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 | $0.00112 | $0.01690 |
| Opus 5.5 | $0.00045 | $0.00676 |
| Sonnet 5.5 | $0.00022 | $0.00338 |
| Haiku 4.5 | $0.00011 | $0.00169 |
Grade A, and why
secrets-manager 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.

Secrets Manager
Overview
This skill governs the full lifecycle of secrets: keeping them out of source code, storing them in the right backend, injecting them at runtime, rotating them on schedule, and remediating leaks fast and completely. A leaked credential is an active incident — assume it is compromised the moment it touches a public surface.

Workflow
-
Classify the request into one of four modes (see Decision Framework):
- PREVENT — keep new secrets out of code.
- STORE/INJECT — choose a backend and runtime delivery.
- ROTATE — establish rotation cadence and automation.
- REMEDIATE — a secret has already leaked.
-
If a secret may already be exposed, treat it as REMEDIATE first. Rotation/revocation precedes cleanup. Removing the secret from git does NOT un-leak it. Follow
references/leak-remediation.mdstep by step. -
Scan before you advise. Run
scripts/scan_secrets.pyover the repo (or recommendgitleaks/trufflehogfor git history). Never assume the codebase is clean. Report findings with file, line, and a redacted match — never echo full secret values into logs, chat, or commits. -
Pick a storage backend using the matrix in
references/storage-backends.md. Match to the runtime (local dev, CI, Kubernetes, serverless, VM) and the org's existing cloud. Prefer short-lived, dynamically-issued credentials and OIDC/workload identity over long-lived static keys wherever possible. -
Define injection. Secrets reach the process via environment variables, mounted files (tmpfs), or a fetch-at-startup SDK call — never baked into images, never committed. Use
templates/dotenv-template.mdfor local dev and document.envin.gitignore.
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.

secrets-manager is a skill published in the GitHub repository JayRHa/AgentSkills (12 stars, last pushed 2mo ago), licensed MIT. It adds 112 tokens to every session and 1,690 once invoked, about $0.0004 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 2026-08-31.

cost-optimizer
Trigger when the user asks to audit Claude Code costs, reduce token spend, says "my Claude bill is too high", "optimize my CLAUDE.md", "why is this project burning tokens", or "/cost-optimizer". Scans a project for the common Claude Code cost leaks and returns a prioritized fix list.
excalidraw-architecture
Trigger when the user asks for an architecture diagram, says "draw the system", "update the architecture diagram", "give me an excalidraw of this codebase", or "/excalidraw-architecture". Generates or updates an Excalidraw JSON file at docs/architecture.excalidraw by reading the codebase's key entry points.
model-cost-compare
Trigger when the user asks which model to use, wants to compare model costs, says "what's cheapest for this task", "should I use Opus or Sonnet", "can a smaller model handle this", or "/model-cost-compare". Estimates token cost across Opus 4.6, Sonnet 4.6, GLM-5.1, Minimax M2.7, and local Gemma 4, then recommends the…
openclaw-debugger
Trigger when an OpenClaw agent is broken, silent, crashing, stuck, not responding, returning empty output, or the user says "my agent is down", "agent not working", "/openclaw-debugger". Walks through the standard OpenClaw 2026.4 diagnosis checklist and prints a report.
git-commit-writer
Trigger when the user asks to write a commit message, generate a commit from staged changes, review a diff before committing, or says "/commit". Reads git diff --staged and produces an opinionated, convention-matching commit message.
