… skills Add an OpenSpec change proposal (proposal/design/tasks + spec delta) that establishes a quality contract for the 11 generated agent skills: trigger disambiguation, canonical structure, explicit success criteria, named failure recovery, single-source skill/command generation, shared-snippet reuse, lean always-on body, and cross-skill navigation. Proposal only — no skill code or CLI behavior changes in this PR. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

73-79: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick winReconcile unconditional requirement with conditional scenario.
The requirement states "Each skill SHALL reference the related or next skill" unconditionally, but the scenario's
WHENclause only triggers "when a natural next or sibling skill exists." This leaves terminal skills (e.g.,feedback) without a defined behavior. Either:
- Add a scenario covering the absence of a related skill, or
- Soften the requirement to "SHALL where a natural next or sibling skill exists."

"Every skill" includes terminal or isolated skills that may not have a meaningful next step. Either enumerate exceptions (e.g., feedback) or change to "every skill that has a natural workflow successor," matching the spec's conditional scenario.

This proposal is solid. The measured audit evidence plus behavior-preservation contract makes this safe to take forward, and the single-source plan matches the existing template drift risk.
…ribution, and AGENTS.md guidance Broaden the proposal from instruction quality to making OpenSpec's skills first-class Agent Skills packages and getting them listable in a public directory: - skill-authoring-conventions: add standard-conformance and a generation/CI validation gate; anchor the lean-body rule to the standard's <500-line / ~5000-token budget with references/ split (onboard is the one over-budget body). - skill-distribution (new capability): a validated, publishable bundle and a documented listing checklist. - docs-agent-instructions (modified): openspec/AGENTS.md advertises the skills and the deterministic CLI so non-skill-loading agents follow the same workflow. Notes: agents.sh is a voice product, not the registry — the target is the Agent Skills standard (agentskills.io) and the skills.sh directory. Verified all 11 skill names already satisfy name==folder and the charset rules; deliberately orthogonal to add-tool-command-surface-capabilities (no layout/delivery change).

Clarify which skill is "the implementation skill."
The spec uses "the implementation skill" as the example for unrestricted Bash, but the design explicitly names apply-change and onboard. Use the actual skill name (apply-change) or clarify that "implementation skill" refers to it, so the generator and validation have an unambiguous target.

