A diagnostic procedure for checking whether the project's work-measurement system is actually recording sessions and where its records are stored.

Use it when a measurement file is missing, a figure is questioned, or you need to verify the recorder's status.

It separates configured measurement from proof that a record was really written, so missing or misleading figures can be investigated.

02-check — Skill for Claude Code by ai-driven-dev

Install

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.

Any agent

npx skills add ai-driven-dev/framework --skill 02-check

Clone the repo

git clone --depth 1 https://github.com/ai-driven-dev/framework

Made for: Claude Code.

Or install aidd-telemetry, the plugin that ships this one along with the rest of its 3 skills.

Per session 91 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

When invoked 423 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00091	$0.00423
Opus 5	$0.00046	$0.00211
Sonnet 5	$0.00018	$0.00085
Haiku 4.5	$0.00009	$0.00042

Measured 2d ago against content hash fbd2bf01b028, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-11, from the pricing page.

Security

Grade A, and why

02-check 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

Check

flowchart LR
  ask([project]) --> locate --> diagnose
  diagnose --> inplace([what is in place])
  inplace -.->|"measurement off"| stopped([stopped])
  inplace -.->|"not a git repository"| stopped
  inplace --> answer([four claims])

Actions

Run the flow above. Read only the next action file.

Action	Does
locate	confirm the CLI
diagnose	run it, and present every line it printed

Transversal rules

Checking that a hook fired is not the same as checking that a file exists. A run file with only session_start is not evidence of anything closed.
Run only aidd telemetry check. Never a script, and never a command belonging to another skill.
Present every printed line. A line this skill leaves out is a claim the user cannot check.
What is in place is printed first and is never a claim — it appears whether or not measurement is on, and names the file behind every fact so the user can go and change it.
ok, FAIL and -- are three different answers. -- means there was nothing to evaluate, not that the chain is healthy.
A declaration that the recorder is set up is not proof it fired. Relay it as what it is — a fact about configuration, never a promise about behaviour.
The aidd command cannot be found: say so and check nothing.

Files

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.

Changes

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.

02-check is a skill published in the GitHub repository ai-driven-dev/framework (460 stars, last pushed yesterday), licensed MIT. It adds 91 tokens to every session and 423 once invoked, about $0.0005 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 2026-09-09.
