📦 PR: feat(bitflow-user-earnings-primitive): add read-only Bitflow user-earnings reporter (answers #609)#610
Conversation
…nings reporter
Read-only primitive answering "how much has user X earned on Bitflow?" by wrapping
the 5 BFF App API /earnings/* endpoints under /api/app/v1/users/{user_address}/.
Default-and-drill-down CLI: `run --address SP...` returns headline P&L cards at
period=life (the official displayed P&L); --history / --events / --pool / --rollups
flags drill into the underlying layers.
Pass-through, no derivation. Bitflow's backend computes APR/APY; this skill is a
courier with annotations. Pool-type-aware APR/APY semantics quoted verbatim from
the Bitflow frontend tooltips (HODLMM active-bin formula vs Classic historic-average
organic-APY formula) — embedded in SKILL.md, AGENT.md, and every response that
carries APR/APY fields via _dataQuality.apr_semantics.
Skill performs decimal-string monetary normalization (only deviation from pure
pass-through — BFF itself is inconsistent: USD typed as number in /earnings but
as decimal-string in /events + /pnl*), client-side Stacks address validation
(server doesn't validate), 404→cards:[] mapping for /pnl/{pool_id} no-position
case, and a _dataQuality envelope flagging 9 known upstream issues (empty rollups,
null timestamps, broken pagination, schema inconsistencies, etc.).
Zero credentials, zero wallet state, zero broadcast. Caller provides --address
always. Skill is a leaf in the dependency tree.

(404 mapped to success with cards:[]), --events --page 2 (pagination_broken

TL;DR: Solid primitive. CI green, frontmatter clean. Three suggestions and one nit, nothing blocking.
What I checked

- CI: all checks pass (
validatejob: ✅) - Security surface: read-only, no credentials, no wallet mutation, no broadcasting — confirmed by code inspection
What's strong
_dataQuality envelope is the standout design decision. Surfacing 9 known upstream issues (null timestamps, broken pagination, empty rollups, 404 conflation) as first-class structured fields — rather than silently swallowing them or pretending the data is clean — is exactly what agent callers need. This is the right pattern for wrapping imperfect upstream APIs.
Address validation before HTTP — the BFF server returns 200 + empty payload for malformed addresses, which would silently mislead. The client-side regex check (/^S[PM][0-9A-HJ-NP-Z]{39}$/) catches this before wasting a round trip. Correct and necessary.
APR/APY semantics embedded verbatim from Bitflow frontend tooltips, with the pool-type distinction (HODLMM dlmm_* vs Classic xyk/stableswapv2). These are easy for a downstream agent to conflate; embedding them in every response's _dataQuality.apr_semantics is the right call.
Error code enum (INVALID_ADDRESS_FORMAT, UPSTREAM_RATE_LIMITED, etc.) enables agent flow control without string matching. Good interface contract.
pnl_pool 404 → {status:success, cards:[]} mapping cleanly handles BFF's conflation of "no position" and "pool doesn't exist" — documents the limitation rather than propagating the ambiguity.
Suggestions
[suggestion] Multiple drill-down flags: undefined precedence
// In run action:
let kind: EndpointKind = "pnl";
if (opts.pool) kind = "pnl_pool";
if (opts.history) kind = "history";
if (opts.events) kind = "events";
if (opts.rollups) kind = "rollups";If a caller passes --pool dlmm_1 --history, history silently wins (last assignment). If they pass --events --rollups, rollups wins. Neither is documented. The fix is a mutual-exclusion check before the kind assignment:
const drillDownFlags = [opts.pool && "--pool", opts.history && "--history", opts.events && "--events", opts.rollups && "--rollups"].filter(Boolean);
if (drillDownFlags.length > 1) {
// fail with INVALID_FLAG_VALUE: "Flags are mutually exclusive: pass at most one of --pool, --history, --events, --rollups"
}This makes the error message the contract instead of leaving callers to discover the behavior by accident.
[suggestion] --format table is unimplemented
} else {
// table — minimal; full JSON for inspection
console.log(JSON.stringify(env, null, 2));
}table silently falls through to JSON. Either implement a minimal tabular view (earnings by pool, one row each), or remove table from the --format option and the CLI help string. Advertising an option that delivers something else will confuse agents parsing the help text.
Nits
[nit] timescale in QueryFlags is dead code
interface QueryFlags {
// ...
timescale?: string; // never set in the run action
}The /earnings endpoint accepts a timescale query param per the OpenAPI spec, but no --timescale flag exists in the CLI, so q.timescale is always undefined. Either expose it or remove it from the interface to keep the type honest.
[question] pool_tokens: {} on 404 path
In the pnl_pool 404 branch, the payload sets pool_tokens: {}. The success path sets pool_tokens: normalizedBody.poolTokens. Minor shape inconsistency — probably intentional since there's no upstream body to extract from on a 404, but worth confirming the caller contract is documented (it is in _dataQuality.no_position_in_pool).
Security
Read-only confirmed by code inspection. No credentials, no wallet state, no broadcasts. fetchWithTimeout wraps AbortController correctly. User-Agent header set. Stacks address validation is the right gate given BFF's silent 200s on malformed input. No issues.
Approving. The suggestions are worth addressing before a downstream agent ships a loop against --events --rollups, but they don't block the merge.

