* test(#3248): failing-first suite for instruction-surface disclosure 28 matrix rows from 50-test-matrix.md. Rows requiring the new Disclosure.instructionSurfaces field fail today; rows 18-20/23-25 (the ADR-2363 D4 signature invariants) pass today by construction because the current code never reads skills/agents at all, and stand as regression guards for the implementation commit. Refs #3248 * feat(#3248): disclose capability skills and agents as an instruction surface ADR-2363 D5. A capability whose only contribution was skills disclosed nothing at install: summarizeDisclosure early-returned "ships no executable surfaces (declarative only)" because hasExecutable was false, while each SKILL.md body landed verbatim in the agent's instruction context. discloseExecutableSurfaces gains a fifth, NON-executable class, instructionSurfaces, collecting declared skills/agents stems through the same safeCollect wrapper as the four existing collectors, so a hostile value degrades only this class and the function stays total for any manifest shape. Nothing existing is edited: the collectors, hasExecutable, disclosureSignature and missingArtifacts are untouched. get_impact rates the symbol CRITICAL at 196 affected, which is why the design is strictly additive. D4 is implemented by omission and pinned rather than left incidental: adding, changing or removing skills/agents leaves disclosureSignature byte-identical, so no stored consent record is perturbed and no spurious re-consent fires. ADR-2782's conditional-append trick is deliberately NOT reused - it worked because no manifest could declare a reviewer body before that class existed, whereas skills predate this one, so a conditional append would re-sign every already-consented skill-bearing capability. The renderer is extracted as summarizeInstructionSurfaces and called from BOTH branches of summarizeDisclosure. Appending only at the end would never render for skill-only capabilities - the ones that need it - since those take the early return. That branch's "declarative only" claim is now conditional on there being no instruction surface either. The renderer iterates rather than spreading into push, so an unbounded stem count cannot throw RangeError, and tolerates the bare {} the CLI edge passes via `res.disclosure || {}`. Scope note: #3248's prose says "skill stems"; ADR-2363 D3 classifies instruction surfaces as "skills, agents". Shipping skills alone would leave an ADR deliverable owned by no phase, and the epic has no Phase 2. Agents are the same shape at no extra cost. Narrowing back is a two-line change. Ratifies ADR-2363 (Proposed -> Accepted) and adds the owed ADR-1244 back-link. Closes #3248 * fix(#3248): escape consent-prompt values and narrow disclosure to skills Two review findings, both of which made the previous commit wrong. BLOCKER (isolated adversarial review). Every manifest-supplied value interpolated into a consent-prompt line was rendered unescaped. Those lines are joined with \n and written RAW to stderr on the needs-consent path (capability-command-router -> cli-exit runMain), so a stem carrying a newline forged additional lines indistinguishable from genuine GSD disclosure text, and an ANSI escape could clear or rewrite lines already printed. That defeats the informed-consent guarantee this change exists to provide, and is a prompt-injection vector against any agent that reads the stderr text to decide whether to retry with --yes. The hole was not unique to the new class - hook event/script, command family/module/router, every MCP field, and every reviewer-lane field were equally unescaped. Fixing only the new one would have created the generative-fix divergence this repo tracks, so renderValueForPrompt is applied to all five classes through one helper, guarded by a parity test that fails if a future class skips it. Escaping is identity for ordinary names, so no well-formed manifest's output changes. The disclosure OBJECT stays verbatim - only the rendered LINE is escaped - because the signature and every consumer reasoning about identity depend on the declared value. NARROWED to skills only. The previous commit also collected agents, arguing ADR-2363 D3 classifies instruction surfaces as "skills, agents". Verified against staging: stageSkillsForRuntimeAsSkills takes a registry and unions third-party skills in via readInstalledCapabilitySkill, while stageAgentsForRuntimeWithConverter takes only a source directory and has no registry-aware path. Third-party agents are never staged into the instruction context, so disclosing them would have put a false claim in a security prompt - worse than the scope creep two reviewers flagged it as. D3's classification stands; D5 now records that Phase 1 implements the skills half and that whether agents should be staged at all is an open maintainer question. Also reverts the premature ADR-2363 ratification. The previous commit flipped it to Accepted and asserted "#3248 merged" while this branch IS #3248 and is unmerged. Status returns to Proposed, and the ADR-1244 back-link - owed only on ratification - is withdrawn. Adds the fast-check property suite CLAUDE.md requires and the direct precedent (reviewer-trust-disclosure) already had: totality, D4 signature invariance, D3 hasExecutable invariance, and renderer totality over adversarial manifests. Refs #3248 * chore(#3248): correct changeset scope claim and backfill pr number The fragment was written against the pre-narrowing commit and still advertised 'skills and agents'. 4d26887e narrowed disclosure to skills only - third-party agents are never staged into the instruction context - but did not touch the fragment, so the release notes would have carried a claim the code does not implement. Also backfills pr:0 -> 3253 and names the prompt-escaping fix, which is user-visible and was absent from the original body. Changeset-only; no code or test changed, so the gsd-test pass recorded for 4d26887e still describes this tree's behavior. Refs #3248 --------- Co-authored-by: sim <sim@local>

Capability skills are now named at the install consent prompt — installing a third-party capability whose only contribution was skills printed "ships no executable surfaces (declarative only)" and listed nothing, even though each SKILL.md body lands verbatim in your agent's instruction context. The pre-install disclosure now names every contributed skill in its own section and states plainly that the bodies are not content-scanned. Values interpolated into the prompt are escaped across every disclosed surface, so a crafted name can no longer forge additional lines of disclosure text. No stored consent is disturbed and no re-consent prompt fires. (#3248)
