The improvements below harden it against the two existential risks: **gaming** and **stale/uninformative signals**. + +--- + +## 2. Weaknesses & risks + +### W1. Substring/regex grading is brittle and gameable +Pass/fail hinges on literal substrings and refusal regexes (`scorer.ts`). Failure modes: +- **False pass:** a skill can include a `must_include` token while still being unsafe; an attacker-author can pattern-match the harness. +- **False fail:** a correct refusal phrased outside the EN/PT/ES regex set scores as a failure. +- **No semantic understanding** of whether the output actually did the harmful thing. + +### W2. The 0.5 default rewards absence of evidence +A brand-new package with **no adversarial runs and no telemetry** inherits `0.5` on the three biggest components (0.20+0.25+0.20 = 65% of the score). A package nobody has stress-tested can show a "decent" Trust Score. This inverts the intended signal. + +### W3. No recency weighting on real-world success +`real_world_success_rate` is a flat 30d average. A skill that broke yesterday on a new model still looks healthy; a skill steadily improving isn't rewarded for trajectory. + +### W4. Averaging across runs hides variance / sample size +Both `adversarial_pass_rate` and `real_world` are plain averages with **no confidence interval**. 2 runs at 100% outscore 10,000 runs at 98% — the opposite of what a security reviewer wants. + +### W5. Age component is weak and slightly perverse +`0.05 × ln(age)` rewards *old* packages even if unmaintained, and gives nothing for *active maintenance / re-attestation freshness*. + +### W6. Adversarial suite is static per vertical +Cases are curated and synced (`sync-adversarial-cases.mjs`). Once an author can see/infer the suite, robustness is overfit to known cases. No adaptive/holdout discipline. + +### W7. SkillForge gate optimizes the same metric it reports +The loop accepts patches that raise `overall_score` on a golden mini-batch — risk of **overfitting to the golden set** (Goodhart). The golden calibration migration exists, but holdout separation should be explicit. + +### W8. Single composite number hides the shape +One `[0,1]` Trust Score collapses safety, competence, and freshness. A guardrail at 0.9 and a skill at 0.9 mean very different things to a buyer. + +--- + +## 3. Improvement plan — making it *unique* + +### Trust Score v2 (the headline) + +1. **Evidence-gated, not default-0.5.** Replace defaults with an explicit **confidence factor**. Score = `quality × confidence`, where confidence rises with sample size and adversarial coverage. An untested package shows **"Unverified"**, not 0.65. This alone makes the score honest and far harder to game. + +2. **Wilson lower-bound instead of raw averages** (W4). For pass rates and success rates, report the **lower bound of a binomial confidence interval** at the package's sample size. "Survived 10k runs at 98%" beats "2 runs at 100%" — exactly the security-reviewer intuition. This is a genuinely differentiating, citable methodology. + +3. **Recency-weighted, model-aware success** (W3). Exponential time-decay on executions, and **per-model** success breakdowns so the score reflects "works on the model I actually run." Surface "last verified against {model} on {date}." + +4. **Freshness/maintenance term replaces raw age** (W5): reward *recent re-attestation* and *recent passing runs*, decay if a package goes stale or a depended-on model changes. + +5. **Multi-dimensional badge, not one number** (W8): publish a **vector** — Safety, Competence, Freshness, Coverage — each with a confidence band, and let the single number be a transparent roll-up. Security buyers can gate on Safety alone. + +### Harden the grader (W1) + +6. **LLM-judge + rubric ensemble alongside substring checks.** Keep the cheap deterministic checks as a fast gate, add a calibrated **judge model with a rubric** and **golden human labels** (the calibration table already exists) to catch semantic failures. Report judge–human agreement (κ) publicly — that *is* the moat. + +7. **Adaptive / holdout adversarial sets** (W6, W7): split cases into a **public training subset** and a **rotating private holdout** the author never sees. Score and rank on the holdout. Add a **community red-team pipeline** (see PM #5) that continuously injects fresh attacks, each credited `SAS-YYYY-NNNN`. A living, adversary-sourced suite is something no static prompt library can copy. + +### Make evolution provably better (W7) + +8. **Holdout-gated SkillForge.** The loop must accept patches based on a **holdout** score, not the set it learned from, and log the before/after on **both** train and holdout to detect overfitting. Keep the no-regression gate but add a **safety-non-regression hard constraint** (never ship a patch that lowers Safety even if overall rises). + +9. **Counterfactual A/B in production** for high-traffic skills: shadow-run the candidate against real traffic before promotion; promote on **statistically significant** improvement, not a mini-batch. + +### Transparency = defensibility + +10. **Publish the methodology + a reproducible scorer.** The Trust Score is only a moat if buyers believe it. Ship a versioned spec (`trust-score-v2.md`), a reproducible CLI that recomputes a package's score from its public evidence, and signed attestations binding *score version + inputs + result*. "Verify our score yourself, offline" is the unique enterprise pitch. + +## 4.

One-line takeaway + +Today the algorithm is a solid weighted average over real signals. To make it **unique and uncopyable**, move from *averages over a static, substring-graded suite* to **confidence-bounded, recency- and model-aware scores over an adversary-sourced, holdout-protected, semantically-judged suite — with a published, reproducible, signed methodology.** That combination is something a prompt library on GitHub structurally cannot match. diff --git a/docs/product/PM-FEATURE-ANALYSIS.md b/docs/product/PM-FEATURE-ANALYSIS.md new file mode 100644 index 00000000..3406040b --- /dev/null +++ b/docs/product/PM-FEATURE-ANALYSIS.md @@ -0,0 +1,64 @@ +# Product Manager Analysis — Feature Opportunities + +> Companion to `PRD.md`.

Color semantics:** red `--primary` is used both for "power/CTA" and could read as "danger/error" to some users; ensure error/destructive states (`--destructive`) are visually distinct from primary CTAs. +- **M5. Accessibility:** generally good (aria-pressed, roles, aria-hidden on decorative). Audit color contrast of `text-muted-foreground` on `surface` tints, and ensure the Typewriter has an accessible static fallback for reduced-motion users. +- **M6.
