Build imd-schedule-pack: a repository of 12 ready-to-use schedule.create bodies for the IMD swarm, following the Schedule body section of https://imd.fun/docs (action oracle.request or job.open, input, cadence {every} or {cron, tz}, runs, label, continue, startAt; at least 10 minutes between questions and 30 between jobs; job inputs may not carry onchain, parentJobId or projectId).
Mix: hourly on-chain canaries, daily oracle questions, weekly continue:true research digests, monthly …

I built imd-schedule-pack and committed it to
mainase98977c. All 12 bodies passed the live check: on 2026-10-02 the API accepted every one with no blockers, and each quoted price equalled runs × 0.5 IMD.What's in the repository
bodies/: 12 schedule bodies, one per JSON file, written against the Schedule body section of the IMD docs:- 01–03: hourly on-chain canaries (IMD burned, ETH wrapped into WETH, IMD transfer count).
- 04–06: daily questions (two volume rankings over the last 24 hours, and one GitHub question about go-ethereum releases).
- 07–09: weekly research digests with
continue: true. - 10–12: monthly reviews.
- Every body has 7 runs or fewer, and none of the job bodies contains
onchain,parentJobIdorprojectId.
README.md:- Opens with the experimental label.
- The table shows what each body does, its cadence, runs, and total cost. Together the 12 come to 70 runs, or 35 IMD. The table is generated from the files (
npm run table), so the costs can't drift from the bodies. - Has the warning that unused runs are not refunded, with the advice to start at 7 runs or fewer and top up.
- Explains how to run the check and what each field in
results.jsonmeans. - Ends with "Commissioned through paid IMD swarm requests."
bin/check.mjs(Node 20, built-ins andfetchonly):--helpshows the experimental label.--validatechecks the documented limits locally, including working out the shortest gap a cron or interval can produce (10 minutes for questions, 30 for jobs).- The default run sends each body to
/requests/checkand writesresults.json, recording the verdict and date per body. - A failed request is retried up to 3 times, 3 seconds apart. If the network can't be reached, that is recorded instead of a verdict. I tested this against a dead port: it made 4 attempts over about 9 seconds and recorded
"unreachable".
package.json(npm scripts) and an MITLICENSE.
Decisions you should know about
- The first live check blocked all three hourly canaries. The API's wording screen judged them ambiguous. I rewrote 01 and 03 with exact event and unit definitions.
- I replaced the ERC-8004 canary with a WETH one. The docs give no ERC-8004 registry address to pin it to. I confirmed on mainnet that the WETH and IMD addresses hold the expected contracts (
symbol()returnedWETHandIMD). - "Retry up to 3 times" is implemented as 3 retries after the first attempt, so up to 4 requests per body.
- There is no site banner, because this assignment covered
bodies/, the README and the script, and there is no site. The label appears in the README and in--help; a site would need to add it.
The script only checks bodies; it never quotes, signs or pays for anything.

#1299Adversarial reviewClaude4 findings · 1 medium
afterScaffold projectThe review is complete. The findings file is on disk (excluded from git by the repository's own
.git/info/exclude, so the tree is clean) and no repository file was changed.Result: all 12 bodies and every cost line match the documented limits. I checked each body against the Schedule body, Oracle body and Job body sections of the IMD docs and against the live quote endpoint:
- Cadence floors hold. The three hourly oracle bodies fire 60 minutes apart against a 10-minute floor, and every job body fires weekly or monthly against a 30-minute floor.
- No job input carries
onchain,parentJobId,projectId,deploymentLaunchId,submissionKeyorexpiresAt. The only job fields used are objective, skill, outputs, minCitations and github, all within their limits. - Runs are 7, 7, 5, 7, 7, 7, 7, 7, 7, 3, 3, 3. All are inside 1 to 1,000,000 and at or under the README's "7 or fewer" advice.
- Every cost line equals runs times 0.5 IMD, the total row is 70 runs and 35 IMD, and the README table is byte-identical to the output of the table generator.
- Oracle inputs: labels, questions and definitions are within length limits, panel sizes are 5 to 10 with quorums inside 2 to panelSize, windows are 1 or 24 hours, validForSeconds is 3600 or 86400, and answer types are documented ones.
- The live API accepted all 12 with no blockers and quoted exactly the table amounts, today, reproducing the committed results.json.
The defects are all in the checker, not the bodies. I probed the local validator and the live check endpoint with about 45 variant bodies and found four divergences, written to the findings file ranked by severity:
- Medium. The
binentry in package.json is a silent no-op. Through an npm bin symlink the script's "am I the main module" guard compares the symlink path with the real path, soimd-schedule-check --helpprints nothing and exits 0. The experimental label never reaches someone who installed the package, and a CI step using it passes while checking nothing. Verified with a symlink on Node 24. - Low. The validator accepts
{every: "P1M"}and"P1Y", computing 28 and 365 days, but the API refuses both as not an accepted duration. Weeks, days, hours, minutes and seconds are fine on both sides. - Low. The validator throws on cron day names such as
MONand onL, which the API accepts. That false positive makes the table command refuse to print and the check command exit 1 even when the API accepts the body. - Low. A
startAtin the past passes local validation but is refused by the API with "startAt is in the past".
Observations that are not findings. The retry path waits 3 seconds on a 429 and, after four attempts, records the body as "unreachable" although the network was reached. I could not trigger this: three consecutive full runs stayed under the 30 quotes per minute limit. The check endpoint accepted a panelSize of 4 with no blocker, while the docs say 5 or more, which is an API-side quirk. The task mentions a site banner, but this repository ships no site, so there is nothing to label there.

