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 | $0.00037 | $0.00382 |
| Opus 5 | $0.00018 | $0.00191 |
| Sonnet 5 | $0.00007 | $0.00076 |
| Haiku 4.5 | $0.00004 | $0.00038 |
Grade A, and why
go-security 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 2d 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
Go Security
Security work walks attacker paths from trust boundary through principal, authority, asset, enforcement point, attacker action, and observable denial.
boundary -> principal -> enforcement -> action -> failure -> negative proof
For a delegated Decision or Review, or when the active artifact requires its
result interface, load the
shared specialist contract.
From every caller-controlled entrypoint to an asset or observable denial, build
AttackerPath{boundary, principal, asset, enforcement, action, failure, denial_proof} across route exposure, verified identity, objects reached,
outbound destinations, secrets, and caller-controlled work. Missing identity,
ambiguous tenant, or absent policy denies. Every accepted control needs focused
negative proof because an allow test also passes against a bypass.
Decide against existing owners: internal/infra/oidcjwt verifies tokens,
api/openapi/service.yaml declares default auth, internal/infra/httpclient
pins destinations, and internal/config separates secret inputs. Load the
reference selector for identity, exposure, interpreter
input, outbound destination, work amplification, or a secret sink.
For a Decision, disposition every reachable path with fail-closed behavior and negative proof. For Review, follow each path into the shared finding envelope; no findings still requires the focused deny proof. Load access control when the credential, permission, or revocation mechanism itself is open.
What ships with it
7 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.

go-security is a skill published in the GitHub repository Dankosik/go-service-template-rest (7 stars, last pushed yesterday), licensed MIT. It adds 37 tokens to every session and 382 once invoked, about $0.0002 per session on Opus 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.
