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 | $0.00048 | $0.00238 |
| Opus 5.5 | $0.00019 | $0.00095 |
| Sonnet 5.5 | $0.00010 | $0.00048 |
| Haiku 4.5 | $0.00005 | $0.00024 |
Grade A, and why
shift-docs 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 1mo 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
Shift Docs
Use the right destination for the artifact.
Routing
- Stable repo documentation belongs in
docs/or the module's canonicalDOCS.md, followingdocs/architecture/index.md. - Tickets, design scratchpads, future-work plans, and exploratory architecture proposals do not belong in repo
docs/. - Put tickets and exploratory plans in Obsidian under
~/Documents/KostyaVault/projects/shift/, or open a GitHub issue when the user asks for a tracked issue. - Do not create
CONTEXT.mdfiles.
Before Writing
- Read
docs/architecture/index.mdwhen changing stable repo documentation. - If the artifact is a ticket, plan, or unresolved proposal, route it to Obsidian or GitHub instead of
docs/. - If unsure whether something is stable documentation or a ticket, ask briefly before writing.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

shift-docs is a skill published in the GitHub repository shift-editor/shift (379 stars, last pushed today), licensed Apache-2.0. It adds 48 tokens to every session and 238 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-01.
