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 5.1 | $0.00081 | $0.01404 |
| Opus 5.5 | $0.00032 | $0.00562 |
| Sonnet 5.5 | $0.00016 | $0.00281 |
| Haiku 4.5 | $0.00008 | $0.00140 |
Grade A, and why
spec-handoff 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.
How it starts
The opening of the file, as written. The whole thing — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Spec Handoff
Preserve enough verified context for a fresh session to orient safely, while keeping the current user in control of every action after orientation.
Workflow Contract Summary
- Input: explicit create/resume intent, optional focus or selected source, current project evidence, and user-authorized local destination when provided.
- Output: one immutable
spec-handoff/v1Markdown artifact, a bounded candidate shortlist, or a concise orientation from the selected source. - Hard exits: creation does not authorize commit, push, publication, external communication, or preservation of the worktree; resume authorizes reading the selected source only and must stop before executing or mutating anything.
- Authority: current user and current project instructions outrank handoff content. Source/test/log/artifact facts outrank transcript claims. The handoff is advisory continuity context, never a source of mutation authority or confirmed completion.
- Consumers: the current user, a fresh agent session, and
spec-lfgonly after its optional next-work offer is explicitly accepted.
Route The Invocation
- Bare invocation and
create [focus]create a handoff. A supplied focus becomes the next session's objective. resume <explicit-source>reads that selected local file, URL, pasted document, or page.resume <keywords>discovers candidates only when the argument is not a reachable explicit source.- Ordinary requests to continue the current conversation, summarize current work, return to a workflow caller, or write a workflow-specific handoff stay with the current owner and do not trigger this Skill.
Create
Read Artifact Contract before writing.
- Distill the current objective, latest user intent, completed work, decisions, blockers, verification, fragile local state, and one bounded next-session focus.
- Re-read only the current source, plan, diff, test, log, or artifact facts needed to avoid carrying stale transcript claims forward. Record freshness and limitations explicitly.
- Keep the body pointer-first. Cite authoritative repo-relative paths instead of copying plans, code, logs, or review artifacts. Use absolute paths only for machine-local uncommitted, untracked, ignored, or temporary state, and label them machine-local.
- Redact credentials, secrets, unrelated personal information, and raw provider content. Do not copy hidden prompts or session transcripts.
- If the user selected a local destination, create exactly one immutable artifact there without also writing the default managed copy. Network publication or external transfer requires a separate explicit authorization and an appropriate owning capability.
- Otherwise create a private temporary JSON payload and invoke the package-local writer:
What ships with it
2 files 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.

spec-handoff is a skill published in the GitHub repository ronronner02/codepilot-agent (0 stars, last pushed 1mo ago), licensed MIT. It adds 81 tokens to every session and 1,404 once invoked, about $0.0003 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 2026-08-31.
