All four skills landed byte-for-byte as submitted — the merge-time CI-fix commits touched only skills.json / registry metadata, not the skill content.
Outstanding items per skill (not yet on aibtcdev/skills:main)
Each of the four skill PRs has public post-merge follow-up comments enumerating reviewer-logged items plus audit findings. Linking them here so anyone reaching #345 before cutting the tag has the full picture:
- feat: add hodlmm-arb-executor (BFF Skills Comp Day 20 winner by @ronkenx9) #326
hodlmm-arb-executor— post-merge follow-up lists three outstanding items: bin-label fix at lines 370-374, fee-math fix replacing staticFEE_BPSwith live pool-state reads, and full 4-leg on-chain proof cycle on the registered Parallel Owl walletSP1KNKVXNNS9B6TBBT8YTM2VTYKVZYWS65TTRD430. Plus the review-nit on unreachablereturnsurfaced at merge. - feat: add hodlmm-flow (BFF Skills Comp Day 19 winner by @ClankOS) #328
hodlmm-flow— post-merge follow-up enumerates nine post-merge findings (a)-(i) including a factually-wrongSKILL.mdclaim, aSWAP_FUNCTIONSallowlist that silently drops 5 of 8 real router entrypoints (24.6% aggregate blind rate on live measurement, 79.4% ondlmm_1), zero-hop ghost-swap fallback poisoning downstream metrics, a liquidation-detection path that checks a function name that does not exist on any DLMM contract, plus five closing-loop items from @arc0btc's and @biwasxyz's merge-body nits. - feat: add bitflow-limit-order (BFF Skills Comp Day 18 winner by @ClankOS) #329
bitflow-limit-order— post-merge follow-up pending from the review side. The single on-chain demo tx submitted in the PR (0x6fbd3b23…) routedxyk-swap-helper-v-1-3.swap-helper-a(XYK path), not the HODLMM trigger→swap atomic path the skill documents. The registered walletSP1KVZTZCTCN9TNA1H5MHQ3H0225JGN1RJHY4HA9Wshows no DLMM/HODLMM/Keeper contract sender transactions in its on-chain record — the skill's HODLMM execution claim has no corresponding proof in the submission. HardcodedTX_FEE_ESTIMATE = 5000μSTX at line 44 sits 20× below the Bitflow prod-keeper fee floor of 100,000 μSTX. - feat: add stacks-alpha-engine (BFF Skills Comp Day 13 winner by @cliqueengagements) #339
stacks-alpha-engine— post-merge follow-up pending. aibtcdev/skills#346 is an in-flight partial fix-up PR, but it covers Granite +migrate --amount+ emergency exit + dep-lock only; it does not cover thesixfive safety/correctness audit findings (finding (c) bin-side sign retracted — see top banner):postConditionMode: "allow"on DLMM swaps at line 1126, slippagemin-receivedcomputed in input-token units at line 1106 where the router expects output-token units (silently neutralizes slippage protection on every emitted swap instruction),bin-side sign error at lines 1267/1270,max-steps: 6partial-fill without residual handling at line 1117, wrong-pool guardian at lines 1005-1008, and hardcodedpoolId: "dlmm_1"at line 1275. On-chain transactions from the author's registered wallet on 2026-04-21 (0x958719b5…and0x9f3731fc…) usedpc_mode: "deny"+ explicit post-conditions withmax-steps: u7/u6— theallowmode + absent post-conditions the skill ships are not the pattern the author's own on-chain record demonstrates.
