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 | $0.00018 | $0.00263 |
| Opus 5 | $0.00009 | $0.00131 |
| Sonnet 5 | $0.00004 | $0.00053 |
| Haiku 4.5 | $0.00002 | $0.00026 |
Grade A, and why
dead-code 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 3d 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 it actually says
Dead Code Analysis
- Find unused exports (TypeScript/JS):
npx ts-prune 2>/dev/null || npx unimported 2>/dev/null || echo "Running manual search"
- Manual search for likely dead code:
# Exported but never imported
grep -r "^export " src/ --include="*.ts" -l | head -20
# Functions defined but never called
grep -r "^function \|^const .* = (" src/ --include="*.ts" | head -30
-
For each candidate, verify by searching for all usages across the codebase.
-
Report categories:
- Safe to delete: confirmed zero usages
- Probably dead: only used in tests or commented-out code
- Keep: used dynamically or via reflection
-
For safe-to-delete items: ask confirmation, then remove.
Never delete code you're not certain about - mark uncertain items with // TODO: verify unused.
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.

dead-code is a skill published in the GitHub repository berkcangumusisik/claude-code-practices (10 stars, last pushed 4mo ago), licensed MIT. It adds 18 tokens to every session and 263 once invoked, about $0.0001 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.
