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 | $0.00181 | $0.01231 |
| Opus 5 | $0.00090 | $0.00616 |
| Sonnet 5 | $0.00036 | $0.00246 |
| Haiku 4.5 | $0.00018 | $0.00123 |
Grade A, and why
tia.review 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 12d 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.
How it starts
The opening of the file, as written. The whole thing — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.
tia.review — audit an existing project vs the baseline (class R, read-only)
Audit a connected TIA project against the non-negotiable baseline (TIA
best-practices §0) and the naming/architecture rules (§4/§5/§8). It is a
read-only review: it enumerates the project model through the tia MCP read tools and
reports deviations — it never changes anything.
When to use
- "Review / audit / lint my TIA project", "is this following best practices", "code health".
- Before exporting (project-as-code) or before a delivery/handoff.
- After a scaffold, as an independent quality pass (complements
tia.verify, which is the compile/consistency ladder; this is the style/architecture audit).
Preconditions
- A project must be open/connected (
tia_status→hasProject:true). If not, this is a GATE: connecting istia.handoff/tia_connectterritory (G1 trust dialog) — ask the human, do not force it.
Inputs / tools (all read-only, class R)
tia_status,tia_project_info,tia_project_languages— project context.tia_plcs→ for each CLP:tia_plc_blocks(name, type, language, number,isConsistent,isKnowHowProtected),tia_plc_types(UDTs),tia_plc_tags(tables + tags, addresses),tia_plc_watchtables.tia_devices/tia_device_tree— hardware.tia_obj_get/tia_obj_items/tia_obj_services— to read attributes the typed endpoints don't expose (e.g. a block's optimized-access attribute, a tag's symbolic vs absolute binding).BASELINE.md(bundled) — the authoritative checklist: each rule's ID, what to read, the predicate, severity, and PLCopen naming prefixes.
Outputs
A findings report. For each deviation: rule (ID from BASELINE.md), severity
(error = breaks baseline, warning = style), location (CLP / block / tag / device),
observed, expected, and fix (the concrete change — but as a recommendation; this
skill does not apply it). End with a per-rule pass/fail summary and an overall posture.
What ships with it
1 file 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.

tia.review is a skill published in the GitHub repository renanlido/tia-harness (5 stars, last pushed 1mo ago), licensed MIT. It adds 181 tokens to every session and 1,231 once invoked, about $0.0009 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 2026-08-31.