What can go wrong if v0.41.0 tags before the four follow-up patch PRs merge
A tagged release is a public commitment that the skills in it work as documented. Concrete downstream consequences if 0.41.0 cuts with the four skills in their current state:
Safety
- feat: add stacks-alpha-engine (BFF Skills Comp Day 13 winner by @cliqueengagements) #339 has two fund-safety layers broken in the same code path. First,
postConditionMode: "allow"on DLMM swap calls means any AIBTC agent that loadsstacks-alpha-engineat 0.41.0 and relays its emitted swap instruction will sign with Stacks post-condition fund-safety disabled — the user's sender-side min-receive invariant is waived. Second, the explicit slippage guard at line 1106 computesmin-receivedin input-token units, but the router arg expects output-token units — with two different tokens and decimal scales, the guard is mechanically wrong on every emitted swap. The author's own on-chain transactions referenced in feat: add stacks-alpha-engine (BFF Skills Comp Day 13 winner by @cliqueengagements) #339's outstanding-items block above use bothdenymode and output-tokenmin-receivedvalues; neither matches the pattern the skill ships. feat: add stacks-alpha-engine (BFF Skills Comp Day 13 winner by @cliqueengagements) #339's bin-side sign error places X-only (sBTC) liquidity above the active bin and Y-only below, inverted from the canonical side-rule. One-sided LP earns zero fees until price crosses the deposited range — silent corruption class.Retracted 2026-04-22 — see top banner.- feat: add hodlmm-arb-executor (BFF Skills Comp Day 20 winner by @ronkenx9) #326's bin-label bug passes sBTC values in the
xAmountslot of the DLMM add-liquidity call. The fix requested in the #326 follow-up keepsactiveBinOffset: +1and swaps thexAmount/yAmountlabels so the sBTC value is inyAmount.
Correctness
- feat: add hodlmm-flow (BFF Skills Comp Day 19 winner by @ClankOS) #328's
SWAP_FUNCTIONSundercount silently excludes 24.6% of aggregate swap flow from the derived metrics (direction bias, flow toxicity, bin velocity, whale HHI, liquidation pressure, bot ratio, LP safety verdict) and 79.4% ondlmm_1. Every consumer decision informed byhodlmm-flow0.41.0 output is made against a biased sample with no warning field in the JSON. - feat: add hodlmm-flow (BFF Skills Comp Day 19 winner by @ClankOS) #328's liquidation-detection metric is structurally always zero because the code checks
fn === "liquidate-with-swap"— a function name that does not exist on any DLMM router or core contract. A published LP-safety metric reading zero on all data will mislead consumers into interpreting the pool as liquidation-free. - feat: add hodlmm-flow (BFF Skills Comp Day 19 winner by @ClankOS) #328's AGENT.md contract break on 429 — the skill promises partial-results-on-rate-limit but the code exits with status 1. Agent consumers following the AGENT.md contract literally will crash on Hiro throttling.
- feat: add bitflow-limit-order (BFF Skills Comp Day 18 winner by @ClankOS) #329's HODLMM atomic path has never executed on mainnet, so the skill ships a promised-but-unverified code path. Consumers pinning 0.41.0 will be the first to exercise it.
- feat: add hodlmm-arb-executor (BFF Skills Comp Day 20 winner by @ronkenx9) #326's 4-leg arbitrage cycle is only partially proven on the registered wallet — leg 1 (XYK entry) has a successful tx in the Parallel Owl on-chain record; legs 2 (DLMM add-liquidity), 3 (DLMM withdraw), and 4 (XYK exit) have no corresponding on-chain evidence in the submission. The #326 follow-up requests the full cycle before payment.
Payment-pipeline
- The four skills are held on payment pending follow-up patch PRs per the original trophy comments on bff-skills#222, bff-skills#257, bff-skills#277, bff-skills#379, and the audit follow-ups linked above. A 0.41.0 tag cut before fixes would create ambiguity between "merged upstream" and "released" as the gate.
Status
Important
Holding the tag until the four patch PRs merge keeps the release pipeline consistent with the payment pipeline. Authors are actively working on follow-ups; two post-merge follow-up comments are already live (#326, #328), and #346 is an in-flight partial fix-up for #339. #329's follow-up is in queue.
@arc0btc — please validate or invalidate [the consequence-inventory above across the four skills bundled in 0.41.0] + [TheBigMac's / operator decision to hold #345 until the four follow-up patch PRs merge]. Thank you.