Review at HEAD 05e3cf45
Read-only Bitflow earnings reporter. Clean safety profile — zero broadcast, zero credentials, zero wallet state, address-stateless. This sidesteps the entire fund-safety surface that gated the write skills. One real bug to fix before merge; the rest is solid.
✅ What's done well
read-onlytag present:tags: "defi, read-only, l2, infrastructure"— correctly signals the safety profile- Exit codes are sane:
emit()returns0(success) /2(error). The rollups-empty-upstream case returnsstatus: success/ exit 0 with the_dataQuality.rollups_empty_upstreamflag rather than a hard failure — degraded-upstream is correctly distinguished from skill-failure. Good call not exiting nonzero on a successful courier of degraded data. _dataQualityenvelope implemented with all 9 known upstream issues, each flagged per-response rather than silently worked around. This is the skill's best feature — turns hidden upstream breakage into a documented contract.- APR/APY semantics verbatim from Bitflow tooltips, embedded in every response's
_dataQuality.apr_semantics— correctly never conflates the two pool-type definitions of the same JSON key. - 404 → success normalization on
/pnl/{pool_id}(no-position-in-pool) is the right semantic: "what did user X earn in pool Y where they have no position" = "zero," a successful zero-data result, not an exception. - Decimal-string monetary normalization across all USD/BTC/token fields — the consistency layer where upstream is inconsistent.
- CI green, validator passes, frontmatter compliant (
requires: "",author+author-agentpresent,user-invocable: "true"appropriate for a safe read-only skill).
🔴 Fix before merge — address validation rejects valid 40-char addresses
const STACKS_ADDRESS_REGEX = /^S[PM][0-9A-HJ-NP-Z]{39}$/;
if (addr.length !== 41) { /* INVALID_ADDRESS_FORMAT */ }This hard-requires exactly 41 characters. But Stacks c32check addresses are 40 or 41 chars — when the underlying hash160 has leading zero bytes, c32 encoding strips them and the resulting address is 40 chars. A legitimate 40-char SP… address gets rejected with INVALID_ADDRESS_FORMAT before any HTTP call.
This undercuts the skill's headline value-add: issue #5 in the _dataQuality table is "server doesn't validate addresses, so we do." But the validation is stricter than the chain itself — it refuses addresses the network considers valid. A user with a 40-char address can't query their earnings at all.
Fix options:
- Preferred: use
@stacks/transactionsvalidateStacksAddress()for real c32 checksum validation (catches typos the regex can't, e.g., a transposed char that's still in-charset). Adds one dep to an otherwise HTTP-only skill, but it's the correct validator. - Pragmatic (keeps it dependency-free): relax to
/^S[PM][0-9A-HJ-NP-Z]{37,39}$/and drop the strictaddr.length !== 41gate. Accepts the real 40-41 char range; still rejects obvious garbage.
Either way, add a 40-char SP… address to the smoke fixtures to confirm it's accepted.
🟡 Minor — exit codes collapsed vs PRD spec
PRD #609 §"Exit codes" specified exit 1 (caller error: bad address/flag) vs exit 2 (upstream error: BFF unreachable/5xx). The implementation returns 2 for both (status === "error" → 2).
Not a real problem — the JSON error_code + retryable fields let an agent distinguish caller-error from upstream-error programmatically, so only a shell branching purely on exit code loses the signal. But it's a deviation from the PRD's own contract. Either restore the 1-vs-2 split (map INVALID_ADDRESS_FORMAT/INVALID_PERIOD_TYPE → 1, upstream codes → 2) or update the PRD to match the simpler 0/2 scheme. One-line either direction.
Note on HODLMM declaration
The PR declares HODLMM integration "Yes" (registry-tagging rationale: the skill reads the BFF earnings surface that powers Bitflow's HODLMM dashboard, and all 9 live pools are dlmm_*). This differs from the #604 swap-venue precedent, but per maintainer ruling this is accepted for registry-tagging purposes on a read primitive. Noting it here for the record; not a blocker.
Verdict
COMMENTED. Genuinely strong read-only primitive — fills a real gap (no upstream skill exposes Bitflow user-earnings reads) with honest upstream-issue disclosure. One fix before merge: the address validation 40-char rejection (real bug, blocks legitimate users). Exit-code split is a nice-to-fix nit. Once the address validation accepts the valid 40-41 char range, I'll approve.
