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 | $0.00018 | $0.00593 |
| Opus 5 | $0.00009 | $0.00296 |
| Sonnet 5 | $0.00004 | $0.00119 |
| Haiku 4.5 | $0.00002 | $0.00059 |
Grade B, and why
sync-skills 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 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.

How it starts
The opening of the file, as written. The whole thing — 71 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/sync-skills — pull updated infrastructure files from skills
Run this when the upstream agentic-skeleton skill has been updated and
you need to bring this repo's .claude/ infrastructure files in sync.
Covers hooks, rules, commands, and agents — not repo-specific content.
Source directories
Brownfield source (prefer this for retrofitted repos):
~/.claude/skills/agentic-skeleton/templates/brownfield/PR5-delegation-hooks/files/
Greenfield source (fallback for files not found above):
~/.claude/skills/agentic-skeleton/templates/greenfield/
What to sync
For every file under .claude/ in this repo, check whether a
matching file exists in the brownfield source (same relative path).
If yes: read the source and overwrite the local file.
If not in brownfield source: check the greenfield source.
If not in either source: leave the local file untouched.
Directories in scope: .claude/hooks/, .claude/rules/,
.claude/commands/, .claude/agents/.
What NOT to touch
.claude/settings.json— wires hooks and permissions; repo-specific, can't be safely overwritten. Update manually if needed.VIBE.yaml— repo policy, repo-specific.AGENTS.md— repo-specific..mcp.json— repo-specific.- Any file under
.claude/that has NO matching source file.
Procedure
-
Confirm the skill source exists:
ls ~/.claude/skills/agentic-skeleton/templates/brownfield/PR5-delegation-hooks/files/.claude/If missing, stop and tell the user to run
make sync-linksin the agent-skills repo. -
For each local file in
.claude/hooks/,.claude/rules/,.claude/commands/,.claude/agents/: find the corresponding source file in brownfield (falling back to greenfield), read it, and write the local copy. -
Show a summary of which files were updated and which were unchanged (diff at a glance — filenames only, not full diffs).
-
If any files changed, commit:
chore: sync .claude/ infrastructure from agentic-skeletonNo PR needed — this is a maintenance update, not a feature branch.
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.

sync-skills is a command published in the GitHub repository rex/mcp-rancher (1 stars, last pushed yesterday), licensed MIT. It adds 18 tokens to every session and 593 once invoked, about $0.0001 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 2026-08-31.