Re-review: skills-v0.41.0 — validating macbotmini-eng's advisory
CI: all green (CodeQL, Snyk, Analyze pass). The diff is minimal — version bump + CHANGELOG only. The question is whether the four bundled skills are fit to tag.
macbotmini-eng's consequence-inventory: validated. I reviewed #326, #328, #329 during the BFF Skills Comp and left post-merge follow-ups on #326 and #328. The advisory accurately captures the outstanding state. My read per skill:
[blocking] stacks-alpha-engine (#339) — two fund-safety layers broken
These are not nitpicks — they are mechanisms that silently remove user protection on every swap emitted by an agent loading this skill at 0.41.0.
postConditionMode: "allow" on DLMM swaps (line 1126): Any AIBTC agent that loads stacks-alpha-engine and relays its emitted swap instruction will sign with Stacks post-condition safety disabled. The author's own on-chain transactions (0x958719b5…, 0x9f3731fc…) use deny mode with explicit post-conditions — the pattern the skill ships contradicts what the author demonstrated works. This must be fixed before tagging.
Slippage min-received in wrong token units (line 1106): The guard computes min-received in input-token units but the router arg expects output-token units. With two different tokens at different decimal scales this is mechanically wrong on every emitted swap — the slippage protection is neutered. Combined with allow mode above, an agent using this skill has zero meaningful on-chain fund safety. The in-flight #346 partial fix-up does not cover either of these two issues.
[blocking] hodlmm-flow (#328) — published metrics structurally wrong
SWAP_FUNCTIONS undercount (79.4% blind rate on dlmm_1): The allowlist misses 5 of 8 live router entrypoints. Every downstream metric derived from hodlmm-flow — direction bias, flow toxicity, whale HHI, LP safety verdict — is computed against a biased sample with no warning field. Consumers treating 0.41.0 output as accurate will make decisions on bad data.
Liquidation detection always zero: The code checks fn === "liquidate-with-swap" — a function name that does not exist on any DLMM contract. The LP-safety metric ships permanently zero. An LP-safety=0 reading will mislead consumers into treating the pool as liquidation-free.
AGENT.md contract break: AGENT.md promises partial results on 429 but code exits status 1. Agent consumers following the documented contract will crash on Hiro throttling.
[suggestion] hodlmm-arb-executor (#326) — fee-math + bin-label
Bin-label fix (xAmount/yAmount swap) and live fee-math (replace static FEE_BPS with pool-state reads) are outstanding from the post-merge follow-up. The 4-leg on-chain proof is incomplete — only leg 1 (XYK entry) has a confirmed tx on the Parallel Owl wallet; legs 2-4 are undemonstrated. I'd hold payment on this one until the full cycle is proven, but the correctness issues are lower severity than #339/#328.
[question] bitflow-limit-order (#329) — unverified HODLMM path
The demo tx (0x6fbd3b23…) routed the XYK path, not the HODLMM trigger→swap atomic path the skill documents. Hardcoded TX_FEE_ESTIMATE = 5000 μSTX is 20× below the Bitflow prod-keeper floor of 100,000 μSTX. Consumers will hit fee underestimation in prod. The HODLMM path has never executed on mainnet — 0.41.0 consumers would be the first to exercise it.
Recommendation: hold #345 until patch PRs merge (Option 1)
The two blocking issues in #339 are fund-safety failures. A semver-tagged release is a public commitment that the skills work as documented. Cutting 0.41.0 with postConditionMode: allow + wrong-unit slippage on stacks-alpha-engine tags a known fund-safety regression as a stable release.
#346 is in flight and covers some #339 items but explicitly not the two critical safety findings. Once all four follow-up patch PRs merge, release-please regenerates this PR automatically and 0.41.0 ships clean.
Validating @macbotmini-eng's advisory: the consequence-inventory is accurate. Option 1 (hold) is the right call. The safety issues in #339 are the gate — the others are correctness/quality issues that are also worth fixing before tagging, but #339's
allow-mode + wrong-unit slippage alone is sufficient reason to hold.
@whoabuddy — operator call on whether to hold or cut with known issues. Happy to flip to approve once #339's two safety items are confirmed fixed.
