Works with Claude Code, Cursor, and any MCP-compatible agent. ## About ## Automation On Claude Code, a `UserPromptSubmit` hook (`hooks/refine_gate.py`, wired by this plugin's `hooks/hooks.json`) applies this skill automatically on two tiers. Codex and Gemini load the same skill explicitly or by description; their packages do not claim to install the Claude-specific hook. * **Tier 1 — reference markers**: prior-artifact shorthand, "exactly as/like", repeat-failure phrasing → inject the full binding-table instruction naming the matched marker classes. * **Tier 2 — ungrounded work request** (the generic net): the prompt asks for work (fix/build/improve/problem/bug/should/…) but contains NO concrete anchor — no file path, no commit sha, no line ref. Any named system/variable/concept ("the memory system", "the heat variable") must then be bound to its actual code artifact before reasoning. Prompts the user grounded themselves (a path in the prompt) pass through untouched. Explicit `/refine` remains for prompts both heuristics miss. ## Purpose Communication failures cost more than code failures. A terse prompt like "it must work exactly as the SSE solution" carries a precise intent that the model can mis-bind to the wrong artifact and then build the wrong thing — correctly. This skill makes the binding explicit and cheap to correct BEFORE work starts, instead of expensive to redo after. ## Procedure ### 1. Capture — never paraphrase away the original Quote the raw prompt verbatim at the top of the contract. The user's exact words are evidence; frustration markers ("still", "again", "back to square one") signal a REPEATED failure — treat those as pointers to prior attempts that must be recalled, not as noise to sanitize away. ### 2. Bind every reference — the core move Two reference classes need binding, and BOTH go in the table: **Deictic/temporal** — "it", "the X solution", "like before", "the last release", "that file", "the same way": shorthand for prior work. **Domain-entity** — "the memory system", "the wiki system", "the heat variable", "recall scores": names of systems, components, variables, and concepts. These feel concrete to the user but map to MANY possible code artifacts ("heat" alone: the memory row field, thermodynamics.py, decay_cycle.py, the WRRF heat signal, the viz heat display). Picking the wrong one solves the wrong problem correctly. For EACH reference of either class, bind it to a concrete artifact with evidence: - the memory system when available (e.g. `cortex:recall`, scoped to the project) for past decisions, RCAs, and lessons mentioning the term - `git log --oneline -15` + `git log -S""` for "the last X", "before", "the version that worked" - Grep/Glob for named-but-unlocated code ("the SSE solution" → the actual module, route, and client file) - Running processes / installed versions when the prompt says "currently", "still", "on my machine" Binding table (mandatory in the contract): | Reference in prompt | Bound to | Evidence | |---|---|---| | "the sse solution" | `/api/graph/events` + `graph_event_stream.{py,js}` | recall #4197485, grep | A load-bearing reference that cannot be bound with evidence is a STOP: ask ONE batch of clarifying questions (≤3 questions, each offering the concrete candidates found). Never guess silently on a load-bearing binding; never ask about bindings the evidence already settles. ### 3. Separate symptom from goal State, in one sentence each: - **Symptom** — what the user observes (e.g. "L6 never finishes"). - **Goal** — the end-state they want (e.g. "the full galaxy streams in real time over one connection and every node is clickable"). - **Non-goals** — what the prompt does NOT ask for (resist scope creep; list the tempting adjacent fixes being deliberately skipped). If the prompt is a question or a problem description with no change request, the contract's goal is a DIAGNOSIS, not a fix — say so. ### 4. Compile the constraints Always binding (do not restate, reference): the active coding standards — the project's `AGENTS.md`, `GEMINI.md`, `CLAUDE.md`, or lint configuration as applicable, plus the host's active user rules. Preserve size limits, no dead/unwired code, root-cause-only fixes, local reasoning, and any zetetic source discipline those rules require. Add prompt-specific constraints extracted from the user's words and from recalled lessons (e.g. "no in-between interface" → polling/ pagination layers are forbidden, not just disfavored). Quote the user's phrase next to each derived constraint so the mapping is auditable. ### 5. Select the execution strategy — research-backed, not habitual Lineage: ported from the AIPRDStrategyEngine (ai-architect-prd-builder, `packages/AIPRDStrategyEngine/Sources/Core/ResearchEvidenceDatabase*`, 15 strategies, evidence 2020–2025), then re-verified against the 2024–2026 literature (web research 2026-06-12). Zetetic corrections from that pass: the engine's CoVe attribution ("Stanford/Anthropic") is wrong — arXiv:2309.11495 is Dhuliawala et al., Meta AI/ETH; and several 2022–2023 techniques now carry measured COUNTER-evidence that the engine predates. Statuses below: **native** (the harness already does it), **confirmed** (still works as described), **caveated** (works only under conditions the original paper glossed over), **weakened** (marginal or harmful on current reasoning models). Read the bound prompt's characteristics (multi-step logic? branch exploration? accuracy-critical? example-based output? external knowledge?) and pick the matching row(s) — usually 1–2, never all: | Strategy | Use when | Evidence (2026 status) | Realization in this harness | |---|---|---|---| | context_engineering | always — the frame the others fit in | Anthropic eng. blog 2025-09-29; ACE arXiv:2510.04618 (+10.6% agents) (confirmed, current SOTA frame) | curate WHAT is in context — binding table, recalled lessons, real file contents — over wording; §§1–4 of this skill ARE context engineering | | recursive_refinement | hard reasoning, high precision | DeepSeek-R1 arXiv:2501.12948; Snell arXiv:2408.03314; survey arXiv:2512.02008: no test-time strategy universally optimal (confirmed, native) | extended thinking / higher effort on the hard subtask only | | self_consistency | one answer, several plausible derivations | Wang arXiv:2203.11171; still effective as parallel test-time scaling (arXiv:2512.02008, ST-BoN arXiv:2503.01422) (confirmed) | N independent attempts + majority/judge via parallel subagents | | verified_reasoning | accuracy-critical claims | CoVe arXiv:2309.11495 (Meta AI, not Stanford/Anthropic); BUT intrinsic self-correction degrades reasoning: Huang ICLR'24 arXiv:2310.01798, Self-Correction Bench arXiv:2507.02778 (caveated) | verify against EXTERNAL ground truth — run the test, fetch the source, measure — never by re-asking the model to double-check itself | | reflexion | retrying after failed attempts | Shinn arXiv:2303.11366; reflection without external signal is mostly confirmatory, rarely flips the answer ("First Try Matters" arXiv:2510.08308) (caveated) | feed REAL feedback — test failures, benchmark deltas, recalled failures (recall past attempts first, store the lesson after, via your memory layer when one is installed) | | tree_of_thoughts | genuinely branching solution space | Yao arXiv:2305.10601; ~100× compute vs one CoT on Game-of-24, gains shown on puzzle-class tasks (arXiv:2401.14295) (caveated: cost) | judge panel of N approaches ONLY when designs genuinely diverge; otherwise skip | | graph_of_thoughts | decompose-and-merge structure | Besta arXiv:2308.09687 (confirmed, niche) | build the dependency graph explicitly (query_workflow_graph / get_impact) before editing | | meta_prompting | task spans expert roles | Suzgun arXiv:2401.12954; BUT multi-agent often ≤ single agent — 14 failure modes, spec issues + misalignment + weak verification (MAST arXiv:2503.13657) (caveated) | route to ONE specialist with a complete role spec + verification step; don't fan out by default | | plan_and_solve | ordering-heavy multi-step work | Wang arXiv:2305.04091 (confirmed, absorbed into agentic planning) | plan mode / written plan with checkable steps | | react | interleaved reasoning + tool use | Yao arXiv:2210.03629 (native) | the agent loop IS ReAct; just act | | many_shot (was few_shot) | output format/style must match examples | Brown arXiv:2005.14165 → Many-Shot ICL arXiv:2404.11018 (NeurIPS'24 spotlight): more real examples keep helping with long context (confirmed, evolved) | paste real examples from THIS repo; scale count with context budget | | generate_knowledge | missing domain facts | Liu arXiv:2110.08387 (weakened: parametric generation hallucinates; superseded by retrieval) | RETRIEVE, don't generate: your memory layer's recall (when installed), read the actual paper/source — knowledge from a vacuum is the failure mode §8 of coding-standards forbids | | multimodal_cot | visual evidence | Zhang arXiv:2302.00923 (native multimodality) | read the actual image/screenshot; verify UI claims by looking | | chain_of_thought | explicit audit trail wanted | Wei-era CoT now marginal on reasoning models: +2.9–3.1% at 20–80% time cost (Wharton GAIL 2025); HARMS some task classes, −36.3% o1-preview on implicit statistical learning (arXiv:2410.21333); models reason unprompted (arXiv:2402.10200) (weakened) | don't inject "think step by step"; write the derivation out only when the USER needs the audit trail | | problem_analysis | tangled symptom, unclear decomposition | engine-internal (no arXiv); closest sourced umbrella: decomposition class in The Prompt Report arXiv:2406.06608 (weakest row) | §§2–3 of this skill: binding + symptom/goal split IS the decomposition | | auto_optimization | a RECURRING prompt/pipeline worth tuning | GEPA arXiv:2507.19457 (ICLR'26 oral): reflective prompt evolution beats MIPROv2 by 10–14%, 35× fewer rollouts than GRPO (confirmed, new) | for repeated prompts (hooks, pipelines, skills): optimize against an eval set programmatically, don't hand-tune by vibes | | zero_shot | trivial, single-step, well-specified | baseline; scaffolding simple tasks degrades output (arXiv:2410.21333) | just do it | Selection rules (engine's ResearchWeightedSelector, updated 2026): 1. Match characteristics; never stack strategies the task doesn't exhibit — scaffolding is now MEASURED to harm some task classes, not just waste tokens. 