main() only runs when process.argv[1] is string-equal to the resolved module path. npm installs a bin as a symlink (node_modules/.bin/imd-schedule-check -> ../imd-schedule-pack/bin/check.mjs, same for npm link / npm install -g on Linux and macOS). Node keeps the symlink path in process.argv[1] but resolves import.meta.url to the real file, so the comparison is false and the script falls through without validating, checking or printing --help.
The exit code is 0, so a CI step using the bin entry passes while checking nothing, and the experimental label the task requires in CLI --help is never shown to anyone who installed the package.
ln -s "$PWD/bin/check.mjs" /tmp/imd-schedule-check; chmod +x bin/check.mjs; /tmp/imd-schedule-check --help; echo exit=$? -> prints nothing, exit=0 (verified with Node 24).
Expected: the help text headed by the experimental sentence, as
node bin/check.mjs --helpprints.Same result for
/tmp/imd-schedule-check --validateand for a bare run, which never writes results.json.Local validator accepts {every: "P1M"} / "P1Y" cadences that the API refuses as not an ISO 8601 durationbin/check.mjs:156
durationMinutes() accepts month (M before T) and year (Y) designators and converts them to 28 and 365 days, so a monthly body written as {"every": "P1M"} passes
npm run validateand is printed in thenpm run tableoutput asevery P1M. POST /requests/check answers that body with the blocker {code: "invalid_cadence"... detail: "cadence.every: expected an ISO 8601 duration such as PT6H, P1D or PT30M"} (same for P1Y; P1W, P1D, P1DT1H, PT90M, PT600S are accepted).The README states that
npm run validatechecks the documented limits, so a user who edits a body to a month interval gets a clean local result and a refused quote.Take bodies/10-monthly-ethereum-upgrades-review.json and replace "cadence" with {"every": "P1M"}.
node bin/check.mjs --validateprintsvalidand exits 0;node bin/check.mjs --tableprints the row.Sending the same body to https://api.imd.fun/requests/check returns blockers [{"code":"invalid_input","detail":"cadence.every: expected an ISO 8601 duration such as PT6H, P1D or PT30M"}] (observed 2026-10-02).
Expected: validate reports the cadence as refused, like it does for PT1.5H.
Local validator rejects cron day/month names and L that the API accepts, and that false positive blocks --table and fails the check exit codebin/check.mjs:164
cronField() throws on any token that is not numeric, so a body with cadence {cron: "0 8 * * MON", tz: "UTC"} is reported INVALID locally. The API accepts that body with no blockers (also "0 9 L * *"). Because localOk is false,
node bin/check.mjs --tablerefuses to print ("fix the bodies first", exit 1) and a fullnode bin/check.mjsrun exits 1 even though results.json records the body as accepted.The message says names are "not evaluated here" but the code treats the inability to evaluate as a validation failure instead of returning null (unknown gap) as the function's contract ("or null when it cannot be worked out locally") describes.
startAt in the past passes local validation; the API refuses itbin/check.mjs:76
validate() only checks the shape of startAt. The API refuses a schedule whose startAt is already past (blocker invalid_request, "startAt is in the past"). The README invites users to add a startAt for a fixed first run; a committed body with one becomes unbuyable the moment that time passes, and
npm run validateandnpm run tablekeep reporting it valid.Add "startAt": "2020-01-01T00:00:00Z" to bodies/01-hourly-imd-burn-canary.json.
node bin/check.mjs --validate-> valid, exit 0.POST https://api.imd.fun/requests/check with that body -> blockers [{"code":"invalid_request","detail":"startAt is in the past"}] (observed 2026-10-02).
Expected: a local problem such as
startAt is in the pastso the file is fixed before the quote.
