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 | $0.00021 | $0.00181 |
| Opus 5.5 | $0.00008 | $0.00072 |
| Sonnet 5.5 | $0.00004 | $0.00036 |
| Haiku 4.5 | $0.00002 | $0.00018 |
Grade A, and why
artifact-handoff-pack 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
Artifact Handoff Pack
Use this skill when ending a session, handing work to another agent, or preparing a review bundle.
Bundle Contents
- governing issue or task
- canonical artifact source
- generated review surface, if any
- manifest entry or freshness status, if generated review output exists
- changed files or relevant files
- verification evidence
- unresolved assumptions
- next executable action
Rules
- Prefer links and exact paths over prose summaries.
- Keep generated HTML optional and source-backed.
- Do not hand off an HTML artifact without its canonical source.
- Do not hide failed or skipped verification.

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.

artifact-handoff-pack is a skill published in the GitHub repository 45ck/skill-harness (15 stars, last pushed 4mo ago), licensed MIT. It adds 21 tokens to every session and 181 once invoked, about $0.0001 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 2026-08-30.

github-issue
Use when opening a GitHub issue, bug report, feature request, or discussion in any repository, including one the user has no local checkout of.
project
Use when reading or writing files under /Notes/Projects/, starting a new project, or archiving a finished one. Covers folder layout, the board file, supporting notes, and the project lifecycle across Future/, Projects/, and Archive/.
dispatch
Use when a session's job is to hand work out to other agents rather than do it — running a set of tasks across several projects or worktrees, a few at a time.
Telos
Dual-context skill: Personal TELOS reads and updates goals, beliefs, narratives, strategies, and more with timestamped backups; Project TELOS analyzes .md/.csv directories for dependency chains, bottlenecks, and alignment, generating reports, narrative points, or dashboards. USE WHEN Telos, life goals, projects…
triage
Triage issues through a state machine driven by triage roles. Use when user wants to create an issue, triage issues, review incoming bugs or feature requests, prepare issues for an AFK agent, or manage issue workflow.
to-prd
Turn the current conversation context into a PRD and publish it to the project issue tracker. Use when user wants to create a PRD from the current context.