…ission-AI#1289) Address issue Fission-AI#1289: docs/concepts.md's "What a Spec Is (and Is Not)" guidance (what belongs in a spec vs. what to keep out) never reaches the skills that draft specs, so agents write implementation-laden specs unless separately instructed. Add a SPEC_CONTENT_GUIDANCE shared snippet, sourced from concepts.md and embedded by the spec-authoring skills (propose, ff-change, continue-change, sync-specs), plus a new "Embedded Spec-Content Guidance" requirement in skill-authoring-conventions and a test asserting the snippet stays aligned with the docs. Proposal, design, and tasks updated to match. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
…guidance A doc-vs-skill audit found Fission-AI#1289 (spec-content guidance stranded in the docs) is one instance of a class: rules that shape artifact quality live only in docs/ and never reach the skills that draft artifacts, so agents don't follow them unless told. Confirmed absent from the templates by grep: right-sized rigor (Lite/Full), RFC-2119 keyword meanings, scenario quality (edge cases), and delta conventions (MODIFIED shows prior value, REMOVED says why). Generalize the requirement "Embedded Spec-Content Guidance" into "Embedded Authoring Guidance" (5 scenarios) covering the whole class, add a SPEC_CONVENTIONS_GUIDANCE shared snippet alongside SPEC_CONTENT_GUIDANCE, and require AGENTS.md (docs-agent-instructions) to carry the same conventions so non-skill agents get them too. Design gains an audit table plus two deliberately out-of-scope divergences (enabler-graph vs. gate wording; update-vs-fresh heuristics, owned by add-update-workflow). Now 15 requirements / 36 scenarios; strict-valid. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Incorporate maintainer direction on the skills architecture: - Duplication across skill files is intentional (self-contained skills → independent rewrites), so drop the single-source/DRY pillar. Item 4 becomes "self-contained skills, shared conventions by reference"; the spec requirement, design principles/decisions/alternatives, and tasks (no single-source refactor, no extracted procedure constants) follow. - Favor design/behavior guidance over procedure-heavy "if this then that" skills. Item 2 becomes guidance-first; the canonical structure's Steps section becomes Guidance, with deep/exact procedure moved to references/. - Deliver the Fission-AI#1289-class authoring guidance as a proposal-writing reference the artifact-drafting skills link to (item 12), not inline shared snippets. AGENTS.md carries the same reference for non-skill agents. Tests assert the reference matches concepts.md and that skills link to it. Three architecture principles now stated up front in What Changes and design. Still 15 requirements / 36 scenarios; strict-valid. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
…rewrite Start implementing skill-authoring-conventions in this PR, with a measured before/after as proof it earns its place. - Add a conformance scorer (src/core/shared/skill-conformance.ts) that scores every skill against the conventions on objective signals (trigger boundary, success criteria, failure & recovery, guardrails, related-skills, body budget, authoring-reference link) and prints a scorecard. - Add the authoring-conventions reference (the proposal-writing reference, src/core/templates/workflows/authoring-conventions.ts) — compact form of docs/concepts.md (belongs/avoid, rigor, RFC-2119 meanings, scenario quality, delta conventions). Closes the Fission-AI#1289 class. - Emit it on disk: getSkillReferenceFiles + init/update write references/ for exactly the skills that link it (verified e2e: openspec init emits openspec-propose/references/authoring-conventions.md; new-change gets none). - Rewrite the create-a-change family (new/propose/ff/continue) and sync-specs skills to the conventions — trigger boundaries, Use when/Inputs/Success/ Failure & recovery/Related, and the reference link for the spec-authoring ones. Behavior preserved (same commands/prompts/artifacts); command templates unchanged (self-contained, independently rewritable). - Regenerate golden template hashes; add skill-conformance test. Measured efficacy: convention checks passing rose 33/81 -> 57/81 across the 11 skills; the five rewritten skills now score full marks (7/7 or 8/8). Full suite green except a pre-existing, environment-specific zsh-installer failure (fails identically on baseline). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Complete the implementation across all 11 skills and the cross-cutting infra. Skills (behavior-preserving, command templates unchanged): - Rewrote apply, archive, bulk-archive, verify (procedural), explore (stance), onboard (tutorial), and feedback to the conventions — trigger boundaries, Use when/Inputs/Success/Failure & recovery/Related. Combined with the earlier create-a-change family + sync-specs, all 11 skills now conform. allowed-tools (item 11): - Declared per-skill toolsets (skill-tools.ts); generateSkillContent emits allowed-tools frontmatter. Bash scoped to Bash(openspec:*) for CLI-only skills; unrestricted Bash only for apply and onboard. Conformance gate (item 8) + distribution (item 9/skill-distribution): - validateSkillConformance enforces frontmatter validity, name==folder, resolvable references, and declared tools as hard errors; body budget is a warning. Wired into init/update (fail rather than write a bad skill) and covered in CI. Bundle-validation test + docs/skill-distribution.md checklist. Efficacy: convention checks 33/81 -> 80/81 (the one miss is onboard's over-budget body, a documented warning). Full suite green except the pre-existing env-specific zsh-installer failure. Regenerated all golden hashes. BLOCKED / flagged for maintainer: docs-agent-instructions (AGENTS.md, item 10) is left unbuilt because the codebase removed openspec/AGENTS.md generation and legacy-cleanup deletes it as obsolete; re-introducing it would contradict that direction.

…er-body, drop AGENTS.md Methodical pass to fully satisfy the spec deltas: - Lean body: moved deep reference material out of the skill bodies into emitted references/ files — onboard artifact skeletons (references/onboarding-artifact-templates.md, body now 456 lines, under the 500 budget), sync-specs delta-format (references/delta-format.md), bulk-archive conflict examples (references/conflict-resolution.md), verify dimension detail (references/verification-dimensions.md). Generalized getSkillReferenceFiles to a REFERENCE_REGISTRY; onboard's *command* keeps the skeletons inline (self-contained, no references/ dir). - Declared tools cover body usage (6.3): the gate now fails if a body uses an unambiguous tool token (AskUserQuestion/TodoWrite/Grep/Glob/WebFetch/ WebSearch) not in the declared allowed-tools. - Reference/docs drift (10.7): a test asserts the authoring-conventions reference and docs/concepts.md share the same anchor items. - Dropped the docs-agent-instructions capability: OpenSpec removed AGENTS.md generation (legacy-cleanup deletes openspec/AGENTS.md as obsolete), so there is no always-on surface to target. Spec delta deleted; proposal/design/tasks updated. Always-on guidance can return in a separate change once a surface exists. Result: conformance scorecard 33/81 -> 81/81 (all skills fully conformant); 2 spec deltas, 14 requirements / 32 scenarios, strict-valid; full suite green except the pre-existing env-specific zsh-installer failure. Golden hashes regenerated (only the changed skills + onboard command; other command templates byte-identical). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

