* docs: mark the 2026-09-08 stable-spec decision Accepted
Its text already shipped in specification/stable/skills.mdx via PR #139, so
the entry joins the three v1 entries this PR ratifies.

* docs: point README and AGENTS.md at the released spec and official docs
SEP-2640 is Final and the extension ships from specification/stable/skills.mdx,
so the README now leads with a Specification section linking the spec file,
the official docs page (modelcontextprotocol.io/extensions/skills/overview),
the published SEP, and the client matrix. The experimental banner is replaced
with a note that docs/ holds working documents; the charter, pulls, and issues
links move off the redirecting experimental-ext-skills / charter URLs.
AGENTS.md no longer names the SEP PR as the source of truth; it points agents
at the stable spec page and describes the decision-log flow against that file.

* docs: accepted spec changes land in a draft revision, not the stable file
The stable specification is a released snapshot. README and AGENTS.md now say
accepted decision-log proposals go into a draft revision that ships as a new
release, matching the ext-tasks specification layout.

* docs: move pre-release design documents to docs/archive
SEP-2640 is Final, so docs/ now holds only living working documents. Eight
historical documents move to docs/archive with an index explaining what each
was and what superseded it: the SEP baseline copy, why-and-when, use-cases,
approaches, skill-uri-scheme, glossary, client-mcp-support (superseded by the
official client matrix), and agent-plugins-analysis.
Files the published SEP links to by path (decisions, experimental-findings,
open-questions, problem-statement, rationale, related-work, skill-meta-keys)
stay in place so those links keep working. Cross-links are rewritten and
verified; the README contents table is trimmed to match.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
* docs: archive open-questions and skill-meta-keys
Both are pre-release documents whose outcomes live in the decision log and
the specification. The published SEP links to them by path; a companion
change in modelcontextprotocol/modelcontextprotocol repoints those links.

* docs: fix sibling links inside archived open-questions and skill-meta-keys
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
* docs: keep only the decision log and rationale in docs/
threat-model, experimental-findings, findings-template, problem-statement,
and related-work move to docs/archive with index rows. The candidates
tracker and the archived client-support survey are removed in favor of the
official extension client matrix, and links to them are repointed there.
README drops the Why and Problem Statement sections, which duplicate the
SEP's Motivation and the official overview page. CONTRIBUTING routes new
implementation findings to GitHub issues.

* docs: replace the interim reference package with the TypeScript SDK row
The @olaservo/ext-skills package is retired in favor of first-class skills
APIs in the TypeScript SDK (typescript-sdk#2798, phase 1 in #2818). The
archived related-work page now points at implementations.md for current
information.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
* docs: drop pre-SEP rows from the implementations list
They are already recorded in the archived related-work page; the list now
points there instead. FastMCP stays because its row tracks the migration to v1.

* docs: add official SDK progress, Tachyon, and Inspector 2.6.0 to implementations
From the WG Discord channel and the SDK repos as of 2026-09-15: Go, TypeScript,
Python, and C# SDKs all have open SEP-2640 PRs (Go passes conformance); the
conformance suite merged; Inspector 2.6.0 shipped skills verification; Tachyon
reports a server implementation. Adds an "in progress" status for open PRs.

* docs: sync repo SEP copy with canonical v1 text
The repo-local copy of SEP-2640 had drifted well behind the canonical
text on the sep/skills-extension branch, which was a source of
confusion: it still specified the well-known skill://index.json
resource and predated skills/list, skills/get,
resources/directory/read, nested skills, and per-file digests.
Replace the body with a verbatim copy of the canonical SEP as of
d7490ec (2026-07-15) and swap the stale "not actively maintained"
notice for a disclaimer that states what this file now is: a synced
snapshot, re-synced by overwriting rather than hand-editing, with
review on the upstream PR and anything beyond v1 raised as a PR in
this repository.
Also drop "working draft" from the README and related-work references
to this file, since it is no longer where the text is drafted.
* docs: frame the SEP copy as the v1 baseline for decision-log proposals
The previous note told readers not to propose changes here at all, which
is the wrong instruction: the WG does want to propose beyond v1, just in
this repo rather than on the upstream SEP.
Reframe the file as the v1 baseline and route proposals through the
existing decision log rather than a parallel mechanism. decisions.md
already carries the ADR-lite format, the Proposed/Accepted/Superseded
status idiom, and the precedent for consolidating a version's scope into
one record (the 2026-07-16 v1 entry), so a change beyond v1 is simply the
next dated entry. The note also defines the marker that ties an amended
section back to its record, so v1 text stays distinguishable from
accepted deltas as the document accumulates them.
Align the README and related-work references to the same framing.
* docs: mark the 2026-04-16 URI decision superseded in part
Every other decision the v1 scope-down changed carries a forward pointer
in its status line (2026-04-19, 2026-06-02, 2026-06-05, 2026-06-09). The
2026-04-16 URI entry was left as plain Accepted while three of its
bullets no longer hold, so it reads as current guidance for index.json
enumeration and the no-nesting rule.
Give it the same treatment, naming which bullets changed and which parts
of the URI convention carry forward, so the entry stays useful as a
record of the structure it settled.
* docs: add AGENTS.md and make the SEP PR link prominent
Readers were landing on the repo-local SEP copy and taking it for the
spec, which is how the stale version misled people in the first place.
Say plainly, in the places they land, that the v1 spec text lives on
modelcontextprotocol#2640:
- README: a source-of-truth line at the top of the link block, above
the charter.
- The baseline copy: lead the header note with the PR rather than
mentioning it mid-paragraph.
- AGENTS.md: state the rule for agents working in this repo, along with
how to propose beyond v1 via the decision log and the repo's markdown
conventions.
CLAUDE.md is a one-line pointer to AGENTS.md rather than a symlink, so
it resolves on Windows checkouts too, where symlinks need Developer Mode
and would otherwise land as a stub.
* docs: use the @AGENTS.md import in CLAUDE.md
A markdown link is not an import — Claude Code would have loaded the
pointer line and never expanded AGENTS.md into context. The documented
syntax is @path, which the docs specifically recommend over a symlink
on Windows, where symlinks need Administrator privileges or Developer
Mode.
The maintainer note is a block-level HTML comment, which Claude Code
strips before injecting the file, so it costs no context while staying
visible to anyone opening the file.
https://code.claude.com/docs/en/memory#agents-md
* docs: tighten AGENTS.md to the source-of-truth rule
Cut the project overview and conventions sections and lead with what an
agent most needs to get right: the v1 spec text is on the PR, and the
copy here is only as current as its pinned commit. CONTRIBUTING.md
already covers participation and process.
* docs: record SEP-2640 v1 scope-down and skills/get as decision records
Consolidates the July 2026 rework of SEP-2640 (post June 24 CM deferral
and June 30 WG scoping decision) into a single ADR for group review:
archives removed, skills/list replacing skill://index.json, per-file
resources manifest, optional directory read, non-privileged schemes,
name-collision handling, and nested-skill consent gating.
Adds a separate ADR for the skills/get method proposed by @aditya-scio
in SEP review, and updates the status lines of the four prior entries
this rework supersedes or amends (2026-04-19, 2026-06-02, 2026-06-05,
2026-06-09).

