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 | $0.00042 | $0.02169 |
| Opus 5 | $0.00021 | $0.01085 |
| Sonnet 5 | $0.00008 | $0.00434 |
| Haiku 4.5 | $0.00004 | $0.00217 |
Grade B, and why
manage-skills-drift-triage 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.

Skill Hardlink Drift — Audit and Triage
manage-skills keeps skills in sync via hardlinks: one inode, many paths. Copies drift
apart anyway. This skill covers the two things the CLI does not do for you: auditing
across repos (check/sync only ever look at $PWD), and deciding what to do
once the content actually differs.
The rule for the easy case lives in skill manage-skills: byte-identical files on
different inodes get linked on sight, no permission needed. Everything below is for when
that rule does not apply.
How drift actually happens
- A hardlinked
SKILL.mdwas edited withEdit/Write. Both rewrite-and-replace → new inode for the edited path, old inode (and its stale content) stays behind on every other path. Linkcount on the edited file drops to 1. Skillmanage-skillshas the rule (cat > file) and the repair steps. - A project got a one-time copy instead of a link. Common when a skill set was
bootstrapped by copying files in, not by
manage-skills link. The copy never enters the sync loop — it just ages while the source keeps evolving. - A project is shadowed by priority order.
discover_skillsdedups by name and the first source in the file wins. If project B provides its ownfoobut project A is listed earlier and also provides afoo, B's copy never wins — and never gets refreshed either, becausesynconly relinks against the winning source.manage-skills locationsmarks these with*, so this one is now visible without an audit. - Someone changed the skill on purpose. A project needed something different, edited
its copy and committed it. This looks identical to the accident above —
[~], linkcount 1 — butsyncno longer overwrites it: since v0.8, a copy whose content differs is reported asdivergedand kept, and onlysync --forcerelinks it. The commit in that project's history is what tells a deliberate change from an accident, so read it before reaching for--force; the question is whether the change belongs upstream, not how to undo it. - A directory that should be a source isn't registered at all (
~/.claude/skillsis the usual one). Project-local copies of those skills have no sync path back to the canonical copy, so nothing ever compares them.
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.

manage-skills-drift-triage is a skill published in the GitHub repository Getty/manage-skills (12 stars, last pushed 17d ago), licensed MIT. It adds 42 tokens to every session and 2,169 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 1 finding (enumerates other installed skills). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