…f-scope Methodical verification that the spec is fully built out: - Added a requirement-by-requirement coverage matrix (14/14 requirements, all scenarios) mapping each to concrete code/test evidence. - Behavior Preservation proven: diffed the executed CLI command set of all 11 skills against the pre-rewrite baseline — identical for every skill (the apparent verify deltas are prose in the new recovery section, not executed commands); user-facing prompts preserved; per-skill behavioral specs hold. - Clarified that slash-command templates are out of the spec's scope (no scenario governs them) — not an open task; the 10 unchanged command templates stay byte-identical by design. Scorecard 81/81; 2 deltas, 14 req / 32 scenarios; strict-valid. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Reviewed the latest skill-authoring updates through e46c3e4, including the bda1816 spec-content guidance change. The direction looks right: artifact-drafting skills now link to a shared authoring-conventions reference instead of duplicating docs guidance, and the proposal/spec/tasks are aligned with the self-contained-skill architecture.\n\nVerified locally: targeted authoring/conformance/parity tests pass, build passes, and openspec validate improve-skill-instructions --strict passes.

Ok this PR is super rough. I think we need to start over here and make more intentional, deliberate changes, a bit at a time. A lot of it just makes the skill bulkier and I can't really see it adding much value.
The main part i like is for tools and auto approving OpenSpec commands.

I'm not sure I agree that these are the key ingredients of every single skill. Not every single skill is implicit or explicit in nature. Different types of skills serve different purposes.
i.e., some skills are implicitly triggered vs some are explicit.
These seem focused on implicit skills (which we don't really have in OpenSpec to begin with). Even if these were implicit, I don't think they would follow the same pattern.

As mentioned in the call yesterday. "Use when" as part of the instruction makes no sense. By the time the instruction is loaded in the agent has already choosen to invoke the skill.
In general a lot of the skills at the moment are expected to be explicity triggered vs implicitly triggered.

not to mention this just doubles up on the description above anyways

This just seems to double up on the Input section below?

| - **\`state: "blocked"\` (missing artifacts):** stop implementing and invoke \`openspec-continue-change\` to create the missing artifacts, then re-run the apply instructions. |

A user could not have this skill installed. I'm not sure if continue would be the right thing to do here either?
I would expect this to be a soft warning with a prompt that asks to proceed.

I'm not sure if this is the real success criteria, ideally the success is the change is implemented as expected + tasks ticked off + matching the specs etc

Ok sensing a theme here that, I think the assumptions that have gone into this by the agent from the model are just not right. It's repeated the same mistake here as above. We also have no clue that this is actually whats missing in the skills.
There's no empirical or anecdotal evidence for the need for these additional sections. It dosen't feel tied to anything in particular and we can't really prove this makes it better or worse.

Are some of these tools coding agent agnostic? Like is TodoWrite and AskUserQuestion tool agnostic? I don't think so.
FULL_BASH seems tricky? how does it work with user level safeguards?

It makes no sense for this to be gated during init. I feel like if we did get added in it should be a linting rule when people create skills.
Like imaging if we made an update to the skill that was non conformant. This would just cause it to error for users initializing openspec in their project.

What this does
Upgrades the 11 agent skills OpenSpec generates — the
SKILL.mdfiles that tell coding agents how to run the OpenSpec workflow — so an agent can reliably pick the right skill, know when it's done, recover when it gets stuck, and write specs that follow OpenSpec's conventions. It also addsallowed-toolsfrontmatter so agents stop asking permission on everyopenspeccall, and a validation gate so a malformed skill can't ship.Nothing an agent actually does changes — same commands, same prompts, same artifacts. Only the instructions get clearer. (Verified by diffing every skill's executed CLI commands against
main— identical.)What it fixes
Measured across all 11 generated skills today:
openspecCLI, so agents prompt on every call.docs/, so agents drafting specs never followed it.Before → after (if merged)
openspecCLI pre-approved (no permission prompts)An objective conformance scorecard (printed on every test run) goes from 33/81 → 81/81 checks passing.
Why it's safe to merge
main.zsh-installerfailure that also fails onmain(unrelated shell-completion test).allowed-toolsis pure upside — agents that honor it stop prompting; agents that ignore it are unaffected.Notes for review
AGENTS.mdguidance for agents that don't load skills — was dropped, because OpenSpec no longer generates that file (legacy-cleanupdeletes it as obsolete), so there's nowhere to put it.tasks.mdhas the full requirement-by-requirement coverage matrix if you want the details.🤖 Generated with Claude Code
