clari-local-dev-loopBuild and test a Clari integration locally with redacted fixtures and a deterministic job simulator.
Clari Local Dev Loop is an agent skill from jeremylongshore/tons-of-skills-marketplace. Build and test a Clari integration locally with redacted fixtures and a deterministic job simulator. Use when developing without spending quota or exposing customer data. Trigger with: "mock Clari locally", "build Clari fixtures", "test Clari offline".
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/official-docs.md`). Compatibility notes: Requires a local test runner, approved synthetic or irreversibly redacted fixtures, and a pinned provider contract snapshot.
It sits in Testing & QA. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.
6 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.
Pre-approves these tools, so the agent can use them without asking each time:
ReadGrepWriteEditFrom allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Links to these hosts (documentation or services it may open):
developer.clari.comapi-doc.copilot.clari.comFrom URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Requires a local test runner, approved synthetic or irreversibly redacted fixtures, and a pinned provider contract snapshot.
From compatibility in the SKILL.md frontmatter.
Clari Local Dev Loop loads about 1.1k tokens when it runs, and up to ~1.5k if it reads all its reference files. Until then it costs about 68 tokens; SKILL.md has 441 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

This skill also uses 1 other file; get the full folder from GitHub.Make offline development the default and live provider calls an explicit integration stage. Model the provider’s authentication headers, job transitions, pagination, error objects, and schema drift without storing secrets or production records.
List endpoints, headers, request fields, response fields, job states, and pagination semantics used by the integration.
Create minimal payloads that preserve shapes and identifiers while containing no real people, accounts, calls, forecasts, or deal values.
Make the test server move deterministically through queued, running, completed, aborted, rate-limited, and timed-out paths.
Run parser, schema, retry, pagination, idempotency, and redaction tests against the simulator with network access disabled.
Use a dedicated non-production identity and the smallest read-only request; skip it unless credentials and explicit integration-test approval are present.
When the provider contract changes, review the diff, update fixtures and assertions together, and retain the old failing fixture as migration evidence.
Offline tests must use obvious dummy values. A gated live test may read credentials from the approved secret manager at runtime, but must never serialize headers or provider payloads into test output.
Use Read and Grep to inspect configuration, provider contracts, fixtures, logs, schemas, and existing tests before proposing a change. Use Write or Edit only for the approved plan, implementation, test, or redacted receipt; do not issue, rotate, revoke, create, update, cancel, delete, export, ingest, or publish provider data without explicit operator approval.
Return the exact surface, environment, resource or job identifiers, contract fingerprint, evidence, unresolved risks, and final decision without exposing credentials or sensitive customer data.
A local export client receives synthetic SCHEDULED, STARTED, and DONE responses, then a 429 and an ABORTED job. CI proves bounded retry and redaction without consuming a Clari export.
| Failure | Response |
|---|---|
| Fixture contains real customer data | Quarantine and remove it, rotate any exposed credential, and replace it with generated values. |
| Mock diverges from the provider contract | Pin the current contract fingerprint and add a regression fixture for the observed delta. |
| Live smoke runs unexpectedly | Fail closed unless an explicit environment gate and non-production credential are both present. |

SKILL.md names no scripts, command-line tools or credentials: Clari Local Dev Loop is instructions for the agent only. Its frontmatter pre-approves these tools: Read, Grep, Write, Edit. Compatibility (from SKILL.md): Requires a local test runner, approved synthetic or irreversibly redacted fixtures, and a pinned provider contract snapshot..
SKILL.md names 2 domains. As links in the text: developer.clari.com and api-doc.copilot.clari.com. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Clari Local Dev Loop is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.1k tokens (SKILL.md is roughly 4.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 480 tokens, read only when the agent opens those files.