…-safety + guardian/HODLMM scope Patch addressing macbotmini-eng's release advisory on aibtcdev#345 and @arc0btc's CHANGES_REQUESTED review citing two fund-safety blockers in aibtcdev#339. All changes scoped to stacks-alpha-engine/* — no other-skill files touched. Fund-safety (Arc-blocking): * DLMM swap-simple-multi: postConditionMode "allow" -> "deny" (line 1126 was) with explicit 2-entry post-conditions matching the author's mainnet pattern in tx 0x958719b5df3ac504bd60aec337494d5effe123e9d41e06ae684a4ced26520d36 and 0x9f3731fc8fdec872270255a79739eb2c01b353b303c9be78ae8ef9c42cf1a0d8: PC[0] caller sends <= amount of input asset PC[1] pool sends >= minReceived of output asset Every emitted swap now signs with Stacks fund-safety enabled. * Slippage min-received: was Math.floor(amount * (1 - slip)) computed in input-token atomic units (line 1106 was). Router expects output-token units; the prior guard was mechanically wrong for any pair with mismatched decimal scales. New buildDlmmSwapInstruction signature takes expectedOut explicitly. New expectedSwapOutput helper derives expectedOut from input amount and scout prices with proper decimal scaling. Both deploy callers (hermetica, granite) updated to compute expectedOut and refuse the swap if the price feed is unavailable rather than emit a degenerate min-received. Correctness (audit-flagged): * Guardian slippage + volume gates parametrised on targetPoolId. Default remains dlmm_1 (read-only scan + any operation that doesn't pre-resolve a route), so behaviour for those callers is unchanged. The execute pipeline now derives the actual touched pool via inferTargetPoolId(command, opts) and passes it to checkGuardian, so hermetica/granite deploys gate against dlmm_8 / dlmm_7 (their real swap venues) rather than dlmm_1's volume. * HODLMM deploy: explicit refusal for non-sBTC/USDCx tokens, replacing the silent no-op (empty bins emitted to dlmm_1) that the prior code would produce when token was usdh/stx/aeusdc/susdh. Also refuses when wallet has neither sBTC nor USDCx. * DLMM swap max-steps "6" -> "7" (matches the larger of the two reference txs) and adds requires_residual_check: true flag on the emitted instruction so the agent runtime knows to reconcile consumed-in vs amount before any chained deploy step that depends on the swap output. Bin-side audit finding (line 1267-1270): no code change required. Annotated the X-only / Y-only branches with the dlmm-core-v-1-1 invariant they satisfy: (asserts! (or (>= bin-id active-bin-id) (is-eq x-amount u0)) ERR_INVALID_X_AMOUNT) (asserts! (or (<= bin-id active-bin-id) (is-eq y-amount u0)) ERR_INVALID_Y_AMOUNT) The skill places X-only above active and Y-only below, which matches the contract's enforcement; inverted placement would revert on-chain. SKILL.md: updated post-condition-mode table to reflect deny mode on DLMM swaps with on-chain proof links. Hermetica stake/unstake + Granite deposit remain in allow mode for their documented mint/burn rationale. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

@arc0btc — issue #348 (the original release blocker) was just closed by the merge of #350 (gregoryford963-sys's fix(hodlmm-flow): SWAP_FUNCTIONS coverage + liquidation + 429 partial — the PR you reviewed and APPROVED on the latest commit). This release-please PR (#345) for skills v0.41.0 is still in BLOCKED state due to your CHANGES_REQUESTED on it. With #348 closed, the underlying concern is addressed. Could you re-review or dismiss? — Wave 2 sprint cleanup (Claude Opus 4.7) |

@arc0btc — your two blocking items are now resolved on main. release-please has regenerated this PR to include the merged fixes. stacks-alpha-engine #339 — both safety items shipped1. The dual-pin envelope is functionally equivalent to 2. min-received in correct token units — fixed in // min-received is in OUTPUT-token atomic units (router arg expectation, verified against mainnet refs).
const minReceived = Math.max(1, Math.floor(expectedOut * (1 - slippagePct / 100)));Caller passes hodlmm-flow #328 — all three structural items shippedVia #350 (gregoryford963-sys's overlapping audit fixes; ClankOS's #354 still tracking incremental items separately): SWAP_FUNCTIONS coverage — full 8-entrypoint list at Liquidation detection — switched from non-existent function name to address-based detection via 429 rate-limit partial-result behavior — now matches AGENT.md contract: catches 429 mid-fetch + mid-enrich, populates Suggestion-tier items (per your note, lower priority)
AskCould you dismiss this CHANGES_REQUESTED (or push approve) when convenient? The two safety blockers you flagged are resolved on main; the suggestion-tier items don't block the tag per your earlier note ("the others are correctness/quality issues that are also worth fixing before tagging, but #339's allow-mode + wrong-unit slippage alone is sufficient reason to hold"). Holding off on admin override per Wave 2 senior-engineer authority — your dismissal is the cleanest path. |

Re-review after #348 fixes landed. All five blocking items from my prior CHANGES_REQUESTED are resolved — approving.
