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 | $0.00044 | $0.00341 |
| Opus 5.5 | $0.00018 | $0.00136 |
| Sonnet 5.5 | $0.00009 | $0.00068 |
| Haiku 4.5 | $0.00004 | $0.00034 |
Grade A, and why
Verification Planner 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.
What it actually says
Verification Planner (v7.2.0)
You MUST use this skill when generating an implementation_plan.md. You are required to create a test_assertions.json file in the project root to guide the automated Verification Runner.
🚀 Workflow
- Plan: Alongside your MD plan, define assertions in
test_assertions.json. - Define Layers: Categorize tests into
data(schema),pipeline(files/APIs), oragent(logic). - Set Severity:
warn: Non-blocking logs.gate: Blocks progression on failure.abort: Stops the pipeline immediately (safety-critical).
🛠️ Assertion Types
sqlite_query: Validate DB state.http_status: Verify API health.file_exists/file_contains: Check filesystem.quickjs_eval: Sandbox JS logic for complex checks.
🧠 Claw-as-Validator
If PRISM_VERIFICATION_HARNESS_ENABLED=true, delegate your JSON suite to the local Claw agent for adversarial review before execution to catch missing coverage or false positives.

What ships with it
2 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.

Verification Planner is a skill published in the GitHub repository dcostenco/prism-coder (157 stars, last pushed today), licensed Apache-2.0. It adds 44 tokens to every session and 341 once invoked, about $0.0002 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 2026-08-30.

add-export
Add a new subpath export to the @cyanheads/mcp-ts-core package. Use when creating a new public API surface that consumers import from a dedicated subpath (e.g., @cyanheads/mcp-ts-core/newutil).
xmemo-memory
Persistent, user-owned memory for agents. Use the standalone runtime to remember, recall, search, preserve restart continuity, manage TODOs and expenses, inspect account overview, activity and stats diagnostics, read user Cloud Skills (read-only), configure agent instructions, check for updates or upgrade runtime, or…
typescript-lsp
Search TypeScript SYMBOLS (functions, types, classes) - NOT text. Use Glob to find files, Grep for text search, LSP for symbol search. Provides type-aware results that understand imports, exports, and relationships.
gitlab-review
Review a GitLab merge request, inspect changes and discussions, or prepare and post explicitly requested review feedback. Use for GitLab MRs and review follow-ups, not GitHub pull requests or automatic approval/merge.
gitlab-setup
Diagnose a GitLab MCP connection, selected account, token permissions, or missing tools in Codex or Claude Code. Use for GitLab setup and access problems, not unrelated application settings.
gitlab-ci
Investigate a failed GitLab pipeline or job, inspect bounded logs and explain an evidence-based fix. Use for GitLab CI failure diagnosis and related follow-ups, not perpetual monitoring or automatic job retries.
