Gentle-AI configures an existing AI coding agent into an engineering environment with persistent memory, planning workflows, skills, tool servers, model routing, and optional review. Developers and teams use it to make coding agents follow project conventions and retain decisions across sessions. The catalogue entries are its skills, commands, agents, and instruction.
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 | $0.00026 | $0.00487 |
| Opus 5 | $0.00013 | $0.00244 |
| Sonnet 5 | $0.00005 | $0.00097 |
| Haiku 4.5 | $0.00003 | $0.00049 |
Grade A, and why
go-testing 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 5d 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
Activation Contract
Load this skill when writing or reviewing Go tests, adding coverage, testing Bubbletea/TUI flows, using teatest, or updating golden files.
Hard Rules
- Prefer table-driven tests for multiple cases; use
t.Run(tt.name, ...). - Test behavior and state transitions, not implementation trivia.
- Use
t.TempDir()for filesystem tests; never rely on a real home directory. - Keep integration tests skippable with
testing.Short()when they run external commands or slow flows. - For Bubbletea, test
Model.Update()directly for state changes; useteatestonly for interactive flows. - Golden files must be deterministic; update only through the repo's
-updatepath and rerun tests without-update. - Use small mocks/interfaces around system or command execution boundaries.
Decision Gates
| Target | Test pattern |
|---|---|
| Pure function or parser | Table-driven unit test. |
| Error behavior | Explicit success and failure cases. |
| File operations | t.TempDir() plus focused assertions. |
| TUI state transition | Direct Model.Update() call with tea.Msg. |
| Full TUI interaction | teatest.NewTestModel(). |
| Rendered output | Golden file test. |
| Real external command | Integration test; skip in -short. |
Execution Steps
- Identify behavior under test and the smallest public boundary that proves it.
- Choose the test pattern from the decision gate.
- Name cases by scenario, not input mechanics.
- Assert outputs, errors, state, and side effects explicitly.
- Run the narrow package test first, then the relevant broader suite.
- For golden updates: run with
-update, inspect diff, then rerun without-update.
Output Contract
Report test files changed, scenarios covered, commands executed, golden files updated, and any skipped integration scope.
References
- references/examples.md — compact table-driven, Bubbletea, teatest, golden, and command examples.
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.

go-testing is a skill published in the GitHub repository Gentleman-Programming/gentle-ai (6,255 stars, last pushed today), licensed MIT. It adds 26 tokens to every session and 487 once invoked, about $0.0001 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.