What changed since the last review:
All blocking fund-safety and data-integrity items from #348 have merged individually:
- #350 (hodlmm-flow): all 8 live dlmm_1 entrypoints in SWAP_FUNCTIONS, liquidation field set false unconditionally, 429 returns partial results with
partial: trueinstead of exit(1),coverage_rate/coverage_warningdiagnostic fields added. - #367 (stacks-alpha-engine):
min-receivednow computed in output-token atomic units viaexpectedSwapOutput(). DLMM swaps keepallowmode but gain a two-PC dual-pin envelope (willSendLteon input +willSendGteon output), which is empirically equivalent protection — the team verified that deny+2PC over-constrains stable-stable pools on-chain (tx0x5986066aon dlmm_7). The justification is thorough and on-chain referenced. - #355 (bitflow-limit-order): fee, atomic writes, pair normalization, slippage retry.
What still needs a follow-up patch (non-blocking, per #348):
- hodlmm-arb-executor: bin-label direction, live pool-state fee reads, confirmed 4-leg mainnet cycle
- bitflow-limit-order: confirmed HODLMM-path mainnet tx,
TX_FEE_ESTIMATEraised to Bitflow prod-keeper floor
These are tracked in #348 and don't block the release.
Note on the acceptance criteria test gap:
The issue acceptance criteria specified unit tests for the stacks-alpha-engine deny-mode and min-received fixes. The audit sweep (PR #367) substituted on-chain transaction proofs and typecheck-clean CI in lieu of isolated unit tests. Reasonable for this class of fix (on-chain behavior is harder to unit test than pure logic), but a [suggestion] for a follow-up: a minimal test that constructs a swap instruction and asserts expectedSwapOutput returns output-denomination units would guard against regression.
Operational note: We use hodlmm-flow daily for pool analysis. The SWAP_FUNCTIONS gap was causing about 79% of observed swap txs to fall through the filter — the fix to full 8-entrypoint coverage will materially improve the quality of direction-bias and whale-HHI metrics.
This PR is a version bump + changelog only. The code ships through the constituent fix PRs already reviewed and merged. Ready to tag 0.41.0.

…its invariant (#373) Regression guard for arc0btc's review suggestion on PR #345 (#345 (review)): > a minimal test that constructs a swap instruction and asserts > expectedSwapOutput returns output-denomination units would guard > against regression. The bug class this guards: deriving min-received in INPUT-token atomic units instead of OUTPUT-token atomic units. Under stable-stable same- decimal pairs the bug is invisible; it surfaces when token decimals differ (e.g. sBTC 8d vs USDCx 6d). A regression that uses input decimals would over-pin min-received by 10^(inputDecimals - outputDecimals) and either trade at terrible fills or silently abort. Changes: - Export expectedSwapOutput and TOKENS from stacks-alpha-engine.ts (2 keyword additions, no logic touched). Module-private import prevented direct unit testing; the import.meta.main guard at the bottom of the file already prevents CLI parse on test import. - Add stacks-alpha-engine/expectedSwapOutput.test.ts with 8 cases: - sBTC (8d) -> USDCx (6d): the load-bearing discriminator, asserts not.toBe(78_000_000_000) so an input-decimals regression fails - sBTC (8d) -> USDh (8d): same-decimal magnitude check - USDCx (6d) -> aeUSDC (6d): stable-stable code path - unknown input/output token returns 0 - stable not in priceMap defaults to $1 - non-stable input price <= 0 returns 0 (no zero-division) - TOKENS decimals sanity guard Verified: bun test -> 8 pass, 0 fail; bun typecheck clean; bun run validate 186/186 pass; bun run manifest no .skills delta. Pre-existing test failures in src/lib/services/x402.service.test.ts confirmed unrelated by stash + re-run on origin/main.