2. Prefer external feedback over intrinsic reflection — the model re-checking itself without new evidence degrades reasoning (arXiv:2310.01798). Tests, benchmarks, sources, and tools are the feedback channel. 3. No test-time strategy is universally optimal (arXiv:2512.02008); when evidence conflicts or the task is trivial, zero_shot wins. 4. This table is a snapshot (verified 2026-06-12). Newer technique with better evidence → use it AND update this table with the citation. ### 6. Define acceptance criteria — external signals or it doesn't count Each criterion is a command or observation that can pass/fail INDEPENDENTLY of the model's own judgment. Intrinsic self-checking ("re-read your answer and confirm it's right") measurably degrades reasoning (arXiv:2310.01798) and reflection without new evidence is mostly confirmatory (arXiv:2510.08308) — so a criterion the model grades by introspection is not a criterion: - the reproduction case, and the command that proves it fixed - tests that must pass (name the suites) - measured numbers where performance is the complaint (before/after) - a fetched source / document for factual claims - "would a staff engineer approve this?" is the floor, not the bar ### 7. Echo, then execute Print the compiled contract compactly (≤30 lines). If every load-bearing reference is bound and no blocking ambiguity remains, EXECUTE immediately under the contract — do not ask for permission to do what was asked. If executing, verify each acceptance criterion at the end and report pass/fail explicitly. ### 8. Close the loop After execution (or after the user corrects a binding), store the raw phrase → correct binding pair via your memory layer's remember tool when one is installed (e.g. `cortex:remember`, tags: ["archival", "lesson", "prompt-binding"], agent_topic scoped), so the next session binds it instantly; without a memory layer, note it in the project's own durable instructions or documentation. Mis-bindings the user had to correct are the highest-value memories this skill produces. ## Failure modes this skill exists to prevent | Failure | Gate | |---|---| | Solving the wrong problem confidently | §2 binding table + §3 symptom/goal split | | Dead or unwired code | §4 standards + §6 "must be called" criterion | | Band-aid at the throw site | §4 root-cause rule; RCA before fix in §3 | | Non-scalable hot path | §6 measured numbers when perf is the complaint | | Unreadable output | §4 size limits / naming rules | | Re-losing corrected intent | §8 phrase→binding memory | | Self-verification theater (model grading itself) | §6 external-signal criteria (arXiv:2310.01798) | | Habitual scaffolding on simple tasks | §5 rules 1+3 — zero_shot wins (arXiv:2410.21333) | ## Example Raw: *"we're back to square one, graph L6 not finishing, must work exactly as the sse solution, not in between interface"* Bound: "square one" → prior session RCA (recall); "the sse solution" → `/api/graph/events` + `GraphEventStream` (grep + recall); "in between interface" → the polling phase loader in `unified-viz.html` (git log). Goal: SSE is the ONLY delivery path, L6 completes, nodes browsable. Acceptance: build reaches `full_ready` with symbols; SSE replay ends in `done`; `/api/graph/node` returns `found:true` for a symbol id. ## Source & license This open-source skill is cataloged on AgentStack and links to its original source — we do not rehost the code. - **Author:** [cdeust](https://github.com/cdeust) - **Source:** [cdeust/session-optimizer](https://github.com/cdeust/session-optimizer) - **License:** MIT - **Homepage:** https://ai-architect.tools Install and usage instructions live in the source repository linked above. ## Pricing - **Free** — Free ## Security capabilities Automated source analysis of v0.1.0 — what this tool can access: - **Network access:** no - **Filesystem access:** no - **Shell / process execution:** no - **Environment & secrets:** no - **Dynamic code execution:** no *"Yes" means the capability is present in the source — more access means more to trust, not that it is unsafe.* ## Versions - **0.1.0** — security scan: passed — Imported from the upstream source. ## Links - Listing page: https://agentstack.voostack.com/l/skill-cdeust-session-optimizer-refine - Seller: https://agentstack.voostack.com/s/cdeust - Browse the marketplace: https://agentstack.voostack.com/browse --- Listed on AgentStack — the marketplace for AI agent skills and MCP servers.
