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 | $0.00122 | $0.03269 |
| Opus 5.5 | $0.00049 | $0.01308 |
| Sonnet 5.5 | $0.00024 | $0.00654 |
| Haiku 4.5 | $0.00012 | $0.00327 |
Grade F, and why
chunk-sidecar-setup scanned grade F with 4 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.
Harvests environment variableshighData exfiltration
Enumerating or grepping the environment for keys collects credentials unrelated to what the mod says it does.
- **Auth errors (401/403, "token invalid")** — run `chunk auth status`. If the CircleCI token is stale or missing, re-run `chunk auth login` ([Logging in](#logging-in)). Never dump env vars. Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
chunk validate --remote --cmd "curl -fLSs https://raw.githubusercontent.com/CircleCI-Public/circleci-cli/main/install.sh | sudo bash" Downloads and executes remote codehighSupply chain
curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.
chunk validate --remote --cmd "curl -fLSs https://raw.githubusercontent.com/CircleCI-Public/circleci-cli/main/install.sh | sudo bash" Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

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 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.

chunk-sidecar-setup is a skill published in the GitHub repository CircleCI-Public/skills (6 stars, last pushed 2d ago), with no licence file. It adds 122 tokens to every session and 3,269 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it F with 4 findings (harvests environment variables, asks for root, downloads and executes remote code). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-10.

Verification & Quality Assurance
Comprehensive truth scoring, code quality verification, and automatic rollback system with 0.95 accuracy threshold for ensuring high-quality agent outputs and codebase reliability.
quality-scan
Run a scoped, read-only quality scan and report exact-candidate evidence, failures and frozen debt. Use for an ad-hoc gate sweep or release preparation; a static scan is not full release acceptance.

Use when reviewing CI coverage, automated checks, or test strategy related to Implement end-to-end testing. Focus on whether the rule is continuously verified, not just documented.
