, nonexistent files |
| Council | Engineering triad (torvalds, ada, feynman) | Semantic coverage gaps, ordering errors, interface spec drift, buildability issues, test adequacy |
| Collation | Merged findings presented to user | Everything, deduplicated and categorized |
Arguments:
{design-name}(required) — must match an existing directory underthree-pillars-docs/tp-designs/.--spike(optional) — spike mode. Expects Hypothesis/Try/Evaluate task format instead of File/Test/Red/Green. Skips detailed-design.md requirement. Adjusts council prompts for experiment quality review.--light(optional) — light weight-class mode (seeskills/_shared/weight-class.md). Audits a collapsed design.md + thin plan.md pair: detailed-design.md is not required, the council runs one merged conceptual+plan pass instead of the design-audit + plan-audit pair, and divergentweight-classfrontmatter is a hard ERROR. Task fields stay File/Test/Red/Green (light is production work).--auto(optional) — autonomous mode. Auto-resolves findings by accepting council recommendations, applies plan.md fixes without user confirmation, logs each resolution todecisions.md. Seeskills/_shared/auto-mode.mdfor convention. Composable with--spike.

Steps
- Run first-run preflight per skills/_shared/first-run.md.
Step 1: Validate and locate artifacts

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.

tp-plan-audit is a skill published in the GitHub repository CurtisThe/three-pillars-plugin (4 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 34 tokens to every session and 4,717 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
