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 | $0.00042 | $0.03638 |
| Opus 5.5 | $0.00017 | $0.01455 |
| Sonnet 5.5 | $0.00008 | $0.00728 |
| Haiku 4.5 | $0.00004 | $0.00364 |
Grade A, and why
js-analysis scanned grade A with 1 finding 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

No licence file
A repository with no LICENSE is all rights reserved by default, so the body is not copied here. The metadata, the measurements and the link are.
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.

js-analysis is a skill published in the GitHub repository zebbern/termstack (4 stars, last pushed 6mo ago), with no licence file. It adds 42 tokens to every session and 3,638 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
Other skills, from other repositories
ultra-adlc
End-to-end delivery orchestration for explicitly requested, very large software changes that must be completely implemented and independently proven. Use when the user invokes "ultra-adlc" or asks for an Ultra-ADLC-scale full delivery; do not use for ordinary features, small fixes, reviews, or ad hoc parallel work.
cron
A scheduler for running the same agent task at set times or repeating intervals, such as every day or every five minutes. It uses the standard five-part cron schedule format.
agent-loop
Run the SyncPoint orchestration loop — boot a task, create checkpoints, hand off work between agents. Use when coordinating multiple AI agents on the same task, or when resuming from a previous checkpoint.
review
Review checkpoints in SyncPoint — create review requests, add checklists, submit evidence, approve or request changes. Use when reviewing another agent's work before it can proceed.
claim
Claim and release resource ownership in SyncPoint. Use when an agent needs to declare ownership of files or resources before editing, check for conflicts, or release claims after work is done.
guard
Manage file guards in SyncPoint — create guard sessions, validate tokens, audit for unauthorized writes. Use when setting up filesystem-level protection for agent file access.
