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 | $0.00008 | $0.00076 |
| Opus 5 | $0.00004 | $0.00038 |
| Sonnet 5 | $0.00002 | $0.00015 |
| Haiku 4.5 | $0.00001 | $0.00008 |
Grade A, and why
plan-migration 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.

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.

plan-migration is a command published in the GitHub repository sethdford/claude-skills (38 stars, last pushed 5mo ago), licensed MIT. It adds 8 tokens to every session and 76 once invoked, about $0.0000 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 2026-08-30.

verify
Run the full verification suite (build, type-check, tests, lint) via a fresh-context verification-runner subagent; reports evidence paths. Read-only by default; opt-in '--fix' runs a bounded auto-fix loop (max 2 cycles). Use before marking featurelist.json status as 'pass'.
index-project
(Re)build PROJECT-TOC.md — one-line index of every git-tracked source file, with git-commit freshness anchor.
cf-run
Run the context-firewall workflow: split inputs, invoke FileWorkers, aggregate into SubResult.v1.
