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 | $0.00061 | $0.01391 |
| Opus 5 | $0.00030 | $0.00696 |
| Sonnet 5 | $0.00012 | $0.00278 |
| Haiku 4.5 | $0.00006 | $0.00139 |
Grade A, and why
codoop-ux-walkthrough 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 — 147 lines — stays where its author put it; the contents beside it link to each section on GitHub.
User Experience Walkthrough
Run a qualitative, first-person walkthrough of a real product task. This skill produces hypotheses and improvement ideas for human review; it does not approve or reject a release, edit code, or create follow-up tickets.
When codoop_flow.toml is available, read output_language and use it for the
walkthrough conversation, persona prompt, and experience_report.md. "auto"
or a missing field follows the user's current language. An explicit request for
the current task overrides the config.
Read user_role too; a missing value means general. It changes only the live
conversation: use normal professional terms inside the user's field, and explain
cross-field topics in plain language. The user's current request for simpler or
more professional language overrides it. Do not apply this profile to the
persona prompt, report, code, ticket documents, or other generated files; those
remain precise and professional.
Core Rules
- Read
$SKILL/../../runtime/codoop-flow/agents/persona-walkthrough.mdand use it as the persona prompt without changing its contents. - Distinguish what was observed from what was inferred. This is a qualitative simulation, not user research or statistical evidence.
- Ground every finding in an actual screen, interaction, log, or explicitly stated limitation. Never invent product behavior or user feedback.
- Keep the persona independent. The product's stated user role, goal, and acceptance criteria constrain the task being tested; they do not force the persona's identity.
- Never change source code, tests, tickets, or scope as a result of this report. A human decides whether an idea becomes a later ticket.
Inputs
Gather the smallest useful context:
- Persona profile — use one supplied by the user, or propose a concrete profile and label it as an assumption. It may be a core, adjacent, or stress-test user, but must plausibly use the product.
- Task contract — when a ticket exists, read
module_prd.mdfor its user role, goal, scope, and acceptance criteria. Otherwise ask for the task the persona should accomplish and what success means. - Runnable evidence — use the live app, browser, simulator, screenshots, or test output available in the current environment. State what was and was not available.
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.

codoop-ux-walkthrough is a skill published in the GitHub repository Codoop/codoop-flow (5 stars, last pushed 8d ago), licensed MIT. It adds 61 tokens to every session and 1,391 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 2026-08-31.