* docs: add Discord design-thread references to v1 scope-down ADR
Links Peter's July 8 change announcement, the supporting-file digests
thread (the design discussion behind the per-file resources manifest),
and Sambhav's June 24 method-family sketch that prefigured skills/list
and skills/get.

* docs: refine context and rationale for skills/get method in SEP-2640 decision
Records the 2026-06-09 decision (SEP-2640) to add a dedicated
resources/directory/read method for listing directory-like resource
children, identified by the inode/directory mimeType and returning a
paginated, metadata-only Resource list. Captures the rejected
alternatives (overloading resources/read by mimeType; adding a uri
param to resources/list) and the rationale for a dedicated verb.
Status: Proposed.

* docs: add ADR for filesystem as host-side implementation detail
Record the proposed decision that skills served over MCP MUST function
without a local filesystem, while hosts MAY materialize resources as an
optimization, with unified resolution semantics required either way.

* docs: add decision record for archive distribution type
Formalizes the April 18 decision to permit type: "archive" entries in
skill://index.json as a server-side packaging optimization, reinstating
symmetry with the Agent Skills discovery RFC.
* docs: correct decision record date to 2026-04-19
* docs: add permissions/symlinks motivation and issue #61 reference
* docs: log URI scheme decision for skill resources
Backfills a decision-log entry for the `skill://` URI convention
adopted via PR #70. Captures the convergence signal, the key
reversal (decoupling path from skill name), and notes the month-long
open-review period on GitHub and in Discord.

* docs: update rationale for URI scheme decision to clarify discussion context
* docs: broaden URI scheme decision to cover domain-specific schemes
Acknowledges implementations that used domain-specific URI schemes
alongside skill://, and frames the adopted pattern as a recommended
convention rather than a universal rule.
* docs: align URI scheme decision with SEP draft's final position
Updates the 2026-04-16 URI scheme entry to reflect where the draft SEP
actually landed rather than the survey's earlier recommendation:
- Final path segment MUST equal the skill's frontmatter name (not fully
decoupled). Prefix segments remain server-chosen.
- Enumeration is via the well-known skill://index.json resource, not
scoped resources/list.
- Domain-specific URI schemes are permitted when indexed, which the
earlier wording placed in Context as observed convergence rather than
as an allowed Decision point.
- No-nesting phrasing aligned with the SEP ("descendant directory of
a skill").
Context also restored to the survey's four-implementations framing.
* docs: restore Context framing on URI scheme decision
Restores the earlier "Several...etc." wording and "Resources to
represent skills" framing in Context; keeps the SEP-structural edits
(final-segment-equals-name, index.json, domain-specific schemes).
* docs: calibrate enumeration wording to match SEP SHOULD level
The SEP specifies servers SHOULD expose skill://index.json, with an
explicit escape hatch for unenumerable catalogs. Previous wording used
RFC 2119 OPTIONAL which understated the recommendation. Also notes
alignment with the Agent Skills well-known URI index format and folds
template entries into the enumeration bullet where they belong.

* docs: transition from Interest Group to Working Group
Follow-up to modelcontextprotocol/modelcontextprotocol#2586, which
converted the charter from IG to WG.
- Rename Interest Group → Working Group in headings and prose
- Update Discord (#skills-over-mcp-wg) and Discussions
(meeting-notes-skills-over-mcp-wg) references; channel renames
coordinated separately
- CONTRIBUTING.md: align meeting norms with MCP group governance
(7-day advance notice, meet.modelcontextprotocol.io) and rewrite
Decision-Making to reflect WG authority (lazy consensus → formal
vote → escalation), linking to the charter's Authority table
- Keep CODEOWNERS team at skills-over-mcp-ig pending access-repo
rename; TODO comment added
- decisions.md: update present-tense preamble, log the IG → WG
transition as a new ADR entry, and preserve historical entries

* docs(contributing): link to governance/charter instead of duplicating
Meetings and Decision-Making sections now point to the MCP group

IG-era phrase in the Decision Log guidelines.
