SkillSpector: 3 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
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 | $0.00106 | $0.01885 |
| Opus 5 | $0.00053 | $0.00942 |
| Sonnet 5 | $0.00021 | $0.00377 |
| Haiku 4.5 | $0.00011 | $0.00188 |
Grade A, and why
rebase 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 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.
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 — 151 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Rebase workflow
Move the branch onto its base, then establish that what came out is right.
A guard hook runs alongside. It refuses a rebase started by hand and a continue past a conflict git never checked. It also refuses a dropped commit that isn't empty, a bare stash pop, and a force push without a lease.
Preflight
!bash ${CLAUDE_SKILL_DIR}/scripts/preflight.sh
Step 0: the checklist
Track these steps with the session's task-list tools where it carries them. Newer harnesses leave those tools out by default, and a session without them works the list in order as written.
- Choose the base
- Settle the working tree
- Start the rebase
- Resolve whatever it stops on
- Verify the result
- Report
Preflight reporting a merge or cherry-pick in progress stops everything. Say what's in the way and hand back. A rebase already in progress is the other case, and that one resumes at step 4.
Step 1: choose the base
Preflight computed this under == rebase base ==. Take its recommendation.
- Local default branch carries everything the remote has, so rebase onto the local branch.
- Local default branch sits behind the remote, so rebase onto
origin/<default>and skip the stale local copy.
The commit skill's preflight makes the same decision, and both reach the same answer. Where the operator names a different base, use theirs and say why it differs.
Nothing to replay means nothing to do. Say so and stop.
Step 2: settle the working tree
--autostash handles a dirty tree, and start-rebase.sh passes it. It scopes the save to this rebase and never touches the shared stash stack, which is what makes it the sanctioned form here.
The stashed work sits outside the worktree while you resolve a conflict, so nothing you see there reflects it. It can also conflict on the way back once the replay finishes.
Where the work needs to survive a cancelled rebase as well, park it in a throwaway commit first:
git commit -am wip --no-verify
That's the one sanctioned --no-verify in this repository, and git reset --soft HEAD~1 afterwards removes it before anything reaches history.

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.
- 12d ago First seen · 151 lines · 106 tokens per session scan A 4dc106aa9991
rebase is a skill published in the GitHub repository tbhb/vale-ai-tells (93 stars, last pushed 2d ago), licensed MIT. It adds 106 tokens to every session and 1,885 once invoked, about $0.0005 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.

anti-slop
Remove AI slop from any voice-bearing prose — original posts, threads, articles, long-form, emails, docs, READMEs, marketing copy, bios, scripts. Use when drafting text meant to sound like a specific person or brand, when rewriting text that reads generic, corporate, or AI-generated, or when asked to humanize…

Audit a file or draft for AI slop and off-voice lines against the author's bound voice, report findings with in-voice swaps, then apply approved fixes. Use when the user says "kill slop", "/kill-slop [file]", "find the slop in this", "audit this for slop", or wants a deck, article, page, or draft cleaned to sound like…
