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.

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 | $0.00069 | $0.00283 |
| Opus 5.5 | $0.00028 | $0.00113 |
| Sonnet 5.5 | $0.00014 | $0.00057 |
| Haiku 4.5 | $0.00007 | $0.00028 |
Grade A, and why
paperecho-update 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 2mo 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
PaperEcho Update
Use the deterministic updater; do not improvise file copying or Git transitions.
- For “有更新吗 / 是否最新版 / 能否安全更新”, run
node skills/paperecho-update/scripts/update.mjs --check --json. - For an explicit update request, run the same check first. Run
node skills/paperecho-update/scripts/update.mjs --apply --jsononly whensafeToApplyis true. - Add
--install-dir <path>when detection reports multiple candidates. Never choose one automatically. - Treat network, active-run, update-lock, managed-file conflict, unsupported contract/schema, and developer-checkout results as blockers. Do not modify the live installation.
- Never accept an alternate repository URL, follow
main, downgrade, install Git, kill PaperEcho, or expose configuration contents.
Read update-policy.md for the safety model and update-contract.json for the release-owned managed/persistent boundary.
What ships with it
4 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.
