verify

verify is a skill for Claude Code from chan4lk/specclaw. It costs 54 tokens per session (2,243 once invoked), scanned A, original, MIT.

A verification workflow for checking whether an implementation meets the acceptance criteria written in a project specification.

In plain words
What is it for?
Running the final checks after implementation tasks are complete and creating verify-report.md before a change is submitted for review.
Why use it?
It gathers test, lint, build, and optional end-to-end results in one report, while also checking the project's documented coding rules.

Skill for Claude Code

Written for Claude Code: $CLAUDE_PLUGIN_ROOT variable.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Token cost

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.

Security

Grade A, and why

verify 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 yesterday.

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.

How it starts

The opening of the file, as written. The whole thing — 140 lines — stays where its author put it; the contents beside it link to each section on GitHub.

specclaw verify

First, run specclaw-ensure-init .specclaw — idempotently creates .specclaw/ if it doesn't exist (silent if already initialized; auto-inits using the current directory's basename as the project name).

Validate that the implementation satisfies the spec.

Step 0 — Validate

specclaw-validate-change .specclaw <change> verify

If it fails (tasks not all complete), report and stop.

If .specclaw/context.md exists, read it before evaluating — the verifier must check that the implementation respects the project's coding rules, patterns, and constraints documented there, in addition to the spec's acceptance criteria.

Step 1 — Collect evidence

specclaw-verify collect .specclaw <change>

Gathers acceptance criteria from spec.md, current contents of changed files, and configured lint/build/test command results — run in that order — followed by the e2e tier when configured.

E2E tier (build.e2e_command + verify.e2e)

build.e2e_command is the slow tier (browser/e2e); build.test_command stays the fast tier. verify.e2e decides when the slow tier runs:

Policy Behaviour
last (default) Run e2e only after lint_command, build_command and test_command all pass. An unset fast-tier command is vacuously passing.
skip Never run e2e.
always Run e2e even when an earlier gate failed.

An absent verify.e2e means last; an unrecognised value warns on stderr and falls back to last.

When the e2e command does run, collect brackets it: it takes a browser slot (specclaw-browser-lock acquire), passes the command through specclaw-browser-lock wrap — which adds --workers=1 for Playwright, one sequential --project= invocation per verify.playwright.projects entry, and a MemoryMax=<verify.playwright.max_memory_mb>M scope when systemd-run is usable — runs the wrapped string, then releases the slot. The slot is released even when the command fails or the run is interrupted. When systemd-run is unusable, wrap warns and the command runs uncapped.

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.

verify is a skill published in the GitHub repository chan4lk/specclaw (12 stars, last pushed 2d ago), licensed MIT. It adds 54 tokens to every session and 2,243 once invoked, about $0.0003 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 2026-08-30.
