What it does

Verify is an agent skill from mag123c/toktrack. Self-healing verification loop (test → clippy → fmt)

Its SKILL.md is about 680 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Ultra-fast token & cost tracker for LLM Token Usage (e.g. Claude Code). The licence is MIT.

Example prompts

“/verify”

What it can do on your machine

Read from SKILL.md and the folder at commit 75a86fa. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- cargo
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Verify loads about 676 tokens when it runs. Until then it costs about 15 tokens; SKILL.md has 299 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~15
When it runs · the whole SKILL.md, loaded when a task matches: ~676

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Verification Honesty (MUST — PASS gate)

Verification trustworthiness lies not in "what passed" but in "what was actually executed and passed". Enforced before any PASS verdict.

Skip ≠ Pass

Tests marked ignored / #[ignore] are unverified → do not count as green.
Tests skipped due to environment (missing external service, platform constraints, etc.) are a BLOCKER. If unfixable, escalate to user as "verification incomplete + reason" rather than PASS.

Do not cite unrun tests as verification evidence

"Confirmed via test X" is only valid when that test actually ran and passed in this execution.
Do not use a merely written test as evidence of "confirmed" (false-green = false reassurance).

Coverage honesty (mock ≠ real)

Mock-based unit tests verify only the logic inside the mock boundary. Behaviors invisible to mocks — file I/O, concurrency, simd-json real parsing — are confirmed only by integration verification.
If a path is covered only by mocks, report it as "mock coverage only — integration unconfirmed" rather than "verified".

Acceptance/DoD cross-check (carry PLAN gates)

Read the PLAN Acceptance/DoD and any [unverified-gate] passed from implement; cross-check whether each item actually ran and passed in this execution.
If unrunnable (prod smoke / external service / CI-only environment) → no green-wash. Tag as [unverified-gate: delegated, owner/due/probe] and carry to wrap Plan Reconciliation (../wrap/references/reconciliation.md).

Report format

✅ Actually executed and passed
⛔ Skipped/environment-blocked + reason (unresolved = BLOCKER, not PASS)
⚠️ Mock coverage only, integration unconfirmed
⏳ Delegated to wrap due to unverifiable Acceptance item

Self-Healing

Fail → analyze error → fix code → retry
Same error 3 times → notify user

Rules

Required before commit
Order: test → clippy → fmt
All must pass to proceed

Next Step

Only when the Verification Honesty gate passes (actual execution passed, no unresolved BLOCKERs) → call /review immediately. Do not ask "should I review?".

If there are unresolved BLOCKERs, do not proceed to /review — report "verification incomplete + reason + required environment actions" to the user.

Can I use Verify in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add mag123c/toktrack --skill verify -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/verify, .gemini/skills/verify, .github/skills/verify and .opencode/skills/verify in your project.

What does Verify need to run?

Going by SKILL.md and its folder, Verify needs the command-line tools its instructions call (cargo).

Does Verify access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

What licence does Verify use?

Verify is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Verify use?

About 676 tokens (SKILL.md is roughly 2.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Verify?

Skills that share tags, products or a category with Verify: Clippy (sundial-org/awesome-openclaw-skills, 663 stars), Run Clippy (r3bl-org/r3bl-open-core, 485 stars), Convex Self Heal (openclaw/clawhub, 9.5k stars) and Heal PR (razorpay/blade, 656 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
