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 | $0.00086 | $0.01245 |
| Opus 5 | $0.00043 | $0.00622 |
| Sonnet 5 | $0.00017 | $0.00249 |
| Haiku 4.5 | $0.00009 | $0.00125 |
Grade A, and why
td-integration-test 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 3d 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 — 107 lines — stays where its author put it; the contents beside it link to each section on GitHub.
td-sync Admin API Integration Tests
Write integration tests in internal/api/admin_integration_test.go using the harness in internal/api/testharness_test.go. Tests run against a real HTTP server on a random port with isolated temp databases.
Quick Start Pattern
func TestIntegration_DescriptiveName(t *testing.T) {
t.Parallel()
h := newTestHarness(t)
state := h.Build().
WithUser("[email protected]").
WithAdmin("[email protected]", "admin:read:server,sync").
WithProject("proj1", "[email protected]").
WithEvents("proj1", "[email protected]", 5).
Done()
token := state.AdminToken("[email protected]")
pid := state.ProjectID("proj1")
var resp adminEventsResponse
h.DoJSON("GET", fmt.Sprintf("/v1/admin/projects/%s/events", pid), token, nil, &resp)
if len(resp.Data) != 5 {
t.Fatalf("expected 5 events, got %d", len(resp.Data))
}
}
Harness API
See references/harness-api.md for the complete API reference with all method signatures and detailed usage notes.
Core
newTestHarness(t, ...func(*Config)) *TestHarness-- real HTTP server, isolated DB, auto-cleanuph.Do(method, path, token, body) *http.Response-- real HTTP request (caller closes body)h.DoJSON(method, path, token, body, &out) *http.Response-- request + JSON decode (fatals on 4xx/5xx)
State Builder
h.Build().
WithUser(email). // sync-scoped key
WithAdmin(email, scopes). // admin key with scopes
WithProject(name, ownerEmail). // via API (owner must exist)
WithMember(projectName, email, role). // "owner"/"writer"/"reader"
WithEvents(projectName, userEmail, count).// cycles issues/logs/comments
WithSnapshot(projectName). // triggers snapshot build
WithAuthEvents(count). // inserts directly to DB
WithRateLimitEvents(count). // inserts directly to DB
Done() // -> *TestState
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.

td-integration-test is a skill published in the GitHub repository marcus/td (244 stars, last pushed 6d ago), licensed MIT. It adds 86 tokens to every session and 1,245 once invoked, about $0.0004 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.

Pentest a web app or website end to end — black-box testing of a live URL, staging environment, or local dev server that finds and exploits real vulnerabilities (auth bypass, broken access control, IDOR, injection, XSS, SSRF, business logic) and proves each one with a working proof-of-concept instead of a signature…
